Looks like we'll be counting down a few more days until the final mission of the space shuttle Endeavour. NASA has told CNN that there still isn't an exact timetable for the made-for-cable event, only that it will be after May 10th. The launch had already been postponed twice due to technical glitches prior to its heavily-hyped April 29th schedule date. When the shuttle's problems with one of its auxiliary power units were first reported, NASA set the rescheduled launch time to this last Monday.
