So how are they going to launch tomorrow if they will have the same sensor
failure. I thought that they had to return the shuttle to the VAB in order
to change out the sensor. Do they have enough time to do anything about
this problem before launch time tomorrow?

George

So, how will just doing it again tomorrow help them out?

Surely, whatever the outcome, the sensor needs either to be changed or
masked out of the equation, and I'm not sure that is allowed. Its not
reliable, end of story.

Anyone know where it is located?

Maybe empting and refilling the tank will fix it. They sure have been
having problems with the ECO sensors.

It's in the bottom of the Hydrogen tank.

Beats me. I guess they're hoping it was some sort of contamination
that will wash off or not settle in the same place the next time it's
fueled up.

I thought there was an increased risk of foam separation every time the tank
is filled and drained due to expansion/contraction? Is there anything
factored in for that risk?

Surely the risk of launching with 1 of 4 sensors faulty has to be weighed
against that?

As I recall, the last time they had this problem, they had to swap out
tanks, which caused a two month delay.
