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

Two days after lifting off from Florida’s Space Coast, a Dragon cargo capsule packed with more than 6,400 pounds of research experiments and crew supplies arrived at the International Space Station on Wednesday. Astronaut Jack Fischer used the station’s robotic arm to grapple the supply ship at 6:52 a.m. EDT (1052 GMT).

Russian officials postponed the planned launch of a Proton rocket with an X-ray astronomy satellite Friday until no earlier than July 12 resolve a problem with an inadvertently drained battery on the vehicle.

A Russian Proton rocket boosted a Turkish telecommunications satellite into space Friday after a blazing liftoff from Kazakhstan, and a Breeze M upper stage injected the 5.4-ton broadcasting craft into an orbit ranging more than 20,000 miles above Earth nine hours later.
