Modern technology, including orbiters, landers, and rovers, helps scientists explore and study Mars' geology.

Front

Martian dust storms are known for covering the entire planet.

Back

Dust storms on Mars can grow so large that they envelop the entire planet, lasting for weeks or months.

Front

Mars' surface features include canyons, volcanoes, and evidence of ancient water flow.

Back

The surface of Mars is marked by geological features such as Valles Marineris, Olympus Mons, and dried riverbeds.

Front

Mars' red color is due to the oxidation of iron in its soil.

Back

The iron in Mars' soil reacts with oxygen, creating iron oxide (rust), which gives the planet its red hue.
