【 摘 要 】

There are three primary reasons why it is important for NASA to develop better ways to locate and characterize Near Earth Objects (NEOs). First, NEOs are an impact hazard to the Earth and congress has mandated that NASA find 90 percent of all the Potentially Hazardous Objects (PHOs) over 140 meters by the end of 2020. NASA will fail to meet this mandate due to funding limitations and the cost and technical performance of current asteroid survey approaches. The Sutter Survey will solve this problem. Second, measuring NEO population distributions will unlock the answers to critical questions dealing with the formation and evolution of the solar system. Finally, NEOs are important targets for human exploration and they represent a virtually unlimited long term resource of valuable material for radiation shielding, propellant, and life support consumables that could make NASA'splanned deep space human exploration program affordable.
