The strongback umbilical tower at pad 39A is retracting into position for engine start, suggesting the hold-down firing of the Falcon 9 rocket's nine first stage Merlin engines remains on track for 10:10 a.m. EST (1510 GMT).

This firing will last several seconds as the rocket ramps up to 1.7 million pounds of thrust, while hold-down restraints keep the Falcon 9 on the ground.

SpaceX fired up nine Merlin main engines at the bottom of a previously-flown Falcon 9 booster Saturday at NASA's Kennedy Space Center, running the rocket through a practice countdown before a scheduled liftoff Jan. 18 with a Crew Dragon capsule to test the human-rated ship's high-altitude abort capability.

The Falcon 9 rocket's nine Merlin 1D engines ignited at 10:10 a.m. EST (1510 GMT) Saturday as hold-down clamps kept the rocket firmly grounded at launch pad 39A.

The test-firing lasted for several seconds as the Merlin engines powered up to full throttle to produce 1.7 million pounds of thrust. The engines shut down and SpaceX began preparations to drain the Falcon 9 rocket of its super-chilled kerosene and liquid oxygen propellants.

SpaceX will lower the Falcon 9 at pad 39A and return it to a hangar at the southern perimeter of the seaside launch complex for attachment of a Crew Dragon spacecraft next week.

The Falcon 9 and Crew Dragon will roll back out to pad 39A, where teams will run through final launch preparations ahead of a planned liftoff next Saturday, Jan. 18, during a four-hour window opening at 8 a.m. EST (1300 GMT).

The high-altitude abort demonstration will be the final major test flight of the Crew Dragon spacecraft before it is cleared to fly astronauts. A two-man team of veteran NASA shuttle astronauts is assigned to the Crew Dragon's first piloted flight, designated Demo-2, later this year.

NASA astronauts Doug Hurley and Bob Behnken, who are assigned to the Demo-2 mission, are expected to participate in a countdown practice run at pad 39A next week with the Falcon 9 and Crew Dragon spacecraft.

The in-flight abort test itself next Saturday will be performed with no astronauts on-board the Crew Dragon.

The in-flight abort test will involve a full-up Crew Dragon spacecraft, with all its engines, computers and other key systems, launched atop a full-size Falcon 9 rocket from pad 39A at NASA's Kennedy Space Center in Florida.

SpaceX will launch the Falcon 9 rocket from pad 39A to simulate a crewed flight to the International Space Station, but the launcher's first stage engines will be programmed to shut down about a minute-and-a-half after liftoff as the launcher arcs toward the east from Florida's Space Coast.

The premature engine cutoff will be followed by an automated abort command on the Crew Dragon spacecraft, triggering ignition of the ship's eight SuperDraco escape thrusters.

The SuperDraco engines will rapidly power up to full throttle, producing up to 130,000 pounds of thrust for less than 10 seconds to push the Crew Dragon capsule away from the top of the Falcon 9 rocket.

The in-flight abort test is timed to demonstrate the capsule's escape system under the most extreme aerodynamic forces during launch.

Smaller thrusters will orient the crew capsule for separation of its unpressurized trunk, then deployment of parachutes before splashing down in the Atlantic Ocean east of Cape Canaveral.

The Falcon 9 booster is expected to break up due to extreme aerodynamic loads during the abort sequence. According to previously-released environmental review documents, the Falcon 9 will fly without a second stage engine on the in-flight abort test because the escape maneuver will occur during the first stage burn.

SpaceX performed a test of the Crew Dragon abort system in 2015 to simulate an escape maneuver from the launch pad, and then company completed a test-firing of the SuperDraco engines in November on the Crew Dragon vehicle set to fly on the high-altitude escape test.

The SuperDraco hotfire test verified the effectiveness of SpaceX's design changes in the Crew Dragon propulsion system after a previous capsule exploded during a similar ground firing earlier last year.

SpaceX, NASA Gear up for In-Flight Abort Demonstration

The uncrewed in-flight abort demonstration is targeted for 8 a.m. EST Saturday, Jan. 18, from Launch Complex 39A in Florida. There is a four-hour test window.

NASA and SpaceX are preparing to launch the final, major test before astronauts fly aboard the Crew Dragon spacecraft and Falcon 9 rocket to the International Space Station (https://www.nasa.gov/mission_pages/station/main/index.html) as part of the agency's Commercial Crew Program (https://www.nasa.gov/exploration/commercial/crew/index.html). The test, known as in-flight abort, will demonstrate the spacecraft's escape capabilities — showing that the crew system can protect astronauts even in the unlikely event of an emergency during launch. The uncrewed flight test is targeted for 8 a.m. EST Saturday, Jan. 18, at the start of a four-hour test window, from Launch Complex 39A in Florida.

SpaceX performed a full-duration static test Saturday, Jan. 11, of the Falcon 9 and completed a static fire of the Crew Dragon on Nov. 13, setting the stage for the critical flight test.

Prior to launch, SpaceX and NASA teams will practice launch day end-to-end operations with NASA astronauts, including final spacecraft inspections and side hatch closeout. Additionally, SpaceX and NASA flight controllers along with support teams will be staged as they will for future Crew Dragon missions, helping the integrated launch team gain additional experience beyond existing simulations and training events.

After liftoff, Falcon 9's ascent will follow a trajectory that will mimic a Crew Dragon mission to the International Space Station matching the physical environments the rocket and spacecraft will encounter during a normal ascent.

For this test, SpaceX will configure Crew Dragon to intentionally trigger a launch escape prior to 1 min, 30 seconds into flight to demonstrate Crew Dragon's capability to safely separate from the Falcon 9 rocket in the unlikely event of an in-flight emergency. Once the launch escape sequence begins, Falcon 9's first stage Merlin engines will shut down and Crew Dragon's SuperDraco thrusters will begin their firing sequence. The launch vehicle and spacecraft will separate, and Crew Dragon's SuperDracos will burn to completion.

After Crew Dragon's SuperDracos shutdown, the spacecraft will passively coast to apogee, the highest point in its arc. Near apogee, Crew Dragon's trunk will separate and the smaller Draco thrusters will re-orient the spacecraft for reentry and parachute deploy. At the appropriate conditions, Dragon's drogue and main parachutes will sequence to provide for a soft landing in the Atlantic Ocean near SpaceX Dragon recovery teams.

Following Crew Dragon's separation, Falcon 9 is expected to aerodynamically break up offshore over the Atlantic Ocean. Expected breakup time will vary based upon a number of factors, including day of launch winds and expected minor variations in vehicle attitudes and positions, but could occur shortly after separation or later upon reentry from the upper atmosphere. In either scenario, a dedicated team of SpaceX Falcon 9 recovery personnel will be staged and ready to begin recovering debris immediately after breakup.

As part of the Dragon recovery operation, Air Force Detachment-3 personnel will work with the SpaceX recovery team to observe Crew Dragon and practice their initial approach to the spacecraft in the open ocean, mimicking an actual rescue operation before the SpaceX team recovers Crew Dragon for return to Cape Canaveral.

SpaceX's uncrewed in-flight abort demonstration test of Crew Dragon's launch escape capabilities is designed to provide valuable data toward NASA certifying SpaceX's crew transportation system for carrying astronauts to and from the International Space Station.

NASA had similar "visibility launch commit criteria" for Orion's Ascent Abort back in July. These stricter-than-normal visibility rules are so all ground-based tracking assets can see the abort, track the vehicle thereafter, & gather good visual data on abort test sequence. 2/2

ЦитироватьSpaceX's brisk Starlink launch cadence to continue next week
January 14, 2020 (https://spaceflightnow.com/2020/01/) | Stephen Clark (https://spaceflightnow.com/author/stephen-clark/)

SpaceX plans to launch its next group of Starlink broadband satellites aboard a Falcon 9 rocket as soon as Monday, Jan. 20, from Cape Canaveral, two days after the company is scheduled to launch a modified Falcon 9 booster from a separate facility at the Florida spaceport to test the Crew Dragon spaceship's emergency escape system.

SpaceX's ability to achieve back-to-back launch schedule hinges on several factors, including an expected test-firing in the coming days of the Falcon 9 booster slated to fly on the next Starlink launch.

But assuming everything goes according to plan, SpaceX aims to perform launches from two pads on Florida's Space Coast as soon as Saturday and Monday.

SpaceX has already test-fired the Falcon 9 booster assigned to the Crew Dragon capsule abort test at launch pad 39A at NASA's Kennedy Space Center.

Technicians inside a hangar near pad 39A are attaching the Crew Dragon spaceship to the Falcon 9 rocket this week, in advance of its return to the launch complex before a countdown rehearsal Friday, during which two NASA astronauts will practice launch day procedures before climbing aboard the next Crew Dragon spaceship for a flight to the International Space Station.

