NASA has set an early February launch date for space shuttle Endeavour. Senior managers met Wednesday and decided unanimously to proceed toward a Feb. 7 launch date for Endeavour. It will be a pre-dawn liftoff at 4:39 a.m.

Endeavour will carry up a new room and observation deck for the International Space Station, the last of the major U.S. components. The six-person crew will hook up the chamber, named Tranquility, during a series of spacewalks.

Some of the ammonia coolant lines for chamber failed testing earlier this month. So engineers scrambled to fashion new hoses out of old hardware.

Only five shuttle flights remain.
