NASA begins countdown for space shuttle 'Endeavour'

Countdown begins again for 'Endeavour'

NASA's countdown clocks began ticking again Friday for the next-to-last space shuttle launch, delayed two weeks ago by an electrical problem aboard Endeavour. Forecasters put the odds of good weather for Monday morning's launch at 70 percent: the main concerns are stiff crosswind and low clouds. NASA test director Jeff Spaulding said everything was on track this time around, and that the most likely culprit for last month's failed launch attempt was an exposed conductor on a thermostat. The thermostat was replaced last week, along with a switch box containing a blown fuse. Commander Mark Kelly and his five crewmates returned to Kennedy Space Center on Thursday. Their families will follow this weekend, including Kelly's wife, Arizona Rep. Gabrielle Giffords, who was critically wounded in the head in January at a political event in Tucson. She interrupted her rehab in Houston to travel to Cape Canaveral for the first launch attempt, and will do so again.
