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

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.

After calling a hold less than a minute before liftoff Friday, SpaceX launched the Maxar-built SXM 7 radio broadcasting satellite for SiriusXM Sunday. A Falcon 9 rocket lifted off from pad 40 at Cape Canaveral at 12:30 p.m. EST (1730 GMT).

Six years after launching for the first time, a Russian Angara A5 heavy-lift rocket took off on its second test flight Monday and successfully delivered a dummy payload into orbit.
