At T-7 seconds today, Discovery's computer started the
SSME ignition sequence, in which all engines are turned
on at 120 milllisecond intervals.  Two made it, but
the computers detected a fuel valve failure in the Number
1 engine and directed it not to fire; they also commanded
the other two to shut down.  Thus, the countdown was
stopped 4 seconds before the SRB's were to have ignited.

The engine with the trouble was taken from Challenger
earlier in the month, but the fuel valve was apparently
one of Discovery's.  No word has been given on what sort
of delay to expect.  It could be several days or several
weeks.  The crew has been placed on leave status.
