Visible‐Shortwave Infrared (VSWIR) Spectral Parameters for the Lunar Trailblazer High‐Resolution Volatiles and Minerals Moon Mapper (HVM3)

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract The Lunar Trailblazer smallsat mission High‐resolution Volatiles and Minerals Moon Mapper (HVM3) science instrument was designed to acquire targeted spectral image cubes of the lunar surface at visible to shortwave infrared (VSWIR) wavelengths (0.6–3.6 μm) in an effort to understand the distribution, abundance, and form (OH, H2O, ice) of lunar

KAUSTSat: Saudi Arabia's First Hyperspectral CubeSat Mission for Earth Observation

Earth and Space Science, Volume 13, Issue 3, March 2026.
Abstract Developed by the King Abdullah University of Science and Technology (KAUST) to support research in atmospheric science and remote sensing, KAUSTSat represented Saudi Arabia's (and the Middle East's) first research‐focused hyperspectral CubeSat mission for Earth observation.

Short‐Term Estuarine Phytoplankton Dynamics in Response to Hurricanes Along the Gulf Coast of America: A Variational Autoencoder (VAE) Approach With Satellite and Bio‐Optical Observations

Journal of Geophysical Research: Oceans, Volume 131, Issue 3, March 2026.
Abstract Hurricanes drive diverse estuarine phytoplankton responses and can trigger cascading ecological and physicochemical impacts. Capturing these short‐term dynamics requires high spatiotemporal resolution. Here, we applied a globally‐applicable coastal ocean color algorithm, Variational Autoencoder (VAE), to Sentinel‐2 MSI imagery for chlorophyll ...

Shortwave Infrared Microimaging Spectroscopy of the Martian Meteorites

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Until samples from the Martian surface are successfully brought to Earth, meteorites represent the only opportunity to perform laboratory analyses on Martian material. Microimaging spectroscopy of the Martian meteorite suite provides a valuable means to better understand infrared data collected remotely from the Martian surface. This rapid and

Mesoscale Stationary Features in the Dayside Clouds of Venus

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract We present new detections of mesoscale stationary features, which are interpreted as gravity waves, on the dayside clouds of Venus. These come from an analysis of images from two instruments onboard different spacecrafts: Visible and InfraRed Thermal Imaging Spectrometer—Mapper (VIRTIS‐M) on Venus Express (VEx) and IR2 on Akatsuki.

Mineralogical Classification of CRISM Hyperspectral Data Under Uncertainty With Hybrid Neural Networks

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract Orbital remote sensing observations are a lynchpin of planetary science research. Hyperspectral infrared spectroscopy in particular is key for planetary mineralogical exploration, for example, CRISM for Mars, as this underpins our understanding of the distribution of specific lithologies and the geological process leading to their formation ...

Exploring Terrestrial Lava Tubes as Martian Analogs (I): Multi‐Analytical Study of Mineralization Processes in Cueva del Vidrio, La Palma (Canary Islands)

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.
Abstract The study of terrestrial lava tubes is essential for understanding geological processes occurring during volcanic activity on other planetary bodies, such as Mars. These processes lead to the formation of minerals analogous to those found on other planets.

Capturing Spatial Gradients of Water Color and Clarity in Subtropical Reservoirs During Drought

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract Reservoirs have spatial variation in water depth, suspended matter, and biogeochemistry that can influence patterns of water clarity and color. Spatial surveys with sensor‐equipped boats matched in time with satellite image acquisition provide data‐intensive avenues for understanding spatial patterns of optical properties within reservoirs. We

Double‐Peaked Hyperspectral Features at 710 and 800 nm for Monitoring Coastal Chlorophyll‐α Concentrations From Space

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 3, March 2026.
Abstract The concentration of chlorophyll‐α $\alpha $ has been estimated from sea color, primarily based on the reflectance ratio between the blue and green spectral bands in multiband images obtained by satellite optical sensors. However, this method is only effective in open, clear water and cannot be reliably applied to shallow coastal waters.

Monitoring Flood Inundation Dynamics From Space

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract With the increasing intensity and frequency of flood events worldwide, the need for accurate and timely inundation mapping has never been more critical. Large‐scale flood extent estimations are vital for coordinating effective disaster response, facilitating recovery, and building future resilience.
