Lunar Module 2 (LM-2)

Lunar Module 2 (LM-2) was the second production lunar module produced by Grumman. As an early vehicle, its configuration was changed around a bit, being alternately capable of being able to fly manned or unmanned; at one point, there were actually talks of having LM-2 launched and perform one burn unmanned, but then be manned for "additional activities."

However, the flight of LM-1 on AS-204 in January 1968 made all of this moot, as this first unmanned test flight of the lunar module was successful enough that it was decided to relegate LM-2 to a ground-testing regimen and fly LM-3 on Apollo 9.

Shortly after the Apollo 11 landing, LM-2 was transferred to the Smithsonian, who loaned its ascent stage to the "Expo '70" in Japan for several months, before eventually putting it on display.

Today LM-2 sits in an unfortunately high-traffic area of the Smithsonian, as it is in the hallway leading from the museum to the McDonald's restaurant attached to the museum.
