Diurnal and Seasonal Variations of Clouds in the Tharsis Montes Region of Mars Using the Emirates eXploration Imager (EXI) Observations [#2250]
The objective of this study is to provide a catalog of the life cycle of clouds in the volcanic region (Olympus and Arsia Mons) observed by EXI for Mars year 36.

Golombek M.* Charalambous C. Newman C. Williams N. Baker M. et al.
Lifting Dust on Mars: Results from the InSight Solar Array Cleaning Experiments [#2467]
InSight performed the first semi-controlled in situ experiments on Mars that support sand impacting the surface as a means to lift dust into the atmosphere.
8:55 AM
Charalambous C.* Golombek M. P. Pike W. T. Lemmon M. Spiga A. et al.
Thresholds for Wind-Driven Sediment Transport at InSight, Mars [#2210]
We present findings on seasonality and thresholds for sand motion on Mars by investigating aeolian activity over two martian years with InSight’s rich dataset.
9:05 AM
Panel Q&A
9:25 AM
Vicente-Retortillo A.* Lemmon M. T. Martínez G. M. Toledo D. Apéstigue V. et al.
Dust Accumulation from MEDA Measurements at Jezero Crater, Mars [#1969]
We show the evolution of dust accumulation from Mars 2020 measurements, derive accumulation and removal rates and compare with other instruments and missions.
9:35 AM
Herkenhoff K. E.* Sullivan R. J. Newman C. E. Paar G. Baker M. et al.
Comparison of Ventifact Orientation and Recent Wind Direction Indicators on the Floor of Jezero Crater, Mars [#1525]
We will report orientation measurements of ventifact textures on the floor of Jezero and compare them with orientations of recent wind direction features.
9:45 AM
Mimoun D.* Gillier M. Murdoch N. Stott A. Petculescu A. et al.
Acoustic Measurements of the Near Surface Mars Environment [#1459]
Since the Perseverance landing a SuperCam microphone has been recording a vast variety of sounds, painting the picture of the near-surface Mars acoustic environment.
9:55 AM

Comprehensive Statistical Analyses and Data-Driven Modeling of Electron and Proton Auroras on Mars Using EMM and MAVEN Observations [#2083]
We perform comprehensive statistical analyses of aurora observations to understand the processes responsible for the varied auroral activity on Mars.
10:35 AM
Jackson B.*
Estimating Aerodynamic Properties of Planetary Surfaces Using Drone Attitude [#1293]
Tilting in the breeze / A drone groks the wind profile / Mars drone prob’ly has.
