Scientists Make Plans To Blast Threatening Asteroids

The recent meteor blast in Russian has brought renewed public attention to the risk posed by meteors on a collision course with the earth. It's a risk Dr. Andrew Cheng of the John Hopkins Applied Physics Lab is working to avert. In a joint venture with NASA and the European Space Agency, Cheng is heading up a plan to develop a rocket that could collide with an asteroid and knock it off course. He talks about it with Weekends on All Things Considered host Jacki Lyden.
