Origin of Long‐Wavelength Variations in Crustal Thickness on Rocky Planets

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Long‐wavelength crustal thickness variations are observed on telluric planets, particularly on Mars and the Moon whereas Mercury appears to lack such variations. They may stem from two early‐stage positive feedback mechanisms that can emerge in stagnant‐lid planets.

Direct Detection of Hydrogen Reveals a New Macroscopic Crustal Water Reservoir on Early Mars

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The next great leap in Martian exploration is the return of samples to Earth. Maximizing their scientific value requires non‐destructive analytical techniques for early three‐dimensional characterization. Neutron computed tomography (CT), highly sensitive to hydrogen, complements conventional X‐ray CT and enables the detection of hydrous ...

Corundum Discovered by SuperCam and the Perseverance Rover at Jezero Crater, Mars

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract Mars is primarily composed of mafic mineral assemblages and their alteration products, but small, scattered rocks strewn across the landscape offer clues to greater petrological diversity. While traversing the Jezero crater rim, the Perseverance rover encountered several plagioclase‐rich light‐toned float rocks.

Accelerating Nature: Induced Atomic Order in Equiatomic FeNi

Advanced Science
The production of locally atomically ordered FeNi (known by its meteoric mineral name, tetrataenite) is confirmed in bulk samples by simultaneous conversion X‐ray and backscattered γ‐ray 57Fe Mössbauer spectroscopy.
