Don Yeomans is one of the reasons we can all sleep a little better at night. For over a decade, Don and I have been hunting for incoming asteroids that come too close to earth. Every night, telescopes make thousands of asteroid observations which go to Don's premier team at the Jet Propulsion Laboratory, where that data is converted into information about the trajectory of the rocks years or even decades into the future. One day, without question, it will be Don and his team to issue a warning to the world that it's time to launch a deflection campaign to prevent an incalculable disaster. We know how things worked out for the dinosaurs. It takes a levelheaded leader like Don to spare us their fate.
