Discovery Undocks From Space Station, Set to Land Wednesday


*Discovery Undocks From Space Station, Set to Land Wednesday*
6 November 2007

The crew will spend today preparing for landing. Discovery’s first 
landing opportunity is at 1:02 p.m. EST Wednesday at Kennedy Space 
Center, Fla. Weather forecasters predict favorable landing conditions 
once a cold front passes through late Tuesday night. The backup landing 
sites at Edwards Air Force Base, Calif., and White Sands Space Harbor, 
N.M., will not be considered Wednesday.

Space shuttle Discovery’s crew left the International Space Station 
Monday morning after almost 11 days of joint operations with the 
Expedition 16 crew. The shuttle undocked from the station at 5:32 a.m. 
as they flew over the South Pacific.

STS-120 Pilot George Zamka backed the orbiter about 400 feet from the 
station and performed a fly-around to allow crew members to collect 
video and imagery of the station in its new configuration. He completed 
the final separation engine burn at 7:15 a.m.

The shuttle crew members used the shuttle robot arm and the 50-foot long 
Orbiter Boom Sensor System to conduct a late inspection of the thermal 
protection system.

During its stay at the station, which began Oct. 25, the STS-120 crew 
continued the on-orbit construction of the station with the installation 
of the Harmony Node 2 module and the relocation of the P6 truss.

The crew installed Harmony Oct. 26 and did four spacewalks at the 
station. During the third spacewalk, the crew installed the P6 truss and 
solar array pair in its permanent location outboard of the port truss. 
The fourth spacewalk was changed during the mission so that the crew 
could repair a torn solar array on the P6 truss. Following the 
successful repair work, the crew was able to fully deploy the solar array.

Discovery also delivered a new station crew member, Flight Engineer 
Daniel Tani. He replaced astronaut Clayton Anderson. Anderson arrived at 
the station in June with STS-117.
