US astronaut Edgar Mitchell, who had been the sixth man to walk on the Moon, has died aged 85.
Captain Mitchell passed away in a hospice in West Palm Beach, Florida, one day before the 45th anniversary of his Moon landing, his family said.
He explained he’d undergone an epiphany in life revealed a belief that aliens had visited Earth and in space.
Mr Mitchell’s mission to the Moon was the fourth in the US Apollo string, and also the first to follow the ill-fated Apollo 13 which aborted its attempt to land after an oxygen tank explosion.
Mr Mitchell and his crewmate, Captain Alan Shepard, another Navy officer, made it to the lunar surface. Their landing site was a hilly place that was the objective of the failed Apollo 13 mission, the Fra Mauro Highlands.
During their 33 hours at the site, the two astronauts gathered 45kg (94lb) of Moonrock for evaluation back on world and finished the longest moonwalk in history.
