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.

Technicians working in the jungle of French Guiana have installed four new European Galileo navigation satellites on top of their Ariane 5 launcher, and filled the rocket’s upper stage with storable liquid propellants for liftoff Tuesday.

A European Ariane 5 rocket is scheduled for blastoff  Tuesday from a jungle launch pad in South America with two geostationary telecom payloads — one owned by a Saudi Arabian operator and built in Colorado by Lockheed Martin, and another for India’s space agency.
