Of the 24 Nasa astronauts who travelled to the Moon in the Apollo missions of the 1960s and 1970s, just six remain.

Astronaut James Lovell, who was commander of the 1970 Apollo 13 mission that managed to get back to earth safely after an oxygen tank explosion, has died. He was 97.

He led the three-man crew that survived a near catastrophic explosion in space in 1970, and was later immortalized by Tom Hanks in the movie “Apollo 13.”
