Live coverage: Ariane 5 rocket deploys satellites for Australia, India

The launch from Cape Canaveral of a top secret spy satellite for the U.S. government was aborted at the last moment early Saturday as its United Launch Alliance Delta 4-Heavy rocket ignited three main engines, a dramatic cutoff of the countdown that will delay the mission by at least one week.

A SpaceX Falcon 9 rocket lifted off from Space Launch Complex 4-East at Vandenberg Air Force Base in California at 12:17 p.m. EST (9:17 a.m. PST; 1717 GMT) Saturday with an oceanography satellite jointly developed by U.S. and European space and weather agencies. The rocket’s first stage booster returned to a bullseye landing back at Vandenberg.

SpaceX’s Falcon 9 rocket is set for liftoff from Cape Canaveral on Tuesday, heading due east over the Atlantic Ocean to deliver the Hispasat 30W-6 communications satellite into orbit around 33 minutes later.
