Elon Musk and Jeff Bezos have already put in bids, but don't be discouraged. You can still put in an offer for NASA's Mobile Launcher Platforms that helped shoot off Apollo missions, too. The three 4,115-ton space shuttle platforms are currently on the market, however the transporters that previously moved the platforms before are not included.
Time to find some engineers who reaaaallly like puzzles. These will have to be completely broken down and moved like that. Oh, by the way, they weigh 8,230,000 pounds. They also don't have any of the necessary equipment for launching. So, who's ready to fill out the application!?
