"Contrary to this administration's rhetoric, the President's proposed Asteroid Redirect Mission (ARM) has many skeptics within the scientific community. And the experts who advise NASA recently stepped up their criticism. The NASA Advisory Council warns that NASA 'runs the risk of squandering precious national resources' if they move forward with ARM. One expert, Mr. Tom Young, went so far as to say that the ARM proposal 'dumbed down NASA.' For months, the Obama administration has downplayed such criticism. I appreciate the good work of NASA's technical advisors and encourage the Obama administration to take their recommendations seriously."
SBAG Asteroid Redirect Mission Special Action Team, July 2014 presentation
"This report summarizes discussions and findings of the SBAG ARM SAT. The report will be presented at the SBAG meeting on July 30, 2014, and made available to the SBAG community for comment. The report will be finalized in August, 2014, following the opportunity period for comments. The SBAG ARM SAT echoes the statement in the CAPTEM ARM report: of necessity, this is a preliminary report. If such a mission goes forward, we recommend that the prioritization of the science, planetary defense, and resource utilization requirements be refined through a more comprehensive process."

"Another criticism is that NASA does a poor job of explaining why it is pursuing ARM. Williams used a chart with several bullets, one of which pointed to ARM's role in demonstrating techniques that could be used to defend Earth from potentially hazardous asteroids -- planetary defense. During questioning about those bullets, Bolden quickly chimed in to say that planetary defense is NOT a goal of ARM. It is a goal of the Asteroid Grand Challenge, which NASA is funding at $7 million in FY2014, he said, but not of ARM. He acknowledged that because NASA is doing both ARM and the Grand Challenge, there is a lot of confusion. "We need to get that confusion out of it. We are not saving the planet," he exclaimed. However, many other NASA officials, including Williams, include planetary defense in the list of rationales for ARM. Scott Hubbard insisted that NASA needs to have a single bullet explaining why ARM is needed, not a list of them, in any case."
