Sign your name on Mars?

Ok maybe you cant literally take a ball point pen on the nearest space craft (you may in fact poke your eye out lol) but you can take all the credit for it! Thanks to couponproblog.net you can sign your name on a microchip carried by NASA'S Mars Science Lab rover to Mars in the year 2011! I am thinking this is a nifty things for the kiddos as you can even print them a certificate that says in 2011 there name will be on Mars! And its all for free...great for a science week theme!
