Mars’ atmosphere has clouds and wind just like Earth. Sometimes the wind blows the red dust into a dust storm. Spiraling dust storms–called dust devils–can look like tornadoes. Mars’ large storms sometimes cover the entire planet.
Mars is a cold desert world. The average temperature on Mars is minus 85 degrees Fahrenheit – way below freezing. It is half the size of Earth. Mars is sometimes called the Red Planet. It's red because of rusty iron in the ground.
Like Earth, Mars has seasons, polar ice caps, volcanoes, canyons, and weather. It has a very thin atmosphere made mostly of carbon dioxide, nitrogen, and argon. People would not be able to breathe the air on Mars.
There are signs of ancient floods on Mars, but now water mostly exists in icy dirt and thin clouds. On some Martian hillsides, there is evidence of liquid salty water in the ground.
Scientists want to know if Mars may have had living things in the past. They also want to know if Mars could support life now or in the future.

What does Mars look like?
This infographic uses composite orbiter images and an outline of the United States to show the scale of the Valles Marineris (a canyon system more than 2,000 miles long!). Swipe left and right to see how big this canyon system is compared to the United States.
This animated GIF was created using footage taken by NASA’s Ingenuity Mars Helicopter during its 25th flight on April 8, 2022.
This animated image blinks two versions of a May 11, 2016, selfie of NASA's Curiosity Mars rover at a drilled sample site called "Okoruso." In one version, cameras atop the rover's mast face the arm-mounted camera taking the portrait. In the other, they face away.
NASA's Curiosity Mars rover used its black-and-white navigation cameras to capture panoramas at two times of day on April 8, 2023.
