The main objectives of this study were:
- To carry out thorough analysis and modeling of the anomalous gravity fields expected from lunar lava tubes and other types of void spaces, of various sizes and depths. This work was carried out by geoscientists from Queen’s University.
- To define the mission and system-level requirements for this exploration mission, derived from the scientific analysis of those expected gravity signals, and specifying feasible mission and system-level designs, for a mission to scout the Marius Hills pit crater.

The DAEDALUS mission concept aims to explore and characterise the entrance and initial part of lunar lava tubes within a compact, tightly integrated spherical robotic device, with a complementary payload set and autonomous capabilities. The mission concept specifically addresses the identification and characterisation of potential resources for future ESA exploration, the local environment of the Moon's subsurface and its geologic and compositional structure.

 This study investigated the semi-autonomous exploration of a lunar skylight cavity.

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.
