Room for Debate: Where, If Anywhere, Is NASA Headed? Scientific American

On complex issues, as is often said, it is possible for intelligent people to disagree. That was certainly the case March 15 at the American Museum of Natural History in New York City, when five leaders of the space exploration intelligentsia met to discuss NASA’s plans for human spaceflight.
The topic of the event, the 10th annual Isaac Asimov Memorial Debate, could hardly have been more timely, given the February budget request from President Obama that sought to drastically change NASA’s direction for human spaceflight and the way the agency does that business. If the budget survives Congress, NASA could start hiring private corporations to launch U.S. astronauts into orbit rather than use its own hardware; Obama’s plan would also scrap the existing Constellation Program, including the Ares rockets being developed to lift humans beyond low Earth orbit for the first time since the 1970s.
