SCRUB!
0802 GMT (4:02 a.m. EDT)
SCRUB! Today's launch attempt has been stopped by the fuel cell problem. Another try could come as early as Thursday, with a target liftoff time of 12:03 p.m. EDT. http://www.spaceflightnow.com/shuttl...15/status.html -- -------------- Jacques :-) www.spacepatches.nl |

Well, a spike could mean lots of things. Debris in the coolant, a dodgy
drive or bearing, cavitations implying a leak,. I suppose the cells are under the cargo in the payload bay, which would mean a lot of work to get to them.

Atlantis has been sitting in the OPF for years getting looked at closely by the maintenance technicians. They've had plenty of time to get things fixed up, checked, tested. The scrubs due to glitches on the pad at last minute are not "common" but not uncommon either. Makes me wonder if the testing done in the OPF is really thorough or not. Could they stage a "countdown" in the OPF all the way down to engine ignition (but stopping short of it, of course) to test all of the orbiter's systems , including having the payload bay doors closed so that any escaping gas from a poor seal would be detected by the gas detectors ? Or are there too many systems that can only be turned on once and require maintenance once they've been activated before they can be activated again ? |

I suppose the cells are under the cargo in the payload bay, which would mean a lot of work to get to them. There was another space mission that had a defective oxygen tank, and they knew it wasn't up to spec but they decided to fly with it anyway. Bad move, that was Apollo 13. Only good thing was that it decided to blow just before they were going to use the LM to land on the Moon, not afterwards. Of course if it never blew... My point is that you don't want to launch a space mission if you know of a defect in your spacecraft. |
