ЦитироватьВсе это не имеет никакого значения, потому что на 1-й ступени скорее всего те же самые баллоны, только их в 4 раза больше.

Во вторых, не могу точно судить о критичности различий, но даже если баллоны те же самое, но их количество в 4 раза больше, как и баки в несколько раз больше, то это в значительной степени отличающаяся среда тестирования

Я уже писал, что имеет значение.
Т.к. на Фалькон-9 по циклограмме разные значения времени между началом заправки ЖК и гелия на первой и второй ступени.
На первой ступени Гелий начинают загружать через 4 минуты после начала заправки ЖК, а на второй ступени загрузка Гелия начинается через 6 минут 15 секунд после начала заправки ЖК.
Плюс времена заправок естественно разные.
Это уже как бы некие отличия, согласитесь и могут влиять как раз на графики формирования температур и давлений в баке

Ничто не мешает все эти скорости и времена поменять, если есть подозрение, что какие-то из значений менее безопасны чем другие.

Так же как и раньше - необходимо время на подготовку площадки к следующей РН.
Если только 2 пуска не распараллелены, т.е. работают 2 пусковые группы. Тогда промежуток между пусками уменьшается.

Сам по себе пуск Echostar 23 в этом месяце особо много не значит - AsiaSat-6/CRS-8 в течении двух недель уже пускали, в сентябре 2014-го, но в основном за счёт того что CRS-8 задержался и уехал вправо, а потом всё равно встали до января 15-го. Вот если запустят Echostar 23 через пару недель, а в феврале улетят CRS-10 и SES-10 - это будет другой разговор.

ЦитироватьA placeholder was refined to show a January 26th launch target – around midnight local time.
It is expected this date will slip to the right, via natural realignment as the flow moves closer to launch. However, it has remained set for over a week, and has since been classed as "Range Approved". The next update is expected in the next few days.

Ну вот наверное и первопричины того, что произошло 1-го сентября.
Хотели дотянуть возможности Фалькона-9 до вывода на ГПО спутников вроде Амос-6 и Echostar 23 (с посадкой) и залезли в экстремальные режимы.

ЦитироватьМне вот интересно. За все эти переносы Илон Маск никого не предупреждает о неполном служебом соответствии?

ЦитироватьПопав в SpaceX, новые сотрудники очень быстро понимают, действительно ли они способны выдержать это испытание. Многие увольняются в первые несколько месяцев из-за рабочей недели длительностью 90 и более часов. Другие уходят, не выдержав прямоты Маска и других руководителей на совещаниях. «Илон ничего о вас не знает и не думает, что чем-то может задеть ваши чувства, — продолжает Сингх. — Он знает лишь то, что, черт возьми, должно быть сделано. У тех, кому не удалось освоиться со стилем общения Маска, большие проблемы».

ЦитироватьСамым вопиющим примером бездушного отношения Маска к сотрудникам стало увольнение Мэри Бет Браун в начале 2014 года. Сказать, что она была его преданным ассистентом, — значит, не сказать ничего. Порой Браун чувствовала себя продолжением Маска — единственным существом, имевшим доступ во все его миры. Больше десяти лет она жертвовала ради него личной жизнью, каждую неделю моталась между Лос-Анджелесом и Кремниевой долиной, работала до поздней ночи и по выходным. Однажды Браун подошла к Маску и попросила, чтобы он повысил ей зарплату до уровня топ-менеджеров SpaceX, потому что на ней держится его график в двух компаниях, она много занимается пиаром и часто принимает управленческие решения. Маск предложил Браун уйти в отпуск на пару недель, во время которых он возьмет на себя ее задачи и оценит, насколько они тяжелы. Когда она вернулась, Маск заявил, что больше не нуждается в ее услугах и поручил составление своего графика ассистенту Шотвелл.

Very much still working this, but despite some good TEL testing at the pad over recent days (including a cool test relating to how the TEL will work differently than you've seen before at SLC-40), there's a lot of doubt about making Feb 3, or even close to that.
This is literally like a brand new pad, there's bound to be teething issues and you really don't want something failing on your pad at T-0!
Working is as it's not documented (where you see "X company requesting change to NET....") but what I'm being told. Could get interesting as CRS-10 is fast becoming a priority, with Dragon barging her shoulders in the line saying "I'm more important!" in a Jim-style "more than a ComSat launch" ;)
Again, working it, preliminary - but I always pass on launch date stuff out of L2/where ever as I know folk book flights/hotels. Don't change any plans, but have options to do so.

ЦитироватьL2 39A schedule has updated. No target for the Static Fire yet, but the launch date is NET March 12. Mainly to do with range availability.

So they'll finish the requirements of the 39A post launch "shakedown" work for turnaround to host the next F9, but will have to wait until the Range clears after the Delta IV launches, then have a Static Fire. They need the Range for the Static Fire, so you can see how March 12 is a NET based on WGS-8 scheduled for March 8...and how it makes "Static Fire to Launch" flow tight. So as always, a preliminary target and we'll know better in the second week of March.

It is launch week again for SpaceX as the company marches toward a planned weekend blastoff with a television broadcast satellite destined to cover Brazil.

The Falcon 9 rocket is inside SpaceX's hangar at launch pad 39A, where steps this week will include attaching the two-stage booster to a heavy-duty transporter-erector for rollout and a "static fire" test.

The transporter-erector was seen vertical at pad 39A in the last few days, but the mobile structure -- used to transfer rockets between the hangar and the pad -- was lowered Sunday and returned to the hangar, presumably for mating with the Falcon 9 booster.

A view of the transporter-erector Sunday at pad 39A is posted above.

The hotfire test is a critical milestone in any SpaceX launch campaign, exercising the rocket, ground systems and launch team to verify all systems are ready for the real countdown.

The rocket will be loaded with super-chilled kerosene and liquid oxygen propellants, and the first stage's Merlin 1D engines will ignite and ramp up to more than 1.5 million pounds of thrust for around three seconds. Hold-down restraints will keep the Falcon 9 on the ground.

It is not clear if the delay in the static fire will impact the launch date Sunday morning. Once SpaceX performs the test, the rocket must be returned to the hangar near pad 39A to receive the EchoStar 23 communications satellite it will carry into orbit.

