Прошу прощения, я наверно пропустил - а чем именно нынешние старлинки отличаются от v1 из 21 года?

ЦитироватьSpaceX is targeting Sunday, February 20 for a Falcon 9 launch of 46 Starlink satellites to low Earth orbit from Space Launch Complex (SLC-40) at Cape Canaveral Space Force Station in Florida. The instantaneous launch window is at 11:13 a.m. EST, or 16:13 UTC, and a backup opportunity is available on Monday, February 21 at 9:32 a.m. EST, or 14:32 UTC.
The first stage booster supporting this mission previously launched Crew Demo-2, ANASIS-II, CRS-21, Transporter-1, Transporter-3, and five Starlink missions. Following stage separation, SpaceX will land Falcon 9's first stage on the A Shortfall of Gravitas droneship, which will be stationed in the Atlantic Ocean. This is the fourth flight for both fairing halves supporting this mission.
A live webcast of this mission will begin about 15 minutes prior to liftoff.

SpaceX confirms the Falcon 9 rocket's stage achieved the expected parking orbit. It will coast halfway around the world before reigniting for an orbit circularization burn.

Deployment of the 46 Starlink satellites is expected at 10:47am EST (1547 GMT).

Орбитальный полёт блока. Отделение спутников около 18:47 мск.

Почему верхушка обтекателя серая? Так уже было? Я знаю недавно стали добавлят металлические панели на самом кончике, но это вроде что-то новенькое.

Вряд ли что-то добавляли

Wow... today's Falcon 9 entry burn started quite late (<60km, >8000km/h), lasted for only 20 seconds, and only scrubbed of 2200km/h of velocity.
SpaceX seems to be pushing boosters to their limits on recent launches...
