Live coverage: ExoMars orbiter steers into orbit around Mars, lander’s fate TBD

SpaceX technicians at Cape Canaveral are readying for the first launch of an upgraded Falcon 9 rocket configuration next week, a mission that will debut changes to make the launcher safer for astronauts and make it easier — and less expensive — for the company to reuse first stage boosters.

SpaceX’s first launch since August took off Saturday from Vandenberg Air Force Base in California. A Falcon 9 rocket deployed the first 10 next-generation Iridium communications satellites, part of a $3 billion upgrade to the company’s space network. Liftoff occurred at 9:54 a.m. PST (12:54 p.m. EST; 1754 GMT), and the Falcon 9’s first stage landed on a barge in the Pacific a few minutes later.

Blasting into space atop an Ariane 5 launcher, two communications satellites started missions Sunday to beam broadband services to ships, airplanes and offshore oil rigs for a commercial Norwegian operator and relay signals for the Italian and French armed forces.
