Feature Detection Onboard Mars Rovers: Automated Cloud and Dust Devil Detection
Introduction: Recent explorations on the Martian surface have revealed an environment far more dynamic than previously believed. In particular, the atmosphere of Mars is very dynamic. Dust devils and clouds are dynamic atmospheric features that have been observed by the Mars Exploration Rovers (MER). These high science value events have been the subject of considerable study. Both dust devil an...
متن کاملMars: Dust Devil Tracks in Hellas Basin and Argyre Planitia
Introduction: Dust devils on Mars could be an important mechanism for delivery of dust into the Martian atmosphere. Suspended dust in the Martian atmosphere is observed to be ~1-2μm in diameter [1,2,3] and calculations of fall-out rate [4,5] imply an ongoing supply of this fine dust to the atmosphere. Laboratory wind tunnel experiments [6,7], however, suggest that entrainment of fine dust into ...
متن کاملIrregular dust devil pressure drops on Earth and Mars: Effect of cycloidal tracks
In a survey of dust devil activity at a desert playa using continuous monitoring by a pressure logger, we have detected a number of pressure drops with complex structures: simple and symmetric drops make up only 25–30% of the total. In contrast to the simple, symmetric single-dip profiles expected for singlecell vertical vortices gliding past the pressure sensor, many profiles have an asymmetri...
متن کاملDust “ Drifts ” on Mars
Introduction: Eolian sedimentary deposits are important because they provide a record of the direction and strength of winds on Mars and the type and flux of sediments transported by the winds. While Martian sand dunes and transverse aeolian ridges ("TARs") have been thoroughly studied, the sedimentary deposits left behind by blowing dust have received comparatively little attention to date. Wi...
متن کاملTropical Dust Cyclones on Mars
Introduction: Atmospheric dust plays an important role in regulating the climate of Mars and strongly influences the deposition of incoming solar energy and outgoing infrared radiation, thereby affecting atmospheric dynamics through heating. The lifting of dust from the surface is fundamentally a result of atmospheric circulations, and this provides an opportuntity for feedback between atmosphe...