The Falcon 9 is scheduled to lift off from pad 39A — without astronauts on-board — during a four-hour window opening at 8 a.m. EST (1300 GMT) Saturday. About a minute-and-a-half after launch, the first stage's nine Merlin 1D engines will be programmed to switch off, and SuperDraco thrusters on the Crew Dragon capsule mounted atop the rocket will ignite to propel the human-rated ship away from the Falcon 9.

The maneuver will demonstrate the Crew Dragon's ability to carry astronauts away from a launch emergency, and builds on a pad abort test in 2015 to simulate the Crew Dragon's abort system performance during an emergency before liftoff.

SpaceX will recover the Crew Dragon capsule from the Atlantic Ocean after it splashes down under parachutes around 20 miles (32 kilometers) offshore. The Falcon 9 rocket, flying with a previously-used first stage booster, is expected to be destroyed.

Meanwhile, teams at pad 40 at Cape Canaveral Air Force Station — located a few miles to the south of pad 39A — are preparing a separate Falcon 9 rocket for liftoff as soon as Monday, Jan. 20, sources said.

The Jan. 20 launch will haul the next batch of approximately 60 Starlink satellites into orbit for SpaceX's global broadband Internet network. Assuming the mission remains on schedule, liftoff time Jan. 20 is expected at 12:20 p.m. EST (1720 GMT).

The two upcoming launches from Florida's Space Coast will mark the second and third missions of the year for SpaceX, which says it could perform 35 or more launches in 2020, including flights carrying new Starlink broadband satellite into orbit as often as every two weeks.

SpaceX conducted 21 launches in 2018, the most missions in a single year in the company's history. The company launched 13 missions last year.

The first official weather forecast from the U.S. Space Force's 45th Weather Squadron predicts a 90 percent probability of acceptable conditions for liftoff of SpaceX's Falcon 9 rocket and Crew Dragon capsule from Florida's Space Coast Saturday.

The modified Falcon 9 launcher will take off from pad 39A at the Kennedy Space Center during a four-hour window opening at 8 a.m. EST (1300 GMT) Saturday.

A SpaceX Crew Dragon spacecraft on top of the Falcon 9 rocket will intentionally propel itself off the top of the launch vehicle around a minute-and-a-half after liftoff, simulating an in-flight escape maneuver. The abort system test is a prerequisite for the Crew Dragon's first mission with astronauts, a mission expected to lift off some time in the next few months.

Increasing clouds are expected Friday as a frontal boundary stalls south of Central Florida, according to the Space Force weather team stationed at Patrick Air Force Base.

"Winds will become southeasterly on Saturday, forming some shallow coastal showers," the weather team wrote in a forecast issued Wednesday. "The primary weather concern is flight through precipitation with those showers. Maximum winds through 40,000 feet will be from the west at 55 knots near 40,000 feet."

Winds at pad 39A's 200-foot-level will be from the southeast at 17 to 22 mph, with e temperature ranging between 66 degrees and 72 degrees Fahrenheit during Saturday's four-hour launch window.

Forecasters predict scattered clouds at 3,500 feet and a few clouds at 30,000 feet Saturday morning.

If the launch is delayed to Sunday or Monday, weather conditions are expected to worsen, with 60 to 70 percent probabilities of weather prohibiting liftoff of the Falcon 9 rocket.

A SpaceX Falcon 9 rocket and Crew Dragon capsule were raised vertical at launch pad 39A in Florida late Thursday, setting the stage for a launch day dress rehearsal Friday with NASA astronauts Doug Hurley and Bob Behnken — the veteran space fliers assigned to the Crew Dragon's first piloted mission later this year — before a critical in-flight test of the ship's emergency escape system Saturday.

NASA and SpaceX officials convened a launch readiness review Thursday and gave approval for SpaceX to proceed with final preparations for the Crew Dragon In-Flight Abort Test Saturday.

The test flight is se t for liftoff fr om pad 39A during a four-hour window Saturday opening at 8 a.m. EST (1300 GMT). There is a 90 percent chance of favorable weather for the test flight Saturday, according to the official launch weather forecast.

The launch escape demonstration will verify the SuperDraco abort engines on the Crew Dragon capsule can safely push the spacecraft away fr om a Falcon 9 rocket in flight. If the test goes well, the abort demonstration will be the final planned test flight for SpaceX's Crew Dragon program — managed under contract with NASA's commercial crew program — before astronauts Doug Hurley and Bob Behnken are cleared to fly the next Crew Dragon mission to the International Space Station.

Hurley and Behnken, both veterans of multiple space shuttle missions, are expected to put on their SpaceX-designed spacesuits early Friday to go through the procedures they will execute on launch day.

The two veteran NASA astronauts will not actually board the Crew Dragon spacecraft, but will practice their suit-up activities inside the Neil Armstrong Operations and Checkout Building at the Kennedy Space Center, the same facility wh ere Apollo and space shuttle crews prepared for launch.

SpaceX's spacesuits are fabricated in the company's factory in Hawthorne, California. Made of a single garment, with built-in gloves and boots, the pressure suits have a black and white motif, matching the colors of the Falcon 9 rocket and the launch tower and crew access arm at pad 39A.

Once in their launch and entry space suits, Behnken and Hurley are expected to travel to pad 39A from Kennedy's Operations and Checkout Building. The crew will take the same 8-mile (13-kilometer) trip by road on launch day.

Ground teams will also perform final inspections on the Crew Dragon capsule and close the ship's side hatch as they will before a crewed mission, according to NASA.

"Additionally, SpaceX and NASA flight controllers along with support teams will be staged as they will for future Crew Dragon missions, helping the integrated launch team gain additional experience beyond existing simulations and training events," NASA said in a statement.

The crew access arm will back away from the Crew Dragon spacecraft in the final hour of the countdown, and the spaceship's abort engines will be armed for flight.

The modified Falcon 9 rocket and Crew Dragon vehicle rolled out of SpaceX's hangar and up the ramp to pad 39A Thursday. After completing the quarter-mile trip on SpaceX's transporter-erector, the rocket was raised vertical at the launch pad shortly before 11 p.m. EST Thursday (0400 GMT Friday).

The Falcon 9 rocket will fire off pad 39A Saturday with 1.7 million pounds of thrust from its nine Merlin 1D engines, following a standard launch trajectory to mimic a crew flight to the space station.

Arcing toward the east over the Atlantic Ocean, the Falcon 9 will accelerate the Crew Dragon faster than the speed of sound before reaching a predetermined supersonic velocity threshold. Once the Falcon 9 hits that velocity — expected around 84 seconds after liftoff — the rocket will shut down its nine main engines to simulate a launch failure.

Then eight SuperDraco thrusters fixed to the circumference of the Crew Dragon spacecraft will ignite to quickly propel the spaceship away from the top of the Falcon 9 at an altitude of more than 60,000 (about 19 kilometers).

The SuperDraco engines, burning a high-pressure mix of hydrazine and nitrogen tetroxide propellants, will fire for less than 10 seconds to push the capsule away from its crippled booster.

Engineers expect the Falcon 9 itself, which is powered by a reused first stage booster, to break apart from aerodynamic forces after the Crew Dragon's escape maneuver, either immediately after the abort command or during its uncontrolled descent back through the atmosphere.

The SuperDraco engines would be used on a piloted flight to save astronauts from a catastrophic launch failure.

Launch abort systems have been used during emergencies on other rockets, most recently in October 2018, when a Russian Soyuz booster failed two minutes after liftoff. The Soyuz abort rockets fired to safely carry Russian cosmonaut Alexey Ovchinin and NASA flight engineer Nick Hague away from the Soyuz booster as it tumbled out of control.

After shutting down the SuperDraco engines, smaller Draco thrusters on the Crew Dragon will re-orient the craft for descent. The capsule will coast to an apogee of about 138,000 feet (42 kilometers), then jettison its no-longer-needed trunk section. The capsule will deploy parachutes to slow for splashdown in the Atlantic Ocean around 20 miles (32 kilometers) east of the Florida coast, wh ere teams from SpaceX and the U.S. Air Force will practice search-and-rescue techniques before retrieving the Crew Dragon for return to port.

Personnel with the Air Force's Detachment 3, part of the 45th Space Wing at Patrick Air Force Base, will work with SpaceX's recovery team downrange in the Atlantic Ocean to observe the Crew Dragon's splashdown. The military rescue team, working in coordination with SpaceX recovery vessels, will practice their approach to the spacecraft in the ocean, rehearsing a real-life astronaut rescue operation.

SpaceX teams will eventually pull the capsule from the sea and return it to port for inspections.

The Detachment 3 teams from Patrick Air Force Base include an HC-130 transport and refueling plane, and two HH-60 Pave Hawk helicopters with search and rescue teams on-board, according to NASA officials.

The military pararescue specialists will parachute from the aircraft into the Atlantic with inflatable boats.

SpaceX and Boeing, NASA's other commercial crew contractor, are responsible for recovering their spacecraft after a normal landing. The Crew Dragon splashes down at sea, with a primary zone in the Atlantic Ocean east of Florida and a backup zone in the Gulf of Mexico, and Boeng's Starliner capsule returns to a touchdown on land at one of several possible sites in the Western United States.

