Flight Data Systems and Radiation Effects Branch, Code 561

The Flight Data Systems and Radiation Effects Branch supports both Space and Earth science:
  • For Space Science we help to explore the solar system, search for life beyond Earth and assist in solving the mysteries of the universe.
  • For Earth Science we help to detect long term climate changes, its causes and impacts.
