SPACE.com: Last week, Chilean officials called on NASA to help with the group of 33 miners trapped underground in a gold and copper mine since 5 August. This week, NASA is sending two physicians, one psychologist, and one engineer to Chile to provide nutritional and psychological support to the miners. Because the rescue mission could take up to four months, officials had called on NASA because of its “long experience in dealing with isolated environments"—including the International Space Station as well as undersea environments and Antarctica—according to NASA’s deputy chief medical officer Michael Duncan, of the Johnson Space Center in Houston.
