Space shuttle Atlantis' STS-122 mission to ISS new target date January 02, 2008

Well the shuttle was scheduled to lift off at 4:31 p.m. EST on Thursday
to begin mission STS-122.
That didn't happen because of a failure of two Engine Cutoff (ECO) low
level sensors for the liquid Hydrogen in the external tank during filling.

Rescheduled for today, December 9, 2007, which is now a no go as well as
one of the ECO sensors gave a false reading.
Launch now put off until no earlier than January 2, 2008.

The liftoff date depends on the resolution of a problem in a fuel sensor
system.
See NASA press release below.

Closer to home, what do you do when your engine warning sensor light
comes on?
Something not up to specs, maybe a problem, can you get home before you
start making smog or it stalls?
What can you do until it is more convenient to take it to the garage?
Decisions, what is safe?

When you go to the Moon, what warning sensors will you need?
Do you have enough water?
Do you have enough Oxygen for breathing?
Do you have enough atmospheric pressure to do your breathing?
Is the temperature within limits?
How much radiation exposure?

Then what do you do if any are outside of norms?
Do you adjust the norms?
Decisions, what is safe, what can you get by with?

Thanks for looking up with me.

NASA TARGETS SPACE SHUTTLE ATLANTIS LAUNCH ON JAN. 2

CAPE CANAVERAL, Fla. - Space shuttle Atlantis' STS-122 mission to the
International Space Station now is targeted to launch no earlier than
Jan. 2 from NASA's Kennedy Space Center. The liftoff date depends on
the resolution of a problem in a fuel sensor system.

Early Sunday, one of the four engine cutoff, or ECO, sensors inside
the liquid hydrogen section of Atlantis' external fuel tank gave a
false reading while the tank was being filled. NASA's current Launch
Commit Criteria require that all four sensors function properly.

The sensor system is one of several that protect the shuttle's main
engines by triggering their shut down if fuel runs unexpectedly low.
Atlantis' scheduled launch on Thursday, Dec. 6, was delayed after two
liquid hydrogen ECO sensors gave false readings.

The main objective of Atlantis' 11-day mission is to install and
activate the European Space Agency's Columbus laboratory, which will
provide scientists around the world the ability to conduct a variety
of life, physical and materials science experiments.
