NASA Falling Short of Asteroid Detection Goals

The team says it is almost certain that a large Baptistina fragment created the 180km Chicxulub crater off the coast of the Yucatan 65 million years ago. The impact that produced this crater has been strongly linked to the mass extinction event that eliminated the dinosaurs. Image from The BBC.
