NASA's Orion capsule is orbiting the moon this week, preparing for the return of crewed missions to the lunar surface. 50 years ago, on December 7, 1972, Apollo 17 launched, the last mission with astronauts to the Moon.
On December 7, 1972, Apollo 17 launched from NASA's Kennedy Space Center. On board were astronauts Eugene Cernan, Harrison Schmitt and Ron Evans.
Astronauts Cernan and Schmitt spent three days on the lunar surface, the longest lunar stay of the Apollo program, while astronaut Evans remained in lunar orbit.
On December 11, 1972, astronaut Cernan steered the Challenger lander toward a lunar valley called Taurus-Littrow. At his side was geologist Harrison "Jack" Schmitt.
They spent more than three days on the Moon, including over 22 hours outside the lander, and collected about 113 kg of samples.
On December 14, 1972, astronaut Cernan became the last of about 12 people to walk on the surface of the Moon.
Only Harrison Schmitt is still alive.
Ron Evans died in April 1990. Gene Cernan died in January 2017.
NASA's Orion capsule, with the dummy aboard, circled the moon again on December 5, passing over several of the landing sites of the Apollo missions before beginning its return to Earth.
The Orion capsule will land in the Pacific off the coast of San Diego, setting the stage for a future astronaut flight.
NASA considers this a general test for the trip with astronauts to the Moon that is expected to be realized by 2024.
A descent of astronauts to the surface of the Moon could be realized in 2025.
Astronauts last visited the Moon 50 years ago during the Apollo 17 mission.
