Space Shuttle Discovery's Last Rollover to the VAB | Universe Today

DogBoy
Rollover, the name itself is not all that awe-inspiring, the sight however; will take one’s breath away. The space shuttle Discovery emerged from its technological cocoon located in Orbiter Processing Facility-3 (OPF-3) at 7 a.m. EDT on Sept. 9, 2010 and was moved into the expansive Vehicle Assembly Building (VAB) a few hours later. The short, but slow trek allowed workers, many of whom have spent their entire careers servicing the orbiter, to pose with Discovery as she made this voyage.

Discovery’s trip to the VAB was delayed a day from Wednesday to Thursday, due to a broken water main. Workers found the break in a pipe located near the VAB and repaired it enough to allow second-shift workers to go to work later in the day.

“The pipe that broke was 50 years old,” said Allard Beutel, a NASA Public Affairs Officer. “The Kennedy team managed to have a work-around in place in under a day.”

Rollover is an important milestone on the road to flight. In this case, the occasion was all the more historic as it marked Discovery’s final trip to the VAB for this reason. The orbiter is flanked by workers that have worked to see that the shuttle is prepared for flight. They act as guides ensuring that there is no debris along the short drive that the transport vehicle takes from OPF-3 to the VAB. There were several stops along the way to allow photographs to be taken; marking the last time that Discovery is scheduled to move to the VAB in preparation for flight.

Once inside the VAB Discovery was connected to a crane that hoisted the 171,000 lb. space glider into the air. From there it is mated to a set of Solid Rocket Boosters (SRB) and External Tank (ET) waiting for the orbiter’s arrival. Seeing this massive spacecraft hanging in mid-air alters one’s perceptions about the U.S. space program. It places a powerful spotlight onto the efforts required to put astronauts into orbit.
