The official countdown clock is ticking for the STS-130 mission of space shuttle Endeavour to the International Space Station. This is the last planned night launch for the shuttle program, with a scheduled liftoff time of 9:39:47 GMT (4:39:47 a.m. EST) on Sunday, February 7. "Everything thus far is going exceeding well… we're right on schedule where we're supposed to be and we'll continue to work through the day on our preparations," said NASA Test Director Jeff Spaulding during this morning's L-3 Countdown Status Briefing at KSC. The weather forecast might be the only issue, as forecasters are predicting a 70% chance of favorable weather, with high winds being the only concern for Sunday morning.
