NASA engineers are still working to figure out exactly what caused a brief, one-time irregular power drop to one of the main engine controllers on the shuttle Discovery. But even if they fix the glitch the thrice-delayed mission faces an 80 percent chance of being delayed by weather tomorrow, Kathy Winters – NASA’s appropriately named shuttle weather officer – says. If Discovery doesn’t fly by Sunday it will have to wait until December 1 to try again.
Five amazing, clean technologies that will set us free, in this month's energy-focused issue. Also: how to build a better bomb detector, the robotic toys that are raising your children, a human catapult, the world's smallest arcade, and much more.

I know that there are alot of factors that have to be considered when planning a launch, like the weather conditions here and at the other landing sites in other countries, but there has to be another reason for NASA delaying the final launch. I can't wait to see how robonaut does in this mission.
