Discovery scheduled to return to space

The NY Times reports on the latest news from Cape Canaveral:

CAPE CANAVERAL, Fla., July 26 - The shuttle Discovery awaits its return to flight this morning with no sign of the sensor troubles that have bedeviled NASA's last attempt to launch.

At 6:43, the three-hour launch countdown began. If the launching takes place as planned at 10:39 this morning, it will be the first shuttle flight since the loss of Columbia and its crew of seven astronauts over Texas on Feb. 1, 2003. The probability that the launch might have to be scrubbed because of local weather conditions has dropped to just 20 percent.

We'll post more information on the shuttle's progress as it develops.
