Here's a fact that will make you crap your pants:
Sir Richard Branson says they've now accepted deposits for suborbital flights on SpaceShipTwo from 529 future astronauts — which is more than the total count of people who have been to space throughout human history.
You can clean out your pants now, we'll wait!
The first flight will be taking place next year (unless the world ends in December), and Branson's two kids will be on the first flight!
Plus, at 68 miles above the Earth, they'll be experiencing a few minutes of weightlessness, which has to be the coolest thing ever.
They should put them all on the same flight, and then everyone should make Apollo 13 jokes at Tom Hanks.
