Wait -- Mars is made out of candy? Let's go! This Curiosity Rover built by Caltech has given us all the motivation we need:
Crafted by Kevin Isacsson, head chef of the Athaneum, the Pasadena university's private dining club, the rover features pinwheel cookie wheels connected with black licorice, sugared Lego "gears" and gumdrop and M&M "buttons." [...]
Caltech manages the Jet Propulsion Laboratory, which built the rover that is currently exploring the Red Planet. JPL lent Isacsson a model of Curiosity to help him craft the cake version, which took about 10 days. Isacsson has created a gingerbread structure each holiday season for the last eight years he's been at Caltech, but this was his first "scientific" mission.
