Spacewalking astronauts installed a new front door for visitors at the International Space Station on Friday, the crucial first step in welcoming commercial crew capsules as soon as next year. The last NASA spacewalk in January was cut short because of a small water leak in one helmet. "Thanks for your help in getting the front door on the space station," Mission Control radioed. The space station is currently home to two Americans, one Japanese and three Russians. These test flights — intended to go all the way to the space station and dock — will last about two weeks.
