Virgin wants you to pay for your next Virgin Galactic flight into space with a futuristic, virtual currency known as Bitcoin.

Bitcoin was worth less than than $10 just two years ago, and now its value has reached $900. A US Senate committee hearing even dubbed it a legitimate financial service, piquing Sir Richard Branson's interest.

In fact, the founder of Virgin Group is so interested that he's invested in bitcoins. He's also announced that Virgin Galactic customers can choose to pay with Bitcoin, starting immediately.

"Virgin Galactic is a company looking into the future, so is Bitcoin. So it makes sense we would offer Bitcoin as a way to pay for your journey to space," wrote Branson in a blog post on Virgin's website.

Branson noted one "future astronaut" from Hawaii had already bought a Virgin Galactic ticket using bitcoins, and he expects many more will follow, though he neglected to mention how much it will cost.
