Lunar exploration is once again in full swing. Japan’s Kaguya and India’s Chandrayaan-1 satellites are currently in orbit around the moon. China’s Chang’e spacecraft, after a successful mission, has been intentionally crashed on the moon. And the United States’ Lunar Reconnaissance Orbiter is preparing to launch. These are all unmanned missions; humans haven’t been to the moon in more than 30 years. But we will probably return in the next decade, and when we do, we hope to dig even deeper to uncover the moon’s secrets.
