Is there life on Mars? Yes, there is—in Kurt Vonnegut’s science fiction novel *The Sirens of Titan*, the reader can visit not only Mars but also Mercury and Titan alongside the protagonist: Malachi Constant, a wealthy American playboy. On Mars, Malachi is transformed into ‘Uncle,’ loses his memory and everything he owns, and is forced to obey the orders of those who have implanted a chip in his brain—a device that inflicts excruciating pain whenever he refuses to comply with his superiors' commands.
