Variability of Bright Deposits in North Polar Residual Ice Cap Craters on Mars
Abstract We use nearly a Mars decade of the Mars Reconnaissance Orbiter's High Resolution Imaging Science Experiment (HiRISE) camera observations to track surface changes in 36 small impact craters on Mars' Northern Residual Ice Cap, commonly considered to be the uppermost layer of the North Polar Layered Deposits (NPLD). Understanding the mass balance

Active Dust Devils in the Rosalind Franklin Rover Landing Site in Oxia Planum, Mars
Abstract The Rosalind Franklin rover will land in Oxia Planum, Mars, in the second half of 2030. The mission relies on solar arrays to provide electrical power to the rover, so knowledge about dust‐clearing rates is important for science operations.

Analysis of DEM combination methods using high resolution optical stereo imagery and interferometric SAR data [PDF]
Digital elevation models (DEM) from satellite data are generated mainly from two types of datasets using completely different methods: photogrammetry for optical stereo images (e.g.

Improving AquaCrop Root‐Zone Soil Moisture by Assimilating SMAP Surface Soil Moisture
Abstract Root‐zone soil moisture (RZSM) strongly controls crop development in process‐based crop models, yet most satellite missions observe only near‐surface moisture. We propose a framework to assimilate soil moisture active passive (SMAP) Level‐2 surface soil moisture retrievals into AquaCrop to improve RZSM over European croplands (0.1° resolution,

Fast Stereo Images Compression Method based on Wavelet Transform and Two Dimensional Logarithmic (TDL) Algorithm [PDF]
In this paper, a fast stereo images compression method has been proposed. In proposed method, Firstly, stereo images were transformed using Discrete Wavelet Transform (DWT) in order to reduce computation time.

Finding Novel Precursors for Solar Wind Stream Interaction Regions With Interpretable Deep Learning
Abstract Solar wind stream interaction regions (SIRs) drive recurrent geomagnetic storms, yet most existing catalogs rely on expert inspection and simple thresholds that are subjective and can miss events with complex morphologies. We present SIREN (SIR Encoder Network), a lightweight Transformer‐based model for per‐timestep SIR detection from in situ ...

Type‐III Solar Radio Bursts at Mars: A 16.5‐Year Catalog From Mars Express‐MARSIS at 0.1–5.5 MHz
Abstract The most intense radio feature in the Solar System are the solar Type‐III radio bursts, which are associated with electron beams that propagate along open magnetic field lines. Although solar radio bursts have been studied since the 1940s, observations remain mainly restricted within 1 AU.
