Apollo 17’s lunar module was named Challenger.
Challenger carried Eugene Cernan and Harrison Schmitt from lunar orbit to the Taurus–Littrow valley on December 11, 1972. After landing, the astronauts used the module as their living and working base during three lunar surface excursions. It later lifted off from the Moon and rendezvoused with Ronald Evans in the command module America.
The name Challenger was also used decades later for the Space Shuttle Challenger, which first flew in 1983. The two spacecraft were unrelated, although both names referred to a vehicle undertaking a demanding exploration mission.
Apollo spacecraft names can be easy to mix up. Eagle belonged to Apollo 11, Antares to Apollo 14, Falcon to Apollo 15, and Orion to Apollo 16. Challenger was the final Apollo lunar module to land on the Moon, making it an especially important name in the program’s history.
