Video *seems* to show SF for 3.5 seconds, which is one of the SF options (some are longer).

Now to watch the launch date as the @SciGuySpace's NET means ISS considerations are in play. Could push it into March. Welcome to the wonderful world of Visiting Vehicle conflicts.

Я смотрю КК на РН находился. По программе теста он в случае аварии на САС спасался бы?

Да. Они даже судно поддержки вывели в море во время теста, чтобы поднять из воды в этом случае.

Значит, если шатдаун затянется, то DM-1 перенесут на потОм, а следующим будет SpX-17 - но есть ли на него разрешение?

Why does this LEO mission not RTLS? Is wet Dragon-2 so much heavier than Dragon-1?
As far as I know, it's not the weight.
The first stage ascent trajectory of unmanned Dragon-1 is rather steep upwards, which enables the booster to RTLS.
For Dragon 2, the lofted trajectory is not possible because in an in-flight abort scenario, the capsule would fly a very high parabola and re-enter at a very steep angle with high g-loads. To keep the apogee of this parabola lower, and therefore decrease the re-entry g-loads in case of an abort, Crew Dragon is launched on a flatter initial trajectory, accelerating more horizontally, requiring an ASDS landing.
I can't find the source right now, but as I understand it the flight profile for crew is flatter than cargo dragon to minimize G-loads and improve the performance of the escape system if needed. This means the first stage is farther downrange and has more horizontal velocity at MECO than prior launches, and there isn't the margin left for a longer boost back burn to do RTLS.
Dragon 2 will fly a more flatter trajectory compared to Dragon 1, this is done to avoid high g's on reentry in case the capsule has to abort in mid flight, if the trajectory is flatter the capsule will stay higher for more time instead of falling like a rock in case of a more lofted trajectory. On this last case the reentry forces are higher because the capsule encounters the denser parts of the atmosphere faster so drag builds up faster and the decceleration is higher and the crew experiences more g's. This flatter trajectory means the first stage will separate further from the coast than on Dragon 1 missions and that means it may be impossible to come back to land efficiently so instead it lands on the droneship.

НАСА подтвердило перенос испытательного полета корабля Crew Dragon к МКС


ВАШИНГТОН, 6 фев – РИА Новости. НАСА подтвердило перенос первого испытательного полета корабля Crew Dragon к МКС в беспилотном режиме на 2 марта, дополнительное время требуется для тестирования оборудования и подготовки персонала, сообщили РИА Новости в ведомстве.


"Первый демонстрационный полет намечен на 2 марта", - сказал РИА Новости представитель НАСА Дениэл Хуот.


Ранее источник в российской ракетно-космической отрасли рассказал РИА Новости, что новый американский космический корабль Dragon-2 полетит к МКС в беспилотном режиме 2 марта, а не 23 февраля, как планировалось ранее.



В НАСА пояснили, что дополнительное время необходимо для "завершения необходимых испытаний оборудования, завершения анализа со стороны НАСА и партнеров, а также подготовки диспетчеров полета и руководителей миссии".


По обновленному графику, первый испытательный полет принадлежащего компании Boeing корабля Starliner состоится не раньше апреля.


В НАСА подчеркивают, что предстоящие испытания являются проверкой не только оборудования, но и всей команды для предстоящих в будущем пилотируемых полетов.

"НАСА вместе со SpaceX и Boeing работают над тем, чтобы мы были уверены в том, что мы готовы провести испытательные полеты и готовы получить критически важную информацию, которая позволит обеспечить безопасные полеты экипажей, мы всегда учимся в ходе испытаний", - заявила в связи с переносом старта менеджер пилотируемых полетов НАСА Кэти Лейдерс.

Posted Feb 6, 2019 at 11:00 am

NASA and its Commercial Crew Program providers Boeing and SpaceX have agreed to move the target launch dates for the upcoming inaugural test flights of their next generation American spacecraft and rockets that will launch astronauts to the International Space Station.