SpaceX lowered the Falcon 9 rocket last night, and it remains horizontal at this hour as officials prepare for a possible static fire attempt this evening.

The test window opens at 6 p.m. EST (2300 GMT) and extends for six hours.

Meanwhile, the launch of the Falcon 9 rocket with the EchoStar 23 communications satellite remains set for early Sunday, with blastoff set for 12:34 a.m. EST (0534 GMT) at the opening of a two-and-a-half hour launch window.

The launch window spans the switch to Daylight Saving Time in on the U.S. East Coast.

The U.S. Air Force has issued the first official weather forecast for this weekend's mission, calling for mostly cloudy skies and a 70 percent chance of acceptable conditions early Sunday morning.

"On Friday, the next system to impact the Space Coast gets organized over Texas," the forecast team at the 45th Weather Squadron wrote on today's outlook. "This new low pressure system will bring upper-level clouds into the (Florida) Panhandle by Saturday evening. As the system moves into the Gulf Coast States during the launch window Sunday, the clouds will begin encroaching over the area."

The primary weather concern is violating the thick cloud layer rule, according to the Air Force.

The outlook calls for isolated rain showers, scattered clouds at 3,000 feet, broken clouds at 22,000 feet, southeast winds at 15 to 20 mph, and a launch time temperature of 68 degrees Fahrenheit.

There is a backup launch opportunity available early Tuesday morning, March 14, when there is again a 70 percent chance of favorable weather conditions.

There are signs that the target launch date for SpaceX's launch of the EchoStar 23 communications satellite is being delayed from Sunday. Managers have not set an official new launch date.

SpaceX had reserved March 14 for a backup launch opportunity, so that will be the next chance for the mission to blast off from pad 39A at NASA's Kennedy Space Center in Florida, assuming the launcher and payload are ready.

A cherry picker is visible hovering above the Falcon 9 rocket laying horizontal at the launch pad, presumably to enable inspections or other work on the booster.

A hotfire of the rocket's nine Merlin 1D engines originally scheduled for yesterday was rescheduled for today, but there has been no indication that the test, a critical preflight milestone, will go forward today.

SpaceX officials declined comment.

Here's a view of pad 39A and the Falcon 9 rocket earlier today taken by CBS News' William Harwood.

The Falcon 9 rocket is vertical again this morning as SpaceX presses on with plans for a countdown rehearsal that will culminate in fueling the two-stage launcher and lighting its nine main engines for around three seconds.

Attempts to perform the static fire were thwarted the last two days by apparent technical issues, and the Falcon 9 was lowered yesterday as ground crews swarmed around the rocket. But the raising of the Falcon 9 vertical today could be a sign the hotfire test may be back on track.

The Falcon 9 is without its payload -- the EchoStar 23 communications satellite -- which will be added once the hotfire test is completed and the rocket is returned to its hangar at the southern edge of pad 39A.

Target T-0 for the Falcon 9 Static Fire is 6pm local (11pm UTC). Rocket is vertical again, so that's a very good sign per Wednesday's issue.

Technology upgrades and standardization at the Eastern Range have expanded its throughput for launches and rehearsal operations. Before modernization, it generally took about a week to reconfigure the Range from supporting one kind of rocket to another. Now it takes only a day or two, significantly expanding the availability of launch dates.

CAPE CANAVERAL, Fla. — SpaceX (http://www.spacex.com/) is set to launch its second Falcon 9 (http://www.spaceflightinsider.com/hangar/falcon/) rocket fr om Kennedy Space Center's Launch Complex 39A. Liftoff is targeted for the beginning of a 2.5-hour long window that opens at 1:34 a.m. EDT (05:34 GMT) March 14, 2017.

The weather outlook (http://www.patrick.af.mil/Portals/14/documents/Weather/L-2%20Forecast%2014%20Mar%20Launch.pdf?ver=2017-03-11-064835-333) for March 14 is somewhat favorable with a 30 percent chance of a violation of launch constraints. The primary concern is thick clouds. Should a delay occur, SpaceX has a backup attempt penciled in for March 16. The primary weather concern that morning will be liftoff winds.

 The 230-foot (70-meter) tall Falcon 9 rocket will be sending the EchoStar 23 communications satellite to space. As the payload is heavy enough and will be placed into a high-energy geostationary transfer orbit (GTO), it will need as much fuel as possible. As such, a first stage recovery will not be attempted. The last time a SpaceX rocket flew without landing legs was in April 2015.

Спойлер

This flight is expected to be the last planned expendable Falcon 9. A future iteration of the vehicle, the "Block 5 (http://www.spaceflightinsider.com/organizations/space-exploration-technologies/next-spacex-launch-may-one-of-the-last-expendable-falcon-9-booster/)," will debut sometime in late-2017 and will include improved landing legs, increased thrust, as well as other enhancements that will increase performance and shorten the turnaround time for recovered boosters.

To date, SpaceX has recovered eight Falcon 9 first stages. The company plans to reuse one of those boosters on the next flight, which will send the SES-10 communications satellite into space.

For this mission, however, the focus is on EchoStar 23. The spacecraft was built by Space Systems/Loral (SS/L) and will be operated by the EchoStar corporation.

The spacecraft is intended to primarily service markets in South America. After being placed into GTO, the vehicle will use its onboard thrusters to circularize its orbit at more than 22,000 miles (35,000 kilometers) over the equator, a location known as geostationary orbit.

In particular, EchoStar 23 (http://nextvnews.com/echostar-to-finally-launch-satellite-for-position-45-west-to-provide-tv-services-in-brazil/) will be placed at 45 degrees west longitude in order to supply Brazil television services. It has a planned lifetime of 15 years.

EchoStar 23 is a Ku-band satellite (http://echostar.com/launch.aspx). It has four main reflectors with multiple sub-reflectors. According to Gunter's Space Page (http://space.skyrocket.de/doc_sdat/echostar-23.htm), the satellite tips the scales at about 12,100 pounds (5,500 kilograms) and is built around the SSL-1300 spacecraft platform. Additionally, it has two deployable solar arrays that will produce 20 kilowatts of power.

