Find more info on 2012 Event at bit.ly . . . On November 5th, 2010 NASA scrubbed the launch of Space Shuttle Discovery due to a Hydrogen leak. At first it looked like this was just another GUCP issue which vents the Hydrogen boiloff away from the vehicle. However as engineers inspected the tank a bit further large cracks in the insulation foam were detected which later led to the finding of cracks in metal stringers. As more cracks were found, NASA decided to delay the launch until 2011 to allow additional time for testing. At noon UTC this last Friday NASA began that testing with a full on fueling of Space Shuttle Discovery’s orange external tank. Half a million pounds of super cooled liquid hydrogen and oxygen were loaded in to the tank while engineers collected data from sensors. At 19:25 UTC the tanking test completed after NASA had fully pressurized and simulated pre-launch conditions. The initial verdict is that no issues were found. The GUCP was not leaking and from what they could tell no additional stress on the external tank was exhibited. NASA needs some time to evaluate the data further, but thus far it is looking good for an early February launch. While the tanking tests are completed, NASA is not done analyzing the vehicle yet. After filling the external tank with all that fuel they then emptied in in preparations to roll the entire shuttle stack back to the vehicle assembly building this Tuesday. Once there engineers will take X-Rays of the external tank to …