The agency now is targeting March 2 for launch of SpaceX's Crew Dragon on its uncrewed Demo-1 test flight. Boeing's uncrewed Orbital Flight Test is targeted for launch no earlier than April.

These adjustments allow for completion of necessary hardware testing, data verification, remaining NASA and provider reviews, as well as training of flight controllers and mission managers.

The uncrewed test flights will be the first time commercially-built and operated American spacecraft designed for humans will dock to the space station. The first flights are dress rehearsals for missions with astronauts aboard the vehicles. Commercial crew has continued working toward these historic missions throughout the month of January.

"The uncrewed flight tests are a great dry run for not only our hardware, but for our team to get ready for our crewed flight tests," said Kathy Lueders, Commercial Crew Program manager. "NASA has been working together with SpaceX and Boeing to make sure we are ready to conduct these test flights and get ready to learn critical information that will further help us to fly our crews safely. We always learn from tests."

In January, SpaceX successfully completed a static fire test of its Falcon 9 with Crew Dragon atop the rocket at Kennedy Space Center's Launch Complex 39A in Florida, in preparation for Demo-1.

Boeing's CST-100 Starliner continues to undergo testing in preparation for its Orbital Flight Test, and United Launch Alliance is conducting final processing of the Atlas V rocket that will launch Starliner from Space Launch Complex 41 at Cape Canaveral Air Force Station in Florida.

"There still are many critical steps to complete before launch and while we eagerly are anticipating these launches, we will step through our test flight preparations and readiness reviews," said Lueders. "We are excited about seeing the hardware we have followed through development, integration, and ground testing move into flight."

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 and the space station on systems that meet safety and performance requirements.

To meet NASA's requirements, the commercial providers must demonstrate their systems are ready to begin regular flights to the space station. After the uncrewed flight tests, Boeing and SpaceX will complete a flight test with crew prior to being certified by NASA for crew rotation missions. The following planning dates reflect inputs by the Commercial Crew Program and the two companies and are current as of Feb. 4, 2019.

Test Flight Planning Dates:
SpaceX Demo-1 (uncrewed): March 2, 2019
Boeing Orbital Flight Test (uncrewed): NET April 2019
Boeing Pad Abort Test: NET May 2019
SpaceX In-Flight Abort Test: June 2019
SpaceX Demo-2 (crewed): July 2019
Boeing Crew Flight Test (crewed): NET August 2019

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

Любопытный корабль Crew Dragon: заправка топливом была в конце декабря, два раза вывозили на старт, один раз проверили готовность ДУ САС, зарядили АБ, "пуск" середине марта, если "Боинг" нам не врёт. Сам корабль был доставлен на Кейп Канаверал аж в июле-августе 2018 года. Долгожитель многоразовый!

NASA and commercial crew provider SpaceX are targeting 2:48 a.m. EST Saturday, March 2, for the launch of the Demo-1 uncrewed flight test to the International Space Station. The uncrewed test flights will be the first time a commercially-built and operated American rocket and spacecraft designed for humans will launch to the space station.

Live coverage will begin on NASA Television and the agency's website Friday, Feb. 22 with prelaunch events.

The SpaceX Crew Dragon spacecraft will launch on a Falcon 9 rocket from the historic Launch Complex 39A at NASA's Kennedy Space Center in Florida. About 10 minutes after launch, Crew Dragon will reach its preliminary orbit. It is scheduled to dock to station Sunday, March 3 at 5:55 a.m. EST. The Crew Dragon spacecraft will carry about 400 pounds of crew supplies and equipment to the space station and return some critical research samples to Earth.

The spacecraft will spend about five days attached to the space station. Dragon will remain at the space station until March 8 when the spacecraft will return to Earth. About five hours after Dragon leaves the station, it will conduct its deorbit burn, which lasts up to 10 minutes. It takes about 30 minutes for Dragon to re-enter the Earth's atmosphere and splash down in the Atlantic Ocean.
