DiscoveryÂ’s crew is spending what should be its last night in space, with an early morning landing planned Monday at NASAÂ’s Kennedy Space Center in Florida, concluding a voyage of 5 35 million miles

In preparation for tomorrow’s 3:47 a m CDT landing, Commander Eileen Collins, Pilot Jim Kelly and Mission Specialist Steve Robinson activated one of three hydraulic systems on Discovery and tested all of its aerosurfaces and steering jets The rest of the crew – Andy Thomas, Soichi Noguchi, Wendy Lawrence and Charlie Camarda – completed packing up gear and hardware The seven-member crew took a moment early this morning to talk with CBS, CNN, Fox, NBC and ABC, discussing their mission and upcoming return to Earth

Discovery has two opportunities to land at the Kennedy Space Center on Monday The first begins with a 3 minute, 7 second deorbit burn of the Orbital Maneuvering System engines at 2:40 a m , followed by landing at 3:47 a m CDT

In the event weather prevents landing on that first opportunity, a second is available, with deorbit burn at 4:15 a m resulting in a 5:22 a m CDT landing It will be the 15th night landing in Florida and 20th overall for the Space Shuttle Program

Weather forecasters predict favorable conditions with light and variable winds and a slight chance of showers in the vicinity of the three-mile-long landing strip The backup site at CaliforniaÂ’s Edwards Air Force Base was not activated for Monday
