A Steady Hand
The Moon is more than a pretty accessory in our night sky. It stabilizes Earth's wobble, which led to a more stable climate and probably helped life evolve. The Moon also guides the ebb and flow of Earth's oceans.

Free Moon
Astronauts planted six American flags on the Moon, but that doesn't mean the United States owns it. An international law written in 1967 prevents any single nation from owning planets, stars or any other natural objects in space.

Flip Side
Humans have studied the Moon for thousands of years, but we didn't see its far side until a spacecraft got there 1959. That's because the Moon rotates once on its axis in about the same time it orbits Earth. That means the same side faces Earth at all times.
