Space shuttle Discovery reached Launch Pad 39A at NASA's Kennedy Space Center following a slow drive on the top of the crawler-transporter from the Vehicle Assembly Building. The 3.4-mile rollout began at 2:07 a.m. and ended with the launch platform secured in place at about 1:50 p.m. The move took longer than expected because of weather conditions, including lightning.

The crawler also had to pause occasionally so mud could be removed from its treads and bearings. Technicians will quickly ready the shuttle to host the crew's countdown dress rehearsal known as the Terminal Countdown Demonstration Test, or TCDT. Discovery's seven astronauts plan to fly to Kennedy on Wednesday for the training activity which concludes later in the week with a complete practice countdown, minus liftoff, involving the crew and the launch team.

Discovery Readies for Station Resupply Flight

Space shuttle Discovery will carry the Leonardo supply module to the International Space Station during STS-128, along with a new crew member for the station, Nicole Stott.

Commanded by veteran astronaut Rick "C.J." Sturckow, the mission is targeted to liftoff Aug. 25 to deliver refrigerator-sized racks full of equipment, including the COLBERT treadmill, an exercise device named after comedian Stephen Colbert.

Stott will take the place of Tim Kopra, who moved into the station during STS-127. Pilot Kevin Ford and Mission Specialists Patrick Forrester, Jose Hernandez, John "Danny" Olivas and Sweden's Christer Fuglesang round out the crew.
