SpaceX is targeting Saturday, September 10 for a Falcon 9 launch of 34 Starlink satellites and AST SpaceMobile's BlueWalker 3 satellite to low-Earth orbit from Launch Complex 39A (LC-39A) at Kennedy Space Center in Florida. The instantaneous launch window is at 9:10 p.m. ET, or 01:10 UTC on September 11, and a backup opportunity is available on Sunday, September 11 at 8:48 p.m. ET, or 00:48 UTC on September 12.
The first stage booster supporting this mission previously launched Crew Demo-2, ANASIS-II, CRS-21, Transporter-1, Transporter-3, and eight Starlink missions. Following stage separation, the first stage will land on the A Shortfall of Gravitas droneship, which will be stationed in the Atlantic Ocean. This will also be Falcon 9's first five-burn mission. = B1058.14!

всех удивили!

Elon Musk:
— Одна из самых сложных миссий в нашей истории.
Дело в том, что в рамках миссии вторая ступень Falcon 9 осуществит целых пять включений двигателя Merlin Vac: два - для выхода на орбиту развёртывания BlueWalker-3, ещё два - перед отделением спутников Starlink, и заключительное - для схода с орбиты.
🏆 Но, пожалуй, главным достижением SpaceX в предстоящем запуске станет новый рекорд многоразовости первой ступени. Историческая первая ступень Falcon 9 B1058 претендует на звание первого ускорителя, преодолевшего отметку в 14 полётов.
