Mars and Earth: The similarities

Mars and Earth: The similarities

Everything we've learned about Mars over the last century suggests that the planet was once able of hosting ecosystems.

  • Mars is just over half the size of Earth.
  • Gravity is only 38 percent than that of Earth's.
  • It rotates around its axis at about the same speed as Earth, meaning that a day on Mars is just 40 minutes longer than on Earth.
  • One year on Mars takes about 687 Earth days.
  • Mars has the same amount of habitable surface as Earth. It also contains ice on the polar caps.

But Mars is wrapped in a thin carbon dioxide atmosphere and cannot support earthly life forms.
