CAPE CANAVERAL, Fla. (AP) -- NASA began the countdown Sunday night for the launch of Endeavour after completing one final test to make sure the space shuttle's crew cabin was airtight.

"The team is ready. Endeavour is ready," said NASA test director Stephen Payne.

Last week, NASA replaced a leaky valve in Endeavour's cabin with one taken from the shuttle Atlantis. Engineers discovered that air had been escaping from the removed valve because of a small piece of debris on its seal, Payne said. The valve itself turned out to be fine.
