Former astronaut Gene Cernan has died, aged 82. He was the last man to walk on the moon.
Cernan was the commander in the Apollo 17 mission in December 1972, which was the last manned flight to the moon.
He spent three days there with astronaut Harrison Schmitt, collecting 249 pounds of lunar samples, before returning to the command module.
The astronaut recently released a book and appeared in a documentary about his experiences.
Before his mission to the moon in 1972, he had visited space twice - in 1966 and 1969.
His family said he passed away after ongoing health issues, and Nasa announced his death with a tweet.
The statement from the family said: "Gene was passionate about sharing his desire to see the continued human exploration of space and encouraged our nation's leaders and young people to not let him remain the last man to walk on the Moon."
