HOUSTON, May 20 (UPI) -- U.S. spacewalkers at the International Space Station completed the first step to repair a slow leak in a thermal control system cooling loop, NASA said Friday.
Endeavour mission specialists Drew Feustel and Greg Chamitoff installed an ammonia jumper cable that will connect cooling loops of the ISS's port 3 and 4 segments, the U.S. space agency said on its Web site.
