what is the surface like on mars

The surface of Mars is cold, dry, dusty, and rocky, more like a high, polar desert on Earth than a place with beaches or forests.

Overall look and feel

  • Mars is covered in fine red dust made largely of iron-rich minerals that have rusted, giving the planet its “Red Planet” color.
  • The ground ranges from flat dusty plains to fields of rocks and boulders, with lots of impact craters of different sizes.
  • The air is very thin and dry, so there is no liquid water on the surface today, only ice and vapor.

Major landforms

  • Vast plains and ancient highlands: The southern hemisphere is dominated by old, heavily cratered highlands, while the north has smoother, lower plains that may once have held oceans.
  • Huge canyon systems: Valles Marineris is a giant canyon system over 4,000 km long and up to 7 km deep, dwarfing Earth’s Grand Canyon.
  • Giant volcanoes: Mars hosts enormous shield volcanoes like Olympus Mons, about 22 km high, the tallest known volcano in the solar system.

Ground texture underfoot

  • Much of Mars is loose dust and sand that can form dunes, ripples, and dust devil tracks shaped by the wind.
  • In many places, the dust is thin and you would find hard volcanic rock or bedrock just beneath it.
  • There are regions with layered rocks, cliffs, and “chaos terrain” where the surface looks broken and jumbled, hinting at past flooding or ice movement.

Ice, frost, and past water

  • The polar caps are made mainly of frozen carbon dioxide with underlying water ice, and seasonal frost can coat the ground in winter.
  • Many valleys, channels, and layered sediments suggest that liquid water once flowed on the surface long ago, carving river-like features and depositing minerals that form only in water.
  • Glacial-like features and buried ice have been found around mesas and in some valleys, showing that ice still shapes parts of the surface today.

What it would be like to stand there

  • The sky would look butterscotch or hazy, and the Sun would appear smaller than on Earth because Mars is farther away.
  • Under your boots, you’d likely have a mix of soft dust and gritty sand with scattered rocks, in an environment that is extremely cold, almost airless, and constantly exposed to radiation.
