it appears theres a question of wether to run a test filling the tank,
to test the low fuel sensors, that were just replaced.

Although a test can show wether the sensor trouble has been fixed the
foam is believed to be damaged by filling the tank repeatedly. the
expansion and contraction can cause cracking leading to more foam loss
that will likely end the program forever

what a interesting catch 22.

another failure of the sensors will lead to long futher delays

more foam loss probably end the program forever

either way nasa loses....
