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.

» Meteorite Formation Times and the Age of Jupiter

(posted August 30, 2017)

Link to article: Meteorite Formation Times and the Age of Jupiter. Isotopic analyses of meteorites and models of planetary accretion indicate that Jupiter's solid core had accreted only one million years after the Solar System began to form.

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

» Archaeology, Artifacts, and Cosmochemistry
Iron beads, identified as pieces of the Anoka meteorite, are among a small handful of artifacts made from material from the birth of the Solar System.

» Two Billion Years of Magmatism in One Place on Mars
New data from a Martian meteorite extends the time of magmatic activity by 1.8 billion years in a volcanic center that provided us a coherent group of Martian meteorites.

» Chondrules: Important, but Possibly Unfathomable
Studies of chondrules in meteorites have revealed much about them, except how they formed and if they played a role in forming planets.

» Searching for Ancient Solar System Materials on the Moon, Earth, and Mars
The early history of the Solar System is recorded by meteorites falling now, but also by those that fell hundreds of millions to billions of years ago, preserved in lunar samples, sedimentary layers on Earth, and even sitting on the surface of Mars.

» What Made the Doughnuts Inside Lunar Concentric Craters?
Concentric ridges inside small lunar craters may have formed when intrusion of magma caused uplift of the crater floor.

» Rock and Roll at the Apollo 17 Site
The latest orbital images and topographic data offer new insights to the geologic context of Apollo 17 impact melt breccias.
