[REBROADCAST] Asteroids! In just two weeks, NASA plans to launch a first-of-its-kind mission to try to move an asteroid off its path. If it works, this could be a huge breakthrough in protecting us from runaway space rocks. So we’ve updated this episode from a few years ago, where we talked about how serious this asteroid threat is — and some of the other ways we might fight back. We speak with asteroid researcher Dr. Alan Harris, astrophysicist Dr. Sergey Zamozdra, computational physicist Dr. Cathy Plesko, and physicist Dr. Andy Cheng.  Check out our transcript here: https://bit.ly/3CZfThv  This episode was produced by Wendy Zukerman and Lexi Krupp, with help from Michelle Dang, Meryl Horn and Rose Rimler.
