Technical Problem Delays Shuttle Launch

KENNEDY SPACE CENTER (AP) -- A recurrent technical problem with some space shuttle fuel gauges has forced the postponement of today's scheduled launch.

NASA says it'll try again to send Atlantis on its way to the international space station tomorrow.

The shuttle's big external fuel tank has four sensors that tell computers whether the tank is filled with liquid hydrogen. Two of them indicate the tank is dry, when in fact it's full. The rules say three of those four gauges called ECO (EE-'koh) sensors must be working properly before launch.

If NASA engineers can troubleshoot the problem in time, tomorrow's liftoff would be scheduled for 4:09 p.m. Eastern Time.
