Global-scale Observations of the Limb and Disk (GOLD)

Global-scale Observations of the Limb and Disk (GOLD) project has been selected to receive a $55 million grant from NASA’s Explorers program for flight as a mission of opportunity. The Principal Investigator, who will lead the mission, is Dr. Richard Eastes.

Sophisticated upper atmospheric models will be compared to GOLD data.

GOLD 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 address an overarching question in heliophysics science: What is the global-scale response of the thermosphere and ionosphere to forcing in the integrated Sun-Earth system?

Measurements from GOLD will be used, in conjunction with sophisticated models of the terrestrial thermosphere and ionosphere, to revolutionize our understanding of the space environment.
