Query: Twelve Years of Education and Public Outreach with the Fermi Gamma-ray
  Space Telescope   During the past twelve years, NASA's Fermi Gamma-ray Space Telescope has
supported a wide range of Education and Public Outreach (E/PO) activities,
targeting K-14 students and the general public. The purpose of the Fermi E/PO
program is to increase student and public understanding of the science of the
high-energy Universe, through inspiring, engaging and educational activities
linked to the mission's science objectives. The E/PO program has additional
more general goals, including increasing the diversity of students in the
Science, Technology, Engineering and Mathematics (STEM) pipeline, and
increasing public awareness and understanding of Fermi science and technology.
Fermi's multi-faceted E/PO program includes elements in each major outcome
category: Higher Education; Elementary and Secondary Education; Informal
Education and Public Outreach.
