The NASA DART and the ESA Hera missions will allow performing the first complete asteroid deflection test by a kinetic impact, including the full characterization of the target and the impact outcome. The development of these missions is supported by a large number of activities in terms of modeling (impact process, dynamics, physical properties), instrumentation, close proximity operations and data analyses. In parallel, the inventory and spectral properties of Near-Earth Objects from Earth and from space (NEOSM) will progress substantially. This session welcomes contributions related to those fascinating topics.
