NASA's Space Shuttle Discovery was supposed to launch tonight for a two-week mission, linking up with the International Space Station, but the launch has been delayed due to yet another technical problem.

Engineers discovered a fuel leak, as the orbiter was being refueled with hydrogen fuel. The shuttle mission has already been delayed for two weeks, while problems with the flow control valves were being assessed and repaired, although NASA has said this is an unrelated problem. The AP is reporting that officials are aiming for a Thursday night launch provided that the problems can be solved quickly, and officials are meeting later today to discuss options.


This mission was planned to deliver the Integrated Truss Segment, to expand the size of the station, as well as new batteries and solar panels, which will help to accommodate the larger crew compliment that is planned for later this year.
