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

Three Russian military satellites arrived in orbit Wednesday after taking off from the Plesetsk Cosmodrome aboard a Rockot launch vehicle, a decommissioned ballistic missile modified for space applications.

Poor weather in the offshore recovery zone east of Florida forced SpaceX and NASA to delay the departure of an upgraded Cargo Dragon spaceship from International Space Station Monday. The capsule is bringing home several tons of research equipment, specimens, and other equipment.

An Ariane 5 rocket lifted off at 2143 GMT (5:43 p.m. EDT) Thursday from French Guiana with a pair of commercial TV broadcasting satellites for AT&T and Eutelsat.
