MMT Gives "Go" For Thursday Launch Try, Eyes Weather

After looking deeply into an issue with a main engine controller on space shuttle Discovery, the Prelaunch Mission Management Team is confident the issue has been resolved, said Mike Moses, chair of the MMT. The team therefore gave a unanimous "go" for Discovery's launch Thursday at . That means the countdown will proceed through the night, including the retraction of the Rotating Service Structure from around the shuttle.

"From the vehicle perspective, we're ready to go," Moses said.

However, the weather forecast calls for a 20 percent chance of acceptable conditions, with the concerns being low clouds and rain within 20 miles of the Shuttle Landing Facility at launch time. The MMT will meet at Thursday to consider the forecast and will decide then whether to fill the shuttle's huge external fuel tank for the launch.

"The weather still looks pretty bad for tomorrow," Moses said. "There's a chance we'll decide not to spend one of our (launch) opportunities."