But like SpaceX's vehicle, the Boeing Starliner is designed for a water landing in case of a launch abort.

"We requested from (the military), if something goes awry, such as a pad abort or an ascent abort — which is what we're talking about with this In-Flight Abort Test — then they typically would go out and deploy their teams and provide for rescuing the crew, picking them up," said Ted Mosteller, NASA's commercial crew launch and landing lead, in an interview with CBS News.

"SpaceX, they're really specifically for the nominal landing site and nominal landing in most cases," he told CBS News. "And then the DoD, specifically Detachment Three down at Patrick, coordinates with the Air Force the assets that we use for rescue."

For a crewed mission, the search and rescue team at Patrick Air Force Base will have primary responsibility for retrieving the astronauts from the Crew Dragon spacecraft after a pad abort or launch emergency in the first few minutes of the flight, a scenario that would lead to a splashdown within about a 230-mile (370-kilometer) radius from Cape Canaveral.

Launch trajectories toward the space station head to the northeast from the Kennedy Space Center, following a path roughly parallel to the U.S. East Coast. NASA required SpaceX and Boeing, which launches its Starliner capsule on United Launch Alliance Atlas 5 rockets, to design their crew capsules to avoid splashing down in the middle of the North Atlantic Ocean in the event of an in-flight abort late in the ascent sequence.

If required, thrusters on the Crew Dragon or Starliner spacecraft would fire after an abort to ensure the capsule lands within about 300 miles of eastern Canada or Ireland, NASA officials told CBS News.

"Once you detach from a failing rocket, you will either have enough propellant to slow down and land before you get there, or to boost you to the other side of that zone," said Steve Payne, NASA's launch integration manager for the commercial crew program.

NASA and contractor teams will also assess sea states in the Atlantic Ocean before giving final approval for a crew launch.

On future commercial crew flights with astronauts on-board, a C-17 cargo plane from Charleston Air Force Base in South Carolina will be on standby to respond for a sea rescue farther away from the launch site in Florida. A C-17 aircraft with a similar search and rescue team would deploy from Hickam Air Force Base, Hawaii, for an emergency landing in the Pacific Ocean or neighboring seas.

During a crew launch, the rescue teams at Patrick Air Force Base could be airborne in 10 or 15 minutes, Mosteller told CBS News, and will aim to retrieve the astronauts and transport them to a local hospital within six hours. The C-17s are on a one-hour alert from the time of a SpaceX or Boeing crew launch until docking with the space station, with a goal of getting to the astronauts within 24 hours after an emergency landing anywhere in the world.

Mosteller told CBS News that the SpaceX and Boeing crew capsules both carry radio beacons to help the military search and rescue team locate the spacecraft. The Crew Dragon and Starliner both have flashing lights, and crews will carry handheld radios and personal locator beacons to communicate with search and rescue teams if the astronauts have to leave the spacecraft after splashdown.

The SpaceX and Boeing crew capsules both have a raft on-board, plus a survival kit with medications, food and fresh water, signaling mirrors, blankets and other equipment, Mosteller told CBS News.

Military rescue teams are also equipped with a larger life raft that can accommodate the search and rescue forces, along with the astronaut crews, and carries provisions for up to three days.

The pararescue specialists, also known as "Guardian Angels," jumped from military aircraft and simulated a rescue operation to demonstrate their ability to safely remove crew from the SpaceX Crew Dragon in the unlikely event of an emergency landing.

SpaceX developed the Crew Dragon under a $2.6 billion contract with NASA signed in 2014. NASA also awarded a contract to Boeing, which is also awaiting its first crewed mission — giving the agency two vehicles to help end U.S. reliance on Russian Soyuz spacecraft for crew transportation to the station.

SpaceX conducted the first Crew Dragon test flight to the space station last March, but engineers ran into trouble in April, when the capsule exploded during a ground test. The accident occurred moments before a ground test-firing of the Crew Dragon's SuperDraco abort engines and resulted in no injuries, but it destroyed the spaceship that just returned from the space station.

Engineers say they resolved the problem that led to the explosion, and SpaceX performed a similar ground firing of the SuperDraco engines on a new Crew Dragon vehicle in November, paving the way for the In-Flight Abort Test.

Assuming the launch escape test goes well Saturday, SpaceX could be on pace to launch astronauts Hurley and Behnken on the next Crew Dragon test flight in the next few months. That mission, designated Demo-2, is a precursor to the start of SpaceX's operational crew rotation service, with missions ferrying up to four astronauts to and from the space station for stays of up to 210 days.

• Kathy Lueders, manager, NASA Commercial Crew Program
  
• Benji Reed, director Crew Mission Management, SpaceX
  
• Mike McAleenan, launch weather officer, 45th Space Wing
  

Meteorologists with the U.S. Air Force 45th Space Wing predict a 90% chance of favorable weather for tomorrow's in-flight abort test. The primary concerns for launch day are the flight through precipitation rule during Saturday's four-hour launch window, which opens at 8 a.m. EST.

The flight test is planned to demonstrate Crew Dragon's ability to safely escape the Falcon 9 rocket in the event of a failure during launch.

Per the AFTS, because the engines are shutting down (thrust termination), the AFTS is not expected to blow the F9.  And Benji believes that would be true of a regular F9 if it encountered an engine shutdown failure in flight.

Испытание системы спасения экипажа Crew Dragon пройдет на мысе Канаверал
Как сообщили в компании SpaceX, в ходе испытаний будет использована ракета Falcon 9, полностью заправленная топливом

НЬЮ-ЙОРК, 17 января. /ТАСС/. Национальное управление по аэронавтике и исследованию космического пространства (NASA) и компания SpaceX проведут проверку работы системы спасения корабля Crew Dragon в субботу на космодроме на мысе Канаверал. Как сообщил на состоявшемся в пятницу брифинге в Центре космических полетов имени Кеннеди руководитель программы коммерческих полетов кораблей Crew Dragon Бенджи Рид, для эксперимента будет использована капсула корабля, ранее совершавшая полеты в космос.

В ходе испытаний, запланированных на 08:00 утра в субботу (16:00 мск) будет использована ракета Falcon 9, полностью заправленная топливом, сообщил представитель компании. Через 1 минуту 24 секунды после старта, когда ракета будет примерно на высоте 20 км, должна сработать система спасения: капсула корабля будет отстрелена в сторону от ракеты-носителя. Как ожидается, в этот момент в капсуле, где в пилотских ложементах будут находиться два манекена, оснащенные датчиками, возникнет четырехкратная перегрузка. Затем на корабле сработает система раскрытия парашютов и примерно через 10 минут после начала испытаний корабль осуществит приводнение в Атлантическом океане примерно в 30-35 км от побережья Флориды.

Сразу после отстрела капсулы двигатели ракеты-носителя будут отключены, она начнет снижение, и в какой-то момент начнется разрушение корпуса. Представитель SpaceX подчеркнул, что подрыва ракеты не будет, но не исключил возможности того, что в момент разрушения корпуса может произойти возгорание части топлива. Он подчеркнул, что поисково-спасательные группы попытаются собрать как можно больше обломков ракеты-носителя.

Crew Dragon - модификация грузового корабля Dragon, который уже доставляет грузы для МКС.

Помимо SpaceX, свой корабль - CST-100 Starliner - разработала корпорация Boeing. Он был впервые запущен 20 декабря в беспилотном режиме к МКС с авиабазы на мысе Канаверал в штате Флорида с помощью ракеты-носителя Atlas V. Стыковка со станцией планировалась на 22 декабря, однако в ходе полета возникла нештатная ситуация, вызванная сбоем в системе подсчета полетного времени. В итоге корабль было решено вернуть на Землю, исключив стыковку с МКС.

НАСА прекратило пилотируемые полеты в 2011 году после завершения программы использования возвращаемых кораблей Space Shuttle. С тех пор астронавты доставляются на МКС российскими "Союзами".

Hello Bouy 41009 of the National Bouy Center. As of this last hour, wind speeds of 21.4 km gusting to 27.2 km have occurred. This results in 8.5 ft waves with a wave period of 9 seconds. This may be great for surfing but not so much for recovering a Crew Dragon capsule.

ЦитироватьИспытание системы спасения корабля Crew Dragon отложили на сутки
14:00 18.01.2020

МОСКВА, 18 янв - РИА Новости. Испытание системы эвакуации новейшего пилотируемого корабля Crew Dragon на случай аварийного старта отложено на сутки из-за погодных условий, сообщила компания SpaceX.
"Испытание системы спасения корабля Crew Dragon отложено из-за сильного ветра и сильного волнения океана в зоне посадки", - сообщила компания на своей странице в Twitter (https://twitter.com/spacex).

Следующая попытка старта корабля с космодрома на мысе Канаверал намечена на воскресенье, 19 января, в 08.00 по времени Восточного побережья США (16.00 мск).

