NASA Readies Discovery Shuttle For Final Flight 153
gabbo529 writes "After 38 trips, 352 days in orbit and more than 5,600 trips around the Earth, the space shuttle Discovery is preparing for its final launch. Since its creation, it has flown to orbit more than any other craft. It has set a number of precedents including first craft to feature a female shuttle pilot and female shuttle commander (Eileen Collins), the first African American spacewalker (Bernard Harris) and the first sitting member of congress to fly in space (Jake Garn). In its final foray into space, the Discovery will set another precedent when it flies the first humanoid robot to fly in space, Robonaut2."

First female commander earns praise for "safe, if overly cautious" flying

Even before NASA's first female mission commander touched down on the tarmac at Kennedy Space Center late Tuesday evening, investigators were speculating on the possible cause of the fuel leak observed at the launch of shuttle Columbia at the start of its historic 5 day mission.
"At first we thought maybe she left the gas cap off," reported Chief Inspector Gerald Schmitt during a post-mission press conference yesterday. Schmitt was referring to mission commander U.S. Air Force Col. Eileen Collins, who led STS-93 to a complete success despite the glitches that plagued the start of the mission.
However, the inspectors ruled out that scenario after an exhaustive examination of the video launch records. They are now considering alternative theories, as well examining the shuttle engines for possible damage, such as a burned-out clutch. "We'll get in there and take a look," explained Schmitt, "but the real test will come on the next flight for Columbia, when the next mission commander can let us know if the shuttle still handles the way it did before."
Schmitt went on to explain that the launch is usually performed in an "Automatic" mode, but the shutdown of 2 flight computers just seconds into Friday's launch required Col. Collins to switch to "Manual" mode, which she may have had less experience with in the past.
Shuttle failed to reach "nominal" altitude
By the time main engine cutoff, or MECO, took place at the end of Columbia's vault into space, the shuttle was about 7 miles beneath its intended orbit. At the time, NASA had not yet confirmed the fuel leak, so ground control was at a loss to explain this result.
Launch controller Peter "Pete" Castle recalls, "For a few minutes I was beside myself. Did [Collins] fail to advance the engine throttles to 104 percent as called for in the launch sequence? Everyone knows you can drive those engines a little bit over the limit. There aren't any cops in space. Why are we here staying under the limit? We'll never get where we need to go like that."
Fortunately, Columbia had sufficient fuel onboard to boost itself to its full intended orbit, and the mission objectives and the crew were never in danger.
"She really took us by surprise"
Mission controllers at the Johnson Space Flight Center in Houston, Texas, were very complimentary of Col. Collins. Third shift controller Michael Childs recalls one incident in particular:
"During orbit 15 of the mission, Col. Collins called down for directions on the next scheduled maneuver. At this point in the schedule we had not expected any communications from Columbia. Past shuttle commanders always ran through this sequence without asking for directions, even if they had lost track of where they were. It is a little known fact that on STS-96 [when shuttle Discovery docked with the International Space Station (ISS)], Mission Commander Kent Rominger reached the station three orbits late, basically because he insisted on 'just flying around in circles until we found it', to quote Mission Specialist Patty Jernigan."
Most call the landing 'flawless'
The touchdown of shuttle Columbia in the final minutes of Tuesday evening was called "flawless" by ground controllers at the KSC. However, U.S. Air Force Col. Jack "Cracker Jack" Jackson, the last mission commander for a Columbia mission, was more critical.
"That's not where I left it," Jackson said of Columbia, noting that Columbia rolled to a stop on the runway over 500 yards earlier than it did when he landed the same vehicle back in February, 1998. "When you take that baby out for a spin, I expect you to put it back where it belongs when you're done." After a moment, Jackson added one final thought, "God, I don't want to think what happened to those brakes."
