This Game Boy and its obligatory Tetris cartridge were taken aboard the Mir space station by cosmonaut Aleksandr A. Serebrov in 1993. It stayed in space for nearly 200 days, and was no doubt responsible for many lost hours of productivity. Now, it can be yours, along with a bunch of other cool stuff that's being auctioned off in New York on Thursday.
Below we've got a gallery of some of the most interesting lots from the 250 item auction, but if you're a space history buff, the entire gallery is worth a browse. And don't worry if you can't make it to New York: most items, including the Game Boy, can be bid on online.
