Solar Wind Sputtering of Secondary Ions from Water-ice-covered Regolith Analogs

The Planetary Science Journal
The surfaces of airless bodies in space are constantly bombarded by solar wind and magnetospheric ions that sputter regolith grains and eject secondary particles into the exosphere.

Origin of the metal in chondritic and achondritic lithologies of the Sierra Gorda 013 СBa‐like chondrite

Meteoritics & Planetary Science
Sierra Gorda 013 (SG 013) is an unusual CBa‐like chondrite containing two texturally different, isotopically identical lithologies—chondritic (L1) and achondritic (L2), which should have a common origin.

Noble gases and nitrogen in material from asteroid Bennu

Meteoritics & Planetary Science
We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission.

Sulfur Implantation into Water Ice with Propane: Implications for Organic Chemistry on the Surface of Europa

The Planetary Science Journal
We performed experiments of implantation of energetic sulfur ions (105 keV) into 2:1 water:propane ices at 80 K and analyzed the resulting refractory organic matter with ultrahigh-resolution mass spectrometry.

The Aguas Zarcas carbonaceous chondrite meteorite: Brecciation and aqueous alteration on the parent body

Meteoritics & Planetary Science
CM chondrites are samples from primitive water‐rich asteroids that formed early in the solar system; many record evidence for silicate rock–liquid water interaction.

A diversity of temperature and pressure conditions recorded by zircon within suevite from Ries crater, Germany

Meteoritics & Planetary Science
The temperature and pressure conditions experienced by rocks during an impact event can be constrained using petrologic and microstructural analysis and is crucial to providing ground truth to the impact cratering process.
