OMM activities are being developed around four main objectives:

  • instrument design for national, international and space observatories  through its Laboratory for Experimental Astrophysics (LAE),
  • formation of highly-qualified personnel,
  • dissemination of astrophysical knowledge through a vigorous outreach program.
