JOHNSON SPACE CENTER, Texas, Aug. 4 (UPI) -- A fourth space walk to fix a thermal blanket near shuttle Discovery's left window will not be needed, the crew was told by Mission Control in Houston Thursday.
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.
