STS-69 SCRUB ANNOUNCEMENT

August 31, 1995
5:30 a.m.

Mission managers scrubbed today's scheduled launch of Space Shuttle
Endeavour and mission STS-69 due to the failure of one of the orbiter's
three fuel cells.  The scrub was called at about 3:30 a.m., prior to
commencing tanking operations, during normal fuel cell activation.
Fuel cells provide electricity to the orbiter while in space.  Mission
rules state that all three fuel cells must be up and operational prior
to launch.  Managers have indicated the fuel cell will be removed and
replaced, effectively postponing the launch about a week.

A briefing is being planned for about 10 a.m. EDT today to discuss the
problem and likely turn-around timelines.  This briefing will be
broadcast on NASA TV.
