An accurate assessment of the bulk chemical composition of Mars is fundamental to
understanding planetary accretion, differentiation, mantle evolution, the nature of the …

Many studies exist on magmatic volatiles (H, C, N, F, S, Cl) in and on the Moon, within the
last several years, that have cast into question the post-Apollo view of lunar formation, the …

The Perseverance rover landed in Jezero crater, Mars, in February 2021. We used the
Scanning Habitable Environments with Raman and Luminescence for Organics and …

The distribution of water in the Moon's interior carries implications for the origin of the Moon,
the crystallization of the lunar magma ocean and the duration of lunar volcanism. The …

The first samples collected by the Mars 2020 mission represent units exposed on the Jezero
Crater floor, from the potentially oldest Séítah formation outcrops to the potentially youngest …

Martian meteorites are the only direct samples from Mars, thus far. Currently, there are a total
of 262 individual samples originating from at least 11 ejection events. Geochemical …

Reconciling the geology of Mars with models of atmospheric evolution remains a major
challenge. Martian geology is characterized by past evidence for episodic surface liquid …

Context. The formation of planetesimals in protoplanetary disks is not well-understood.
Streaming instability is a promising mechanism to directly form planetesimals from pebble …

The hydrogen-isotope [deuterium/hydrogen (D/H)] ratio of Earth can be used to constrain the
origin of its water. However, the most accessible reservoir, Earth's oceans, may no longer …

Return of samples from the surface of Mars has been a goal of the international Mars
science community for many years. Affirmation by NASA and ESA of the importance of Mars …
