No Endeavour launch today—or probably this weekend either. NASA postponed the high-profile launch to investigate trouble with heaters in the shuttle's power system, reports MSNBC. No word yet on what that means for the day's most awaited spectator, Gabby Giffords. Husband Mark Kelly and crew were less than four hours from liftoff when the news broke. The next attempt will likely be Monday at the earliest, reports AP.

"They are trying to assess what all is going to be required and how much time we're going to need," said a NASA official. "We still don't know what's wrong or why these multiple heater failures occurred." Despite the postponement, President Obama planned to travel to Cape Canaveral anyway for a tour and a possible meeting with Giffords. (More NASA stories.)
