How NASA's space survival tactics saved 33 miners buried alive
In short: When 33 miners were trapped 2,300 feet underground in Chile, the government turned to an unlikely ally: NASA. Using expertise developed for the hostile vacuum of space, a team of experts helped manage the physical and psychological toll of a 69-day ordeal in total darkness.
Thirty-three individuals became stranded within a 98 percent humidity, 95°F heat zone after a portion of the San José Mine in Chile caved in on 5 August 2010. The Chilean government requested technical advice from NASA because of the agency's extensive experience protecting humans during long-duration missions in the hostile environment of space. NASA's contribution was a specialized component of a larger national rescue effort, involving a team of doctors, a psychologist, and an engineer who arrived in Santiago on August 31, 2010.
The NASA team, led by Dr. Michael Duncan of the Space Life Sciences Directorate, provided immediate recommendations on medical care, nutrition, and psychological support. Their role expanded to include engineering requirements for the design of the rescue capsule used to extract the miners. This collaboration lasted until the miners were brought to the surface 69 days after the collapse, appearing surprisingly healthy and mentally stable despite the extreme conditions.
A key psychological strategy employed was the "Triangle of Support." NASA psychologist Albert Holland worked with Chilean psychologist Alberto Iturra to manage the miners as an integrated system. They recognized that if surface managers failed to communicate effectively with the families, the families' transmitted anxiety would destroy the miners' morale. They held daily meetings with the family community to ensure that the rescue was treated as a marathon, not a sprint, preventing feelings of hopelessness and panic caused by prolonged sensory deprivation.
The miners' resilience was a point of study; experts were surprised by the men's social appropriateness and sense of time after nearly seven weeks of isolation. Because the miners had not been psychologically evaluated before their jobs, they were thrust into the crisis unprepared, making the application of operational psychology critical to their survival.
