The tanks contain hydrogen and oxygen. A combination of the two power it.
If it runs out of either, it can blow, or overspool the engine - either
would be fatal. So it needs accurate fuel sensors - unless you want to
fly it. Crew safety is paramount - and right now it's compromised.

Discovery can't take off because of a bad fuel sensor ? Are they kidding us
? The crew is already strapped in, number one for departure, cocked and
loaded. We just put gas in the thing. I saw the line guys top the tanks
earlier in the day. Stick the tank, placard the gas gauge inop and let's go
haul the mail ! Now it takes three or four days to replace it ? They need
to find a new A&P, preferably non-union. We are never going to get
commercial space travel at this rate. I'm sure the FAA is to blame too ...
somehow.
