KENNEDY SPACE CENTER (AP) -- NASA experts are still scratching their heads about a glitch that has caused back-to-back launch delays.
The space agency says it will fill the shuttle Atlantis' fuel tank next week in hopes figuring out a fuel gauge problem. The trouble could be anywhere in the 100 feet of wiring between the four gauges at the bottom of the fuel tank and the shuttle itself.
At the same time, engineers will conduct other tests, mostly in laboratories, to try determine what is causing the gauges in Atlantis' tank to malfunction every time they're exposed to the super-cold liquid hydrogen that fuels the shuttle.
