Two spacewalking astronauts got the power pumping in a new room in the International Space Station on Sunday. An ammonia leak, which spattered astronaut Nicholas Patrick's suit with the toxic substance, didn't stop him from making the much-needed repairs while floating in space. More>>

NASA Investigates Shuttle Sabotage

NASA does not actually suspect sabotage be-hind the glitch that has twice delayed the launch of the space shuttle Endeavour recently. But with any problem without an apparent explanation, the space agency is investigating all possibilities, including intentional tampering, officials said.

Endeavour's STS-127 mission was supposed to lift off June 13, but a leak of hydrogen gas from a pipe attached to the shuttle's fuel tank grouded the vehicle. NASA tried to launch a second time on Wednesday, but again the leak appeared, even after workers replaced the leaky seal between the pipe and shuttle. More>>
