SpaceX Will Try Again to Launch Satellite and Land a Rocket Today

SpaceX is hoping the fourth time's the charm with its bid today (March 4) to launch a commercial satellite into space and then return its rocket booster to Earth to land on a barge. The Hawthorne, California-based SpaceX is targeting a 6:35 p.m. EST (2335 GMT) blastoff from a pad at Florida's Cape Canaveral Air Force Station for its unmanned Falcon 9 rocket. You can watch a webcast of the launch live on Space.com, courtesy of SpaceX, which is offering two different video streams of the event.
