Live coverage: Proton soars into space with Inmarsat satellite

Japan’s Astro-H mission, an X-ray astronomy observatory designed to shed light on black holes and the unseen structure of the universe, lifted off aboard an H-2A rocket from the Tanegashima Space Center at 0845 GMT (3:45 a.m. EST) Wednesday.

SpaceX conducted the first hold-down firing of an upgraded version of the Falcon 9 rocket Friday at NASA’s Kennedy Space Center in Florida, in preparation for launch next week with Bangladesh’s first communications satellite.

SpaceX is targeting launches March 6 and March 11 for its next two missions after swapping an upper stage for its next Falcon 9 rocket with another stage already being readied for liftoff at Cape Canaveral.
