NASA MISSIONSExploring the Red Planet

The rovers and spacecraft we’ve sent to Mars have found evidence the planet was warmer in the past, with lakes and rivers. Was there life there? Future exploration may find evidence for that as well.

The facts and figures —37%

The gravity on Mars is only 37 percent of Earth’s gravity. Not only could you leap three times higher on Mars, but this lower gravity is one reason why Olympus Mons became the biggest volcano in the solar system.
