SpaceX is targeting Saturday, February 22 for a Falcon 9 launch of 22 Starlink satellites to low-Earth orbit from Space Launch Complex 4 East (SLC-4E) at Vandenberg Space Force Base in California. Liftoff is targeted for 3:43 p.m. PT, with backup opportunities available until 5:10 p.m. PT. If needed, additional launch opportunities are also available on Sunday, February 23 starting 2:10 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 11th flight for the first stage booster supporting this mission, which previously launched USSF-62, OneWeb Launch 20, and eight 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.

There is the possibility that residents of Santa Barbara, San Luis Obispo, and Ventura counties may hear one or more sonic booms during the launch, but what residents experience will depend on weather and other conditions...

наклонение орбиты 15й оболочки - 70грд

Поскольку оболочек VLEO 70 градусов нет (только ~97), их следует направить на расстояние ~470 км, ожидая одобрения регулирующих органов для постоянного нахождения.

Поскольку оболочек VLEO 70 градусов нет

Запамятовал, что такое VLEO?
В 2023 году 2-ая оболочка запущена на 70 градусов.

P.S. Нашёл: VLEO (Very low Earth orbit) – это орбиты на высоте до 400 км.
В текущем запуске же нет DTC-ов. В чём проблема работать "как все" на 500 км?
