NAI Member Receives Sagan Medal
G. Jeffrey Taylor from NAI’s University of Hawai’i Team is the recipient of the 2008 Carl Sagan Medal for Excellence in Public Communication in Planetary Science. The Sagan Medal, presented by the American Astronomical Society (AAS) on an (almost) annual basis, was established by AAS’s Division for Planetary Sciences to recognize and honor outstanding communication by an active planetary scientist to the general public. Recipients are scientists whose efforts have significantly contributed to a public understanding of, and enthusiasm for, planetary science.
