In March 2016, NASA plans to launch a mission from Vandenberg AFB to put the geophysical lander, InSight on Mars. You can submit your name for inclusion on a microchip that will be fixed on the structure of the lander.

And you even get a unique Boarding Pass, and Frequent Flyer Miles!
Last day for registration is September 8th 2015. My astronomy club is sharing this with school groups.
