Global-scale Observations of the Limb and Disk

The Global-scale Observations of the Limb and Disk (GOLD) mission of opportunity 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.

 
UPDATES:
Apr 2013 - GOLD has been selected by NASA to be the next Heliophysics Explorer mission of opportunity. GOLD was selected along with a Heliophysics Explorer satellite mission (ICON: Ionospheric Connection Explorer) to proceed into development.
