Short answers, pulled from the story.
Edgar Mitchell served as Lunar Module Pilot on Apollo 14, landing on the 5th of February 1971 in the Fra Mauro Highlands. He spent nine hours working on the lunar surface alongside Commander Alan Shepard, collected nearly one hundred pounds of lunar samples, and deployed scientific equipment. He logged a total of 216 hours and 42 minutes in space during the mission.
On the return journey from Apollo 14, Mitchell experienced what he described as a savikalpa samadhi, a state of profound altered awareness. He said the experience gave him an instant global consciousness and an intense dissatisfaction with the state of world politics. He also conducted private ESP experiments during the mission, the results of which were published in the Journal of Parapsychology in 1971.
Mitchell founded the Institute of Noetic Sciences in Palo Alto, California in 1973, following his Apollo 14 mission. It was created for the purpose of consciousness research and related phenomena. Mitchell described its mission as reconciling the scientific and spiritual faces of reality, which he believed had been artificially separated for centuries.
Mitchell publicly stated he was ninety percent sure that many UFOs recorded since the 1940s were visitors from other planets. He told Dateline NBC in 1996 that officials from three countries had described personal encounters with extraterrestrials, and he claimed governments were covering up evidence of alien contact. In a 2014 interview, he acknowledged that his statements about a global UFO cover-up were speculation.
Mitchell was part of the Apollo 13 Mission Operations Team on the ground. His specific task was working out how to control the attitude of the Lunar Module with a damaged Command and Service Module attached, reversing the normal configuration. President Nixon awarded the team the Presidential Medal of Freedom in 1970 for their work bringing the crew home safely.
In 2011, the federal government sued Mitchell after learning he had placed an Apollo 14 camera up for auction at Bonhams. Mitchell maintained NASA had given him the camera as a gift after the mission. The parties settled in October 2011, with Mitchell returning the camera for display at the National Air and Space Museum. Congress followed in 2012 by enacting H.R. 4158, confirming astronauts' ownership rights over their mission artifacts.
