The six crew members of space shuttle Endeavour are donning their orange flight suits as they get ready to head out of the crew quarters at Kennedy’s Operations and Checkout Building to Launch Pad 39A where space shuttle Endeavour awaits their arrival.
Forecasters have changed the chances of acceptable conditions to 60 percent favorable for launch after determining there is a risk of low clouds blowing in near launch time. Weather will continue to be monitored with reconnaissance flights and weather balloons.
There are no technical issues being reported and the countdown continues toward a 4:39 a.m. EST liftoff.
