CAPE CANAVERAL, Fla -- The unmanned SpaceX rocket launched successfully on Monday morning at 11:15. Today's liftoff was the fourth attempt. Two countdowns were scrubbed and a third was postponed due to technical and weather problems.
This is the first of two SpaceX launches for Obrcomm Inc., a New Jersey-based provider of machine-to-machine networks that track products shipped around the world and monitor the health of heavy machinery.
The 224-foot Falcon 9 rocket is carrying the first six of 17 Orbcomm Generation 2 satellites upgrading the company's existing constellation in low Earth orbit.
SpaceX will try to steer the Falcon 9's first stage to a soft landing in the Atlantic Ocean for recovery by ships, a step toward developing a reusable booster.
