Curation activities progress on the Chang’E-5 samples in France Open
China’s Chang’E-5 (CE-5) mission successfully returned 1,731 grams of lunar samples from the northeastern region of Oceanus Procellarum in December 2020 (C. Li et al., 2022; Zhou et al., 2022). The landing site, among the Moon’s youngest m…

Oued Chebeika 002: A new <span>CI1</span> meteorite linked to outer solar system bodies Open
CI1 chondrites are rare meteorites with high scientific value. In fact, they are the most chemically primitive meteorites and show evidence of intense parent‐body aqueous alteration. They also share strong similarities with samples from Ry…

Magnetization of Iron Meteorites up to the Meter in Size as Possible Analogs for Asteroid Psyche Open
Meteorite paleomagnetic studies indicate planetesimal generated magnetic fields, but spacecraft magnetic measurements have yet to identify asteroidal natural remanent magnetization (NRM). This apparent discrepancy is of particular interest…

What we can learn about Mars from the magnetism of returned samples Open
The Red Planet is a magnetic planet. The Martian crust contains strong magnetization from a core dynamo that likely was active during the Noachian period when the surface may have been habitable. The evolution of the dynamo may have played…

Estimating Paleointensities From Chemical Remanent Magnetizations of Magnetite Using Non‐Heating Methods Open
Many meteorites experienced aqueous alteration on their parent body. During this process, magnetite usually forms and acquires a chemical remanent magnetization (CRM) if growing in the presence of a magnetic field. The epoch of aqueous alt…
