NASA Works Out Kinks On Shuttle and Space Station

NASA has been recreating gauge problems that grounded shuttle Atlantis earlier this month. 
Engineers started filling the spaceship's external tank with liquid hydrogen fuel at daybreak in a test at the launch pad to pinpoint the trouble.

One of the four gauges promptly failed, and two others were not working consistently. Meanwhile, a pair of space station astronauts are out on a spacewalk to inspect two defective mechanisms that are hobbling power generation at the International Space Station.

Astronauts on the space shuttle Atlantis were supposed to do the inspection, but that mission is delayed until at least January.
