O'Reilly Solid Podcast (RIP) with Jon Bruner | Trip to McMoon's, pt 1 - the Lunar Orbiter Image Recovery Project

We’re kicking off our newest series, the O’Reilly Solid Podcast, with an episode recorded in the manager’s office of a McDonald’s at NASA’s Ames Research Center. David Cranor and I (Jon Bruner) visited McMoon’s, as it’s known, to talk with Dennis Wingo, founder of two audacious “techno archaeology” efforts. In the first episode, we discuss the Lunar Orbiter Image Recovery Project, which has rescued NASA’s first high-resolution images from satellites orbiting the moon. Dennis’ team reverse-engineered the extraordinary analog image transmission system that the satellites used in 1966 and 1967, digitized 14 tons of magnetic tape, and interpreted them to compose imagery at vastly higher resolution than NASA was originally able to recover from the satellites. Before the invention of the charge-coupled device (CCD), collecting and transmitting images was an electro-mechanical enterprise. The process required to get images from the moon to the earth highlights the ingenuity of NASA’s early engineers — and the relative ease of working with electronics today, when crossing between physical and virtual is straightforward.
