Ionospheric Connection Explorer – Far Ultraviolet Imaging Spectrograph

The FUV instrument on the Ionospheric Connection Explorer (ICON) mission is designed to measure daytime thermospheric and nighttime ionospheric density profiles. The purpose of NASA’s Ionospheric Connection Explorer (ICON) mission is to explore how both terrestrial and space weather affect conditions in the ionosphere, the region of plasma forming the boundary between Earth and space. The ionosphere is energetically coupled to the thermosphere through collisions between ions, electrons, and neutral gas. These interactions often show extreme temporal and spatial variability, which can be very disruptive to global positioning satellites (GPS) and radio communications.

SDL’s contributions to the FUV instrument included designing, fabricating, and testing two CCD camera systems, camera electronics, and the electronics for turret control. SDL is also leading the payload integration and test (I&T) efforts for the mission, including the MIGHTI and EUV instruments.

SDL is part of the UC Berkeley-led team, who released the following video about the ICON mission.
