Wanna Save Earth?

If your thing is to save the planet, you're not alone, in fact there is a conference this week (4/15 - 4/19) of 300 scientists and NASA people who are advocating a space-telescope to locate potential asteroids nearby, and a meteor protection system to prevent potentially catastrophic meteorite strikes on Earth.  Here is a link to the live feed of the conference.  The schedule includes an April 17 talk on planetary defense featuring Bill Nye The Science Guy and Geoff Notkin of the Science Channel's Meteorite Men.
