Watch the Falcon 9 light its engines for a static test fire (members only)

A Chinese Long March 2D rocket carried four “technology experiment satellites” into orbit Wednesday from the Xichang space center in southwestern China, according to the country’s state-run media.

The Sunday evening launch was the first of two in a period of just over five hours. Liftoff from Cape Canaveral Space Force Station took place at 7:05 p.m. EDT (2305 UTC).

SpaceX is gearing up for the first commercial launch of its powerful Falcon Heavy rocket as soon as early April with a communications satellite for Arabsat, and the U.S. Air Force hopes the two side boosters from the Arabsat mission can be safely landed and reused for the military’s first Falcon Heavy mission this summer, an exercise officials said will help certify previously-flown hardware for future national security launches.
