Launch Delayed by Fuel Cell Problem

Launch Delayed by Fuel Cell Problem
The launch of Space Shuttle Atlantis was postponed today for at least 24 hours due to a problem that occurred Tuesday night during the activation of one of the shuttle's three electricity-producing fuel cells. A spike and drop in voltage was noticed on fuel cell number one. Troubleshooting is ongoing, and the problem has been isolated to a coolant pump that helps cool the fuel cell system.The Mission Management Team is scheduled to meet at 12p.m. CDT today to review more data and assess the problem, and a news conference will follow.
