Keystone Program
ESA Earth Explorer 12 assessment candidate selected in April 2024, Keystone would study the whole-atmosphere chemistry-climate system from roughly 50 to 250 km with a limb-sounding instrument spanning terahertz, infrared and UV-visible wavelengths, measuring atomic oxygen, trace gases, temperature and wind. It remains an assessment candidate pending later down-selection for implementation.
