Now you can. NASA now gives anyone the opportunity to send their name to Mars. Just enter your name, country and zip code into the form, and your name – along with many others – will be included in a microchip on the Mars Science Laboratory rover which will be heading to Mars in 2011. I just did and this is the “Certificate of Participation”.
But there is one problem. There is no data validation of the form. First of all, there’s no captcha, and the form accepts nearly anything, even very long entries. Check out some cool examples here and here, and hurry up if you really want your name to be on Mars because I suspect that the form might stop accepting new entries soon.
