Shuttle managers announced Saturday morning they needed an extra day to complete repairs on a leaky pressurization system on Discovery, pushing back the launch to Wednesday afternoon. NASA on Friday delayed the launch one day in order to replace leaking helium and nitrogen seals in an OMS pod on the order. Saturday morning managers concluded they needed additional time to complete the work and perform pressurization tests, hence they decided to push the launch back an additional day. Launch is now scheduled for 3:52 pm EDT (1952 GMT) Wednesday, with a 70-percent chance of acceptable weather.
