This communications mission was pushed forward in SpaceX’s calendar after the company had to pull out of its Starlink 10-2 mission, which saw weather clearing followed by a pre-liftoff abort last Friday. With the National Oceanic and Atmospheric Administration’s GOES U satellite heading to SpaceX’s other pad, Pad 39A at the Kennedy Space Center, SpaceX can only use Space Launch Complex 40, and therefore decided to move that rocket aside. troubled Falcon 9.
The Astra 1P/SES-24 payload is a communications satellite for a partnership of SES and Astra, which are European communications organizations. The Ku-band geostationary satellite, which was developed by Thales Alenia Space, will provide satellite television service to Germany, France and Spain. According to the SES website, Astra satellites have been providing TV and radio to Germany since 1988.
