“It is really an elegant bringing together of our exciting human spaceflight plan, scientific interest, being able to protect our planet, and utilizing the technology we had invested in and were already investing in,” said Lori Garver, NASA deputy administrator. But the mission is viewed skeptically by many in the space community. At a July gathering of engineers and scientists at the National Academy of Sciences, veteran engineer Gentry Lee expressed doubt that the complicated elements of the mission could come together by 2021, and said the many uncertainties would boost the costs. “I’m trying very, very hard to look at the positive side of this, or what I would call the possible positive side,” he said. “It’s basically wishful thinking in a lot of ways – that there’s a suitable target, that you can find it in time, that you can actually catch it if you go there and bring it back,” said Al Harris, a retired NASA planetary scientist who specializes in asteroids. “Of course there’s always luck. But how much money do you want to spend on a chance discovery that might have a very low probability?” said Mark Sykes, a planetary scientist who chairs a NASA advisory group on asteroids.”
