The Secret 1969 NASA Mission That Sent Six Men Into the Deep Ocean
In short: In July 1969, NASA launched a little-known experiment involving six men sealed inside a tiny capsule. This documentary explores their 30-day mission to survive and explore the Gulf Stream, featuring the recovery of the PX-15 submarine and interviews with the surviving crew.
While NASA conducted deep-sea research, the U.S. Navy simultaneously ran the Sealab program between 1964 and 1969. This initiative tested whether humans could live and work at depths of up to 180 metres, or 600 feet, using underwater habitats. These aquanauts endured extreme pressures to perform tasks on the ocean floor.
The Navy's Sealab program concluded in 1969 following a fatal accident where a diver died from carbon monoxide asphyxiation while attempting to fix a leaking helium tank. The PX-15 mission, led by marine archaeologist James Delgado, highlights the era's intense focus on human endurance in extreme, uncharted environments.
