CAPE CANAVERAL, Fla. -Shuttle Discovery is dangling from a crane inside the Vehicle Assembly Buildingthis afternoon after workers carefully removed the orbiter from its externalfuel tank and solid rocket boosters this morning.
Discovery is going to fly with a different external fuel tank, which shuttleworkers modified to solve safety concerns about dangerous ice debris and aglitchy fuel valve. Discovery's move off the old tank is expected to take untilevening to complete.
However, the progress of work inside the assembly building continues slightlyahead of schedule. Discovery could be attached to its new external tank andboosters on Monday, one day early. If so, the shuttle could return to Pad 39Bon June 13, also one day early.
Every day counts for the shuttle launch team as NASA works to ready Discoveryfor the first shuttle mission since the Columbia disaster.
Launch day is currently planned for July 13, though the space agency has untilthe end of July to get Discovery off the ground.
The shuttle team continues to have almost two weeks of padding in the scheduleto achieve the July 13 launch.
If Discovery can't fly in July, NASA will have to wait until September becauseof safety constraints that require good lighting on Earth and in space. Thereason is to make sure engineers have the best pictures possible of the shuttleand its redesigned fuel tank. Foam falling off the tank during launch causedthe 2003 shuttle disaster.