Испытание системы спасения, которая позволяет вернуть экипаж на Землю в случае аварии, является одним из ключевых этапов для допуска нового аппарата к пилотируемому запуску. Ранее в декабре систему эвакуации своего корабля Starliner успешно испытала компания Boeing. Она наряду со SpaceX создает пилотируемый корабль по заказу НАСА.

По замыслу организаторов тестового полета, система эвакуации будет активирована до окончания 1,5 минуты полета ракеты-носителя, двигатели которой будут заглушены для имитации аварийного старта. После этого должны включиться двигатели пилотируемой капсулы, чтобы отвести ее на безопасное расстояние от "аварийной ракеты". Их импульс позволит капсуле подняться на высоту порядка 42 километров, после чего будет сброшен грузовой отсек корабля, а капсула, где в будущем будут находиться пилоты, вернется на Землю. Посадка корабля ожидается в Атлантическом океане в 32 километрах от побережья Флориды приблизительно через 10 минут после старта.

В ходе предстоящего испытания, как сообщило НАСА, помимо технической готовности системы спасения корабля к пилотируемым стартам, планируется отработать технику поиска, спасения и возвращения на Землю экипажа на случай его аварийного возвращения. Содействие в этом традиционно будут оказывать специалисты военной авиации США.

Как отмечает в связи с предстоящим тестом портал Space Flight Now, в случае успеха, первый тестовый пилотируемый полет будет возможен через несколько месяцев. Планируется, что в рамках первого демонстрационного полета астронавты НАСА Даг Харли и Боб Бенкен совершат на борту Crew Dragon полет на МКС и обратно.

Первый испытательный полет корабля Crew Dragon состоялся в марте. Миссия прошла успешно: корабль успешно стартовал на ракете Falcon 9, пристыковался к МКС, провел на ней неделю и успешно вернулся на Землю. Испытание системы эвакуации должно было состояться вскоре после тестового полета, но в апреле в ходе наземного огневого испытания задействованных в системе спасения двигателей SuperDraco, произошел взрыв. Инцидент обошелся компании не только потерей новейшего корабля, но и еще более усугубил отставание в заявленном ранее графике начала пилотируемых стартов. Ранее США рассчитывали приступить к выполнению самостоятельных пилотируемых полетов до конца 2019 года, сейчас очевидно, что это вряд ли будет возможно до второй половины 2020 года, зависимость США от России в доставке астронавтов на МКС по крайней мере до конца 2020 года сохранится.

NASA and SpaceX teams are now planning to target Sunday, Jan. 19 for the company's in-flight abort test. The test window opens at 8 a.m. EST. Illustration credit: SpaceX

NASA and SpaceX now are targeting 8 a.m. EST Sunday, Jan. 19, for launch of the company's In-Flight Abort Test from Launch Complex 39A in Florida, which will demonstrate Crew Dragon's ability to safely escape the Falcon 9 rocket in the event of a failure during launch. The abort test has a six-hour launch window.

Teams are standing down from today's launch attempt due to poor splashdown and recovery weather.

For tomorrow's launch attempt, meteorologists with the U.S. Air Force 45th Space Wing predict a 60% chance of favorable weather toward the opening of the window with a 40% chance toward the end of the window. The primary concerns for launch day being the thick cloud layer and flight through precipitation rule during the launch window.

The test launch will air on NASA Television and the agency's website (http://www.nasa.gov/live). Here's the upcoming mission coverage:

Sunday, Jan. 19

January 18, 2020 (https://spaceflightnow.com/2020/01/) | Stephen Clark (https://spaceflightnow.com/author/stephen-clark/)

Illustration of the SpaceX Crew Dragon and Falcon 9 rocket during the company's uncrewed In-Flight Abort Test for NASA's Commercial Crew Program. This demonstration test of Crew Dragon's launch escape capabilities is designed to provide valuable data toward NASA certifying SpaceX's crew transportation system for carrying astronauts to and fr om the International Space Station.

SpaceX will sacrifice a Falcon 9 rocket Sunday in a fiery test a minute-and-a-half after liftoff fr om Florida's Space Coast to prove the company's Crew Dragon spacecraft can safely push astronauts away fr om a failing launch vehicle, simulating a daring maneuver that would only be attempted on a piloted mission during an in-flight emergency.

The launch escape demonstration could be a spectacle for local residents, rocket fans and enthusiasts along the Space Coast, assuming clear skies and good visibility, according to SpaceX.

While the Crew Dragon capsule — flying without astronauts on Sunday's test — fires away fr om the top of the Falcon 9 rocket, the booster itself is expected to tumble and break apart, possibly in a fireball visible from the ground.

The purpose of the test — the final planned demonstration of a full-scale Crew Dragon before NASA astronauts fly it int orbit — is to validate the ship's launch escape system. Abort rockets mounted around the circumference of the capsule would activate to rapidly carry the spaceship and its astronaut crew away from an emergency during launch on a Falcon 9 rocket, such as a booster failure or explosion.

"On launch day (with crews), we're really hoping for it not to be exciting," said Kathy Lueders, manager of NASA's commercial crew program. "I will tell you (Sunday) will be an exciting day. We are purposely failing a launch vehicle to make sure that our abort system on the spacecraft that we'll be flying for our crews works."

The Crew Dragon's eight liquid-fueled SuperDraco escape engines will ignite around 84 seconds after liftoff on top of a Falcon 9 rocket from pad 39A, soon after the point in the launch sequence wh ere the booster and capsule experience the most extreme aerodynamic pressures.

The abort thrusters will generate nearly 130,000 pounds of thrust, pushing the gumdrop-shaped crew capsule away from the top of the Falcon 9 with an acceleration of up to to 4Gs.

The six-hour test window opens at 8 a.m. EST (1300 GMT) Sunday. SpaceX called off a launch attempt early Saturday due to concerns about rough seas in the Atlantic Ocean east of Florida, wh ere the Crew Dragon splash down under parachutes around 10 minutes after launch from pad 39A the Kennedy Space Center.

"What will happen, basically, is we'll initiate launch escape, and the Falcon engines will shut down," said Benji Reed, SpaceX's director of crew mission management. "So the thrust of the Falcon will shut down right after that happens."

The abort burn should happen as the Falcon 9 and Crew Dragon are flying at an altitude of roughly 62,000 feet (19 kilometers) and traveling nearly twice the speed of sound.

"Dragon, at the same time, will be getting away," Reed said. "It takes about 10 seconds for a SuperDraco burn on the Dragon. Dragon will hit about Mach 2.3 as its getting away. We expect it to be actually quite far away from falcon at the acceleration its going before anything starts to happen on Falcon ... That's a very quick process."

The sudden separation of the Dragon spacecraft from top of the rocket, coupled with the loss of thrust from the Falcon 9's Merlin main engines, will likely cause the launcher to begin tumbling in the upper atmosphere.

"The Dragon will have left, so the top end of the second stage is now basically a big air scoop, so you've got all this air pushing against it, huge amounts of force pushing against it, and it's also cut thrust, so its no longer pushing up in a trajectory," Reed said. "It's going to be a lot more susceptible to the winds and starting to fall as it loses its velocity and starts to tumble.

"At some point, we expect that the Falcon will start to break up," Reed said. "Both stages are loaded with fuel because we want have the right mass, and test the right (way), so with those both stages loaded with fuel, we do expect there will probably be some amount of ignition, flame. We'll see something. On a clear day, possibly from the ground you could see it."

The first stage of the Falcon 9 rocket launching the Crew Dragon on Sunday's abort test is designated B1046. It's set to fly for the fourth and final time, and was the first upgraded Falcon 9 "Block 5" booster to launch in May 2018.

The Block 5 is the most recent, human-rated variant of SpaceX's Falcon 9 rocket.

Before the Crew Dragon abort test, the B1046 booster launched the Bangabandhu 1 communications satellite for Bangladesh from the Kennedy Space Center in May 2018, then launched again in August 2018 with the Indonesian Merah Putih communications spacecraft. The booster's third mission occurred in December 2018 from Vandenberg Air Force Base in California on a rideshare mission with 64 small satellites.

The booster landed on a SpaceX drone ship after each of its previous missions, but will not be recovered intact after the Crew Dragon abort test. SpaceX says teams will be stationed in the Atlantic Ocean just east of Cape Canaveral to pick up any floating debris from the rocket.

There is no second stage engine on the Falcon 9 rocket that will launch the abort test.

"The second stage will be loaded with propellant," Reed said. "There will still be quite bit of propellant in the first stage. We expect there to be some sort of ignition and probably a fireball of some kind.

"Whether I would call it an explosion that you would see from the ground, I don't know," he added. "We'll have to see what actually happens, but I wouldn't be surprised, and it wouldn't be a bad outcome."

In the unlikely event of a rocket mishap before the planned time of the Crew Dragon abort burn, the capsule will be armed to trigger a premature escape burn Sunday, according to Reed.

