NASA decided to delay the launch and allow the teams additional time.New potential launch dates for Discoveryâs STS-133 mission and shuttle Endeavourâs STS-134 have yet to be determined, 06 Jan 2011. The U.S. space shuttle Discovery's upcoming mission to the International Space Station has been delayed again, as NASA continues work to repair the shuttle's external fuel tank. The U.S. space agency says it is now considering potential launch dates in late February, not early in the month as previously planned. Cracks in some of the metal supports of Discovery's fuel tank were discovered when a hydrogen leak led NASA to cancel a planned launch attempt in early November. NASA officials now say the shuttle could launch as early as February 24. At this point, the Discovery supply mission is the next-to-last in the agency's 30-year shuttle program. But another flight could be added mid-year, before the fleet is set to retire this year. .
