Live coverage: Delta 2 launches

A previously-flown SpaceX Falcon 9 rocket booster conducted a test-firing Monday at NASA’s Kennedy Space Center in Florida, ahead of a planned launch Oct. 7 with an Airbus-built communications satellite made for SES and EchoStar.

NASA and Northrop Grumman are expected to base the launch of an air-dropped Pegasus rocket with a NASA science satellite from Cape Canaveral later this year, after originally trying to get the mission into space from a remote island in the middle of the Pacific Ocean.

Resuming space launches from the U.S. Western Range at Vandenberg Air Force Base in California after a half-year infrastructure outage, an Atlas 5 rocket will boost a commercial Earth-imaging bird into orbit on Friday.
