CAPE CANAVERAL, Fla. — Seven NASA astronauts and the space shuttle Endeavour are poised to launch Friday evening on what they've called an extreme home-improvement job at the International Space Station. Endeavour is set to blast off at 7:55 p.m. EST (0055 Nov. 15 GMT) from a seaside launch pad at NASA's Kennedy Space Center hauling a cargo pod packed with new life-support gear, including a $250 million recycling system that turns astronaut urine into drinkable water. "This mission is all about home improvement," said Endeavour commander Chris Ferguson. "Home improvement both inside and outside the space station."