SS/L announced in 2014 (http://sslmda.com/html/pressreleases/pr20140429.html) it was sel ected by EchoStar to build the satellite. It was originally planned to launch in 2016, however, because of SpaceX's Sept. 1, 2016, launch pad explosion (http://www.spaceflightinsider.com/organizations/space-exploration-technologies/spacex-falcon-9-amos-6-explodes-slc-40/), which destroyed a Falcon 9 rocket with its satellite payload during a pre-flight fueling test, all flights were suspended until the cause of the anomaly was determined.

 In January 2017, SpaceX resumed Falcon 9 flights (http://www.spaceflightinsider.com/organizations/space-exploration-technologies/spacexs-falcon-9-soars-skyward-with-10-iridium-next-satellites/) with the West Coast launch of 10 Iridium satellites. It was expected EchoStar 23 would be the second launch after the Iridium-1 return-to-flight mission, and thus the first to launch fr om the newly renovated Launch Complex 39A. But because additional testing was needed at the pad, it was decided to fly the critical CRS-10 (http://www.spaceflightinsider.com/organizations/space-exploration-technologies/ksc-launch-complex-39a-begins-new-life-spacex-crs-10-launch/) International Space Station resupply mission first.

Nearby Space Launch Complex 40, where the company has traditionally launched Falcon 9 rockets from on the East Coast, remains out of service after it was damaged by the Sept. 1 explosion. Repairs are expected to be completed by late summer 2017.

After the CRS-10 mission was out of the way, processing for EchoStar 23's mission was able to move forward. On March 7, 2017, the rocket that will be used to send the satellite skyward was moved from SpaceX's horizontal integration facility and raised to the vertical position for a static fire test. The company performs these evaluations, which involve fully fueling the rocket and counting down to zero for a short three-second engine ignition, to verify all is working properly.

This test, however, was postponed (http://www.spaceflightinsider.com/organizations/space-exploration-technologies/echostar-23-launch-postponed-net-march-14/) to March 8, wh ere it was again delayed. Ultimately, the firing occurred on March 9 (http://www.spaceflightinsider.com/organizations/space-exploration-technologies/falcon-9-echostar-23-conducts-static-fire-test/). This prompted the launch to be moved fr om March 12 to its current date of March 14. Engineers are currently poring over the data to ensure everything went nominally with the static fire.

After the test, the rocket, which did not have the payload on top, was rotated back to the horizontal position and rolled back into the hangar wh ere engineers are working to install the payload.

Tuesday morning's liftoff will be the third mission of the year for SpaceX and the 31st Falcon 9 since the first flight in 2010. Additionally, this will be the Space Coast's third rocket launch of 2017.

SpaceX is expected to transfer its next Falcon 9 rocket to launch pad 39A at NASA's Kennedy Space Center in Florida on Monday with a direct-to-home television broadcast satellite on-board, setting up for a two-and-a-half hour predawn launch window Tuesday.

The Falcon 9 rocket will ride a heavy-duty transporter-erector system for the quarter-mile (400-meter) rollout from a horizontal assembly hangar at the southern edge of pad 39A. The carrier, which doubles as an umbilical mast during launch countdowns, will hydraulically hoist the 229-foot-tall (70-meter) rocket upright once it arrives at the top of the incline leading to the pad.

SpaceX will verify connections between the transporter-erector strongback and ground supplies of propellant, power and other systems needed during Monday night's launch countdown.

Since Thursday, when the Falcon 9 rocket performed a hold-down engine firing at pad 39A, engineers returned the launcher to its hangar and attached a U.S.-owned commercial communications on its way to space to provide television broadcast services across Brazil.

The EchoStar 23 satellite was already encapsulated inside the Falcon 9's payload fairing after being fueled and prepared for liftoff inside a nearby clean room facility.

The Falcon 9 launch conductor will poll the launch team for a "go" for fueling of the two-stage rocket at 12:16 a.m. EDT (0416 GMT), followed by the start of tanking with RP-1 kerosene fuel around eight minutes later.

Super-chilled liquid oxygen propellant, cooled to near its freezing point, will begin pumping into the Falcon 9 at T-minus 45 minutes.

The computer-controlled countdown will prep the rocket's nine Merlin 1D main engines for ignition, transition the Falcon 9 to internal battery power, and pressurize the booster's propellant tanks in the last 10 minutes of the countdown.

The launch window Tuesday opens at 1:34 a.m. EDT (0534 GMT) and runs until 4:04 a.m. EDT (0804 GMT).

Officials will be watching the weather during Tuesday morning's launch window, with forecasters predicting mostly cloudy skies and isolated rain showers in the forecast.

The weather outlook issued by the U.S. Air Force's 45th Weather Squadron on Sunday calls for a 60 percent chance that conditions will be favorable for a launch. A weather system over Florida was triggering scattered rain showers over the Space Coast and adjacent waters of the Atlantic Ocean late Sunday.

"This system will be very slow to transit Central Florida, keeping cloud cover and isolated showers over the Space Coast through the day on Monday," the Air Force weather team wrote in a forecast released Sunday.

Meteorologists believe weather conditions will improve overnight and throughout the launch window.

"The frontal boundary associated with the system should push south of the spaceport by Monday evening. This will allow the extensive cloud cover to begin diminishing and become shallower through the countdown. The primary weather concern for launch Tuesday morning will be lingering thick clouds that haven't cleared through the spaceport area."

The official forecast calls for scattered clouds at 3,000 feet and 12,000 feet, and a broken deck of clouds at 22,000 feet. Winds will be from the west at 15 to 20 mph, and the temperature at launch time should be around 64 degrees Fahrenheit.

Cooler conditions are on tap across the Space Coast later in the week. If the rocket is unable to take off Tuesday, there is an 80 percent chance of acceptable weather during the Falcon 9's backup window Thursday morning.

After liftoff, the slender white launcher will pitch on an easterly course from Cape Canaveral atop more than 1.5 million pounds of thrust, heading over the Atlantic on the way to a high-altitude geostationary transfer orbit, the drop-off point for most large telecom satellites.

Its first stage engines will shut off and fall away around two-and-a-half minutes into the flight, and the Falcon 9's single Merlin upper stage engine will ignite two times to deliver the EchoStar 23 satellite into its intended egg-shaped orbit.

