Gene Cernan, the last astronaut to walk on the moon - an experience that he said made him “belong to the universe”, died on Monday at the age of 82, the US space agency said.
Cernan died surrounded by his family, the National Aeronautics and Space Administration said in a statement without providing details.
A separate statement from his family and released by Nasa said his death came after “ongoing health issues”.
Here are a few facts about him:
• Spacewalk from hell
In addition to being one of 12 men to walk on the moon, Cernan was the third person to walk in space, following Russian Alexei Leonov and American Ed White.
Cernan spent two hours and seven minutes outside the Gemini 9 spacecraft on the 1966 mission but had to come in early because his helmet visor was fogging up due to exertion. Because the spacewalk was shortened, Cernan did not have a chance to test a new jetpack. He recalled the incident in his memoir in a chapter titled “The Spacewalk From Hell.”
• Fastest man on moon
Cernan holds the moon’s speed record, having driven the lunar rover at 11.2 miles per hour (18km per hour) on a downhill run.
• Almost missing the moon
He almost missed out on Apollo 17 because he severely strained a tendon in his leg playing softball with Nasa personnel two months before the launch. He used crutches for a week and willed himself not to limp so Nasa officials would not pull him from the mission but said walking on the moon was painful.
• Security threat
Security at Cape Kennedy had to be increased for Apollo 17 because of the threat of attack from Black September, the Palestinian group that had killed 11 Israelis at the Summer Olympics in Munich three months earlier. Officials also were concerned about the astronauts’ families, so authorities followed their children’s school buses and federal agents kept an eye on their classrooms.
• Nasa reprimand
Less than two weeks after returning from the moon, Cernan and crew mate Ron Evans went to Bimini in the Bahamas for New Year’s as the guests of the chief executive of Rockwell International. Cernan said the executive was an old friend but there were conflict of interest concerns in Washington because Rockwell manufactured modules for Nasa spacecraft. Cernan was given a letter of reprimand from the agency.
• Third meets first
Cernan met Neil Armstrong, the first man to walk on the moon, at Purdue University, where they studied in the 1950s.
