Global-scale Observations of the Limb and Disk

Global-scale Observations of the Limb and Disk (GOLD) is a NASA mission of opportunity that will fly an ultraviolet (UV) imaging spectrograph on a geostationary satellite to measure densities and temperatures in Earth’s thermosphere and ionosphere.

The goal of the investigation is to provide answers to key elements of an overarching question for Heliophysics science: What is the global-scale response of the thermosphere and ionosphere to forcing in the integrated Sun-Earth system?

The measurements from GOLD will be used, in conjunction with advanced models of the thermosphere and ionosphere, to revolutionize our understanding of the space environment.
