Committee on Earth Observing Satellites
The Committee on Earth Observation Satellites (CEOS) is an international organization charged
with coordinating international civil space-borne missions designed to observe and study planet
Earth. Current membership is composed of 41 space agencies and other national and international
organizations. It was created (1984) in response to a recommendation from the Economic Summit
of Industrialized Nations Working Group on Growth, Technology, and Employment's Panel of
Experts on Satellite Remote Sensing, which recognized the multidisciplinary nature of satellite
Earth observation and the value of coordination across all proposed missions. The main goals of
CEOS are to ensure that: (1) critical scientific questions relating to Earth observation and global
