In 2008, a team of researchers transformed a vacant fast-food restaurant near NASA's Ames Research Center into an unlikely archive laboratory, recovering lunar photographs from the 1960s that had been locked inside magnetic tapes no modern machine could read. The project, affectionately called McMoon's, reminds us that knowledge is not merely what we record, but whether we preserve the means to remember it. Across the gap of fifty years, human foresight — in the form of a researcher who kept both the tapes and the machines — made the difference between a living archive and a silent one.
McMoon's: How NASA Recovered Lunar Photos in a Former McDonald's
Keeping the medium was only half the battle. Without the machines, the information would remain inaccessible forever.
Mark
Why does it matter that they recovered these images? Weren't the original photographs already available?
Mimi
The original photographs that were printed in the 1960s were made from the same signals, but they lost information in the process. The magnetic tapes held the raw signal data—more complete. Modern processing could extract detail that had been there all along but wasn't visible in the printed versions.
Luke
But we should be clear: they weren't creating new detail. They were recovering information that had survived in the recording but was poorly represented before. That's an important distinction.
Mark
How did anyone even know these tapes still existed?
Mimi
A JPL researcher named Nancy Evans had preserved them. She understood that keeping the physical tapes wasn't enough—you also needed the machines to read them. So she kept the four tape drives as well.
Luke
And that's the real story. Most archives lose one or the other. Evans kept both. Without her decision decades earlier, this recovery wouldn't have been possible.
Mark
Why a McDonald's?
Mimi
The building was empty and available. It had space for the equipment and the team. Lynn Harper, a NASA employee, realized the old kitchen ventilation could help remove soldering fumes while they worked on restoring the drives.
Luke
It's practical, but it's also symbolic. The building's previous purpose didn't matter. What mattered was that someone recognized it could serve a new purpose.
Mark
Did they know the tapes would still work?
Mimi
No. That was the risk. They had to restore at least one of the four drives and prove the signals were still readable. The first successful recovery—an image of Earth above the lunar horizon—showed that the archive justified the effort.
Luke
And that's worth noting: they didn't know if this would work. They had to demonstrate proof of concept before committing to the full digitization project.
The Pulse
- Decades of irreplaceable lunar survey data sat effectively mute, physically intact but technologically stranded without the obsolete equipment needed to decode it.
- The clock was ticking on the machinery itself — four FR-900 tape drives, each weighing a thousand pounds, had to be painstakingly restored before any image could be recovered at all.
- A former McDonald's became the improbable staging ground for the effort, its old kitchen ventilation system repurposed to clear soldering fumes as engineers raced to resurrect Cold War-era hardware.
- On November 13, 2008, the first recovered image — an Earthrise over the Moon predating Apollo 8's famous photograph by more than two years — proved the archive held more detail than anyone had previously seen.
- By 2014, over 3,000 digitized lunar images had entered active scientific use, allowing researchers to compare 1960s lunar surfaces with modern observations and track changes across half a century.
In 2008, a team of researchers transformed a vacant fast-food restaurant near NASA's Ames Research Center into an unlikely archive laboratory, recovering lunar photographs from the 1960s that had been locked inside magnetic tapes no modern machine could read. The project, affectionately called McMoon's, reminds us that knowledge is not merely what we record, but whether we preserve the means to remember it. Across the gap of fifty years, human foresight — in the form of a researcher who kept both the tapes and the machines — made the difference between a living archive and a silent one.
In the summer of 2008, two trucks delivered 1,478 magnetic tapes and four massive 1960s-era tape drives to a recently vacated McDonald's restaurant near NASA's Ames Research Center in California. The building became the headquarters of the Lunar Orbiter Image Recovery Project — quickly nicknamed McMoon's — and the site of one of the most unusual acts of scientific archaeology in space history.
The tapes contained raw signal data from five Lunar Orbiter spacecraft that had scouted the Moon between 1966 and 1967, preparing the way for Apollo. The images had been printed at the time, but the original recordings — richer in detail — had sat in storage for decades, unreadable without compatible equipment. That equipment might have been lost entirely, had Nancy Evans of JPL not preserved both the tapes and the FR-900 drives capable of reading them. Her foresight proved decisive: the physical medium alone was not enough without the machines and knowledge to interpret it.
Project co-leader Dennis Wingo discovered Evans's archive through an online posting in 2007, and by July 2008 the tapes and drives were en route to Ames. The empty restaurant offered the one thing a conventional lab could not — enough space for the massive hardware. Even the old kitchen ventilation system found new purpose, clearing fumes as engineers worked to restore at least one of the four drives to working order.
