Video: Liftoff of Atlas 5 on NROL-55

A Chinese television broadcasting satellite lifted off Saturday aboard a Long March 3B booster, the 300th orbital launch by the country’s Long March rocket family since 1970.

A recent federal regulatory filing by SpaceX suggests the company may attempt to return a Falcon 9 rocket booster to Vandenberg Air Force Base in California for the first time later this year.

A Blagovest communications spacecraft lifted off Monday aboard a Proton rocket to complete a network of four relay satellites in geostationary orbit for the Russian military. The Proton rocket’s Breeze M upper stage successfully delivered the Blagovest spacecraft to its intended orbit nine hours later.
