Launched on 17 March 2009, ESA's Gravity field and steady-state Ocean Circulation Explorer (GOCE) mission was the first Earth Explorer mission in orbit. This novel mission delivered a wealth of data to bring about a whole new level of understanding of one of Earth's most fundamental forces of nature ? the gravity field.
Polar Orbit Earth Observation requirements have been considered for the Space Station era. Candidate model payload groupings (both an initial set and an evolutionary growth) have been derived assuming the availability of serviceable permanent polar platforms, e.g. a "morning" platform provided by ESA, and an 11 afternoon" one by NASA.
The purpose of this plan is to summarise the essential steps to be undertaken, over the next decade, by a global community of nations and intergovernmental, international, and regional organisations, to put in place a Global Earth Observation System of Systems (GEOSS).
