Munin is a Swedish nanosatellite. It was launched on November 21, 2000 on a Delta II rocket from the Vandenberg Air Force Base in California, together with two other satellites. Munin was developed by the Swedish Institute of Space Physics in cooperation with students from Luleå University of Technology and Umeå University. Last contact was on December 2nd, 2001, after a manual CPU reset. The failure of the satellite was likely in the boot PROM.
