Mission Details
OneWeb #20
The 20th flight dedicated to the OneWeb high-speed Internet constellation. The initial constellation consists of 648 satellites. Later, the constellation could be expanded to more than 900 satellites depending on demand. OneWeb is expected to begin customer demonstrations in 2022, then provide a global, 24-hour service in 2022/2023.
Each satellite in the constellation weighs 147.7 kg. They are powered by Russian ion engines, manufactured by OKB-Fakel, and have two solar panels for their power supply. The first generation of satellites, operating on a quasi-polar orbit (1 200 km x 86.4°), cannot perform inter-satellite communication, and can only be used near a ground relay station.
Payloads: 20  Polar Orbit

Location
SLC-4E, Vandenberg SFB, California, USA

SpaceX is targeting Sunday, September 29 at 11:54 p.m. PT for Falcon 9's launch of the OneWeb Launch 20 mission to low-Earth orbit from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California. If needed, there is a backup opportunity available on Monday, September 30 at 11:49 p.m. PT.

A live webcast of this mission will begin about five minutes prior to liftoff, which you can watch here and on X @SpaceX. You can also watch the webcast on the new X TV app.

This is the seventh flight of the first stage booster supporting this mission, which previously launched USSF-62 and five Starlink missions. Following stage separation, the first stage will land on Landing Zone 4 (LZ-4) at Vandenberg Space Force Base...

мнение:

Судя по всему, специалисты компании SpaceX уже разобрались с причинами нештатного свода с орбиты 2-й ступени РН Falcon-9, использовавшейся в минувшую субботу для запуска миссии Crew-9. Как сообщалось вскоре после запуска, возникшая в двигательной установке аномалия привела к тому, что ступень затонула в Тихом океане вне запланированного квадрата. В SpaceX тогда заявили, что пуски приостановлены до вяснения всех причин происшедшего.
И действительно, запланированный на 30 сентября пуск был отложен до 2 октября. Однако, сегодня его передвинули в графике влево, на 1 октября. Что явно говорит об обнаружении причин неполадок в ДУ 2-й ракеты. Вместе с тем, о характере аномалии в компании не спешат говорить.

  За что так?

[Pirat5]

или не обнаружили причину...

[zandr]

Но Старлинки из Флориды - на 5-ое (свиг на 1 день), Хера и Клипер - при своих сроках, а сабж - на неделю с гаком!

[zandr]

О, как: запланировали перед ним 4-го запуск Starlink Group 11-2.

[zandr]

Всё отложено.
FAA не даёт добро на запуски Фалкона с затоплением второй ступени до окончания расследования её непопадания в заявленные зоны.

[zandr]

Дано добро. Запуски начались.
