America's first Space Shuttle, Columbia, will return to orbit fresh from two years of work that have left it safer and more capable than ever before.
Columbia is set to launch Feb. 28 at 6:48 a.m. EST on mission STS-109, pending review of data on the Space Shuttle's hydraulic pump attach bolts. The mission is dedicated to maintaining and enhancing the Hubble Space Telescope, the fourth such flight since the telescope's launch in 1990.
"Returning Columbia to orbit to improve the Hubble Space Telescope is a fitting start to what will be a busy and vital year in space." said Space Shuttle Program Manager Ron Dittemore. "We have more spacewalks planned in the next 12 months than we have ever done in a single year. We are going to fly diverse missions, dedicated to satellite maintenance, research and Space Station assembly, showcasing capabilities unique in the world. The shuttle team has done a great job in preparing for this mission."
A maintenance and upgrade period completed last year installed a new "glass cockpit" in Columbia, increased its cargo capacity, strengthened its crew cabin and enhanced the protection of its cooling system from orbital debris.
Columbia's new cockpit replaced mechanical instruments with 11 full-color, flat-panel displays. The new cockpit is lighter, uses less electricity and sets the stage for the next generation of improvements -- a "smart cockpit" under development that will make the cabin even more user-friendly.
Columbia is the second of NASA's four Space Shuttles to be fitted with the new "glass cockpit." Technicians also performed comprehensive inspections of the Space Shuttle's more than 200 miles of electrical wiring, installing protection to prevent future damage in high-traffic areas. Intensive structural inspection of Columbia also was performed as well as 133 modifications and upgrades.
The orbiter will fly under the command of Scott Altman (Cmdr., USN). Duane Carey (Lt. Col., USAF) will serve as pilot. Mission specialists will be John Grunsfeld, Nancy Currie (Lt. Col., USA), Richard Linnehan, James Newman and Michael Massimino. Grunsfeld, Linnehan, Newman and Massimino will work in alternating teams of two to perform the five planned spacewalks.
Columbia's flight is scheduled to end with landing back at NASA's Kennedy Space Center in Florida March 11. STS-109 marks the 27th mission for Columbia and the 108th in Shuttle program history.
