Countdown to lift-off!

The countdown has begun for tomorrow's launch of space shuttle Endeavour on a mission to deliver a porch to the International Space Station. It's nice to think that even NASA is interested in home improvement like the rest of us.
The new platform will complete Japan's elaborate three-part Kibo laboratory complex, the station's newest and largest module.
"This has been a long journey for us and our Japanese colleagues," said Scott Higginbotham, who oversees station payloads at NASA's Florida launch site.
For about six years, Japanese space agency technicians have worked side-by-side with NASA personnel in Florida to prepare Kibo. The first two sections of the lab were launched last year and this will complete the structure.
The astronauts plan to conduct five spacewalks to hook up Kibo's new porch, replace batteries on one of the station's solar panel wings and to position spare parts on platforms outside the station. The porch is a platform for experiments that require direct exposure to space - it's not somewhere to enjoy a cool drink in an easy chair and watch the sun go down.
The shuttle and its seven-member crew is scheduled to lift off at 7:17 a.m. EDT/1117 GMT tomorrow for a 16-day mission. Good luck to them...
