Falcon 9 countdown aborted

Running two-and-a-half hours late because of technical problems and a sailboat in the launch danger zone, SpaceX attempted to launch its new Falcon 9 rocket on its maiden flight Friday, but the countdown was interrupted with less than five seconds to go by an unspecified problem.

There was no immediate word from SpaceX on what caused the 1:30 p.m. EDT abort or whether another launch try might be possible before the four-hour launch window closes at 3 p.m.

The company is attempting to provide live coverage with a webcast anchored from SpaceX headquarters in Hawthorne, Calif., but presumably overloaded servers have caused lengthy interruptions and intermittent service throughout the day. No other source of information was provided.

This status report will be updated after launch or as conditions warrant.
