Lunar Reconnaissance Orbiter Camera (LROC)

Lunar Reconnaissance Orbiter Camera (LROC) instruments. On the left is one of the two narrow angle cameras with a 88.9 mm (3.5 inch) Swiss Army Knife (and a hammer) for scale. On the right is the wide angle camera system, with the same pocket knife for scale.

The LROC investigation is led by Principal Investigator Mark Robinson of Arizona State University. Malin Space Science Systems designed and built the instruments. The LROC cameras, currently orbiting the Moon, are operated at Arizona State University in Tempe, Arizona, USA. 

LROC consists of two narrow angle cameras and a wide angle camera. The two narrow angle cameras provide extreme closeup images of the lunar surface with a spatial resolution of 0.5 meters (1.6 ft) per pixel over a swath that is 5 kilometers (3.1 mi) wide. 

The wide angle camera provides 100 meters (328 ft) per pixel images over a swath 100 kilometers (62 mi) wide. The wide angle system images the lunar surface at seven different wavelengths (310 - 680 nm) to characterize the distribution of lunar resources, particularly the iron-, titanium-, and oxygen-bearing mineral, ilmenite.
