Exploring Where Earth's Weather Meets Space Weather

The Ionospheric Connection Explorer (ICON), the newest addition to NASA’s fleet of Heliophysics satellites, launched on October 10, 2019 at 9:59 p.m. EDT. Led by UC Berkeley, scientists and engineers around the world came together to make ICON a reality.

The goal of the ICON mission is to understand the tug-of-war between Earth’s atmosphere and the space environment. In the "no mans land" of the ionosphere, a continuous struggle between solar forcing and Earth’s weather systems drive extreme and unpredicted variability. ICON will investigate the forces at play in the near-space environment, leading the way in understanding disturbances that can lead to severe interference with communications and GPS signals.

The MIGHTI Engineering Unit optics integration and vibration test is complete

ICON’s Michelson Interferometer for Global High-resolution Thermospheric Imaging (MIGHTI) instrument includes two identical optical assemblies, one for each of the perpendicular fields of view that will observe thermospheric wind-vector and temperature profiles. An engineering unit of the optical assembly was completed and successfully vibration tested in June 2015 at the Naval Research Laboratory.
