"John Logsdon, professor emeritus of George Washington University's Space Policy Institute, said the report has a familiar ring to it. "They go through all this negative analysis and still conclude we ought to go to Mars. No one ever says, 'Let's lower our ambitions.' It's always, 'Increase the budget,' not 'Lower ambitions,'" he said. As for going to Mars: "It's a dream. It's been a dream forever. And will remain a dream unless something changes."
"But the report said that if the U.S. is to take its space program to the next level, it will require more funds for the step-by-step missions that will lead to the Martian surface. It will also require, the authors said, more international cooperation -- including with China. Current federal law blocks NASA from working on bilateral projects with the Chinese."
New report: NASA Mars goal is not viable, Houston Chronicle
"There is also concern because, critics say, NASA is building this rocket without a clear path to Mars. As the report notes it is difficult to sustain a rocket program, absent a concrete, widely accepted goal, over multiple presidential administrations, and Congresses. "I would say the SLS is very vulnerable," said Mark Albrecht, an aerospace executive and principal space adviser to President George H.W. Bush, this year. "The wrong way to think about spaceflight is to build a bunch of stuff and then find an objective for it to achieve."
Keith's note: NRC says NASA Is on the wrong path to Mars. That's about the only thing they took a clear position on in their report. In writing their report the committee dodged all of the big questions with the excuse that it was beyond their scope/charter. Trivial mention was made of commercial alternatives or whether the SLS-based model is the right way to get to Mars. In the briefing yesterday Mitch Daniels said that funding for all of this is "the secondary question". So there you go - yet another space policy report - one that cost $3.6 million and is being delivered more than 3 years after it was requested. The White House and NASA will ignore it. Congress will wave it around and then ignore it too. In the end we'll all be where we are now - with incomplete plans, no strategy, a big rocket with no payload, and nothing close to a budget to make any of it happen.
