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. With original support from the Planetary Science Division of NASA's Science Mission Directorate and Hawai'i Space Grant Consortium, this site is a vital link for planetary and space sciences, and for learning how science works.

Enlightening Inquisitive Minds

Welcome to the PSRD website, a place to learn about the fascinating discoveries being made by planetary scientists. What are we finding out about the building blocks of planets and the building blocks of life? What's in an asteroid, in stardust, in a comet? Here you can discover for yourself the excitement of doing science and finding answers to these and more questions, through the eyes of today's researchers. We take to heart NASA's emphasis on communication and education. A goal of this website is "Educational Excellence," specifically, to "... inspire America's students, create learning opportunities, and enlighten inquisitive minds." We explore the science questions that researchers are actively pursuing, and explain how the answers are discovered and what they mean.

PSRD is a dynamic website covering hot topics in cosmochemistry and planetary sciences. Cosmochemistry is an interdisciplinary science that overlaps with geochemistry, geology, astronomy, astrophysics, and geophysics to discover the materials and fundamental processes in the solar nebula and our Solar System. These sciences give us complementary ways of looking at our origins by addressing questions such as, How did the Sun and planets form? Where did we come from? Cosmochemistry is a careful examination of the building blocks of the cosmos, and will play an important role in our ability to develop local resources on the Moon, Mars, and asteroids, essential to sustained human presence in space.

The PSRD website features Headline articles illustrated with graphics and animations, pdf versions for easier printing, short slide summaries of articles, CosmoSparks reports, a comprehensive archive, news links, glossary, search engine, subscription service, social-media sharing links, and comments page. The Headline article of the month is shown on our homepage and all the articles and reports from our entire collection are available in the archive. Use the navigation links on the page tops or bottoms to move throughout the website.

We began working on PSRD in September, 1996 and the first articles were posted in October, 1996. We gratefully acknowledge original support from NASA's Planetary Science Division's Cosmochemistry Program for funding our first 20 years and Emerging Worlds Program for four years. We gratefully acknowledge Hawai'i Space Grant Consortium for original and ongoing support. This is an active project and additional resources are added as needed.


Who We Are

Development, operation, content, and overall editorial management of the PSRD website are provided by cofounders G. Jeffrey Taylor and Linda M.V. Martel, planetary geoscientists.

Jeff Taylor is the recipient of the 2008 Carl Sagan Medal awarded by the Division for Planetary Sciences (DPS) of the American Astronomical Society—for excellence in public communication of planetary science. See the SOEST Press Release for more details about this wonderful honor.

Jeff also received the 2011 Shoemaker Distinguished Lunar Scientist Award, presented by the NASA Lunar Science Institute—in recognition of his significant scientific contributions and leadership roles.

Linda Martel is the recipient of the 2018 Service Award presented by the Meteoritical Society—for advancing the Society's goals of promoting research and education in meteoritics and planetary science in ways other than by conducting scientific research, i.e. this PSRD website.

Jeff Taylor and Ron Fodor are coauthors of IMPACT! a Kindle eBook novel that tells a story centering around the threat of an Earth-crossing asteroid.

Submission Guidelines for Contributors

PSRD website is open to all who wish to contribute an article suited for the interdisciplinary nature of planetary science with appropriate connections to cosmochemistry. PSRD provides a forum for NASA-funded scientists to fulfill their outreach responsibilities. A key requirement is that PSRD articles are based on scientific work published in recognized, peer-reviewed journals. This excludes newsletters or highly-biased publications as eligible sources. PSRD articles are reviewed by appropriate researchers prior to publication.

Additionally, Dwornik Student Paper and Poster award winners are invited to submit an article based on their award-winning presentations. These student research projects receive recognition at the Lunar and Planetary Science Conference (held each March in Texas) after careful review and judging by a panel of planetary geoscientists.

Articles should be written in English for a general audience, with a minimum of scientific jargon. If you need to use technical language, we'll add the terms to our ever-expanding glossary. Write it in the first person. Feel free to add something about your motivation for doing the work. Articles should not exceed about five pages (single-spaced). Begin the article with a one-paragraph summary of the theme and main points. We prefer images and graphics submitted in electronic formats, but prints suitable for electronic scanning are acceptable. All images or graphics may be resized at the discretion of the editors. Images and graphics used in PSRD articles or reports will be fully credited to, and will remain the property of, the contributor. PSRD may also produce additional graphics in consultation with the author.
