Review and Evaluation of Ceramic‐Stabilized Iron Oxides for Use as Energy Storage Based on Iron‐Steam Process

open access: yessteel research international, Volume 96, Issue 5, May 2025.
The iron‐steam process is an emerging technology for hydrogen production and storage, gaining attention due to its potential for sustainability and cost‐effectiveness. Developing an inexpensive and stable contact mass with maximum oxygen capacity while maintaining suitable reaction kinetics and chemical yields remains a challenge.

Do the Antennas of DEMETER Spacecraft Detect Dust Impacts?

open access: yesJournal of Geophysical Research: Space Physics, Volume 130, Issue 5, May 2025.
Abstract This study investigates pulses detected by the electric field instrument, ICE (Instrument Champ Electrique) onboard the DEMETER spacecraft. Using an automated identification algorithm, we identified 1,000 short pulses recorded in 2005 and 2010. The spatial distribution of these signals, primarily localized over South America and near the South

Mid‐Infrared Reflectance and Emissivity Spectra of High Porosity Regoliths

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 5, May 2025.
Abstract Mid‐infrared (MIR; 5–35 μm) spectroscopy is often used for mineralogical identification on planetary surfaces. Laboratory spectra aiding remote sensing observations are typically performed in reflection geometries, while MIR spectra of planetary surfaces are typically obtained via emission.

The Role of the Magnetic Field Orientation on the Variability of the Martian Topside Ionosphere Using MARSIS‐Mars Express Data

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 5, May 2025.
Abstract Mars, without a global dipole magnetic field, has its atmosphere directly exposed to the impinging solar wind, producing a complex interaction due to the remnant crustal magnetic fields, which, especially in the southern hemisphere, have spatially varying strengths and inclinations. “Mini‐magnetospheres” generated over the strong crustal field

Automatic Martian Polar Ice Cap Extraction Algorithm for Remote Sensing Data and Analysis of Their Spatiotemporal Variation Characteristics

open access: yesRemote Sensing
The detection of Martian polar ice cap change patterns is important for understanding their effects on driving Mars’s global water cycle and for regulating atmospheric circulation.

Being Martian

open access: yesDawn or Doom: The Rise and Rewards of Emerging Technologies, 2015
While long a popular place of wonder, there is now additional emphasis about spending time on Mars, if you’re a robot (Opportunity, Curiosity), a one-way ticket holder (Mars One), or an accidental resident (Mark Watney). (Statistically, it’s a good bet that Mark or one of his crew mates would have spent time in Indiana.) Whether you were fabricated in ...

Geomorphological Evidence of Near‐Surface Ice at Candidate Landing Sites in Northern Amazonis Planitia, Mars

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 5, May 2025.
Abstract This work presents geomorphological analyses of an area at the boundary between Arcadia Planitia and northern Amazonis Planitia, situated in the northern mid‐latitudes of Mars. Recent studies have indicated the presence of substantial volumes of near‐surface excess ice in Arcadia Planitia, making this region a promising candidate for future ...

MarsQE: Semantic-Informed Quality Enhancement for Compressed Martian Image [PDF]

open access: yesarXiv
Lossy image compression is essential for Mars exploration missions, due to the limited bandwidth between Earth and Mars. However, the compression may introduce visual artifacts that complicate the geological analysis of the Martian surface. Existing quality enhancement approaches, primarily designed for Earth images, fall short for Martian images due ...
