Mission Control Center, Houston, Texas

HOUSTON - Landing preparations are the order of the day for the seven astronauts on space shuttle Discovery, who are planning to conclude a two-week mission with a Wednesday landing at the Kennedy Space Center.

The crew's 1:38 a.m. CST wakeup call was "Space Truckin" by Deep Purple, played for Mission Specialist Clay Anderson, who will wrap up a five-month mission to the International Space Station when Discovery lands. The crew will start routine deorbit preparations and cabin stowage three hours later.

At 4:23 a.m. Commander Pam Melroy, Pilot George Zamka and Mission Specialist and Flight Engineer Stephanie Wilson will power up an auxiliary power unit to conduct a checkout of the orbiter's flight control surfaces. At 5:33 a.m. they start a test firing of each of the shuttle's reaction control system jets.

The shuttle astronauts take a break from packing at 8:43 a.m. to talk about the flight with the Associated Press, Space.com, and the Lincoln (Neb.) Journal Star, before they return to packing. At 1:18 p.m. mission specialists Scott Parazynski and Doug Wheelock will set up a recumbent seat on the middeck for Anderson to use during entry and landing. Zamka is scheduled to stow the Ku-band communications antenna at 3:03 p.m.

The International Space Station's crew is enjoying a day off duty before starting a heavy schedule of spacewalks and robotics activities which kick off with a spacewalk by Commander Peggy Whitson and Flight Engineer Yuri Malenchenko Friday morning. NASA-TV will host an Expedition 16 Mission Status Briefing at 11 a.m. today featuring the lead flight director, increment manager and lead spacewalk officer to preview the activities. The goal of the work is the relocation of the Harmony module so the station will be ready to receive the European laboratory module on the next shuttle flight, targeted to launch in early December.

The next STS-120 status report will be issued Tuesday afternoon or earlier if events warrant.
