Engineers have located the source of the problem that
grounded the Discovery for the first time two weeks
ago.  It was a broken microscopic wire on an integrated
circuit in the I/O system of the backup computer.  When
the four main GPC's (general purpose computer) detected
the failure of the backup computer, they decided to
scrub the launch.  The next day, of course, they did
the same thing when the engine valve failed to open.
