[tech] The Hackers Who Recovered NASA’s Lost Lunar Photos … a wonderful story of digital archeology …
The photos were stored with remarkably high fidelity on the tapes, but at the time had to be copied from projection screens onto paper, sometimes at sizes so large that warehouses and even old churches were rented out to hang them up. The results were pretty grainy, but clear enough to identify landing sites and potential hazards. After the low-fi printing, the tapes were shoved into boxes and forgotten.
They changed hands several times over the years, almost getting tossed out before landing in storage in Moorpark, California. Several abortive attempts were made to recover data from the tapes, which were well kept, but it wasn’t until 2005 that NASA engineer Keith Cowing and space entrepreneur Dennis Wingo were able to bring the materials and the technical know how together.
When they learned through a Usenet group that former NASA employee Nancy Evans might have both the tapes and the super-rare Ampex FR-900 drives needed to read them, they jumped into action.
