NASA sets #SpaceX #DM1 launch for 7 Jan 2019 in what is LIKELY to be a NIGHT LAUNCH. Given what we know of Dragon/ISS phasing ability, launch should be roughly JUST BEFORE MIDNIGHT (i.e. 23:5x EST on 7 Jan) or 045x UTC on 8 Jan. Might surprise us, but this is what is looks like.

NASA's Commercial Crew Program Target Test Flight Dates

Marie Lewis
Posted Nov 21, 2018 at 10:00 am



The next generation of American spacecraft and rockets that will launch astronauts to the International Space Station are nearing the final stages of development and evaluation. NASA's Commercial Crew Program will return human spaceflight launches to U.S. soil, providing safe, reliable and cost-effective access to low-Earth orbit on systems that meet our safety and mission requirements.

To meet NASA's requirements, the commercial providers must demonstrate that their systems are ready to begin regular flights to the space station. Two of those demonstrations are uncrewed flight tests, known as Orbital Flight Test for Boeing, and Demo-1 for SpaceX. After the uncrewed flight tests, both companies will carry out spacecraft abort tests to demonstrate their crew escape capability during an actual on-pad, or ascent emergency. The final test flights for each company will be crew flight tests to the space station prior to being certified by NASA for crew rotation missions. The following target dates reflect the current schedule as of Tuesday, Nov. 20.

Test Flight Planning Dates:
Boeing Orbital Flight Test (uncrewed): March 2019
Boeing Pad Abort Test: Between OFT and CFT
Boeing Crew Flight Test (crewed): August 2019
SpaceX Demo-1 (uncrewed): January 7, 2019
SpaceX In-Flight Abort Test: Between Demo-1 and Demo-2
SpaceX Demo-2 (crewed): June 2019

SpaceX also completed a pad abort test in 2015. Following the test flights, NASA will review the performance data and resolve issues as necessary to certify the systems for operational missions.  Boeing, SpaceX and the Commercial Crew Program are actively working to be ready for the operational missions; however, as with all human spaceflight development, learning from each test and adjusting as necessary to reduce risk to the crew may override planning dates.

Anticipated Readiness Dates for Operational Missions:
First operational mission: August 2019
Second operational mission: December 2019

Draft Environmental Assessment for Issuing SpaceX a Launch License for an In-flight Dragon Abort Test, Kennedy Space Center, Brevard County, Florida

The abort test would start with a nominal launch countdown and release at T-0. The Falcon 9 with the Dragon attached would follow a standard ISS trajectory with the exception of launch azimuth to approximately Mach 1. The Falcon 9 would be configured to shut down and terminate thrust, targeting the abort test shutdown condition (simulating a loss of thrust scenario). Dragon would then autonomously detect and issue an abort command, which would initiate the nominal startup sequence of Dragon's SuperDraco engine system. Concurrently, Falcon 9 would receive a command from Dragon to terminate thrust on the nine first stage Merlin 1D (M1D) engines. Dragon would then separate from Falcon 9 at the interface between the trunk and the second stage, with a frangible nut system. Under these conditions, the Falcon 9 vehicle would become uncontrollable and would break apart. SpaceX would not attempt first stage booster flyback to KSC, CCAFS, or a droneship, nor would they attempt to fly the booster to orbit. 
...
Dragon would fly until SuperDraco burnout and then coast until reaching apogee, at which point the trunk would be jettisoned. Draco thrusters would be used to reorient Dragon to entry attitude. Dragon would descend back toward Earth and initiate the drogue parachute deployment sequence at approximately 6 miles altitude and main parachute deployment at approximately 1 mile altitude. Dragon recovery operations would be very similar to actions for normal Dragon reentry and recovery (USAF 2013), although Dragon recovery during the abort test would occur approximately 9–42 miles from shore
...
Dragon weighs approximately 17,000 pounds without cargo
...
The Dragon test vehicle is intended to represent the final flight configuration of Dragon-2. Systems, subsystems, and components critical to the success of in-flight abort would be in the final configuration. Non-critical systems would either be eliminated or simplified to reduce the complexity
of the ground refurbishment process to conduct the abort test. Dragon would contain approximately 5,650 pounds of hypergolic propellant, including approximately 3,500 pounds of dinitrogen tetroxide (NTO) and 2,150 pounds of monomethylhydrazine (MMH). Dragon would contain approximately 2,400 pounds of residual propellant after the abort test. 
...
A Falcon 9 (Block 5) first stage booster would be used for the abort test (Figure 2-2). The booster would be a standard Falcon 9 first stage and configured in an expendable configuration for the abort test. Landing legs and grid fins would be removed. No booster recovery burns would be attempted. As such, a full triethylaluminum-triethylborane (TEA-TEB) mixture used as a first and second stage ignitor would not be used. The booster would be capable of flying a mission profile that allows for the target abort velocity to be achieved.
...
The second stage would be a standard Falcon 9 second stage, with the exception of the M1D vacuum engine. The components essential to propellant loading operations would be carried, but the thrust chamber, turbopump, thrust vector control actuators, and other components required for performing second stage burns, would be omitted, as the mission concludes part-way through the first stage ascent burn. Propellant loading would follow standard loading operations for the second stage.

