On this day 37 years ago, Eugene Cernan took a walk on the Moon. Since that day, no-one else has ever landed on the moon. In all, the moon has been visited by humans only six times. The first time, the one which everyone remembers, was on 16 July 1969, when Neil Armstrong and Buzz Aldrin landed in the lunar module on the Apollo 11 mission. Armstrong and Aldrin made some brief explorations on foot in the area around the landing site.
The second manned moon landing occurred just four months later, on 19-20 November 1969. Pete Conrad and Alan Bean of the Apollo 12 mission stayed on the moon for one day and seven hours. The next successful landing was with Apollo 14 on 5-6 February 1971, when Alan Shephard and Edgar Mitchell walked on the moon. Then came Apollo 15, when David Scott and James Irwin spent three days on the moon between 31 July and 3 August 1971. With Apollo 16, John Young and Charles Duke spent 3 days on the moon between 21 and 23 April 1972.
Finally, the last mission to the moon was Apollo 17. The mission was launched on 7 December 1972. Eugene Harrison and Harrison Schmitt were on the moon for three days from 11 to 14 December. The planned follow-up moon missions Apollo 198, 19 and 20 were cancelled due to budgetary constraints, and subsequent space exploration efforts have been diverted elsewhere.
