Dennis Wingo, co-lead of the Lunar Orbiter Image Recovery Project, is shown at work in the project's "McMoon" laboratory in this undated photograph.
The project works from a former McDonald's restaurant because of its ready access to sinks, ventilation, and air-conditioning, Wingo said.
The Lunar Orbiter tapes being restored on the tape drives seen above spent many years in climate-controlled storage at the Jet Propulsion Laboratory in California. But the four drives used by the project are among the last of their type, and they spent 30-odd years in Planetary Data System co-founder Nancy Evans' garage.
Extensive refurbishment was required to make the drives work again, including using liquid nitrogen to separate metal parts.
Many of the other tape drives like these now serve as artificial reefs in the ocean.
