Task 2 of the ultraviolet spectrometer experiment S169

The far ultraviolet spectrometer for the Apollo 17 lunar scientific mission was constructed to meet the specific requirements and technical specifications as directed by the National Aeronautics and Space Administration. The Ebert Scanning Monochromator (UVS) was derived from extensive experience in the development of a variety of Ebert scanning monochromators for experiments aboard rockets and satellites. This equipment has the capability to make quantitative measurements of the composition of the lunar atmosphere as seen from the Apollo 17 CSM in lunar orbit, and to study the spectra of a number of astronomical sources during trans-earth coast.
