摘要:The Colorado Student Space Weather Experiment (CSSWE: http://lasp.colorado.edu/home/csswe/) is a three- unit (10cm?10cm?30cm) CubeSat mission funded by the National Science Foundation, launched into a low-altitude, high-inclination orbit on 13 September 2012 as a secondary payloadunderNASA’sEducationalLaunchofNanosatellites (ELaNa) program. The ground station at the University of Colorado at Boulder (also designed and built by students) was able to find, track, and receive beacon packets during the CubeSat’s first pass over Boulder. On 4 October 2012, the commissioning phase was completed and the science instrument,whichmeasuresenergeticelectronsandprotons, was turned on.
