Watch live: SpaceX to launch rocket and attempt landing on ship
Elon Musk’s SpaceX has lifted off from Vandenberg Air Force Base, en route to attempting to land the rocket’s first stage on a ship off the Southern California coast.
Neither of the two previous attempts to stick a sea landing has succeeded, although the company brought a Falcon rocket stage back to terra firma at Cape Canaveral, Fla., on Dec. 21 in what many hailed as an engineering feat.
