Shuttle Launch Delayed

via LiveScience, a faulty fuel sensor has delayed the launch of shuttle Atlantis from its scheduled launch today.

"Faulty readings in two of four hydrogen fuel gauge sensors prevented Atlantis from launching from NASA's Kennedy Space Center here at 4:31 p.m. EST (2131 GMT). NASA flight rules call for three operational sensors in order to launch."

"Per our launch criteria we scrubbed the launch attempt," said NASA spokesperson Allard Beutel, adding that mission managers called off the launch at 9:56 a.m. EST (1456 GMT). "We'll try again tomorrow."

The STS-122 mission is expected to launch tomorrow to deliver the European Columbus laboratory moduleto the International Space Station.