The Falcon 9's first stage booster will fall into the Atlantic without trying to land on SpaceX's recovery ship. The heavyweight EchoStar 23 satellite requires all of the Falcon 9's lift capacity, leaving no fuel leftover to attempt a powered descent and touchdown.

The rocket is stripped of the four landing legs usually fastened to the base of the first stage, the first time a Falcon 9 has launched without the landing gear since April 2015.

Diverging from the public disclosure practices by most commercial launch and satellite companies, SpaceX and EchoStar have not revealed the parameters — such as the altitude and inclination — of the orbit targeted on Tuesday's flight.

But the orbit will likely range in altitude from a few hundred miles above Earth to approximately 22,300 miles (nearly 36,000 kilometers).

An EchoStar spokesperson also declined to provide the mass of the EchoStar 23 satellite, which was manufactured by Space Systems/Loral in Palo Alto, California. Based on the SSL 1300 satellite bus, EchoStar 23 was ordered by EchoStar Satellite Services in 2014 and is based on the spacecraft chassis originally built for the CMBStar mobile communications station, a venture into the Chinese market led by EchoStar and canceled in 2008.

The tri-band EchoStar 23 satellite is designed with flexibility, according to EchoStar, with the ability to carry out multiple types of missions. Its communications payload includes Ku-band, Ka-band and S-band transponders.

EchoStar 23's first operating post in geostationary orbit will be along the equator at 45 degrees west longitude, once the spacecraft completes a series of burns with its own main engine to circularize its orbit from the initial transfer orbit reached by the Falcon 9.

The craft was originally supposed to launch by the end of 2016, in time to meet a licensing deadline from ANATEL, the Brazilian communications regulatory agency, that requires EchoStar 23 be in service by the end of June.

EchoStar says it will meet that deadline for the Ku-band spectrum, which the company intends to use for television broadcast services in Brazil. The operator has sought an extension on the Ka-band and S-band deadlines, EchoStar said in its annual report released Feb. 24.

The company said is still exploring options to use its Ka-band and S-band spectrum rights by the regulatory deadline in mid-2017.

Rippling delays in SpaceX's launch manifest caused the slip in EchoStar 23's liftoff after a Falcon 9 rocket exploded Sept. 1 on a launch pad at Cape Canaveral, grounding SpaceX missions more than four months.

Tuesday's launch will the third SpaceX rocket flight since the launch operator resumed service Jan. 14 with a successful Falcon 9 blastoff from California with 10 Iridium communications satellites.

SpaceX dispatched a Dragon supply ship to the International Space Station on a Feb. 19 launch from Florida, the first time the company has flown from pad 39A, which it leases from NASA.

Launch pad 39A was the starting point for all of NASA's Apollo moon landing missions, plus the majority of space shuttle flights, including the first and last launches in 1981 and 2011.

The launch of EchoStar 23 will be the 31st Falcon 9 flight overall since the privately-developed booster debuted in June 2010.

This week's SpaceX mission marks the start of a busy few weeks of launch activity on Florida's Space Coast.

Two United Launch Alliance rockets, a Delta 4 and an Atlas 5, are due for liftoff soon.

A Delta 4 rocket is scheduled to launch Friday, March 17, with the U.S. Air Force's WGS 9 communications satellite built with funding from military partners in Canada, Denmark, the Netherlands, Luxembourg and New Zealand.

An Atlas 5 launcher is set for liftoff March 21 with a NASA-contracted, commercially-owned Orbital ATK Cygnus cargo carrier with supplies and experiments to the International Space Station.

SpaceX's next launch, set for no earlier than March 27, will loft the SES 10 communications satellite for SES of Luxembourg. That mission will mark the first time SpaceX has launched a Falcon 9 powered by a previously-flown first stage, a major leap in the firm's cost-cutting reusability initiative.

SpaceX lifted the Falcon 9 rocket vertical at pad 39A earlier this morning as engineers proceed toward an early Tuesday launch opportunity to loft the EchoStar 23 communications satellite.

The spacecraft, built in California and owned by Colorado-based EchoStar Satellite Services, is about to kick off a 15-year mission broadcasting television across Brazil, and potentially conducting other telecom relay functions.

The 229-foot-tall (70-meter) rocket is set for blastoff at 1:34 a.m. EDT (0534 GMT) Tuesday at the opening of a two-and-a-half hour launch window.

After liftoff, the slender white launcher will pitch on an easterly course from Cape Canaveral atop more than 1.5 million pounds of thrust, heading over the Atlantic on the way to a high-altitude geostationary transfer orbit, the drop-off point for most large telecom satellites.

The official launch weather forecast released by U.S. Air Force meteorologists this morning now predicts a 60 percent chance conditions will prohibit a liftoff early Tuesday.

"Overcast skies, widespread showers and isolated thunderstorms are expected over Central Florida today, associated with a deepening low pressure moving in from the Gulf of Mexico," the weather forecasters wrote Monday. "The frontal boundary associated with the system will not push south of the spaceport until late Monday night. Then cloud cover will begin diminishing, which will continue through the countdown and launch window. The primary weather concern for Tuesday will be lingering thick clouds that haven't cleared through the spaceport area."

The two-and-a-half launch window opens at 1:34 a.m. EDT (0534 GMT).

The outlook calls for cloudy weather and isolated rain showers diminishing through the launch window, with scattered clouds at 3,000 feet, broken clouds at 12,000 feet, and an overcast deck at 22,000 feet. Winds will be from the west-southwest at 15 to 20 mph, and the temperature at launch time should be around 64 degrees Fahrenheit.

Clearing skies and cooler temperatures are in the forecast later Tuesday. If launch does not occur Tuesday, the next opportunity is early Thursday, when conditions will be more favorable for a launch, with a 90 percent chance of good weather.

 March 13, 2017 (https://spaceflightnow.com/2017/03/)    Stephen Clark (https://spaceflightnow.com/author/stephen-clark/)

 SpaceX's Falcon 9 rocket is set for liftoff from Cape Canaveral early Tuesday, heading due east over the Atlantic Ocean to deliver the EchoStar 23 communications satellite into orbit 34 minutes later.

The 229-foot-tall (70-meter) rocket is poised for launch from pad 39A at NASA's Kennedy Space Center in Florida at 1:34 a.m. EDT (0534 GMT) Tuesday at the opening of a 150-minute launch window.

