This session comprises of a set of invited presentations that focus on the use of space in geosciences. Space platforms are key for planetary and space sciences, but also Earth sciences, e.g., atmospheric, marine, or geodetic research, and to many applied fields such as natural hazards and environmental monitoring. The political aspect of the use of space is highlighted by the European space policy institute, whose research provides independent analyses on mid- to longterm issues relevant to the use of space.
