The progress of the fourth expedition to the International Space Station will be discussed during a Mission Status Briefing beginning at 2 p.m. EST Thursday, Feb. 14, from NASA's Johnson Space Center in Houston.
The briefing will be broadcast on NASA Television with question-and-answer capability for reporters from other NASA centers.
Mission managers will offer an update on activities aboard the space station, including a spacewalk Feb. 20 by Flight Engineers Carl Walz and Dan Bursch out of the Quest Airlock. This will be the first use of the station's airlock since July 2001 and sets the stage for four spacewalks out of Quest to attach the first of several large truss segments to the complex during a space shuttle mission scheduled for early April.
Walz, Bursch and Commander Yury Onufrienko are in the third month of a planned five-month stay aboard the orbiting research laboratory.
Participants for Thursday's briefing include:
NASA Television is available on GE-2, Transponder 9C at 85 degrees West longitude, vertical polarization, with a frequency of 3880 MHz, and audio of 6.8 MHz.
