Space Shuttle Discovery
After departing the Vehicle Assembly Building (VAB), the Space Shuttle Discovery moves slowly -- about one mile per hour -- along the KSC Crawlerway toward Launch Pad 39A in preparation for the STS-82 mission. The Shuttle is on a mobile launch platform, and the entire assemblage is being carried by a large tracked vehicle called the Crawler Transporter. A seven-member crew of astronauts performed the second servicing of the orbiting Hubble Space Telescope (HST) during the scheduled ten-day STS-82 flight in February 1997.
