This study aims to carry out the conceptual design of a large-parabolic-antenna reflector that is manufactured and assembled on-orbit.

Through its Clean Space initiative, ESA has been devoting an increasing amount of attention to the environmental impact of its activities, including its own operations as well as operations performed by European industry in the frame of ESA programmes. In its Technology Strategy, ESA identified 'Inverting Europe’s contribution to space debris by 2030' as one of the four technology development targets.

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.

In this report we document the development and deployment of an individual hopper intended as a precursor survery mission for planetary exploration.

The objective of the study was to investigate the performance and shielding abilities of lunar regolith-based geopolymer when reinforced with basalt fibres and cured under environmental conditions of the lunar surface. The geopolymer building materials should be suitable for
3D-printing on the Moon. Since there is a very limited supply of water on the moon, the study also focuses on lunar geopolymers with a reduced amount of water in the recipes, without the need for raw materials that cannot be resourced locally on the Moon.
