The First Lunar Observatory
| Title |
The First Lunar Observatory |
| Explanation |
The first, and so far only, lunar astronomical observatory [ http://snoopy.gsfc.nasa.gov/~lunartel/lunar1.html ] was deployed by the Apollo 16 [ http://antwrp.gsfc.nasa.gov/apod/ap960607.html ] crew in 1972. The Far Ultraviolet Camera / Spectrograph [ http://nssdc.gsfc.nasa.gov/nmc/tmp/1972-031C-10.html ] used a 3-inch diameter Schmidt telescope to photograph the Earth [ http://antwrp.gsfc.nasa.gov/apod/ap000701.html ], nebulae [ http://nineplanets.org/twn/ ], star clusters [ http://www.allthesky.com/clusters/clusters.html ], and the Large Magellanic Cloud [ http://antwrp.gsfc.nasa.gov/apod/ap000222.html ]. The tripod mounted astronomical equipment is seen above [ http://images.jsc.nasa.gov/images/pao/AS16/10075848.htm ], placed in the shadow of the Lunar Module [ http://www.nasm.edu/galleries/attm/nojs/ a11.am.lm.1.html ] (right) so it would not overheat. Also in the shadow is astronaut Charles Duke with the lunar rover [ http://antwrp.gsfc.nasa.gov/apod/ap990701.html ] in the background. The Far Ultraviolet Camera [ http://cass.jsc.nasa.gov/pub/expmoon/Apollo16/ A16_Experiments_UVC.html ] took pictures in ultraviolet light which would normally be blocked by the Earth's atmosphere. It was created by George Carruthers (NRL [ http://nrl.navy.mil/ ]), had a field of view of twenty degrees, and could detect stars having visual magnitude [ http://liftoff.msfc.nasa.gov/academy/universe/MAG.HTML ] brighter than eleven. One hundred seventy-eight images were recorded in a film cartridge which the astronauts returned to Earth. The observatory still stands on the Moon [ http://cass.jsc.nasa.gov/expmoon/lunar_missions.html ] today. |
