SPACE-X ROCKET LAUNCH aborted. “The engine ignition sequence for the SpaceX Falcon 9 rocket started up at the three-second mark Saturday morning, but the onboard computers automatically shut down. So instead of blasting off on a delivery mission to the space station, the rocket stayed on its launch pad amid a plume of engine exhaust. . . . Tuesday is the earliest that SpaceX can try again to send its cargo-laden Dragon capsule to the space station. The California-based company — formally known as Space Exploration Technologies Corp. — is targeting every third day for a launch attempt to save fuel in case of rendezvous problems at the space station.” Well, it is rocket science.
