You might think of a "moonshot" as an actual journey to the Moon or a Mickey Mantle homerun. But at Google, the term refers to the kind of projects underway at the company's not-quite-secret lab, Google X.

"Moonshots live in the gray area between audacious projects and pure science fiction; instead of mere 10 percent gains, they aim for 10x improvements," according to Google. "The combination of a huge problem, a radical solution, and the breakthrough technology that might just make that solution possible is the essence of a Moonshot."
