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.

| 31 MAR 10 | Dynamics and Chemistry of Planet Construction by G. Jeffrey Taylor Outward migration of Saturn might have triggered a dramatic increase in the bombardment rate on the Moon 3.9 billion years ago, an idea testable with lunar samples. |
|
| 24 AUG 06 | Wandering Gas Giants and Lunar Bombardment by G. Jeffrey Taylor Outward migration of Saturn might have triggered a dramatic increase in the bombardment rate on the Moon 3.9 billion years ago, an idea testable with lunar samples. |

| 25 NOV 02 | Bands on Europa by Linda M. V. Martel Rifting at Earth's mid-ocean ridges is a good analogy for Europan band formation. |
|
| 21 AUG 01 | Uranus, Neptune, and the Mountains of the Moon by G. Jeffrey Taylor The tardy formation of Uranus and Neptune might have caused the intense bombardment of the Moon 3.9 billion years ago. |
|
| 26 FEB 01 | The Europa Scene in the Voyager-Galileo Era by Linda M. V. Martel Voyager and Galileo images provide a 20-year perspective on the geology of Europa's water-ice surface. |
|
| 15 FEB 00 | Jupiter's Hot, Mushy Moon by G. Jeffrey Taylor Very high lava flow temperatures on Io lead some scientists to propose that the satellite's interior is a swirling cauldron of partially molten rock. |
|
| 24 SEPT 98 | Europa's Salty Surface by G. Jeffrey Taylor Jupiter's moon Europa has salt deposits on its surface that may be the products of evaporation of water erupted from an ocean beneath the satellite's icy crust. |
|
| 27 APR 98 | Big Mountain, Big Landslide on Jupiter's Moon, Io by Linda M. V. Martel Thrust faulting and uplift of a large block of Io's crust may have created a mountain and the landslide on it. |
