All seven astronauts gave a thumbs-up as they boarded the van for the ride to the launch pad late Monday. "All right, here we go!" said commander Dominic Gorie. "Wooo!" shouted his co-pilot, Gregory Johnson.
Earlier in the evening, NASA filled Endeavour's external fuel tank; everything went exactly as planned.
Good weather was forecast for the 2:28 a.m. (0628 GMT) liftoff. It will be the first shuttle launch in darkness since 2006; only a quarter of all shuttle flights have begun at nighttime. It also will be NASA's longest space station mission: 16 days.
