#2. Meteor experts Dr. Bill Cooke, Danielle Moser and Rhiannon Blaauw, all from NASA’s Meteoroid Environment Office, located at Marshall, will stay up late answering questions via Twitter. The Near-Earth Object Observations Program, commonly called "Spaceguard," discovers these objects, characterizes the physical nature of a subset of them, and predicts their paths to determine if any could be potentially hazardous to our planet.
