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


Global-scale Observations of the Limb and Disk (GOLD) is a NASA heliophysics mission that will examine the response of the upper atmosphere to forcing from the Sun, the magnetosphere, and the lower atmosphere.

GOLD will perform a two-year mission, imaging the Earth's thermosphere and ionosphere from geostationary orbit. The mission provides new capabilities for imaging the boundary between Earth and space in order to answer key questions about the effects of solar and atmospheric variability on the Earth's space weather.The GOLD instrument is a two-channel Far Ultraviolet (FUV) imaging spectrograph.

Launch: January 2018
