Image: a portion of our set of Lunar Orbiter data tapes at McMoon's - an abandoned McDonalds onsite at NASA Ames Research Park, home of the LOIRP - Lunar Orbiter Image recovery Project.
Here at the LOIRP (Lunar Orbiter Image Recovery Process) project there are two different phases of the image retrieval process that are distinct from each other. The second phase, the production of the vast majority of all the of the Lunar Orbiter images, will simply involve putting tapes on the tape drive machines, acquiring the data, and processing them into images.
However, we're still in the first phase of the project where we need to search through tapes in a painstaking fashion just to find the images we are interested in downloading. Once we find what we are looking for, downloading is a snap and can be done in a matter of hours.
Finding the images using a jumbled nomenclature and labeling system last used more than 40 years ago is part of what we call "Technoarchaeology".
