Benjamin Dean Lecture: Near-Earth Objects: Finding Them Before They Find Us

Of all the natural disasters that could befall us, only an Earth impact by a large comet or asteroid has the potential to end civilization in a single blow. Yet these near-Earth objects also offer tantalizing clues to our solar system's origins, and someday could even serve as stepping-stones for space exploration. Donald Yeomans introduces the public to the science of near-Earth objects-its history, applications, and ongoing quest to find near-Earth objects before they find us.

Speaker: Dr. Donald Yeomans, NASA Jet Propulsion Laboratory
