Video: Falcon 9 launch of DSCOVR

Russia launched a military communications satellite Wednesday, sending a data relay and broadcasting station to an orbit more than 22,000 miles above the equator aboard a Proton rocket and a Breeze M upper stage.

A massive radio broadcasting satellite for SiriusXM is set for liftoff Friday on top of a Falcon 9 rocket, punctuating a busy week for SpaceX that included the debut of a new-generation cargo ship for the International Space Station and a spectacular atmospheric test flight of a prototype rocket over South Texas.

SpaceX’s first Falcon Heavy rocket is expected to roll out to pad 39A at NASA’s Kennedy Space Center for the first time next month for a hold-down firing of its 27 Merlin main engines, but the mega-rocket’s inaugural test launch will slip into January, officials confirmed Tuesday.
