Washington D.C. - National Air and Space Museum - Eugene Cernan A7-L Pressure Lunar Suit

This spacesuit was constructed for and worn by astronaut Eugene Cernan,

Lunar Module pilot of the Apollo 17 mission in 1972.


Apollo 17 was the eleventh and final manned mission in the United States Apollo space program. Launched at 12:33 a.m. EST on 7 December 1972, with a three-member crew consisting of Commander Eugene Cernan, Command Module Pilot Ronald Evans, and Lunar Module Pilot Harrison Schmitt, Apollo 17 remains the most recent manned Moon landing and the most recent manned flight beyond low Earth orbit.


Apollo 17 was the sixth Apollo lunar landing, the first night launch of a U.S. human spaceflight

and the final manned launch of a Saturn V rocket. It was a "J-type mission",

missions including three-day lunar surface stays, extended scientific capability,

and the third Lunar Roving Vehicle. While Evans remained in lunar orbit above in the Command/Service Module, Cernan and Schmitt spent just over three days on the lunar surface in the Taurus-Littrow valley, conducting three periods of extra-vehicular activity, or moonwalks, during which they collected lunar samples and deployed scientific instruments. Cernan, Evans,

and Schmitt returned to Earth on 19 December after an approximately 12-day mission.


The decision to land in the Taurus-Littrow valley was made with the primary objectives for Apollo 17 in mind: to sample lunar highland material older than the impact that formed Mare Imbrium and investigating the possibility of relatively young volcanic activity in the same vicinity. Taurus-Littrow was selected with the prospects of finding highland material in the valley's north and south walls and the possibility that several craters in the valley surrounded by dark material could be linked to volcanic activity.


Apollo 17 also broke several records set by previous flights, including the longest manned lunar landing flight; the longest total lunar surface extravehicular activities; the largest lunar sample return, and the longest time in lunar orbit.


This spacesuit has the designation A7-L and was constructed in the EV (extra-vehicular) configuration.


It permitted maximum mobility and was designed to be worn with relative comfort for up to 115 hours in conjunction with the liquid cooling garment. It was also capable of being worn for 14 days in an unpressurized mode.


The spacesuit was made by the International Latex Corporation, and transferred to the

National Air and Space Museum from NASA - Manned Spacecraft Center in 1973.
