NASA countdown on track for Sunday shuttle launch
Marcia DunnNASA is counting down toward Sunday's launch of space shuttle Endeavour.
The countdown clocks began ticking early Thursday.
Endeavour and a crew of six are all set to deliver a new room to the International Space Station. They're also taking up a dome with seven windows that will serve as an unprecedented lookout.
Forecasters put the odds of good weather at 70 percent. Launch time is 4:39 a.m.
The astronauts will be working the graveyard shift during the 13-day mission. Everything — all three spacewalks, and the docking and undocking of the shuttle — will take place late at night or in the wee hours.
This will be the last major construction mission at the space station, which is almost complete.
