what are the risks of dust and sand on mars

Dust Storms Health Impacts

Dust storms are natural events that occur when heavy winds blow loose sand, dirt and other fine particles from deserts and semi-arid landscapes into urban areas. Dust storms may have adverse effects on your health and is especially harmful for people who already have breathing-related difficulties.

Although the Arrako mutants invite the challenge of such elements, Dust has been tasked with controlling the dust storm and preventing it from decimating the newly constructed alien embassies. Wrestling the storm in her own sand form, Dust is able to seemingly get it under control -- even impressing Legion, who is often somewhat detached by choice.

The rover's battery is powered by harnessing the Sun's energy through its solar panels, but these are thought to be covered in Mars dust, which is hampering how much energy they can absorb. In February, its solar panels were reportedly producing just 27 per cent of their expected energy capacity.

In this way, Mars is more similar to Earth than you might expect. On the Red Planet, strong winds whip dust and sand from the surface into a frenzy, moving it across the planet at high speeds. These winds can hit 100 km/h, enough to create giant dust storms that settle across huge swathes of Mars, lasting for many days or even weeks.

The Science of Plume Effects - Center for Lunar & Asteroid Surface Science

The idea is that gas diffuses into the soil between the grains of sand and dust, building up pressure to match the pressure of the rocket exhaust on top of the soil. Then, it can erupt in two different ways. One way is that it diffuses laterally under the surface of the soil, building up pressure away from the centerline of the rocket.
