Dust Lifting and Deposition Over Six Mars Years at Gale Crater, Mars, From REMS Observations and Mesoscale Simulations

Journal of Geophysical Research: Planets, Volume 130, Issue 6, June 2025.
Abstract We present the temporal evolution of the effect of dust accumulation on two surfaces of the Curiosity rover at Gale crater during almost 4,000 sols using Rover Environmental Monitoring Station (REMS), Chemcam and Mastcam observations, and compare it with simulations of the Mars Weather Research and Forecasting Model (MarsWRF) atmospheric ...

Collection and In Situ Analyses of Regolith Samples by the Mars 2020 Rover: Implications for Their Formation and Alteration History

Journal of Geophysical Research: Planets, Volume 130, Issue 2, February 2025.
Abstract The Perseverance rover has sampled mm‐size lithic fragments containing olivine likely from at least two source regions from the surface of an inactive megaripple surface, and fine‐grained material from the surface and to a depth of ∼4–6 cm. Some of the mm‐size grains lack a coherent diffraction pattern measured by PIXL, consistent with the ...

WindSightNet: The Inter‐Annual Variability of Martian Winds Retrieved From InSight's Seismic Data With Machine Learning

Journal of Geophysical Research: Planets, Volume 130, Issue 2, February 2025.
Abstract Wind measurements from landed missions on Mars are vital to characterize the near surface atmospheric behavior on Mars and improve atmospheric models. These winds are responsible for aeolian change and the mixing of dust in and out of the atmosphere, which has a significant effect on global circulation.

Diurnal and Seasonal Variations of Gravity Waves in the Lower Atmosphere of Mars as Observed by InSight

Journal of Geophysical Research: Planets, Volume 130, Issue 2, February 2025.
Abstract We investigate Gravity Waves (GWs) in the lower atmosphere of Mars based on pressure timeseries acquired by the InSight lander. We compile a climatology showing that most GW activity detected at the InSight landing site takes place after the sunrise and sunset; they are almost absent during the aphelion season, and more prominent around the ...

Martian Atmospheric Disturbances From Orbital Images and Surface Pressure at Jezero Crater, Mars, During Martian Year 36

Journal of Geophysical Research: Planets, Volume 130, Issue 1, January 2025.
Abstract 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.

Iridescence Reveals the Formation and Growth of Ice Aerosols in Martian Noctilucent Clouds

Geophysical Research Letters, Volume 51, Issue 23, 16 December 2024.
Abstract Water and carbon dioxide each form mesospheric clouds on Mars. At such altitudes (40–100 km), clouds may remain sunlit for part of the night. We describe a previously unreported, visually spectacular season of iridescent, noctilucent clouds visible in early southern autumn from the Curiosity rover's site in Gale crater.

Astrobiologia e sua importância no entendimento da origem e evolução da vida

Research, Society and Development, 2020
A “origem da vida” e “estamos sozinhos no Universo’ sempre foram incógnitas para a comunidade científica e para grande parte da população. A astrobiologia é uma área recente que busca entender como a vida se originou e evoluído durante esses bilhões de anos de existência do Cosmo.
