SpaceX launched another Falcon 9 rocket at 5:13 this morning, taking more Starlink satellites into orbit, and about 8 minutes after liftoff, the first stage booster completed another successful landing on a barge in the Atlantic Ocean. This morning’s launch could actually be the first two this week. The launch of a satellite for radio service provider, Sirius XM, is set for sometime during a window that opens at 11:10am and closes at 1:10pm on Thursday.
