The LADEE Ultraviolet-Visible Spectrometer (UVS) was successfully integrated to the LADEE SC on August 23, 2012. The UVS instrument will use its 3-inch limb viewing telescope and solar occultation viewer to search for atmospheric lunar dust and gasses, including sodium and potassium. In flight, UVS will use the limb-viewing telescope to scan from the surface of the moon to altitudes of 50 km to map the distribution of gasses and dust both spatially and in time. Periodically UVS will monitor the sun as it sets, using its solar occultation viewer, to search for dust very near the lunar surface. The UVS instrument is managed by NASA Ames Research Center with partners at Draper Laboratory and Goddard Space Flight Center. LADEE is schedule for launch in August, 2013
