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.

» The Complicated Origin of Earth's Water

(Posted December 20, 2018)

Link to article: The Complicated Origin of Earth's Water. Water delivery and redistribution to Earth was a complicated business with hydrogen coming from chondritic and solar nebular sources.

Six recent Headline articles. The archive holds all articles in our collection.

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

» Better Know A Meteorite Collection: Fersman Mineralogical Museum in Moscow, Russia
PSRD highlights places and people around the world who play central roles in caring for and analyzing meteorites.

» The Oldest Volcanic Meteorite: A Silica-Rich Lava on a Geologically Complex Planetesimal
A volcanic meteorite is the oldest igneous meteorite identified so far, erupting onto its parent body only about 3 million years after the Solar System began to form.

» Minerals Track Chemical Reactions in Interstellar Space and in the Protoplanetary Disk
Mineral intergrowths in cosmic dust and primitive meteorites reveal processes that operated in interstellar space and in the protoplanetary disk surrounding the Sun before the planets formed.

» Meteorite Evidence for a Complicated Protoplanetary Disk
A striking dichotomy in isotopic compositions of meteorite groups appears to be consistent with Jupiter and Saturn migrating to and fro during planet formation.

In this series of reports PSRD gives quick views of big advances in planetary sciences, with links to further details. In 2019, as we approach the 50th anniversary of the Apollo 11 Moon landing (July 20, 1969) PSRD also celebrates the collection of lunar samples returned to Earth. Watch for highlights of current research and new analyses that increase our knowledge of the Moon and our Solar System.

» Early Martian Crust as Recorded by NWA 7533  -- Researchers study pyrite in Martian meteorite to investigate chalcophile and sideophile element cycling in the early Martian crust.

» Davis-Ward: The Ice That Keeps on Giving Meteorites  -- With 865 meteorites cached in the shipping crate, the 2018-2019 Antarctic Search for Meteorites (ANSMET) field team has wrapped up a successful season on the ice.
