Watching Space Rocks: Live Chat With NASA's Asteroid Trackers

A live videocast and chat from NASA's Jet Propulsion Laboratory, Pasadena, Calif., offers a
unique opportunity for viewers to ask questions of scientists with NASA's Near-Earth Object
Program Office about how NASA discovers and tracks asteroids.

The live event will air on the "NASAJPL" channel available on Ustream TV at:
http://www.ustream.tv/channel/nasajpl on March 25 at 4:30 p.m. PDT (7:30 p.m. EDT and 23:30
UTC).

NASA detects and tracks asteroids and comets passing close to Earth. The Near-Earth Object
Observation Program, commonly called "Spaceguard," discovers, characterizes and computes
trajectories for these objects to determine if any could be potentially hazardous to our planet.

Participants include:
* Don Yeomans, manager, NASA's Near-Earth Object Office at JPL
* Steve Chesley, scientist, NASA's Near-Earth Object Office at JPL
* Paul Chodas, scientist, NASA's Near-Earth Object Office at JPL

If you are unable to take part in the live chat, you can submit questions in advance to
chatquestion@jpl.nasa.gov and watch the archived video at a later time.