Perched atop the rocket is the EchoStar 23 communications satellite, a spacecraft made by Space Systems/Loral, ready to beam television programming across Brazil for EchoStar Satellite Services The rocket will place the satellite into a high-altitude geosynchronous transfer orbit.

The timeline below outlines the launch sequence for the Falcon 9 flight with EchoStar 23. On this mission, SpaceX does not plan to attempt a recovery of the rocket's first stage booster due to the high performance required to place the heavy EchoStar 23 spacecraft into a high-altitude orbit.

The Falcon 9 does not carry landing legs, the first SpaceX launch without landing gear since April 2015.

It's been a rainy afternoon at NASA's Kennedy Space Center, with more showers on the way crossing the Florida peninsula as night calls on the Space Coast this evening.

SpaceX and U.S. Air Force meteorologists will be watching the thick cloud rule closely tonight. The rule prevents a launch if clouds are thicker than 4,500 feet and extend into the freezing layer.

Final launch preps this evening will include the evacuation of the launch pad prior to fueling, activation of the Falcon 9's computer and navigation system, and a prelaunch poll by the SpaceX launch conductor at 12:16 a.m. EDT (0416 GMT) to verify all consoles are "go" for the terminal countdown.

Super-chilled RP-1 kerosene fuel will be loaded first into the two-stage booster, beginning around 12:24 a.m. EDT (0424 GMT). Liquid oxygen, chilled and densified near its freezing point, will follow starting at around 12:49 a.m. EDT (0449 GMT).

The computer-controlled countdown will prep the rocket's nine Merlin 1D main engines for ignition, transition the Falcon 9 to internal battery power, and pressurize the booster's propellant tanks in the last 10 minutes of the countdown.

The launch window Tuesday opens at 1:34 a.m. EDT (0534 GMT) and runs until 4:04 a.m. EDT (0804 GMT).

ЦитироватьPhotos: Falcon 9 booster, minus landing legs and grid fins, poised for launch
 March 13, 2017 (https://spaceflightnow.com/2017/03/)     Stephen Clark (https://spaceflightnow.com/author/stephen-clark/)

 A 229-foot-tall (70-meter) SpaceX Falcon 9 rocket stood on launch pad 39A at NASA's Kennedy Space Center on Monday afternoon on the eve of a scheduled blastoff with the EchoStar 23 television broadcast satellite.

The two-stage rocket will fly without the four landing legs and grid fins normally carried on Falcon 9 missions. That's because this rocket's first stage will not attempt a landing at sea, instead plummeting into the Atlantic Ocean in a practice normally used on expendable launchers.

SpaceX has recovered eight first stage boosters in 13 tries since early 2015. The launch of EchoStar 23 requires all of the Falcon 9's lift capacity, leaving insufficient leftover RP-1 kerosene and liquid oxygen propellants to reignite its Merlin engines and slow down for landing.

The company intends to launch a previously-flown booster for the first time before the end of March on a flight from Florida with the SES 10 communications satellite. SpaceX believes reusing the rocket stage will reduce the cost of launch services.

The EchoStar 23 communications satellite, cocooned inside the Falcon 9's nose cone, is beginning a 15-year mission broadcasting television programming across Brazil.

The EchoStar 23 launch will mark the 31st flight of a Falcon 9 rocket, the third Falcon 9 mission of 2017, and SpaceX's second mission to take off from pad 39A.

Countdown preps are continuing at this time, now less than four hours from the opening of tonight's launch window.

Weather will be a big watch item tonight, with steady rain falling across Central Florida and more precipitation streaming onshore from the Gulf Mexico and pushing across the peninsula at this hour.

Tonight's launch window opens at 1:34 a.m. EDT (0534 GMT) and extends for two-and-a-half hours, giving SpaceX some time to wait out the weather if necessary.

Closer to propellant loading, SpaceX will decide whether to go for the opening of the window or target a later T-0 to catch a gap in clouds.

T-minus 1 hour, 55 minutes and counting. Good evening fr om the Kennedy Space Center, wh ere light rain is falling.

There are several changes to the Falcon 9 countdown that were first introduced Jan. 14 on a launch from California, the first SpaceX mission after a rocket exploded on a launch pad at Cape Canaveral Air Force Station in September.

Engineers changed the filling sequence to avoid the problem of liquid oxygen becoming trapped in voids between helium pressurant tanks and their composite overwraps, which SpaceX says most likely caused the explosion last year.

When it debuted a more capable Falcon 9 configuration burning super-chilled densified propellants in 2015, SpaceX shortened its launch countdowns to begin pumping fuel and oxidizer into the rocket just 35 minutes before blastoff. SpaceX's previous Falcon 9 countdowns followed a practice employed universally on cryogenically-fueled rockets worldwide, in which propellants are loaded aboard several hours ahead of launch.

The "load and go" countdowns caused headaches at first, leading to several aborts and delays before SpaceX gained experience with the practice early last year. The late fueling plan has also drawn questions from NASA safety advisors, who worry the procedure will endanger astronauts strapped into to SpaceX's Crew Dragon spaceships, which the company is developing to ferry people to and from the space station.

The timeline for today's countdown calls for RP-1 kerosene, chilled to around 20 degrees Fahrenheit (minus 6 degrees Celsius), to begin flowing into the two-stage rocket at T-minus 70 minutes. Liquid oxygen loading will follow at T-minus 45 minutes.

A poll of the SpaceX launch team is expected at T-minus 78 minutes to give a "go" for fueling operations.

The SpaceX launch conductor just gave the go to start propellant loading on-time. The weather continues to be an issue, with cloud conditions currently in violation of the Falcon 9's launch commit criteria. Ground winds are still within limits, but trending a bit higher than expected.

SpaceX is also awaiting balloon data to determine if upper level winds are acceptable tonight.

T-minus 70 minutes. The launch autosequence has started, kicking off the first steps to begin pumping propellants into the 229-foot-tall Falcon 9 at launch pad 39A.

RP-1 kerosene will be pumped into the two-stage Falcon 9 rocket first, followed by liquid oxygen chilled to near minus 340 degrees Fahrenheit (minus 206 degrees Celsius) at T-minus 45 minutes.

Another launch attempt is on tap tonight as clear weather dominates along Florida's Space Coast.

