The Narrow Angle Camera (NAC) from the Lunar Reconnaissance Orbiter (LRO) is a CCD camera attached to a powerful telescope with a 700mm focal length. It can take black and white images of the Moon with a resolution of less than a meter.
This flight spare instrument is identical to the flown instrument built by Malin Space Science Systems. NASA transferred the camera to the Museum in 2016.
This object is on display in Kenneth C. Griffin Exploring the Planets Gallery at the National Air and Space Museum in Washington, DC.
