It's back, the next time Nasa flies to the red planet, you can have your name go too.
All you have to do is click here and fill in your name, address, postcode and email and you will then be given your boarding pass - just a shame we won't get to go too.
The mission is due to take place in July 2026 so there is quite a while before your name will head off into space.
You can download or print the boarding pass, which may not be a trip to mars but its pretty cool to have on your Instagram grid.