While the Falcon 9 booster's demise could prove a spectacle, SpaceX's attention will be on the performance of the crew capsule.

The in-flight launch abort capability is a crucial part of the Crew Dragon safety system. SpaceX verified the Crew Dragon's ability to escape an emergency on the launch pad in 2015 during a ground-launched pad abort test.

"(Sunday's) test is one of these things that's actually going to allow us test that whole system end-to-end," Reed said.

Meanwhile, the Crew Dragon will reach a top speed of Mach 2.3 and arc on a ballistic trajectory to a peak altitude of some 138,000 feet (42 kilometers), then use its thrusters to re-orient for descent. The capsule will jettison an unpressurized trunk section and deploy four main parachutes to gently splash down in the Atlantic Ocean around 20 miles (32 kilometers) offshore, wh ere U.S. military, NASA and SpaceX recovery teams will recover the capsule to practice procedures they would execute on a crew mission.

The entire abort test flight, from liftoff through splashdown, will take around 10 minutes.

SpaceX and NASA officials will have to carefully monitor weather and sea conditions for the in-flight abort test.

In addition the the typical launch weather constraints — such as high winds and lightning — engineers want good visibility to optically track the Falcon 9 launcher and Crew Dragon spacecraft during the escape sequence. And sea conditions in the Atlantic Ocean splashdown zone — roughly 20 miles (32 kilometers) east of pad 39A — are also important.

"It's a nice dance between launch weather, optics, and the winds and waves offshore, so we're trying to find a time wh ere all those things match up," said Mike McAleenan, the launch weather officer from the U.S. Space Force's 45th Weather Squadron. "But we'll find it, and we'll make sure we go when i'ts ready and everything is lining up."

Launch abort systems have been used during emergencies on other rockets, most recently in October 2018, when a Russian Soyuz booster failed two minutes after liftoff. The Soyuz abort rockets fired to safely carry Russian cosmonaut Alexey Ovchinin and NASA flight engineer Nick Hague away from the Soyuz booster as it tumbled out of control.

SpaceX is conducting the in-flight abort test under the terms of a commercial crew agreement awarded by NASA in 2012.

NASA has awarded SpaceX a series of funding agreements and SpaceX since 2011 worth more than $3.1 billion for development of a human-rated Dragon spacecraft. Boeing has received more than $4.8 billion from NASA since 2010 for its Starliner crew capsule.

Both companies aim to fly astronauts for the first time later this year, ending U.S. reliance on Russian Soyuz spacecraft for crew transportation to the International Space Station. NASA paid the Russian government $3.9 billion for crew transport services to the space station since the retirement of the space shuttle in 2011, according to the agency's inspector general.

A NASA official said Friday that SpaceX's next Crew Dragon spacecraft could be ready to launch astronauts Doug Hurley and Bob Behnken to the space station as soon as early March. But that schedule hinges on a good outcome to Sunday's abort test, the results of two more parachute drop tests, NASA data reviews and final assembly and processing milestones for the Crew Dragon spacecraft itself.

(https://img.novosti-kosmonavtiki.ru/130722.jpg)NASA and SpaceX now are targeting 10 a.m. EST for launch of the in-flight abort test.

NASA and SpaceX now are targeting 10 a.m. EST Sunday, Jan. 19, for launch of the company's In-Flight Abort Test from Launch Complex 39A in Florida, which will demonstrate Crew Dragon's ability to safely escape the Falcon 9 rocket in the event of a failure during launch. The abort test has a six-hour launch window ending at 2 p.m. this afternoon.

The test launch will air on NASA Television and the agency's website (http://www.nasa.gov/live). Here's the upcoming mission coverage:

Sunday, Jan. 19

[/li]
• 9:40 a.m. – NASA TV test coverage begins for the 10 a.m. liftoff
  
• 11:30 a.m. – Post-test news conference at Kennedy, with the following representatives:
  
• NASA Administrator Jim Bridenstine
  
• SpaceX representative
  
• Kathy Lueders, manager, NASA Commercial Crew Program
  
• Victor Glover, astronaut, NASA Commercial Crew Program
  
• Mike Hopkins, astronaut, NASA Commercial Crew Program
  

[/li][/LIST]
The time adjustment for today's launch attempt, splashdown and recovery of the Crew Dragon spacecraft allows for the best time to perform the abort demonstration based on weather conditions.

The U.S. Air Force 45th Space Wing continues to predict a 60% chance of favorable weather for launch toward the opening of the window with a 40% chance toward the end of the window. The primary concerns for launch day are the thick cloud layer and flight through precipitation rules during the launch window.

ЦитироватьSpaceX провела успешное испытание системы аварийного спасения космического корабля Crew Dragon
       Вашингтон. 19 января. ИНТЕРФАКС - Компания SpaceX в воскресенье в ходе запуска перспективного пилотируемого корабля многоразового использования Crew Dragon осуществила успешное испытание его системы аварийного спасения, сообщило NASA.
       Запуск с помощью ракеты-носителя Falcon 9 корабля был осуществлен в 10:30 по времени Восточного побережья США (18:30 мск) со стартового комплекса 39А на космодроме на мысе Канаверал (штат Флорида). Все испытание продолжалось около 10 минут. На борту Crew Dragon в качестве экипажа находились два манекена, оснащенные датчиками для слежения за их "самочувствием" в полете, в частности, во время четырехкратной перегрузки.
       В рамках отработки аварийной ситуации через полторы минуты после старта ракеты-носителя Falcon 9 на высоте около 22 км по команде с Земли от нее отстрелился корабль Crew Dragon. Восемь резервных двигателей SuperDraco корабля отвели его на безопасное расстояние от "аварийной" ракеты и подняли на высоту 42 км. Затем от корабля отсоединился грузовой отсек, и спускаемая капсула начала спуск для приводнения в Атлантике в 30-35 км от космодрома на мысе Канаверал. На спускаемой капсуле перед приводнением раскрылись все четыре парашюта. В район посадки направилось спасательное судно.
       Для испытания использовался корабль, который уже ранее побывал на орбите.
       В результате успешного испытания корабль Crew Dragon может быть сертифицирован NASA для проведения пилотируемых полетов к Международной космической станции (МКС).

Спойлер

      Таким образом, США спустя восемь лет после окончания программы полетов космических кораблей многоразового использования "Шаттл" в 2011 году вновь получат собственное транспортной средство для полетов астронавтов на орбиту. В настоящее время единственным средством доставки американских астронавтов на МКС являются российские корабли "Союз". Стоимость полета на "Союзе" для американских астронавтов составляет $82 млн.
       Как сообщалось, в начале марта прошлого года создаваемый SpaceX американский космический корабль многоразового использования Crew Dragon совершил успешный автономный полет к МКС. После отстыковки от станции спускаемая капсула доставила на Землю результаты научных экспериментов, проведенных экипажем станции.

Первый пилотируемый полет с экипажем в составе астронавтов-ветеранов Дуга Херли и Боба Бенкена, которые ранее летали на американских "Шаттлах", планируется осуществить уже весной нынешнего года. Корабль должен будет отправиться на МКС в двухнедельный полет.
       Принадлежащая Илону Маску компания SpaceX разрабатывает пилотируемый корабль в рамках контракта с НАСА на сумму $2,6 млрд.

SpaceX's Crew Dragon capsule has splashed down into the ocean! The test was completed in less than 10 minutes.

The next step is recovery of the spacecraft. That process is expected to take approximately two hours.

Stay tuned for a preview of the post-test news conference.

NASA and SpaceX successfully completed the in-flight abort test. The Crew Dragon spacecraft is now in the process of being recovered from the Atlantic Ocean. A post-test news conference is scheduled for today, no earlier than 11:30 EST.

The SpaceX Crew Dragon spacecraft splashed down offshore in the Atlantic Ocean at 10:39 a.m. EST after a launch on the company's Falcon 9 rocket from Launch Complex 39A at NASA's Kennedy Space Center in Florida.

Teams of personnel from SpaceX and the U.S. Air Force 45th Operations Groups Detachment-3 out of Patrick Air Force Base will recover the spacecraft for return to SpaceX facilities in Florida, and a dedicated team will begin the recovery effort of the Falcon 9, which broke apart as planned.

Next up on NASA television and the agency's website (http://www.nasa.gov/live):

Big bada boom, as expected — a crowd pleaser.  Once the crew capsule has safely ejected from the booster, the remains shred and go boom.  The capsule, off frame to the right, used its Draco thrusters to reorient and came in for a soft parachute landing at sea.

In terms of Demo-2 as long or short duration:  Jim: We have options given test today. DM2 crew would have to have additional training but having DM2 be long-duration would be good for US segment but not necessary. Decision NOT yet made. 1/3

But all options are on table.  Kathy notes that #NASA (https://twitter.com/hashtag/NASA?src=hash) has been working with SpaceX for last 6-7months to make sure the DM2 capsule can do a long duration mission.