Liftoff from pad 39A is set for 1:35 a.m. EDT (0535 GMT), and the forecast calls for a 90 percent chance of favorable conditions during the two-and-a-half hour launch window.

The 229-foot-tall rocket has remained vertical at the seaside launch facility after high winds scrubbed a launch attempt in the predawn hours Tuesday.

Final launch preps this evening will include the evacuation of the launch pad prior to fueling, activation of the Falcon 9's computer and navigation system, and a prelaunch poll by the SpaceX launch conductor at 12:17 a.m. EDT (0417 GMT) to verify all consoles are "go" for the terminal countdown.

Super-chilled RP-1 kerosene fuel will be loaded first into the two-stage booster, beginning around 12:25 a.m. EDT (0425 GMT). Liquid oxygen, chilled and densified near its freezing point, will follow starting at around 12:50 a.m. EDT (0450 GMT).

The computer-controlled countdown will prep the rocket's nine Merlin 1D main engines for ignition, transition the Falcon 9 to internal battery power, and pressurize the booster's propellant tanks in the last 10 minutes of the countdown.

ЦитироватьВАШИНГТОН, 16 мар – РИА Новости. Ракета-носитель Falcon 9 компании SpaceX стартовала с космодрома на мысе Канаверал во Флориде с коммерческим телекоммуникационным спутником EchoStar 23, компания ведет трансляцию запуска.

Старт был дан в расчетные 09:00 мск со стартовой площадки 39А. Ракета-носитель выводит на геостационарную орбиту спутник, принадлежащий корпорации EchoStar, предназначенный для передачи телевизионного сигнала странам Южной Америки.

Запуск EchoStar 23 планировался на 2016 год, но был отложен из-за взрыва в сентябре прошлого года в ходе предстартовых испытаний ракеты Falcon 9. Попытка запуска во вторник 14 марта была отложена по погодным условиям из-за сильного ветра.

Спутник, срок работы которого рассчитан на 15 лет, был создан компанией Space Systems/Loral (SS/L). Аппарат весом около 5,5 тонны, будет работать на геостационарной орбите.

 CAPE CANAVERAL AIR FORCE STATION, Fla. --
 
The U.S. Air Force's 45th Space Wing supported SpaceX's successful launch of the EchoStar XXIII spacecraft aboard a Falcon 9 rocket from Launch Complex 39A at NASA's Kennedy Space Center March 16 at 2 a.m. EDT.
EchoStar 23, designed and built by Space Systems Loral for EchoStar Corporation, will provide television broadcast services over Brazil with an estimated service life of 15 years.

This launch marks the last SpaceX Falcon 9 launch utilizing ground-based mission flight control personnel and equipment in the mission control center.  All future SpaceX rockets will utilize an Autonomous Flight Safety System which replaces the ground-based mission flight control personnel and equipment with on-board Positioning, Navigation and Timing sources and decision logic.  The benefits of AFSS include increased public safety, reduced reliance on range infrastructure, reduced range spacelift cost, increased schedule predictability and availability, operational flexibility, and launch slot flexibility. 
SpaceX's CRS-10 launch Feb.18 from LC 39A marked the historic first-ever launch utilizing AFSS on either of Air Force Space Command's Eastern or Western Ranges.    

The Falcon 9 Echostar XXIII launch was the third major launch operation for the Eastern Range this year and the second from LC 39A.  Before any spacecraft can launch on the range, a combined team of military, government civilians and contractors from across the 45th Space Wing provide the mission assurance to ensure a safe and successful lift-off for range customers.

"We truly have a tremendous team here on the Space Coast and it's my honor to be a part of this mission supporting the commercial space industry," said Brig. Gen. Wayne Monteith, 45th Space Wing commander and Launch Decision Authority for this mission.  "Assured access to space is a team sport here on the Eastern Range.  This operation once again clearly demonstrates the successful collaboration we have with our mission partner SpaceX as we continue to shape the future of America's space operations and showcase why the 45th Space Wing is the 'World's Premier Gateway to Space.'"

Since the late 1960s, LC 39A has served as the starting point for America's most significant human spaceflight endeavors such as the Apollo 11 launch for the first manned moon landing in 1969 and the first Space Transportation System mission in 1981 with the launch of the Space Shuttle Columbia, also named STS-1.  Thirty years later, NASA's 135th and final mission of the Space Shuttle program, STS-135, successfully launched the orbiter Atlantis from LC 39A.

KENNEDY SPACE CENTER, Fla. — Lighting up the Florida night skies, an expendable SpaceX Falcon 9 (http://www.spaceflightinsider.com/hangar/falcon/) rocket soared toward space with the EchoStar 23 satellite after lifting off from historic Launch Complex 39A. Liftoff took place at 2 a.m. EDT (06:00 GMT) March 16, 2017, some 25 minutes into a 2.5-hour long window.

The launch was postponed from March 14 (http://www.spaceflightinsider.com/organizations/space-exploration-technologies/weather-wins-as-spacex-scrubs-launch-of-falcon-9-with-echostar-23/), ultimately because of high winds. Throughout the first attempt's countdown, weather was spotty at best with conditions periodically entering rule-violating territory.

For this second attempt, however, conditions were much better. Despite being pushed 25 minutes into the launch window because of high-altitude winds, the countdown went by the book. The 45th Space Wing, which supports launches from the Space Coast, predicted the weather would have a 90 percent (http://www.patrick.af.mil/Portals/14/documents/Weather/L-1%20Forecast%2016%20Mar%20Launch.pdf?ver=2017-03-14-021232-447) chance of favorable conditions, with high winds being the primary concern.

 "We truly have a tremendous team here on the Space Coast and it's my honor to be a part of this mission supporting the commercial space industry," said Brig. Gen. Wayne Monteith, 45th Space Wing commander and Launch Decision Authority for this mission. "Assured access to space is a team sport here on the Eastern Range. This operation once again clearly demonstrates the successful collaboration we have with our mission partner SpaceX as we continue to shape the future of America's space operations and showcase why the 45th Space Wing is the 'World's Premier Gateway to Space.'"

EchoStar 23 was the payload for the 230-foot tall Falcon 9. Because the communications satellite was heavy enough and traveling to a high-energy geostationary transfer orbit (GTO), the rocket needed as much fuel as possible. As such, a first stage recovery was not attempted.

