Far-Ultraviolet Camera/Spectroscope

NSSDCA ID: 1972-031C-10

Mission Name: Apollo 16 Lunar Module /ALSEP
Principal Investigator:Dr. George R. Carruthers


This experiment constituted the first planetary-based astronomy observatory and consisted of a tripod-mounted, 3-in electronographic Schmidt camera with a cesium iodide cathode and film cartridge. Spectroscopic data were provided in the 300- to 1350-A range (30-A resolution), and imagery data were provided in two passbands (1050 to 1260 A and 1200 to 1550 A). Difference techniques allowed Lyman-alpha (1216-A) radiation to be identified. The astronauts deployed the camera in the shadow of the LM and then pointed it toward objects of interest. Specific planned targets were the geocorona, the earth's atmosphere, the solar wind, various nebulae, the Milky Way, galactic clusters and other galactic objects, intergalactic hydrogen, solar bow cloud, the lunar atmosphere, and lunar volcanic gases (if any). At the end of the mission, the film was removed from the camera and returned to earth.
