The Mission Management Team made the decision based on extensive analysis, said a statement by NASA.
Earlier Thursday, the STS-114 and Expedition 11 crews paid tribute to astronauts and cosmonauts who have given their lives for space exploration. Wearing red shirts with the STS-107 patch, each crewmember provided words of tribute and remembrance in their native languages -- English, Russian and Japanese. Following the tribute, the crew had an off-duty period.
TS-114 is the first space shuttle mission to fly since the loss of Columbia and the STS-107 crew -- Rick Husband, Willie McCool, Michael Anderson, Dave Brown, Kalpana Chawla, Laurel Clark and Ilan Ramon.
