Where we're headed with STS-122
Next Tuesday, December 18th, Atlantis's External Tank (ET) undergo a cryogenics test. The ET will be filled with supercold hydrogen to test the low-level sensors. They're pretty certain that sensor(s) will fail during the test, however, some test instrumentation will be hooked up near a control unit in the shuttle's aft engine compartment to hook up test instrumentation that should help locate any bad wiring or connectors in all the cabling between the control unit box and the sensors at the base of the ET. Launch is still set to no earlier than Janaury 2nd. But we should have a better direction of where we're headed with a fix and a launch date once we determine the root cause from the test.