This was the first legless SpaceX booster since April 2015 and is expected to be one of the last expendable (https://twitter.com/elonmusk/status/822926184719609856) Falcon 9 rockets. According to SpaceX CEO and founder Elon Musk, future payload like EchoStar 23 will either be flown on a Falcon Heavy or an upgraded "Block 5 (http://www.spaceflightinsider.com/organizations/space-exploration-technologies/next-spacex-launch-may-one-of-the-last-expendable-falcon-9-booster/)" Falcon 9.

The SpaceX launch conductor took the launch readiness poll (http://www.spacex.com/sites/spacex/files/echostarxxiiifinal.pdf) at around 12:48 a.m. EDT (04:48 GMT). Loading of rocket grade kerosene into both stages began at 70 minutes before liftoff. That was followed by liquid oxygen 45 minutes before liftoff.

At seven minutes before liftoff, the nine Merlin 1D engines at the base of the Falcon 9 began a chill phase to condition them before launch. About five minutes later, the Range Control Officer verified the range was clear for flight.

About 60 seconds before launch, the propellant tanks were pressurized. At three seconds to liftoff, the nine Merlin 1D engines ignited and powered up to full throttle. Once the onboard computer deemed all was well, the launch mounts were commanded to release the vehicle.

Meanwhile, once the rocket was released, the strongback, the structure used to transport the Falcon 9 from the hangar to the launchpad and lift it to the vertical position, performed a movement known as the "throwback" wh ere the whole structure rapidly moved out of the way of the rising rocket. The strongback lowered to about 45 degrees from the vertical position in about 8 seconds.

 Producing 190,000 pounds (845 kilonewtons) of thrust each, the nine Merlin 1D engines powered the vehicle vertically to clear the tower at LC-39A. Then the rocket began its pitch, yaw and roll maneuver toward its designated geostationary transfer orbit.

Just after a minute into flight, the vehicle surpassed the speed of sound and the moment of peak mechanical stress on the rocket known as Max Q.

At 2 minutes, 43 seconds, the first stage engines shut down. Four seconds later, the first and second stages separated.

 Eight seconds after separating, the single Merlin 1D Vacuum engine ignited and powered to full throttle. It produced about 205,000 pounds (914 kilonewtons) of thrust as it continued to push it and EchoStar 23 to orbit.

The second stage fired for about five-and-a-half minutes. During that time, at 3 minutes, 43 seconds, the vehicle was far enough out of the atmosphere and the fairing was no longer needed to protect EchoStar 23. As such, it was jettisoned.

At 8 minutes, 31 seconds, the second stage engine cut out as planned. The booster and spacecraft were in orbit.

At 2:26 a.m. EDT (06:26 GMT), after spending 18 minutes coasting, the Merlin engine ignited for a second time, this time for a 1-minute burn, to increase the higher end of its orbit to around 22,000 miles (35,000 kilometers) – geostationary transfer orbit.

EchoStar 23 separated from the second stage 34 minutes after leaving LC-39A. Next the satellite will deploy its solar panels and begin circularizing its orbit at 22,000 miles (35,000 kilometers) using its own engines.

Once at this altitude, the spacecraft will orbit Earth at the same rate the planet rotates. This allows a spacecraft to "hover" over a specific spot. In this case, EchoStar 23 will stay over South America at 45 degrees West longitude (http://nextvnews.com/echostar-to-finally-launch-satellite-for-position-45-west-to-provide-tv-services-in-brazil/) to provide television services to Brazil.

EchoStar 23 was built by SSL and will be operated by the EchoStar corporation. It has an expected lifespan of 15 years.

The spacecraft is a Ku-band satellite (http://echostar.com/launch.aspx). It has four main reflectors with multiple sub-reflectors. According to Gunter's Space Page (http://space.skyrocket.de/doc_sdat/echostar-23.htm), it weighs about 12,100 pounds (5,500 kilograms) and is built around the SSL-1300 spacecraft platform. Moreover, it has two deployable solar panels that will produce 20 kilowatts of power.

This was the third Falcon 9 rocket to fly in 2017 and the second to utilize LC-39A. It was also the 31st Falcon 9 since its inaugural flight in 2010.

According to the 45th Space Wing, this was the last SpaceX Falcon 9 launch to utilize the Eastern Range's ground-based mission flight control personnel and equipment in the mission control center.

"All future SpaceX rockets will utilize an Autonomous Flight Safety System which replaces the ground-based mission flight control personnel and equipment with on-board Positioning, Navigation and Timing sources and decision logic," a statement (http://www.patrick.af.mil/News/Article-Display/Article/1120143/45th-sw-supports-successful-falcon-9-echostar-xxiii-launch) by the 45th Space Wing reads.

The 45th Space Wing said the benefits of the automated system include increased public safety, reduced reliance on range infrastructure, reduced range spacelift cost, increased schedule predictability and availability, operational flexibility, and launch slot flexibility.

Overall, this is part of the Range's plan to be able to support up to 48 launches (http://www.spaceflightinsider.com/space-centers/ccafs/automated-flight-safety-improving-space-access/) from the Space Coast each year by 2020.

SpaceX's next launch is expected to be the first flight to utilize a recovered Falcon 9 first stage. The SES-10 mission will see the same booster recovered during the CRS-8 mission back in April 2016. Liftoff is currently targeted for no earlier than late March 2017.

Up next (http://www.spaceflightinsider.com/organizations/orbital-sciences-corp/ula-oa-7-confirmed-launch-march-24-wgs-9-set-march-18/) for the Space Coast will be the launch of a Delta IV Medium+ 5,4 rocket with the ninth Wideband Global SATCOM satellite. It is targeting a liftoff at 7:44 p.m. EDT (23:44 GMT) March 18. After that, an Atlas V carrying the S.S. John Glenn Cygnus cargo spacecraft to the International Space Station will launch on March 24.

If all goes as currently scheduled, that will make three launches in about eight days from the Space Coast.

