An Intelsat communications satellite launched last August entered service Sunday, about three months later than planned after a main engine problem forced engineers to position the craft in geostationary orbit using backup low-thrust rocket jets.

A United Launch Alliance Atlas 5 rocket fired into space Thursday from Cape Canaveral with a $1.1 billion U.S. Air Force communications satellite, delivering fresh capacity for the military’s voice, video and data relay networks.

SpaceX and NASA launched a planet-hunting satellite Wednesday from Cape Canaveral, two days after calling off a launch attempt to conduct additional guidance, navigation and control analyses. Liftoff occurred at 6:51 p.m. EDT (2251 GMT), and the first stage of the Falcon 9 rocket successfully landed on a drone ship in the Atlantic Ocean.
