Mission managers scrubbed todays scheduled launch of Space Shuttle
Endeavour and mission STS-69 due to the failure of one of the orbiters
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 10:30 a.m. EDT today to discuss the
problem and likely turn-around timelines. This briefing will be broadcast
on NASA TV.
