Live coverage: 400th Proton rocket takes off with Russian satellite

A United Launch Alliance Atlas 5 rocket fitted with five powerful solid-fueled boosters has lifted off from a seaside launch complex at Cape Canaveral with the U.S. Navy’s third Mobile User Objective System communications satellite.

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.

A veteran cosmonaut, a former Japanese 767 airline pilot and a NASA astronaut with a Ph.D. in cancer biology are making final preparations for launch July 6 on a two-day flight to the International Space Station. It will be the first flight in an upgraded Soyuz ferry craft with improved, more redundant navigation, communications and computer equipment.
