http://www.spaceflightnow.com/falcon9/003/status.html http://www.spaceflightnow.com/falcon9/003/status.html 1040 GMT (6:40 a.m. EDT) Gwynne Shotwell, president of SpaceX, says technicians will inspect Engine No. 5 on the Falcon 9's first stage beginning at around 12 p.m. EDT (1600 GMT). Further data analysis of readings from the engine during the ignition prompted SpaceX to order hands-on inspections before clearing the rocket for liftoff. The next launch opportunity is still Tuesday at 3:44 a.m. EDT (0744 GMT), but that is pending the outcome of today's inspection. Shotwell said the abort was triggered one-half second before liftoff after all nine engines were ignited. Alan Lindenmoyer, NASA's commercial crew and cargo manager, said there should be another launch opportunity May 23 at 3:22 a.m. EDT (0722 GMT). 0940 GMT (5:40 a.m. EDT) The target launch time for Tuesday is 3:44:34 a.m. EDT (0744:34 GMT). 0926 GMT (5:26 a.m. EDT) The rocket is being drained of propellant as the launch team backs out of this morning's countdown following an abort moments before liftoff at 4:55 a.m. EDT (0855 GMT). 0915 GMT (5:15 a.m. EDT) NASA plans a post-scrub news conference at 6:30 a.m. EDT (1030 GMT). We'll carry it live. 0905 GMT (5:05 a.m. EDT) The strongback has been returned to a position next to the Falcon 9. 0901 GMT (5:01 a.m. EDT) SpaceX reports the problem triggering the abort was a high chamber pressure reading on Engine No. 5 of the first stage. Aborts are common in Falcon 9 countdowns when computers recognize a limit out of a predefined range. Sometimes the fix is as simple as adjusting the acceptable range in the computer, but with a one-second launch window this morning, there will no opportunity to resolve the issue today. 0858 GMT (4:58 a.m. EDT) The launch team is safing the rocket and Dragon spacecraft after this morning's abort. The next launch opportunity is Tuesday morning at 3:44 a.m. EDT (0744 GMT), assuming whatever issue caused the abort is resolved in time. 0856 GMT (4:56 a.m. EDT) It's not clear what caused the abort just before liftoff, but this will mean Falcon 9 will not launch today. The rocket had a near-instantaneous launch window in which it could fly today. 0855 GMT (4:55 a.m. EDT) ABORT. The ignition sequence started, but there was a countdown cutoff before launch.

  I think it's pretty amazing that this kind of thing can be co-ordinated down to a 1 second launch window.

    It's less that is _can_ and more that it _has to_ in order to be optimal. The launch window pretty much guarantees that if the rocket launches, and stays on a course that is designed to get it outside of earth's atmosphere using as little fuel as possible, it will meet up with the orbiting space station "by chance". Launching outside of this window means that it would have to spend fuel to realign itself and go find the space station on it's own.

      Probably one of their many hacks at getting the launch cost down as much as possible.
