摘要

Nasa's Space Shuttle Discovery was rolled back from its launch pad to the Vehicle Assembly Building at Kennedy Space Center in Florida May 26 so engineers can swap out the orbiter's external fuel tank as a safety precaution. Discovery's seven-astronaut crew had planned to launch spaceward May 22 for a 12-day flight that, would not only restore NASA's independent ability to loft humans into orbit, but also test new safety measures and resupply the international space station (ISS). However, concerns over the potential danger of ice debris from Discovery's external tank led mission managers to call for a swap, delaying the launch to no earlier than July 13.