Dragon (both versions) is composed of two main elements: the capsule for pressurized crew and cargo and the unpressurized cargo module or "trunk" (see Exhibit 1). The capsule contains a pressurized section, an unpressurized service section, and a nosecone. Other primary structures include a welded aluminum pressure vessel, primary heat shield support structure, and back shell thermal protection system support structure. This structure supports secondary structures including the SuperDraco engines (for Dragon-2), propellant tanks, pressurant tanks, parachute system, and necessary avionics. The pressurized section consists of the welded pressure vessel, forward hatch, side hatch, docking tunnel, docking adapter, and windows. The Dragon-1 capsule's dry weight could range from 8,000 to 15,000 pounds depending on its cargo and configuration. The Dragon 2 capsule weighs approximately 16,976 pounds without cargo, with a height of 17 feet and a base width of 13 feet. Dragon's propulsion system uses nitrogen tetroxide (NTO) and monomethylhydrazine (MMH) propellant combination.

NASA program to launch astronauts to space station facing delays but 2019 still on target

WASHINGTON – NASA Administrator James Bridenstine said he still expects astronauts will fly from U.S. soil to the International Space Station by the end of next year even though an uncrewed test flight scheduled for Jan. 7 now could slip into the spring.
Bridenstine's acknowledgment that January is a "very low probability" window is the first time the agency has publicly cast doubt on the timing of the scheduled launch from Kennedy Space Center in Florida. The test flight of the SpaceX rocket and capsule is a key step in NASA's efforts to resume U.S. transport to Earth's orbit nearly a decade after the space shuttle was mothballed.
The administrator attributed the delay to challenges with several components, including landing parachutes. Some of those systems could be tested without flying them on the initial flight.
It's a matter of determining "what configuration are we willing to accept as an agency and are we willing to waive certain items (and) how do we test those items," Bridenstine told reporters at NASA headquarters.
But he said the test flight "will certainly be in the first half of 2019," a schedule that still would accommodate a crewed flight by the end of the year.
Earlier this year, Bridenstine said that "without question," such launches would resume in 2019.
NASA's multi-billion-dollar program to resume rocket launches to the ISS, known as Commercial Crew, has been a priority since Atlantis completed the last Space Shuttle mission in 2011.
Since then, U.S. taxpayers have been paying Russia to transport astronauts to the orbiting lab on Soyuz rockets at a cost that now exceeds $80 million per seat. At the same time, two companies have been working with NASA – Boeing and SpaceX – to develop a shuttle replacement at a cheaper price.

Boeing also is working on a test flight next year.
The test flight of SpaceX's Falcon 9 rocket and its Crew Dragon spacecraft is designed to assess ground systems, docking and landing operations. It also will provide valuable data toward NASA certifying SpaceX's crew transportation system for carrying astronauts to and from the space station.
The program to replace the space shuttle has not gone smoothly.
Even if a crewed launch arrives at the space station in 2019, it would be four years behind schedule.

