"If we do happen to delay 24 hours we start to get a little more concerned," Winters said. "There's a 30 percent chance of KSC weather prohibiting launch."
If the shuttle's liftoff is delayed by 48 hours, the chances of bad weather disrupting the launch rise to 60 percent.
Plans for launch appear to be progressing smoothly, with no last-minute issues hindering preparations. Shuttle workers have packed away a last-minute addition, a spare toilet pump for the space station's bathroom, so astronauts aboard the outpost can repair the space toilet in orbit. The station's toilet went on the fritz last week and astronauts need the new pump to restore it to full service.
Looks good so far :)
Biggest problem was finding a rotorooter guy space flight qualified and willing to work for crappy wages (pun intended).

I have to believe that the most welcome reason for getting back to Terra Firma after an extended trip to the station would be the simple pleasure of sitting down and letting gravity do its thing. :^)
