Global-scale Observations of the Limb and Disk (GOLD) mission
Global-scale Observations of the Limb and Disk (GOLD) mission, launched by NASA, studies the EarthÂ’s upper atmosphere, which hosts astronauts, radio signals used for guiding airplanes and ships as well as satellites that provides communications and GPS systems. Its objective is to understand the basic physics of nearest space in order to help protect the space assets.
Data from GOLD mission revealed an unexpected behavior in the swaths of ions that band EarthÂ’s equator. The finding was made because, since the GOLD is located in geostationary orbit, it can capture the changes in the same area for a long time across longitude and latitude.
