SpaceX is targeting Sunday, July 28 for a Falcon 9 launch of 21 Starlink satellites, including 13 with Direct to Cell capabilities, to low-Earth orbit from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California. Liftoff is targeted for 12:24 a.m. PT, with backup opportunities available until 4:14 a.m. PT. If needed, additional opportunities are available on Monday, July 29 starting at 12:53 a.m. ET.

A live webcast of this mission will begin about 15 minutes prior to liftoff, which you can watch here and on X @SpaceX.

This is the 17th flight for the first stage booster supporting this mission, which previously launched NROL-87, NROL-85, SARah-1, SWOT, Transporter-8, Transporter-9, NROL-146, and nine Starlink missions. Following stage separation, the first stage will land on the Of Course I Still Love You droneship, which will be stationed in the Pacific Ocean...

Не сразу заметил особенность: в запуске на один спутник больше, чем в предыдущих с  Direct to Cell.
Всего - 21.
