This purpose of the study was to develop a high frequency radar to sound the first tens of metres of asteroid regolith and to achieve 3D tomography with metric resolution in order to
- Determine its structure and layering
- Identify geomorphological elements (rocks, boulders, etc.) embedded in the sub surface
- Map the spatial variation its texture
- Derive an estimate of dielectric permittivity of the sub-surface material

The latest advances in the Additive Manufacturing technologies development lead to expand the application field. It is particularly well adapted to satellite which combine complex parts and small series production. Such technique provides additional freedom for design and opportunities of number of parts reduction, functions integration and development plan shortening for example.

The purpose of this GSP activity was to assess the capabilities of non-intrusive diagnostic techniques for internal measurements in ablative materials during PWT tests. This initial steps were to identify the measurements to be performed in relation with high-speed Earth re-entry, and to identify the accessible parameters as well as related diagnostics techniques. For this objective an extensive review of the possible measurement methods, with a focus on non-intrusive diagnostics, has been undertaken.

Biomass burning is a key Earth system process, a major element of the terrestrial carbon cycle and a globally highly significant source of certain atmospheric trace gases and (primarily fine mode) aerosols. Natural and anthropogenic biomass burning occurs on all continents except Antarctica, with an estimated average of 3.5 - 4.5 million km2 of vegetation burnt in global wildfires each year (though this does not include the very large numbers of "small" agricultural fires that are difficult to map using current coarse spatial resolution remote sensing datasets).
