Do you dream of living on Mars? Then turn on your webcam. You've got an application video to make.

Mars One, a Netherlands-based group that wants to turn the colonizing of Mars into a reality television phenomenon, has started accepting applications for its astronaut selection program.

In just two weeks, more than 78,000 people from more than 120 countries have applied.

You don't need previous experience in rocket science, astronomy, or really anything to apply for the Mars One astronaut selection program -- but you will need to be at least 18 years old and have nerves of steel.