И вообще, по расчетам ускорения хватило бы уйти даже если бы двигатель не выключились.
Но вообще выключение двигателей - это часть циклограмы срабатывания САС (ну если еще конечно есть чем эту команду отрабатывать).

ЦитироватьOn Sunday, January 19, SpaceX successfully completed an in-flight test of Crew Dragon's launch escape capabilities from Launch Complex 39A (LC-39A) at NASA's Kennedy Space Center in Florida. This test, which did not have NASA astronauts onboard the spacecraft, demonstrated Crew Dragon's ability to reliably carry crew to safety in the unlikely event of an emergency on ascent.

Falcon 9 and Dragon lifted off at 10:30 a.m. EST, or 15:30 UTC, with the abort sequence initiating approximately one and a half minutes into flight. Crew Dragon's eight SuperDraco engines powered the spacecraft away from Falcon 9 at speeds of over 400 mph. Following separation, Dragon's trunk was released and the spacecraft's parachutes were deployed, first the two drogue parachutes followed by the four upgraded Mark III parachutes. Dragon safely splashed down in the Atlantic Ocean and teams successfully recovered the spacecraft onto SpaceX's recovery vessel.

Updated 1:30 p.m. Eastern after post-test briefing.

WASHINGTON — SpaceX successfully tested the abort system of its Crew Dragon spacecraft Jan. 19, one of the final milestones before a crewed test flight that could take place as soon as this spring.

A Falcon 9 carrying the Crew Dragon spacecraft lifted off from Launch Complex 39A at the Kennedy Space Center at 10:30 a.m. Eastern, one day after poor weather postponed the previous launch attempt.

About 84 seconds after liftoff, the Crew Dragon ignited its eight SuperDraco thrusters, pulling the vehicle away from the Falcon 9. The spacecraft later jettisoned its trunk section and deployed parachutes, splashing down in the Atlantic Ocean about 32 kilometers offshore nearly nine minutes after liftoff.

While a detailed review of the data from the test will likely take weeks, both NASA and SpaceX leadership said the test appeared to go as expected. "Overall, as far as we can tell thus far, it is a picture-perfect mission. It went as well as one could possibly expect," said Elon Musk, chief executive of SpaceX, at a post-test briefing. He added he was "super fired-up" about the test.

"Another amazing milestone is complete for our very-soon-to-be project, which is launching American astronauts on American rockets from American soil," said NASA Administrator Jim Bridenstine at the briefing. "By all accounts this was a very successful test."

Bridenstine said that while this test was the "final major flight milestone" in the development of Crew Dragon, more work was still ahead, such as testing of the parachutes. Kathy Lueders, manager of the commercial crew program at NASA, said later that this flight served as the second "system-level" test of the spacecraft's upgraded parachutes, with two more such tests planned in the coming weeks.

At the briefing, Musk said that the Crew Dragon spacecraft that will fly the Demo-2 test flight, with NASA astronauts Bob Behnken and Doug Hurley on board, should be ready by the end of February. However, various reviews for the system, as well as ISS schedules, mean it will take some time even after the spacecraft is ready before the mission can launch.

"The collective wisdom at this point is that we're highly confident the hardware will be ready in [quarter] 1," Musk said. "It appears probable that the first crewed launch will occur in the second quarter."

The Falcon 9 rocket used for the test broke up and exploded several seconds after the Crew Dragon escape. That breakup and subsequent fireball was expected, as SpaceX officials said prior to the test that the first stage booster, making its fourth flight, would not survive the test.

"Fairly quickly, Falcon will be going through a lot of aerodynamic issues," said Benji Reed, director of crew mission management at SpaceX, during a pre-flight press conference Jan. 17. With the capsule no longer on top of the rocket, the top of the upper stage became "a big air scoop," he said. "At some point we expect the Falcon will start to break up" with some of the remaining fuel and oxidizer igniting.

Among those watching the test were NASA astronauts Victor Glover and Mike Hopkins, who will fly the first post-certification, or operational, Crew Dragon mission along with two international astronauts yet to be assigned.

"So far, what we've seen is what we expected," Glover said at the post-test briefing. This test, he and Hopkins noted, was particularly important for their families ahead of their flight on the spacecraft as soon as late this year.

"I did receive a text from my wife right afterwards," Hopkins said. "Everything looked good from her perspective."

NASA and SpaceX completed a launch escape demonstration of the company's Crew Dragon spacecraft and Falcon 9 rocket on Jan. 19, 2020. The test began at 10:30 a.m. EST with liftoff from Launch Complex 39A at NASA's Kennedy Space Center in Florida on a mission to show the spacecraft's capability to safely separate from the rocket in the unlikely event of an inflight emergency. Credits: NASA Television

NASA and SpaceX completed a launch escape demonstration of the company's Crew Dragon spacecraft and Falcon 9 rocket Sunday. This was the final major flight test of the spacecraft before it begins carrying astronauts to the International Space Station under NASA's Commercial Crew Program (https://www.nasa.gov/commercialcrew).

The launch escape test began at 10:30 a.m. EST with liftoff from historic Launch Complex 39A at NASA's Kennedy Space Center (https://www.nasa.gov/centers/kennedy/home/index.html) in Florida on a mission to show the spacecraft's capability to safely separate from the rocket in the unlikely event of an inflight emergency.

"This critical flight test puts us on the cusp of returning the capability to launch astronauts in American spacecraft on American rockets from American soil," said NASA Administrator Jim Bridenstine. "We are thrilled with the progress NASA's Commercial Crew Program is making and look forward to the next milestone for Crew Dragon."

As part of the test, SpaceX configured Crew Dragon to trigger a launch escape about 1.5 minutes after liftoff. All major functions were executed, including separation, engine firings, parachute deployment and landing. Crew Dragon splashed down at 10:38 a.m. just off the Florida coast in the Atlantic Ocean.

"As far as we can tell thus far, it's a picture perfect mission. It went as well as one can possibly expect," said Elon Musk, chief engineer at SpaceX. "This is a reflection of the dedication and hard work of the SpaceX and NASA teams to achieve this goal. Obviously, I'm super fired up. This is great."

Teams of personnel from SpaceX and the U.S. Air Force 45th Operations Group's Detachment-3 out of Patrick Air Force Base will recover the spacecraft for return to SpaceX facilities in Florida and begin the recovery effort of the Falcon 9, which broke apart as planned.

"The past few days have been an incredible experience for us," said astronaut Doug Hurley. "We started with a full dress rehearsal of what Bob and I will do for our mission. Today, we watched the demonstration of a system that we hope to never use, but can save lives if we ever do. It took a lot of work between NASA and SpaceX to get to this point, and we can't wait to take a ride to the space station soon."

Prior to the flight test, teams completed launch day procedures for the first crewed flight test, from suit-up to launch pad operations. The joint teams now will begin the full data reviews that need to be completed prior to NASA astronauts flying the system during SpaceX's Demo-2 mission.

NASA's Commercial Crew Program is working with the American aerospace industry as companies develop and operate a new generation of spacecraft and launch systems capable of carrying crews to low-Earth orbit and the International Space Station (http://www.nasa.gov/station). Commercial human space transportation to and from the station will provide expanded utility, additional research time and broader opportunities for discovery on the orbiting laboratory. The program also has the benefit of facilitating and promoting for America a vibrant economy in low-Earth orbit.

Илон Маск заявил о первом пилотируемом полете Crew Dragon во втором квартале 2020
Глава SpaceX уточнил, что необходимое для запуска пилотируемого Crew Dragon оборудование будет готово к концу февраля, но не позднее марта

НЬЮ-ЙОРК, 19 января. /ТАСС/. Первый пилотируемый полет космического корабля Crew Dragon американской компании SpaceX планируется на второй квартал текущего года. Об этом сообщил в воскресенье на пресс-конференции глава SpaceX Илон Маск, трансляция велась на сайте Национального управления США по аэронавтике и исследованию космического пространства (NASA).

Маску был задан вопрос, когда предполагается осуществить первый пилотируемый запуск Crew Dragon с учетом успешного испытания в воскресенье системы спасения этого нового космического корабля. Глава компании уточнил, что сроки такого пуска определялись совместно SpaceX и NASA. "Я полагаю, что необходимое для запуска пилотируемого Crew Dragon оборудование будет готово к завершению февраля, но не позднее марта", - сказал он, подчеркнув, что проверки всех систем и узлов оборудования будут проводиться по три-четыре и более раз.

"Представляется вероятным осуществить первый пилотируемый запуск во втором квартале", - добавил Маск.

SpaceX в воскресенье осуществила испытательный запуск ракеты-носителя Falcon 9 для проверки надежности работы системы спасения Crew Dragon. Испытания, начавшиеся пуском с космодрома на мысе Канаверал (штат Флорида), длились чуть более 10 минут. Капсула корабля была отстрелена в сторону от носителя, после чего Crew Dragon спустился на четырех парашютах и приводнился в Атлантическом океане.

