SpaceX's Historic ISS Cargo Ferry Launch Aborted at the Last Second

Just one half-second before liftoff, computers aborted the launch of SpaceX's Falcon 9 rocket early this morning, delaying the dawn of the commercial space age at least until Tuesday. After all nine engines ignited, launch control detected abnormally high pressure inside the center engine and terminated the countdown. The next available launch window for an historic rendezvous with the International Space Station comes early-morning Tuesday, but NASA and SpaceX engineers will first have to inspect the engine and locate the source of the problem.
