In order for off-Earth top surface structures built from regolith to protect astronauts from radiation, they need to be several metres thick. With support from European Space Agency (ESA) and Vertico, the Technical University Delft (TUD) advanced research into constructing habitats in empty lava tubes on Mars in order to create subsurface habitats. By building below ground level not only natural protection from radiation is achieved but also thermal insulation because the temperature below ground is more stable.

In this activity, lunar regolith simulants were characterised based on their thermal behaviour, particle size distribution and composition, in order to inform the choice of consolidation method for functionally graded materials (FGMs) – powder characterisation results are provided in the 'conference paper' deliverable.
Firstly, an extensive literature review study (deliverable 'Literature Review') identified Digital Light Processing (DLP) and Spark Plasma Sintering (SPS) as promising consolidation techniques.

A major challenge in the field of control is to achieve reliable, aggressive, high-speed control of autonomous vehicles. In space, this may involve spacecraft that need to land under harsh conditions, or even – in an extreme scenario – negotiating asteroid debris fields at high speeds. On Earth, the exemplar task that draws most attention currently is high-speed autonomous flight of drones. The application of optimal control on board limited platforms has been severely hindered by the large computational requirements of current state-of-the-art implementations.
