Now you see me...now you don't! More #O3bmPOWER satellites inside the fairing and getting ready for launch at the end of this week.

The second pair of O3b mPOWER satellites have been enclosed inside the Falcon 9 payload fairing ahead of their launch, which is currently scheduled for April 28th, 21:12 UTC. Combined, the satellites weigh ~4.100kg in launch configuration.

SpaceX is targeting Friday, April 28 for a Falcon 9 launch of the SES O3b mPOWER mission to medium-Earth orbit from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station in Florida. The 88-minute launch window opens at 5:12 p.m. ET (21:12 UTC). If needed, a backup opportunity is available Saturday, April 29 with the same window.

The first stage booster supporting this mission previously launched Crew-6. Following stage separation, the first stage will land on the Just Read the Instructions droneship, which will be stationed in the Atlantic Ocean.

A live webcast of this mission will begin about 15 minutes prior to liftoff...

Скорее всего, но однажды недавно у них уже был запуск при (ЕМНИП) 20% благоприятствовании.
