Planetary Science Research Discoveries

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 Planetary Science Division 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.

RECENT HEADLINE ARTICLES.         [  V I E W     A L L  ]

» Scientific Discoveries from the Apollo 11 Mission
The Apollo 11 mission showed that the Moon formed hot, that it was magmatically active for at least 800 million years, and that the surface-blanket of dusty rubble contains a treasure trove of evidence of how the Moon formed.

» Lunar Samples Collected Up There and Down Here
Apollo lunar samples and lunar meteorites help us understand not only the Moon and Earth, but also fundamental processes in our Solar System.

» Recipe for Making H2O in the Lunar Regolith: Implant Solar Wind Hydrogen and Heat with Micrometeorite Impacts
Laboratory experiments simulating space weathering on the Moon show that water can be produced by rapid heating caused by micrometeorite impacts on grains implanted with hydrogen from the Sun.

» Active Asteroids
Researchers document the stunning effects of disintegrating asteroids to learn more about their dusty debris tails and the processes causing them to happen.
