A SpaceX Falcon 9 rocket arrived at launch pad 39A on Florida’s Space Coast on Sunday, a day before liftoff with a powerhouse Inmarsat communications satellite designed to spread broadband beams connecting airline passengers, maritime crews and U.S. and international military units with Internet and data services.

The Cygnus commercial logistics vehicle departed the International Space Station Sunday morning for a week-long free-flight filled with autonomous science tasks before re-entry.

The nuclear power generator for NASA’s Perseverance rover has been installed on the spacecraft atop an Atlas 5 rocket at Cape Canaveral, and mission managers gave a green light Wednesday to continue preparations for the rover’s July 30 launch toward Mars.
