PAO: This is Mission Control. We’re at a Mission Elapsed Time of two days, 11 hours, 55 minutes. The crew has just over six hours remaining in their sleep period... Currently Discovery’s payload bay cameras are once again catching some lightning activity as Discovery passes overhead. On previous nights we’ve seen quite a bit of lightning activity…

Tuesday, October 9, 1990 (Flight Day 4) – Towards the Shores of Ithaca

“No longer now from shore to shore to roam,
Smooth seas and gentle winds invite him home.”


- Homer, “The Odyssey,” Book XIII

IT’S A VERY FINE VEHICLE

Wakeup call – 12:30 a.m. CDT: “Fanfare for the Common Man,” written by Aaron Copland, one of PLT Robert Cabana’s favorites The textbook flew unaltered for a fourth day, a photocopy of the previous ones, except this came as the last full day in space. In addition to SSBUV Earth views, VCS runs and winding up other experiments, the crew had to pack for home and conduct the Flight Control System and Reaction Control System checks of the systems they would need for landing the next day.


PAO: This is Mission Control Houston, at two days, 22 hours, 26 minutes. All quiet here in the Flight Control Room as the crew aboard Discovery continues to work through their Flight Control System checkout. That’s a checkout to verify that all Flight Control System aboard Discovery are in good health and ready to support deorbit, entry and landing operations tomorrow. Discovery just about to cross the equator and begin the orbit number 48.

   
The FCS checkout was completed smoothly by 5:39 a.m. CDT. It was normally followed directly by the RCS checkout, firing all the orbiter’s jets to verify their readiness. However, the jet firings were delayed until the afternoon to allow the robot arm to stay deployed, giving extra exposure time for the Intelsat samples.

At 5:53 a.m. CDT, Cabana reported the first actual “failure” with mock seriousness. ”We’ve had the first inflight anomaly, I think. The pin on the bottom side of the galley that the WCS door attaches to has broken off, and we saved it. You can add that to our inflight anomaly log. It’s a very fine vehicle; it’s been flying great.”

At 7:15 a.m. CDT, what the PAO termed “the first real systems failure” occurred. The B heater for an APU fuel line failed to work automatically. “The cause is thought to be a thermostat failure in the heater system… The fix, of course, is just to stay on the A side heaters for the rest of the flight.” And never to fear that redundancy would be lost, the B heaters could be operated manually if the A heaters were lost.
