Orbital Sciences' third resupply mission to the International Space Station ended in disaster earlier today as the rocket exploded shortly after liftoff in Virginia. Fortunately, the mission was only carrying cargo and not astronauts. Expect an extensive inquiry. Stay tuned.
Update: I corrected my posting to note this was Orbital Science's third planned mission to the ISS. In terms of the accident, the company's website stated:
Orbital Sciences Corporation confirms that today’s Antares rocket launch from NASA’s Wallops Flight Facility was not successful. Shortly after lift-off from the Mid-Atlantic Regional Spaceport Pad 0A at 6:22 p.m. (EDT), the vehicle suffered a catastrophic failure. According to NASA’s emergency operations officials, there were no casualties and property damage was limited to the south end of Wallops Island. Orbital has formed an anomaly investigation board, which will work in close coordination with all appropriate government agencies, to determine the cause of today’s mishap.
This may mean more work for SpaceX to pick up the slack.