Носитель в соответствии со сценарием испытаний сгорел.

В автоматическом режиме Crew Dragon был отправлен к станции 2 марта прошлого года и пристыковался к ней на следующий день. Сроки первого пилотируемого полета этого корабля несколько раз менялись.

NASA настроено наращивать присутствие на МКС и не откажется от "Союзов"
Ведомство заинтересовано в увеличении числа своих астронавтов на Международной космической станции

НЬЮ-ЙОРК, 19 января. /ТАСС/. Национальное управление США по аэронавтике и исследованию космического пространства (NASA) не отказывается от мест на российских кораблях "Союз", так как заинтересовано в увеличении числа своих астронавтов на Международной космической станции (МКС). Об этом заявил в воскресенье директор NASA Джим Брайденстайн на пресс-конференции, трансляция которой велась на сайте космического ведомства.

"Я хотел бы четко заявить, что NASA будет сохранять и впредь свое присутствие на околоземной орбите. Нам нужно еще многое усвоить там", - отметил директор NASA.

Ему был задан вопрос, позволяет ли успешное испытание космического корабля Crew Dragon компании SpaceX отказаться от доставки американских астронавтов на МКС российскими "Союзами". "Даже при той уверенности в нашей команде, которую мы испытываем, я думаю, что будет неразумно пойти таким путем. Я считаю важным наращивать спектр имеющихся у нас возможностей и обеспечивать дальнейшее американское присутствие на Международной космической станции. Мы не готовы делать какие-либо корректировки на этом фронте", - ответил Брайденстайн.

Он дал ясно понять, что NASA под его руководством заинтересовано в увеличении числа американских астронавтов, несущих вахту на МКС. "Будущему экипажу надо будет активизировать подготовку в расчете на, возможно, более длительное пребывание в космосе. Первый пилотируемый полет Crew Dragon также позволяет заняться дополнительной деятельностью, которая пока не запланирована, но может потребоваться в зависимости от происходящего на МКС. Лучше, чтобы на борту находилось больше человек для подобной деятельности, а не меньше", - резюмировал Брайденстайн.

NASA прекратило собственные пилотируемые полеты в 2011 году после завершения эксплуатации кораблей многоразового использования (программа Space Shuttle). С тех пор астронавтов доставляют на МКС российскими кораблями "Союз".

Сроки начала полетов новых американских космических кораблей Starliner корпорации Boeing и корабля Сrew Dragon корпорации SpaceX ранее неоднократно переносились. Согласно американскому порталу госзакупок, США планируют в 2020-2021 годах приобрести два места в российских "Союзах" для отправки астронавтов на МКС.

SpaceX's Falcon 9 booster disintegrated in a fireball — as expected — a few seconds after the Crew Dragon capsule fired away fr om the top of the rocket in an in-flight escape demonstration Sunday. Credit: Spaceflight Now

SpaceX performed a dramatic high-altitude test flight Sunday of the company's Crew Dragon capsule over Florida's Space Coast, testing the human-rated ship's ability to escape a rocket failure and save its crew before two NASA astronauts strap in for a flight to the International Space Station as soon as this spring.

The unusual test flight included an intentional failure of the Crew Dragon's Falcon 9 rocket about a minute-and-a-half after liftoff fr om the Kennedy Space Center. The rocket disintegrated in a fireball high over the Atlantic Ocean as the crew capsule sped away fr om the top of the launcher with a powerful boost from eight SuperDraco engines.

The SuperDraco engines — mounted around the circumference of the gumdrop-shaped crew capsule — fired around eight seconds to carry the spaceship a safe distance from the Falcon 9 rocket after the booster's first stage engines shut down, a standard part of the launch escape sequence.

The Crew Dragon arced on a ballistic trajectory to a top speed of about Mach 2.2 and a peak altitude of about 131,000 feet, according to Elon Musk, SpaceX's founder and chief executive. The capsule then deployed four main parachutes for a splashdown in the Atlantic Ocean roughly 20 miles (32 kilometers) east of the Kennedy Space Center.

"I'm super fired up," Musk said. "This is great ... We're looking forward to the next step."

NASA has signed agreements with SpaceX valued at more than $3.1 billion since 2011 to fund the design, development, construction and testing of the Crew Dragon spacecraft.

The next major step for the Crew Dragon program is the capsule's first trip to space with astronauts. The Crew Dragon's in-flight abort test Sunday was the last major flight demonstration of a full-scale Crew Dragon spacecraft before its first launch with humans on-board.
...

In the meantime, SpaceX will collect all the data from the Crew Dragon abort test and analyze the results for any potential problem areas. NASA is also reviewing numerous Crew Dragon data packages provided by SpaceX before agreeing to fly Hurley and Behnken on SpaceX's next crew capsule launch.

SpaceX plans at least two more atmospheric drop tests of the Crew Dragon parachute system to gain more confidence in the capsule's decelerators, which have been a problem area on the project after chute failures on a cargo-carrying Dragon spacecraft and in Crew Dragon testing.

Engineers found that NASA was using wrong assumptions in models that predict how much force parachutes experience on spacecraft returning to Earth. Data from testing showed the parachute risers, or suspension lines, encountered more significant loads than expected, raising concerns about chutes across the agency's human spaceflight programs, including on the Starliner commercial crew capsule being developed by Boeing.

SpaceX and NASA agreed to switch to a new generation of Crew Dragon parachutes dubbed the Mark 3, and testing of the new Mark 3 chutes — made by a company named Airborne Systems — has proceeded without failure since late last year.

Sunday's in-flight abort test provided the parachute engineers with another successful test of the Mark 3 chutes, adding additional confidence about the system's reliability.

NASA Administrator Jim Bridenstine called Sunday's abort test "another amazing milestone" in the agency's nearly decade-long effort to resume crew launches to the space station from U.S. soil.

"Make no mistake, there's a lot left to do," Bridenstine said. "We have a number of parachute tests upcoming, and of course, we're going to get a lot of data from this particular test. So we're not quite there yet, but by all accounts, this was a very successful test."

After a one-day delay due to rough seas in the splashdown zone — and a two-and-a-half-hour hold Sunday to wait for improved winds — the Crew Dragon spacecraft lifted off on top of a SpaceX Falcon 9 rocket at 10:30 a.m. EST (1530 GMT) Sunday from pad 39A at Kennedy, the same launch pad once used by NASA's Saturn 5 moon rockets and space shuttles.

The 215-foot-tall (65-meter) rocket flew off the launch pad powered by nine kerosene-fueled Merlin 1D engines and pitched on an easterly trajectory from the Florida spaceport.

The Falcon 9 surpassed the speed of sound in less than a minute, and the Crew Dragon's pre-programmed escape sequence initiated around 84 seconds after liftoff, when the rocket was at an altitude of roughly 62,000 feet (19 kilometers).

The abort was triggered soon after the point in the launch sequence wh ere the booster and capsule experience the most extreme aerodynamic pressures.

While the nine Merlin engines on the Falcon 9 rocket cut off in response to the escape command, nearly 130,000 pounds of thrust from the SuperDraco engines pushed the Crew Dragon rapidly away from the top of the launcher.

SpaceX said the capsule, and two mannequins seated inside, accelerated at about 3.5Gs during the abort, a relatively gentle ride for astronauts in good physical condition.

The Crew Dragon can initiate an abort and free itself of a failing launch vehicle in just 700 milliseconds, according to Musk.

"It's way more than a human could do," he said. "It's occurring in a fraction of a second. There's a command for the engines to shut down, and then the abort system then presses up very rapidly, the SuperDracoss are ignited to initiate separation from the upper stage. All of this is occurring in literally a split second, and it's really quite remarkable how quickly those engines reach full thrust."

The SuperDracos keep the Crew Dragon pointed in the right direction using differential thrust, Musk said.

"So it's making those thrust adjustments at the almost millisecond level," he said. "It's very, very fast."

This demonstration test of Crew Dragon's launch escape capabilities is designed to provide valuable data toward NASA certifying SpaceX's crew transportation system for carrying astronauts to and from the International Space Station.

Sunday's in-flight abort test builds on a Crew Dragon demonstration in 2015 that proved the craft's SuperDraco engines could safely boost itself away from the top of a rocket on the launch pad in the event of a preflight emergency.
...

Musk said the Crew Dragon's abort system, which is integrated on the crew module itself instead of using a top-mounted launch abort tower like the Apollo spacecraft or Russia's Soyuz capsule, comes with the benefit of enabling an abort maneuver from before the time of liftoff all the way through the Falcon 9's ascent to orbit.

"The fact that the launch abort system is integrated with the spacecraft, with the SuperDraco thrusters in the sidewall, means that you have launch abort capability all the way to orbit, whereas previously with launch escape tower — because that's top heavy — that is discarded 20 or 30 percent of the time into flight."

