Good news for anyone who's stared in envy as NASA sends rover after rover to explore and study Mars. You no longer need countless millions and a team of rocket scientists to perform your own experiments on the red planet. For just $25 ThinkGeek will sell you your very own shard of our celestial neighbor.

Examined and authenticated by scientists, Martian shergottite NWA 4930 landed in northwest Africa and was confirmed to be a chunk of Mars that was presumably launched into space—and onto Earth—after a meteor crashed into the planet. For $25 your piece of Mars is only about two milligrams in size, but it comes tastefully displayed in a protective shell that includes a magnet for hanging. And remember, given the rovers on Mars never return home, it's not like NASA's going to have access to a sweet souvenir like this. [ThinkGeek]
