Well, technically it's just my name that's going - on a microchip on a NASA laboratory lander. But it's quite cool all the same. And free, so I did it! I even get a lovely certificate too - although they do try to make it difficult to get a digital image to keep. However as I've sent my real name, here is a safely-edited-for-LJ one instead!
If you want to send yourself (or just your name)
go here.
