Development and Evolution of Icy Layer Outcrops on Mars' North Polar Ice Cap: Observations of Vertical and Lateral Variability
Mustard, John F.; Becerra, Patricio; Bramson, Ali M. +1 more
Mars' north polar ice cap features troughs that cut into the ice, exposing subsurface layers of different brightness and topographic expression. Specifically, these layers represent two different stratum types: lower albedo (higher dust content) marker beds, which protrude out of the wall topographically, and higher albedo (i.e., icier) interbeds,…
Shallow Water Ice Detection From SHARAD Data in Central Utopia Planitia, Mars
Bugiolacchi, Roberto; Xu, Xiaoting; Xu, Yi +5 more
One of the key scientific goals of China's first Mars mission Tianwen-1 is to search for ground ice. This study focuses on investigating potential water ice reservoirs in the vicinity of the landing site of the Zhurong rover to provide geological context and references for data interpretation. Our study area is centered on Utopia Planitia (UP), wh…
Martian Atmospheric Disturbances From Orbital Images and Surface Pressure at Jezero Crater, Mars, During Martian Year 36
Hueso, R.; Sánchez-Lavega, A.; Toledo, D. +13 more
We present a study of atmospheric disturbances at Jezero Crater, Mars, using ground-based measurements of surface pressure by the Perseverance rover in combination with orbital images from the Mars Express and Mars Reconnaissance Orbiter missions. The study starts at Ls ∼ 13.3° in MY36 (6 March 2021) and extends up to Ls ∼ 30…
Atmospheric Gravity Waves in Mars' Lower Atmosphere: Nadir Observations From OMEGA/Mars Express Data
Gilli, G.; Machado, P.; Wilson, C. +6 more
We present the detection and characterization of mesoscale waves on the lower clouds of Mars (20–40 km) using hyperspectral images from the Observatoire pour la Minéralogie, l'Eau, les Glaces et l'Activité (OMEGA) onboard the European Mars Express space mission. We used image navigation and processing techniques based on contrast enhancement and g…
