Live coverage: Space station crew back on Earth

Rocket Lab launched seven satellites Monday from New Zealand on a rideshare mission serving the U.S. and Australian militaries and space services startups. A spacecraft developed in-house by Rocket Lab was also aboard to prove out technologies for a NASA moon mission launching later this year.

Finally on the cusp of launching people to the edge of space, Blue Origin plans to use a suborbital test flight of its New Shepard booster and crew capsule Wednesday to rehearse boarding and recovery procedures for future missions with paying passengers.

An Ariane 5 rocket launched Tuesday with the Arabsat 6B and GSAT 15 communications satellites to broadcast television across the Middle East, North Africa and Central Asia and link India with telecom and navigation services. Liftoff from Kourou, French Guiana, occurred at 2134 GMT (4:34 p.m. EST).
