AP reports:
The problem initially was a faulty fuel sensor reading on the external
fuel tank. It seemingly passed the test this morning.
"All the sensors are performing as expected," said NASA commentator Jessica Rye.
If the equipment trouble reappeared, NASA was prepared to bend its safety rules and press ahead with the launch anyway with just three of the four sensors working. Only two sensors are needed to do the job. But ever since NASA's return to space in 1988 after the Challenger explosion, the space agency has decreed that all four have to work.
NASA Administrator Michael Griffin called such a deviation from the rules "an acceptable risk."
"Actually, it's quite a low one," Griffin told The Associated Press on Monday.
Lets hope everything goes well today....
