хотя есть интрига запустить в 20й раз В1060, что вместе с В1061 (WorldView) даст тройку таких ступеней.

SpaceX is targeting Wednesday, April 17 for a Falcon 9 launch of 23 Starlink satellites to low-Earth orbit from Launch Complex 39A (LC-39A) at NASA's Kennedy Space Center in Florida. Liftoff is targeted for 5:26 p.m. ET, with backup opportunities available until 9:24 p.m. ET. If needed, additional opportunities are also available on Thursday, April 18 starting at 5:05 p.m. ET.

A live webcast of this mission will begin on X @SpaceX about five minutes prior to liftoff. Watch live.

This is the 12th flight for the first stage booster supporting this mission, which previously launched Crew-5, GPS III Space Vehicle 06, Inmarsat I6-F2, CRS-28, Intelsat G-37, NG-20, and five Starlink missions. Following stage separation, the first stage will land on the Just Read the Instructions droneship, which will be stationed in the Atlantic Ocean...

Картинка посадки ступени не появилась и в твиттере в обычное время. (Видео Пуска - есть.)

SpaceX  @SpaceX
Nominal orbital insertion and first stage landing on the Just Read the Instructions droneship confirmed.

Falcon 9's second stage has one additional burn coming up in ~38 minutes followed ~11 minutes later by satellite deploy

Пишут - ступень на баржу села.

SpaceX  @SpaceX
Payload deploy confirmed, adding 23 @Starlink satellites to the global constellation

Миссия успешна.

(Кадры торможения и посадки первой ступени так и не появились. Вообще трансляция прекратилась с 2:59.)

Говорят, тестировали новый формат стриминга в X/Twitter. Про ограничения выдавалось и у американцев, и у англичан.
Появилась полная ретрансляция в Ютюбе:
