  Space and Planetary Exploration Laboratory (SPEL) was built in 2011 in the Electrical Engineering Department of the 
  University of Chile to serve as the headquarters of the design, construction, development, and operation of the first
  Chilean nanosatellite, SUCHAI. Since that year, many students have contributed to the SUCHAI project and others, extending 
  the research areas of the laboratory.
