This Extra-vehicular visor assembly was worn by astronaut Neil Armstrong on the lunar surface during his historic Apollo 11 mission in July, 1969.
The A7-L Lunar Extravehicular Visor Assembly consists of a polycarbonate shell onto which the cover, visors, hinges, eyeshades, and latch are attached. It has two visors, one covered with a thermal control coating and the other with a gold optical coating. It also has two side sunshields which could be raised and lowered independently.
This helmet was worn over the pressure helmet and fastened with a latch during EVA periods, and provided impact, micrometeoroid, thermal, ultraviolet and infrared light protection.
Transferred to the National Air and Space Museum from NASA in 1971.
