A fuel sensor that has given NASA
headaches in the past acted up Friday morning as space shuttle Atlantis' crew prepared for liftoff.
The agency continued with launch
preparations as engineers tried to figure out if the shuttle could fly with the glitch. Atlantis' six astronauts, dressed in orange flight suits, arrived at the launch pad
and strapped into the shuttle
for the scheduled 11:40 a.m. EDT (1540 GMT) launch.
The sensor glitch was another problem the agency did not need as it rushes to get the shuttle and its crucial addition to the international space station
into orbit following several delays.
NASA managers have two options: scrub for the day and try Saturday or fly with only three of the four hydrogen fuel sensors working properly. Although no decision had been made, the space agency was leaning toward postponing for a day, said NASA press secretary Dean Acosta.
