The beginning of Earth-system studies from space began in the late 1950's and progressively improved into the 1970's due in large part to efforts at Goddard and people like Bill Nordberg.  Based on these improved capabilities the NASA Earth Observing System (EOS) was founded and is now producing some truly remarkable and wide-ranging results. Included within that array of results extensive and useful  observations of land, ocean, and atmospheric parameters, processes and trends are now available after over 6 years of operations by the Terra MODIS instrument and over 4 years by the Aqua MODIS instrument.  It seems more and more clear that after the NASA EOS era many issues beyond science and technology will have to be engaged and understood by scientists and engineers to gain the requisite support for developing and implementing improved technology leading to better understanding of the future for the Earth and its inhabitants.
