Humans on Mars! Wouldn't that be amazing? Sooner or later we're going to run out of room on this "pale blue dot" we call home. Not only is it a necessity to expand to other worlds but reaching for the stars springs forward inventions that make our lives better and more efficient. Celebrate our next solar system mile-stone with a t-shirt supporting a few companies making this step possible. Tesla, Solar City, and SpaceX all will play a part in the eventual future of terraforming Mars.