SpaceX designed the SuperDracos with another purpose in mind.
...
The escape engines appeared to perform well Sunday, along with other Crew Dragon systems, according to Musk.

While wreckage from the Falcon 9 booster fell to Earth at high speed, the Crew Dragon's parachutes slowed the capsule for an ocean landing. Winds in the splashdown area were near the lim it for a Crew Dragon return.

The winds at the splashdown zone were around 18 mph, or 16 knots, providing data on the performance of the parachutes under more stressing conditions than they might see on a typical return, Musk said.

U.S. military search and rescue teams deployed in the Atlantic Ocean practiced procedures to approach the capsule after splashdown. The teams from Patrick Air Force Base just south of Cape Canaveral would rescue astronauts from the spacecraft after a launch abort.

SpaceX's "Go Searcher" recovery ship hoisted the capsule from the sea and returned the Crew Dragon to Port Canaveral, wh ere teams will offload the ship to begin inspections and analysis.

Можно вместо 4-х парашютов брать один парашют (как у Союза), тогда проблемы нет по определению).
А можно 3 парашюта, как у Аполлона, но у Аполлона эти 3 парашюта расходятся на большой угол от вертикали. Почему Маск тоже не делает большой угол расхождения парашютов - не понятно.

January 23, 2020 (https://spaceflightnow.com/2020/01/) | Stephen Clark (https://spaceflightnow.com/author/stephen-clark/)

(https://img.novosti-kosmonavtiki.ru/145876.jpg)

Data from the Jan. 19 in-flight launch escape demonstration of SpaceX's Crew Dragon spacecraft indicate the performance of the capsule's SuperDraco abort engines was "flawless" as the thrusters boosted the ship away from the top of a Falcon 9 rocket with a peak acceleration of about 3.3Gs, officials said Thursday.

The Jan. 19 test demonstrated the Crew Dragon's ability to safely carry astronauts away from a launch emergency, such as a rocket failure, and return the crew to a parachute-assisted splashdown in the Atlantic Ocean.

For its final full-scale test before astronauts ride it into space, the Crew Dragon spacecraft lifted off at 10:30 a.m. EST (1530 GMT) on Jan. 19 from pad 39A at the Kennedy Space Center in Florida. A Falcon 9 rocket carried the capsule aloft — just as it would on a crewed mission — for the first 85 seconds of the mission.

The Crew Dragon began its launch escape maneuver at 10:31:25 a.m. EST (1531:25 GMT) — initiated by a low setting of an on-board acceleration trigger — when the Falcon 9 was traveling at a velocity around 1,200 mph (536 meters per second), according to SpaceX.

Eight SuperDraco thrusters immediately pressurized and ignited as the Falcon 9 rocket's first stage engines were commanded to shut down as part of the abort sequence.

The escape engines on the Crew Dragon produced nearly 130,000 pounds of thrust at full power. The SuperDracos performed flawlessly, SpaceX said, accelerating the capsule away from the top of the Falcon 9 at a peak acceleration of 3.3Gs.

The SuperDracos accelerated the spacecraft from about 1,200 mph up to more than 1,500 mph (about 675 meters per second) in approximately seven seconds, according to SpaceX.

While the Crew Dragon boosted itself away from the Falcon 9, the rest of the rocket was expected to break apart from aerodynamic forces. It did just that, disintegrating suddenly in a fireball as the crew capsule safely sped away.

Although the Falcon 9 erupted in a fireball seconds after the Crew Dragon escaped the rocket on the Jan. 19 abort test, the crew capsule is designed to get away from a rocket even if it explodes or breaks apart with little warning, according to Elon Musk, SpaceX's founder and CEO.

"In principle, the system is designed to withstand an adverse booster explosion ... that happens even before the escape event," Musk said at a press conference after Sunday's abort test. "So it's it's intended to be very robust, in principle. And ... it's less of an explosion than it is fire. It's a fireball, but it's more for a fireball than it is an over overpressure event like an explosion.

"And since the spacecraft has a very powerful base heat shed and even the leeward side heat shield, it should be really not significantly affected by a fireball," Musk said. "So it could quite literally — like something out of Star Wars — fly right out of the fireball. Obviously, we want to avoid doing that but. But it is really meant to be something that can fly out of the fireball."

Unlike other crew capsules, such as Russia's Soyuz spacecraft and NASA's Orion deep space exploration vehicle, the Falcon 9 and Crew Dragon do not have a large abort tower mounted to the top of the rocket. The Soyuz and Orion capsules use solid-fueled "tractor" abort systems that pull the spacecraft away from its launch vehicle in the event of a failure.

The Crew Dragon uses SuperDraco engines fed by hydrazine and nitrogen tetroxide propellants to push the capsule away from a failing rocket.

Musk said the Jan. 19 abort test appeared "picture-perfect" at first glance.

SpaceX said the telemetry signal from the Falcon 9 rocket halted around 11 seconds after the escape burn, suggesting a "comfortable" distance of about 4,900 feet (1.5 kilometers) between the Crew Dragon and the Falcon 9 fireball.

The Crew Dragon reached a top speed on the abort test of about Mach 2.3, and a maximum altitude of more than 131,000 feet (40 kilometers).

The capsule jettisoned its unpressurized trunk section, which fell to the Atlantic Ocean, before deploying parachutes to slow itself for splashdown.

The drogue chutes deployed at an altitude of about 19,000 feet (5.8 kilometers), and the Crew Dragon's four main chutes unfurled around 6,500 feet (2 kilometers) above the ocean.

The capsule splashed down in the Atlantic Ocean around 26 miles (42 kilometers) east of the launch site at 10:38:54 a.m. EST (1538:54 GMT), just under nine minutes after liftoff, according to data released by SpaceX.

Recovery teams picked up the capsule from the sea and hoisted it on the deck of SpaceX's Crew Dragon retrieval ship — named Go Searcher — for the trip back to Port Canaveral. The spaceship returned to port less than nine hours after launch, demonstrating SpaceX teams can quickly return the capsule to land after a splashdown close to shore.

With the Crew Dragon in-flight escape test complete, engineers will analyze additional data over the coming weeks to verify everything functioned as designed. Assuming no showstoppers, the abort demonstration was the final planned test flight of a full-scale Dragon capsule before NASA clears the commercial crew ferry ship to carry astronauts Doug Hurley and Bob Behnken to the International Space Station.

At least two more drop tests to test the Crew Dragon's parachutes are planned beginning in mid-February.

The parachutes and launch abort propulsion system have been the primary drivers of Crew Dragon schedule delays over the last year. SpaceX encountered chute failures during the capsule's development, and an explosion destroyed a Crew Dragon spacecraft during an attempted ground test-firing of its SuperDraco thrusters last year.

While data reviews are underway, NASA is evaluating whether to extend the duration of the Crew Dragon's first piloted test flight from a week-long mission to the space station to a longer stay that could have Hurley and Behnken live and work aboard the orbiting outpost for months.

Officials said they will factor in the astronauts' training schedules — which may be lengthened if they're approved for an extended stay at the space station — and the schedule of other crew rotation missions to the orbiting research lab before setting a target launch date for Hurley and Behnken.

NASA and SpaceX said after the Jan. 19 abort test that the first Crew Dragon launch with astronauts could occur in the second quarter of this year, between the beginning of April and the end of June.

SpaceX's Crew Dragon spacecraft and Boeing's Starliner crew capsule are in the final stages of testing before NASA approves the vehicles to carry astronauts. NASA has multibillion-dollar contracts with both companies to develop the human-rated spaceships.

Both capsules are designed to end NASA's sole reliance on Russian Soyuz spacecraft for crew rotation missions to the space station, an operating scheme NASA has been in since the retirement of the space shuttle in 2011.

Data from the Jan. 19 in-flight launch escape demonstration of SpaceX's Crew Dragon spacecraft indicate the performance of the capsule's SuperDraco abort engines was "  flawless  " as the thrusters boosted the ship away from the top of a Falcon 9 rocket with a peak acceleration of about   3.3Gs  , officials said Thursday.

On Sunday, January 19, SpaceX successfully completed an in-flight test of Crew Dragon's launch escape capabilities from Launch Complex 39A (LC-39A) at NASA's Kennedy Space Center in Florida. This test, which did not have NASA astronauts onboard the spacecraft, demonstrated Crew Dragon's ability to reliably carry crew to safety in the unlikely event of an emergency on ascent.

Falcon 9 and Dragon lifted off at 10:30 a.m. EST, or 15:30 UTC, with the abort sequence initiating approximately one and a half minutes into flight. Crew Dragon's eight SuperDraco engines powered the spacecraft away from Falcon 9 at speeds of over 400 mph. Following separation, Dragon's trunk was released and the spacecraft's parachutes were deployed, first the two drogue parachutes followed by the four upgraded Mark III parachutes. Dragon safely splashed down in the Atlantic Ocean and teams successfully recovered the spacecraft onto SpaceX's recovery vessel.
