Elon Musk wants humans to live on other planets one day. But he's worried about the cost of getting there. So in 2002, he took the fortune he made in Internet start-ups and started his own rocket company. He called it SpaceX.

The company is still in its early days. It's had seven launches, four of which made it into orbit. According to the company's website, the price to put stuff in orbit runs around $2,000 to $3,000 per pound.

Musk says SpaceX's latest rocket in development, the Falcon Heavy, will be able to do it for as little as $1,000 a pound.

Unused dollar coins have been quietly piling up in Federal Reserve vaults in breathtaking numbers, thanks to a government program that has required their production since 2007.

And even though the neglected mountain of money recently grew past the $1 billion mark, the U.S. Mint will keep making more and more of the coins under a congressional mandate.

The Comedian Who Ran For Mayor

Jon Gnarr is an absurdist Icelandic comedian. Last year, he ran for mayor of Reykjavik. Like most absurdist comedians, he had no political experience.

"I just invented a new political party," he says. "I was not drunk or anything."

Gnarr called his party the "Best Party." Because what could be better than the best party?

He created a 10-point campaign platform — with 13 points.
