Global-scale Observations of the Limb and Disk
From Wikipedia, the free encyclopedia
Global-scale Observations of the Limb and Disk (GOLD) is a heliophysics Mission of Opportunity (MOU) for NASA's Explorers program.[6] Led by Richard Eastes at the Laboratory for Atmospheric and Space Physics, which is located at the University of Colorado Boulder, GOLD's mission is to image the boundary between Earth and space in order to answer questions about the effects of solar and atmospheric variability of Earth's space weather.[7] GOLD was one of 11 proposals selected, of the 42 submitted, for further study in September 2011.[8] On 12 April 2013, NASA announced that GOLD, along with the Ionospheric Connection Explorer (ICON), had been selected for flight in 2017.[6] GOLD, along with its commercial host satellite SES-14, launched on 25 January 2018.[9]
