STS-121 Launch Scrubbed on Saturday

Today’s launch of Space Shuttle Discovery has been postponed for 24 hours because of weather. The preferred launch time for tomorrow is 3:26 p.m. from Kennedy Space Center.

Steven Lindsey commands a crew of five American astronauts, Pilot Mark Kelly and Mission Specialists Michael Fossum, Lisa Nowak, Stephanie Wilson and Piers Sellers, and one astronaut from the European Space Agency, Thomas Reiter. This is the 18th U.S. flight to the International Space Station and the 32nd flight for Space Shuttle Discovery.

In Discovery’s payload bay, the multi-purpose logistics module Leonardo, built by the Italian Space Agency, will deliver more than two tons of supplies, equipment and tools on its fourth trip to the station.

While docked, the STS-121 crew will test new equipment and procedures to improve shuttle safety, as well as make repairs to the station. Reiter will remain with the Expedition 13 crew on the station.
