Moon Record Analysis Challenges Impact Origin Of Earth’s Water
A long-standing idea in planetary science is that water-rich meteorites arriving late in Earth’s history could have delivered a major share of Earth’s water. A new study argues that the […]
Contaminants, Including Ink, Detected In Meteorites Suggest Sample Preparation Needs Improving
Several contaminants, including traces of ink, originating in the preparation of subsamples, have been identified in Martian meteorites by the EHU’s research group. The finding highlights the importance of stricter […]
Chang’e Mission Samples Reveal How Exogenous Organic Matter Evolves On The Moon
Elements essential to life, such as carbon, nitrogen, oxygen, phosphorus, and sulfur, were “delivered” to the Earth and Moon during the early stages of the Solar System via asteroids and […]
First Lunar Farside SETI Observations for Periodic Signals With The Low-frequency Radio Spectrometer Of Chang’E-4 Mission
Chang’E-4 (CE4), the first mission to soft-land on the lunar farside, provides a unique opportunity for astronomical observations from an environment shielded from terrestrial radio interference, and thus serves as […]
Legged Robot Could Accelerate Resource Prospecting On The Moon And The Search For Life On Mars
Planetary surface missions currently operate cautiously. On Mars, communication delays between Earth and rovers (typically between four and 22 minutes), as well as data transfer constraints due to uplink and […]
LEAG-ExMAG Artemis Sample Return SAT Reports Now Available
The Lunar Exploration Analysis Group (LEAG) and Extraterrestrial Materials Analysis Group (ExMAG), were requested and empowered by NASA’s Science Mission Directorate (SMD) and Planetary Science Division (PSD) to establish a […]
Foundational Artificial Intelligence for the Moon and Mars (FAIMM) Webinar
On Monday, February 23, 2026 at 12 pm Eastern Time, the planetary science division will host a webinar overview of program element C.12 Foundational Artificial Intelligence for the Moon and […]
Artemis II’s Possible Impact on JWST Science Operations
January 23, 2026 NASA has recently begun preparations for the Artemis II mission, which will send four astronauts on a journey around the Moon. The Artemis missions share the Deep […]
Our Moon’s 4-Billion-Year Impact Record Suggests Meteorites Didn’t Supply Earth’s Water
A long-standing idea in planetary science is that water-rich meteorites arriving late in Earth’s history could have delivered a major share of Earth’s water. A new study by Universities Space […]
