Buying land on Mars sounds like a plot line in some futuristic sci-fi flick about billionaires. In truth, it's a modern-day possibility for thousandaires. Buy Planet Mars gives astrophiles the chance to buy one acre of land on the Red Planet. Much like the purchase of a star, Martian Land Packages include a map charting your acre's location, an owner's deed, a NASA report on Mars exploration, and a photo eBook. These packages are issued digitally, meaning they're available for download immediately after purchase.
