Did You Know?
With about 1/3 the gravity of Earth, anyone on Mars could dunk a basketball in a regulation goal. But the required spacesuit might cut down on your edge.
The highest mountain in the galaxy is found in Mars. Olympus Mons is a shield volcano that is three times the height of Mount Everest. It has a height of nearly 25km and a diameter of 600km.
