The Evolution of Autonomous Systems for Planetary Cave Exploration: A Review
Journal of Field Robotics, Volume 43, Issue 6, Page 4094-4115, September 2026.ABSTRACT The exploration of Subsurface Access Points (SAPs), such as lava tubes on the Moon and Mars, has gained significant interest due to their potential as stable environments shielded from surface radiation and temperature extremes. These sites are considered high‐value targets for detecting water and signs of ancient life, and assessing their ...

A Low‐Power Radioisotope XRF Spectrometer for Detection of Light Elements on Planetary Missions
X-Ray Spectrometry, Volume 55, Issue 5, Page 721-729, September/October 2026.ABSTRACT Current X‐ray spectrometers for in situ geochemical analysis on planetary missions typically rely either on X‐ray tubes, which demand electrical power and add mass and thermal complexity, or on alpha particle X‐ray spectrometers (APXS) that use rare 244 Cm sources, and come with severe concerns on radiation safety and isotope availability.

Electron Shot Noise on a Current Biased Antenna
Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.Abstract The Parker Solar Probe (PSP) Fields Experiment (FIELDS) uses Radio Frequency Spectrometer (RFS) data and Quasi‐Thermal Noise Spectroscopy (QTN) to determine the temperature and density of electrons in the heliosphere. The FIELDS antennas typically operate with a negative bias current.

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.