When Commercial Crew was unveiled in 2010 under the Obama administration, the target date was 2015. But a lack of full funding from the Republican-controlled Congress led to delays. By the time Boeing and SpaceX won contracts in 2014, the date was pushed back to 2017. Further delays pushed schedules into next year.
Bridenstine also said he's confident the space station is "absolutely" safe.
On Aug. 29, ground teams detected what NASA said was a "minor" drop in pressure aboard the laboratory complex orbiting 250 miles up and housing three NASA astronauts, two Russian cosmonauts and a European.
An investigation found the leak to be an isolated incident.
"This has been evaluated many different ways," Bridenstine said. "It is not leaking now.it has been sealed up and we're all in agreement that it is safe."

New Target Date for SpaceX Demo-1

Bob Granath
Posted Dec 7, 2018 at 5:17 pm



NASA and SpaceX have agreed to move the target launch date of the uncrewed Demo-1 flight test to the International Space Station. SpaceX coordinated with the Eastern Range for a launch on Thursday, Jan 17. This adjustment allows the return of the Dragon spacecraft from the company's 16th commercial resupply services mission. SpaceX's Demo-1 will provide key data associated with the ground, integrated rocket and spacecraft, and autonomous docking systems, and the landing profile ahead of the company's flight test with astronauts, known as Demo-2.

"We still have more work to do as the certification process, hardware development and readiness reviews continue," said Kathy Lueders, manager of NASA's Commercial Crew Program. "The key readiness reviews along with NASA's continued analysis of hardware and software testing and certification data must be closed out prior to launch. The upcoming steps before the test missions are critical, and their importance can't be understated. We are not driven by dates, but by data. Ultimately, we'll fly SpaceX Demo-1 at the right time, so we get the right data back to support the in-flight abort test and the next test flight when our astronauts are aboard. However, the fact we're coordinating target dates with the Eastern Range is a great example of the real progress we're making with commercial crew and how close we are to actually flying American spacecraft and rockets from American soil again."

And there's official confirmation of what Hans from SpaceX said this week about a mid-January launch target. DM1 on #SpaceX's uncrewed demo now officially NET 17 January 2019. That puts launch at ~20:02 EST (0102 UTC on 18 Jan).

 Новая дата полёта Crew Dragon - 17 января! 

НАСА и SpaceX договорились с Восточным полигоном (Eastern Range) о дате запуска беспилотной миссии Demo-1 к Международной космической станции. SpaceX назначили запуск на четверг, 17 января. 

Эта корректировка позволяет вернуть грузовой космический корабль Dragon из миссии CRS-16. 

Миссия Demo-1 предоставит ключевые данные, связанные с наземными тестами, интеграцией ракеты с космическим кораблём, автономными стыковочными системами и профилем посадки перед летными испытаниями компании с астронавтами, известными как Demo-2.

"Нам еще предстоит проделать большую работу, поскольку процессы сертификации, разработки оборудования и проверки готовности продолжаются", - сказала Кэти Людерс (Kathy Lueders), менеджер Commercial Crew Program от НАСА.

"Ключевые обзоры готовности, а также постоянный анализ данных тестирования и сертификации оборудования и программного обеспечения НАСА должны быть закончены до запуска. Предстоящие процедуры перед тестовыми миссиями имеют решающее значение, и их важность не может быть занижена. Мы руководствуемся не датами, а данными. 

В конечном счете, мы запустим SpaceX Demo-1 в нужное время и получим данные, чтобы провести тест САС в полёте (in-flight abort test) и следующий тестовый полет, когда наши астронавты будут находиться на борту корабля. 

Однако тот факт, что мы согласовываем целевые даты с Восточным полигоном, является отличным примером реального прогресса, которого мы добиваемся с нашей командой, и того, насколько мы близки к тому, чтобы снова отправить человека на американских космических кораблях и ракетах в космос из США".
