Well, now the Space Shuttle won't be launched until sometime next week, at the earliest, according to CNN:

KENNEDY SPACE CENTER, Florida (CNN) -- The first space shuttle launch since the 2003 Columbia disaster will not take place until late next week at the earliest, NASA spokesman Mike Rein said Friday.

NASA previously had said the shuttle Discovery could lift off as soon as Sunday, although it was unlikely.

The launch originally was scheduled for Wednesday, but it was scrubbed 2 1/2 hours before liftoff because of a faulty fuel sensor.

The space agency has until July 31 to attempt a launch or must wait until September.

"We are still looking at launching during this window," NASA spokesman Allard Beutel said.

Beutel said the delay will allow NASA "more time to work on our troubleshooting plan."

If one considers the difficulty of discovering the cause of an electrical problem in one's car, one can only imagine how hard this seemingly minor issue is likely to be.
