Michael A'Hearn, the principal investigator for NASA's Deep Impact mission and an astronomy professor at the University of Maryland, College Park, died on May 29. He was 76.
An astronomer and professor emeritus at the University of Maryland, Dr. A'Hearn was the chief scientist for the NASA mission known as "Deep Impact," in which an impactor spacecraft was launched directly into the path of a speeding comet.

"Nothing like it had ever been attempted before," Jim Green, NASA's director of planetary science, said in an interview. What Dr. A'Hearn was proposing, Green said, was to "blow a hole" in the comet to see what was inside.

...on June 12, he is scheduled to receive posthumously NASA's Exceptional Public Service Medal.
