(CNN) -- Sitting incongruously among the hangars and laboratories of NASA's Ames Research Center in Silicon Valley is the squat facade of an old McDonald's. You won't get a burger there, though -- its cash registers and soft-serve machines have given way to old tape drives and modern computers run by a rogue team of hacker engineers who've rechristened the place McMoon's. These self-described techno-archaeologists have been on a mission to recover and digitize forgotten photos taken in the '60s by a quintet of scuttled lunar satellites.

The Lunar Orbiter Image Recovery Project (LOIRP) has since 2007 brought some 2,000 pictures back from 1,500 analog data tapes. They contain the first high-resolution photographs ever taken from behind the lunar horizon, including the first photo of an earthrise (first slide above). Thanks to the technical savvy and DIY engineering of the team at LOIRP, it's being seen at a higher resolution than was ever previously possible.
"We're reaching back to a capability that existed but couldn't be touched back when it was created," says Keith Cowing, co-lead and founding member at LOIRP. "It's like having a DVD in 1966, you can't play it. We had resolution of the Earth of about a kilometer [per pixel]. This is an image taken a quarter of a f***king million miles away in 1966. The Beatles were warming up to play Shea Stadium at the moment it was being taken."
Between 1966 and '67, five Lunar Orbiters snapped pictures onto 70mm film from about 30 miles above the moon. The satellites were sent mainly to scout potential landing sites for manned moon missions. Each satellite would point its dual lens Kodak camera at a target, snap a picture, then develop the photograph. High- and low-resolution photos were then scanned into strips called framelets using something akin to an old fax machine reader.
The images were beamed in modulated signals to one of three receiving stations in Australia, Spain, or California, where the pictures--and collateral chatter from the NASA operators--were recorded straight to tape. After finishing their missions, the satellites were unceremoniously dashed against the moon rocks, clearing the way for Apollo. The brilliant and ballsy engineering was typical of NASA during its golden age, a time when it was also more closely linked to other government agencies with an interest in taking pictures from space.
"These guys were operating right at the edge," Cowing says with a reverence for these NASA engineers that's shared by his team. "There's a certain spy program heritage to all this, but these guys went above that, because those spy satellites would send their images back. These didn't. They couldn't. They were in lunar orbit."