The first public demonstration came on November 13, 2008: a restored image of Earth rising above the lunar horizon, taken by Lunar Orbiter 1 on August 23, 1966 — more than two years before Apollo 8's celebrated Earthrise. Crucially, the recovered version revealed far more detail than the prints made from it decades earlier. The signals had preserved information that earlier reproduction technology had failed to capture.
The project ran through 2014, ultimately digitizing 3,062 images from all five Lunar Orbiter missions and making them available through the Planetary Data System. Scientists could now use the archive as a baseline for comparing with modern lunar imagery, turning a historical curiosity into an active research tool. McMoon's endures as a lesson in what preservation truly requires: not just the medium, but the machines, the expertise, and the vision to bring them together before time runs out.
In the summer of 2008, two trucks pulled up to a former McDonald's restaurant near NASA's Ames Research Center in California. They were carrying 1,478 magnetic tapes and four hulking tape drives—machines from the 1960s, each weighing about a thousand pounds. The building, recently vacated by the fast-food chain, would become the unlikely headquarters for one of the most consequential acts of archaeological recovery in space history: the Lunar Orbiter Image Recovery Project, soon nicknamed McMoon's.
The tapes held something precious and nearly lost. Between 1966 and 1967, NASA had sent five Lunar Orbiter spacecraft to the Moon to scout landing sites for the Apollo missions. Each spacecraft carried a camera that exposed film, developed it in space, and scanned the images for transmission back to Earth. Engineers on the ground converted those transmitted signals into photographs. But the film never came home. What remained were the original recordings—the raw signal data captured on magnetic tape—and the photographs that had already been printed from them. For decades, those tapes sat in storage, their contents locked away by obsolescence. Without the machines that could read them, they might as well have been written in code.
The rescue began with an act of foresight. Nancy Evans, a researcher at the Jet Propulsion Laboratory, had preserved both the tapes and the four FR-900 tape drives that could potentially read them. She understood something fundamental: keeping the physical medium was only half the battle. Without compatible equipment and the technical knowledge to use it, the information would remain inaccessible forever. In 2007, Dennis Wingo, a project co-leader, learned of Evans's machines through an online posting. He contacted her and JPL. Keith Cowing helped secure initial funding. By July 2008, the archive and equipment were on their way to Ames.
The empty restaurant offered something a conventional laboratory could not: space. The building's previous life even provided a practical advantage. NASA employee Lynn Harper recognized that the old kitchen ventilation system could help remove soldering fumes as the team worked to restore the drives. The nickname McMoon's stuck because the work of recovering images from the Moon was literally happening where hamburgers had once been cooked.
The technical challenge was formidable. The project had to bridge two eras of technology: the analog tape drives from the 1960s and modern digital systems capable of processing the signals they produced. A contemporary computer could not simply replace the missing playback stage. The team had to make at least one of the four drives functional and prove that the archived signals still contained usable information. The goal was modest but testable: recover a single image and demonstrate that the archive was worth the effort.
On November 13, 2008, they succeeded. The first public demonstration showed a restored photograph of Earth rising above the lunar horizon, captured by Lunar Orbiter 1 on August 23, 1966—more than two years before Apollo 8's celebrated color Earthrise image. The restored view revealed something crucial: the signals preserved on the tapes contained more detail than the photographs that had been printed from them decades earlier. Modern digital processing could extract information that had survived in the recording but had been poorly represented in earlier reproductions. This was not invention. The camera's viewpoint and the features it had observed remained unchanged. But the recovery process showed that a familiar historical photograph could hold substantially more information than its widely circulated versions suggested.
The project continued. Between 2008 and 2014, the team digitized most of the original photographs from all five Lunar Orbiter missions—3,062 images in total. The enhanced material was made accessible through the Planetary Data System, transforming the archive from a historical curiosity into an active scientific resource. Researchers could now compare the recovered Lunar Orbiter views with images from the Lunar Reconnaissance Orbiter to study crater formation and other changes on the lunar surface. The work that began in a former McDonald's became part of a continuing scientific legacy.
McMoon's illustrates a durable problem in scientific preservation. Saving the physical medium is not enough if the machines that read it, the people who understand it, and the methods to process it all disappear. In this case, someone had preserved enough of all three. A researcher had kept the tapes and the drives. A project leader had the vision to find them. Engineers had the skill to restore the machinery. And an empty restaurant provided the space to do the work. The result was a bridge across fifty years—from the signals transmitted by spacecraft orbiting the Moon to a digital archive accessible to scientists today.
