Imaging the boundary between Earth and space
The Global-scale Observations of the Limb and Disk (GOLD) mission is a NASA Mission of Opportunity that fills a critical gap in our knowledge of Sun-Earth connections. It is examining the response of the upper atmosphere to forcing from the Sun, the magnetosphere, and the lower atmosphere. GOLD provides unprecedented imaging of Earth’s upper atmosphere from geostationary orbit to study the weather of the thermosphere-ionosphere. It has made breakthrough measurements of temperature and composition that are important for satellite drag and ionospheric disruptions of communication and navigation.
