Planetary scientists sharing ideas and discoveries.
Planetary Science Research Discoveries (PSRD) is an educational site sharing the latest research by NASA-sponsored scientists on meteorites, asteroids, planets, moons, and other materials in our Solar System. The website is supported by the Cosmochemistry Program of NASA's Science Mission Directorate and by Hawai'i Space Grant Consortium and is a vital link for planetary and space sciences, and for learning how science works.
Supported by NASA's SMD Cosmochemistry Program and Hawai'i Space Grant Consortium.

LINKS OPEN IN A NEW WINDOW. Congratulations to Harry (Hap) Y. McSween Jr., recipient of the 2012 J. Lawrence Smith Medal awarded by the National Academy of Sciences (NAS). Hap, Chancellor's Professor and Distinguished Professor of Science at the University of Tennessee, is being honored for his pioneering studies of the igneous and metamorphic histories of the parent planets of the chondritic and achondritic meteorites, with particular emphasis on his work on the geological history of Mars based on studies of Martian meteorites and spacecraft missions to the planet. The medal and prize of $25,000 are awarded every three years for original and meritorious investigations of meteoric bodies. This award was established as a gift from Sarah Julia Smith in memory of her husband and has been presented since 1888. Hap, along with 16 others who have made major contributions to science, will be recognized in a ceremony on April 30, during the National Academy of Sciences' 149th annual meeting.

[Posted 23 Jan 2012.] Asteroid Vesta is likely cold and dark enough for water ice to exist beneath the surface, according to new reports in the January 2012 issue of the journal Icarus. Read more from NASA's Dawn Mission News. [Posted 26 Jan 2012.] In this series of articles PSRD highlights the essential tools and amazing technology used by talented scientists seeking to unravel how the solar system formed. This section of PSRD contains annotated slide sets that are associated with our articles. We hope you find the slides useful for your own talks and presentations. This section of PSRD contains links to further information about meteorites, planetary science, and classroom activities.
