Ionospheric Connection Explorer – Michelson Interferometer for Global High-Resolution Thermospheric Imaging

The MIGHTI instrument on the Ionospheric Connection Explorer (ICON) mission is designed to measure neutral winds and temperatures.

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 MIGHTI instrument include designing, fabricating, and testing two synchronized CCD camera systems, camera electronics, and the CCD TEC control electronics. SDL is also leading the payload integration and test (I&T) efforts for the mission, including the FUV and EUV instruments.
