The Pellas-Ryder Award, jointly sponsored by the Meteoritical Society and the Planetary Division of Geological Society of America, is for undergraduate and graduate students who are first author of a planetary science paper published in a peer-reviewed scientific journal. Any first author of a paper published on a topic listed on the cover of Meteoritics and Planetary Science who was a student when the paper was submitted is eligible for consideration for the award.
Members are strongly urged to nominate candidates for the Pellas-Ryder Award. Yearly nomination deadline: January 31. The procedures for nominations may be found in the Pellas-Ryder Award Committee bylaws and rules.
