Live coverage: Proton soars into space with Inmarsat satellite

Live coverage of the countdown and launch of a SpaceX Falcon 9 rocket from NASA’s Kennedy Space Center with the Koreasat 5A communications satellite. Including a live view of the launch pad (members only).

SpaceX’s launch of a cluster of communications satellites for Orbcomm, set for as soon as next weekend, holds the headlines, but the company’s Falcon 9 rocket could fly at least four times in the next two months, assuming smooth launch campaigns and no glitches.

An Ariane 5 rocket launched from French Guiana at 2150 GMT (5:50 p.m. EDT) Thursday with a pair of European-built communications satellites for the Brazilian government and KTsat, a South Korean telecom operator. Liftoff was delayed more than one hour to resolve a problem with ground equipment.
