Live coverage: Ariane 5 blasts off with two Intelsat satellites

NASA plans to shelve a robotic demonstration mission to refuel an aging Landsat Earth-imaging observatory and join forces with the private sector and a U.S. military research and development agency in a public-private partnership to commercialize satellite servicing technologies, according to language in the White House’s budget request released Tuesday.

Watch this replay of Monday’s liftoff of a SpaceX Falcon 9 rocket from Vandenberg Air Force Base in California, followed by touchdown of the booster’s first stage on a drone ship in the Pacific Ocean.

The long queue of satellites waiting on launches aboard SpaceX’s Falcon rockets — a backlog the company says is worth $7 billion — will stay grounded while investigators determine what caused a Falcon 9 booster to disintegrate after liftoff Sunday.
