What is SNOE?

SNOE-BadgeSNOE (“snowy”) was a small scientific satellite that measured the effects of energy from the sun and from the magnetosphere on the density of nitric oxide in the Earth’s upper atmosphere. The spacecraft and its instruments were designed and built at LASP, the Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder. SNOE was launched on February 26, 1998, and was operated from the mission operations center at the LASP Space Technology Research building. SNOE re-entered the Earth’s atmosphere on Dec. 13, 2003, completing a very successful mission. This site contains a description of the SNOE mission, spacecraft drawings and images, and provides access to the scientific data and publications.


SNOE data from March 11, 1998 through September 30, 2000 are available on this website.
