Was this the same problem as with the old tank? was it the same sensor?
It smells like an electronic circuit problem, rather than a sensor one,
especially if it can be duplicated. Some mileage might be gained by looking
at the history of this sensor and if anything has been ...

AND WE ALL HOPE THAT DISCOVERYS LAUNCH WILL BE A BIG FLOPER AND THE
PARTS BE ON EBAY IN 3 DAYS.

From a CNN article
(http://www.cnn.com/2005/TECH/space/07/19/space.shuttle/index.html):
   To help find the malfunction, NASA has brought out of retirement
   an engineer who designed part of the sensor system back in the 1970s,

When the shuttle launches it will go up the East coast of America ?
New York is 900 miles North so the Shuttle will be passing New York not long
after launch.
Now for the daft question, if the weather is clear a very sunny day will it

Part of the limitation in the current "daylight" launch window is that the
Crew must be able to take pretty pictures of the ET after it has been
separated from the shuttle to inspect for any damage.
Right now, they seem to dump the ET fairly soon after launch so it falls in

I'd like to ask some questions to anyone who might know (not just think
they know) about the ET fuel sensors. My guess (and it's just a guess)
is that they might be cryogenic temperature sensors. I suppose they
could be low T pressure sensors, but I don't know anything about such ...

CNN is trying to explain the issue with the fuel sensor in layman's terms.
It's reminding me of the Ed Asner skit on Saturday Night Live, "you can't
put too much water in a nuclear reactor." The text of the explanation goes
like this:

Read this on another newgroup.
"I remember reading that on the approach, if
they heaved a housebrick out of the window at 40,000 ft, the shuttle
would reach the ground first."

Here's a non-scientific poll for the sci.space.shuttle group.  Please
answer according to what you think _will_ happen, not according to what
you think _should_ happen.
Before launching STS-114 the ECO sensor problem must be dealt with.  At

Press conference just finished.
"Cryogenic test" is the next step -- filling the tank with liquid hydrogen
and
oxygen to see what anomalies are detected, or can be forced using test

Does anyone have the freqs for Mission Control so I can monitor it HF.
I am looking for the guy who does count down and such. Thanks in
advance.

Maybe the needle is just stuck...

Interestingly, the Japanese on the H-II also had launch delays searching for
the cause of a malfunction of a depletion sensor:
