"Proposed Extension of the Space Shuttle Program
To maximize safety, minimize wasted effort, and bolster employee morale, any further debate regarding the future of the Shuttle should be undertaken immediately and completed without further delay. From a safety standpoint, the ASAP strongly endorses the NASA position on not extending Shuttle operations beyond successful execution of the December 2008 manifest, completing the ISS. Continuing to fly the Shuttle not only would increase the risk to crews, but also could jeopardize the future U.S. Exploration program by squeezing available resources (and, in the worst case, support) for the Constellation program."
