NASA’s Earth-observing satellite missions track dozens of features of a changing planet — aerosols, sea levels, land cover, cloud cover — over years and decades. Sustaining that record for the scientific and operational communities who depend on it requires more than engineering talent. It requires planning for an uncertain future: anticipating where a mission [...]
