Of all the alternative and privately funded spaceflight experiments to crop up in recent years, Mars One has arguably been among the most visible. Which is, of course, exactly what Bas Lansdorp wanted. After all, the Dutch entrepreneur modeled his endeavor, a mission to send regular folks to Mars, after the reality TV show Big Brother, going so far as to meet with the series' producer for guidance. “We’re talking about creating a major media spectacle,” Lansdorp told the New York Times near the project’s launch a little over a year ago. “Much bigger than the moon landing or the Olympics.”

But despite Mars One’s unconventional business plan — which involves funding the colonization effort through crowdfunding, corporate sponsorship, and what it hopes will be massive ad revenues — Lansdorp’s group isn’t exactly rewriting the playbook. Spats with NASA notwithstanding, the Mars One website still borrows the agency’s most famous slogan: “The next giant leap,” it reads, “starts right here on Earth.”

Which comes as no surprise to David Meerman Scott and Richard Jurek. The two marketing professionals — who have been collecting moon memorabilia for two decades — recently compiled over 200 advertisements, TV stills, and photographs from their private collections to illustrate the massive effort required to garner public support for the Apollo program.
