Citing Problems With Space Shuttle Fuel Valve, NASA Postpones Launch

NASA has postponed the start of STS-128, Discovery's latest mission to the International Space Station, because of a bad fuel valve:

A problem with a fill-and-drain valve inside space shuttle Discovery's aft compartment has scrubbed the Wednesday morning launch attempt for STS-128. The launch team is evaluating the issue and has not set a new launch date and time at this point.

This is the second mission delay. Discovery was scheduled to blast off from Cape Canaveral on Aug. 4, but adverse weather conditions made a launch too risky.

According to NASA, "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 STS-128 mission crew will deliver refrigerator-sized racks full of equipment, including the COLBERT treadmill, an exercise device named after comedian Stephen Colbert.
