Inside the cavernous Vehicle Assembly Building, workers carry out the meticulous process of lifting the orbiter Discovery from a horizontal to a vertical position. Once upright, Discovery will be transferred into a high bay for mating with the external tank/solid rocket booster assembly already mounted on the mobile launcher platform. Completing the assembly takes about five working days. Discovery's next destination: Launch Pad 39B, and final preparations for liftoff on Mission STS-70 in early June.
