This Union Session will highlight international space agency plans on current and future planetary exploration including Earth as seen by ESA, NASA, JAXA and the Russian Space Agency. We will highlight flagship missions observing the Earth and other planetary bodies and discuss the challenges of organising future missions in an international framework as well as a forward look at potential future candidate missions. The first three presentations focus, primarily, on Earth Observation missions and the following three on planetary and solar system missions. Speakers include the directors of Earth Observation and Planetary Science from ESA, NASA, JAXA and the Russian Space Research Institute.