ECHOSTAR XXIII MISSION

On March 16, 2017, SpaceX's Falcon 9 successfully delivered EchoStar XXIII, a commercial communications satellite for EchoStar Corporation, to a Geostationary Transfer Orbit (GTO).  EchoStar XXIII is a highly flexible, Ku-band broadcast satellite services (BSS) satellite with four main reflectors and multiple sub-reflectors supporting multiple mission profiles. Initial commercial deployment of EchoStar XXIII will be at 45° West, and the Satellite End of Life (EOL) Power is 20 kilowatts (kW).

Below is a summary of the mission in photos, with more photos available on our Flickr site (http://www.flickr.com/spacex). You can also watch the archived webcast here (https://youtu.be/lZmqbL-hz7U), and find more information about the mission in our press kit (http://www.spacex.com/sites/spacex/files/echostarxxiiifinal.pdf).

Falcon 9 lifted off from Launch Complex 39A at NASA's Kennedy Space Center at 2:00 am EDT, 6:00 am UTC.

** The GOES-16 data posted on this page are preliminary, non-operational data and are undergoing testing. **
 
Visible and thermal signatures of the Space-X EchoStar 23 (http://www.spacex.com/news/2017/03/16/echostar-xxiii-mission) rocket launch were seen with GOES-16 imagery on 16 March 2017. The set of 3 images above consists of 5-minute CONUS sector scans at 05:54:33 UTC (about 5 minutes before launch), 05:59:33 UTC (around launch time) and 06:04:33 UTC (about 5 minutes after launch). The 05:59:33 UTC image was actually scanning the NASA Kennedy Space Center (station identifier KXMR)  area at 06:00:38 UTC, just after the 06:00 UTC launch time. A faint bright glow of the rocket booster was seen on the 0.5-km resolution Visible (0.64 µm (http://www.goes-r.gov/education/docs/ABI-bands-FS/ABI%20Fact%20Sheet%20Band%202.pdf)) image; the 1-km resolution Near-Infrared (1.61 µm (http://www.goes-r.gov/education/docs/ABI-bands-FS/ABI_Band%205_snow-ice_factsheet_FINAL.pdf)) rocket signature was much brighter, because this spectral band senses radiation from both visible and infrared portions of the electromagnetic radiation spectrum (which of the two was a stronger contributor to the bright signal is difficult to determine); the 2-km resolution Shortwave Infrared (3.9 µm (http://www.goes-r.gov/education/docs/ABI-bands-FS/ABIBand7ShortwaveWindowFINAL.pdf)) image displayed a warm (dark black enhancement) "hot spot", although it was not exceptionally warm (with a 306.8 K maximum brightness temperature).

Спойлер

A "warm signal" was also observed on the three GOES-16 ABI (http://www.goes-r.gov/spacesegment/abi.html) Water Vapor bands: Lower-Level (7.3 µm (http://www.goes-r.gov/education/docs/ABI-bands-FS/ABIBand10_LowerLevel_WV-IR_FINAL.pdf)), Mid-Level (6.9 µm (http://www.goes-r.gov/education/docs/ABI-bands-FS/ABIBand9_MidLevelWV_IR_FINAL.pdf)) and Upper-Level (6.2 µm (http://www.goes-r.gov/education/docs/ABI-bands-FS/ABIBand8UpperLevelWVFINAL.pdf)), as shown below. While water vapor is certainly a by-product of rocket booster combustion, it is important to remember that the Water Vapor bands are first and foremost Infrared bands that sense the brightness temperature of a layer of moisture (which can vary in both altitude and depth, depending on the temperature/moisture profile of the atmosphere and/or the satellite viewing angle). In this case, the atmosphere was relatively dry over the region, with little moisture aloft to attenuate the rocket signature — shifting the roughly-corresponding GOES-13 Sounder (had the GOES-13 Sounder instrument been operational (http://cimss.ssec.wisc.edu/goes/blog/?s=GOES-13+Sounderhttp://cimss.ssec.wisc.edu/goes/blog/?s=GOES-13+Sounder))  water vapor weighting functions (http://cimss.ssec.wisc.edu/goes/blog/wp-content/uploads/2017/03/170316_00utc_kxmr_wv_wf.jpeg) (available from this site (http://cimss.ssec.wisc.edu/goes/wf/)) to lower altitudes. However, moisture considerations aside, the rocket signature seen on the 05:59:33 UTC water vapor imagery was primarily a thermal anomaly.

Two communications satellites launched from Cape Canaveral in March aboard Falcon 9 rockets, including a broadcasting craft that lifted off on SpaceX's first re-flown booster, have entered commercial service, according to their owners.

The EchoStar 23 satellite launched March 16 from pad 39A at NASA's Kennedy Space Center in Florida is now in service providing direct-to-home broadcasting of television channels to viewers in Brazil, Colorado-based EchoStar Corp. said May 10 in a quarterly earnings report.

Спойлер

Since its deployment from the Falcon 9 rocket's upper stage, EchoStar 23 fired an on-board engine several times to raise its orbit to geostationary altitude, a regime around 22,300 miles (35,800 kilometers) above Earth's equator, wh ere it orbits in lockstep with the planet's rotation. The spacecraft also extended its power-generating solar panels and communications antennas.

Manufactured by Space Systems/Loral in Palo Alto, California, EchoStar 23 entered service at 45 degrees west longitude, wh ere ultra-efficient plasma thrusters will maintain its position over a planned 15-year operational lifetime.

Based on the SSL 1300 satellite bus, EchoStar 23 was ordered by EchoStar Satellite Services in 2014 and is based on the spacecraft chassis originally built for the CMBStar mobile communications station, a venture into the Chinese market led by EchoStar and canceled in 2008.

The tri-band EchoStar 23 satellite is designed with flexibility, according to EchoStar, with the ability to carry out multiple types of missions. Its communications payload includes Ku-band, Ka-band and S-band transponders.

The craft was originally supposed to launch by the end of 2016, in time to meet a licensing deadline from ANATEL, the Brazilian communications regulatory agency, that requires EchoStar 23 be in service by the end of June.

EchoStar says it has now met that deadline for the Ku-band spectrum, which the company intends to use for television broadcast services in Brazil. The operator has sought an extension on the Ka-band and S-band deadlines, "which may or may not be granted," EchoStar said in the May 10 quarterly earnings report.

The company said it is still exploring options to use its Ka-band and S-band spectrum rights by the regulatory deadline in mid-2017.
