In its history, the Earth has been repeatedly struck by asteroids, large chunks of rock from space that can cause considerable damage in a collision. Can we—or should we—try to protect Earth from potentially hazardous impacts? Sounds like stuff just for rocket scientists. But how would you like to be part of this discussion? Now you can! NASA is collaborating with ECAST—Expert and Citizen Assessment of Science and Technology—to give citizens a say in decisions about the future of space exploration. Join the dialogue below about detecting asteroids and mitigating their potential impact. The five recommendations below emerged from ECAST public forums held in Phoenix and Boston last November. Please take a few moments to review the background materials and the recommendations, and tell us what you think! Your input is important as we analyze the outcomes of the forums and make our final report to NASA.
