What do the discovery of close fly by asteroid 2012 DA14 and the most productive near Earth object (NEO) follow-up tracking program in the world have in common? They were both made possible by Planetary Society Shoemaker NEO Grants. And, now, we again invest in the future and defending against the asteroid threat to Earth. NEO Shoemaker Award winners for 2013 announced.

Bill Nye

The Administration just released its proposed budget for 2014 and it contains some very bad news for NASA's planetary exploration program. Just three weeks ago the U.S. Congress rejected similar cuts proposed for planetary exploration last year. It was a clear statement of support by both Congress and the public: planetary exploration is an affordable national priority.
