Live coverage: Two satellites lift off aboard Ariane 5

SpaceX successfully launched a Falcon 9 rocket Sunday at 7:21 p.m. PDT (10:21 p.m. EDT; 0221 GMT Monday) with SAOCOM 1A, a radar observation satellite for Argentina, then returned the booster to a landing at Vandenberg Air Force Base, California, for the first time.

Arianespace has postponed this week’s launch of an Ariane 5 rocket with two European communications satellites to replace a faulty fluid connector between the launcher and its mobile launch platform, officials said Tuesday.

SpaceX has delayed the next launch of a Falcon 9 rocket from pad 39A at the Kennedy Space Center until Sunday. The two-stage launcher will carry with another batch of 60 Starlink satellites into orbit.
