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

Set to fly in its most powerful configuration with five solid rocket boosters, a United Launch Alliance Atlas 5 rocket rolled out to Cape Canaveral’s Complex 41 launch pad Tuesday in preparation for a planned blastoff two days later with a U.S. military communications satellite.

SpaceX launched a Falcon 9 rocket from California’s Central Coast at 10:42:18 a.m. PST (1:42:18 p.m. EST; 1842:18 GMT) Sunday with the Jason 3 oceanography satellite. A secondary objective of the mission to recover the first stage on a barge in the Pacific Ocean failed.

An Ariane 5 rocket emerged from its vertical assembly building Monday and rolled along dual rail tracks for a 1.7-mile (2.7-kilometer) journey to its launch pad at the Guiana Space Center on the northern coastline of South America, moving into position for blastoff Wednesday with four Galileo navigation satellites.
