The Mars system revealed by the Martian Moons eXploration mission

open access: yesEarth, Planets and Space, 2022
Japan Aerospace Exploration Agency (JAXA) plans a Phobos sample return mission (MMX: Martian Moons eXploration). In this study, we review the related works on the past climate of Mars, its evolution, and the present climate and weather to describe the ...

Thermospheric density responses to Martian dust storm in autumn based on MAVEN data

open access: yesGeodesy and Geodynamics, 2022
The unique seasonal surface dust storms on Mars have a significant impact on the Martian atmosphere. However, due to the lack of observations, semi-empirical models are difficult to simulate the density changes in the thermosphere with the existence of ...

ESTIMATION OF AEOLIAN DUNE MIGRATION OVER MARTIAN SURFACE EMPLOYING HIGH PRECISION PHOTOGRAMMETRIC MEASUREMENTS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
At the present time, arguments continue regarding the migration speeds of Martian dune fields and their correlation with atmospheric circulation. However, precisely measuring the spatial translation of Martian dunes has been rarely successful due to the ...

The Martian Boulder Automatic Recognition System, MBARS

open access: yesEarth and Space Science, 2022
Boulder‐sized clasts are common on the surface of Mars, and many are sufficiently large to be resolved by the high resolution imaging science experiment (HiRISE) camera aboard the Mars reconnaissance orbiter. The size, number, and location of boulders on
