US Astronaut Edgar Mitchell, who was the sixth man to walk on the Moon, has died at the age of 85. He passed away at a hospice in West Palm Beach, Florida. As part of the Apollo 14 mission in 1971, he spent more than nine hours on the Moon’s surface. He said he had had an epiphany in space and later devoted his life to studying the mind and unexplained phenomena. He said he believed that aliens had visited Earth.

Mitchell left the US space agency Nasa in 1972 and set up the Institute of Noetic Sciences, which aimed to support individual and collective transformation through consciousness research.
