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.

This report compares the needs of Arctic stakeholders (as articulated in policies and strategies) with the contribution different types of satellite technologies (communications, weather, navigation, earth observation, surveillance, and science) can make to meet current and future requirements. It will help the European Space Agency (ESA) understand Arctic issues, increase the synergy between ESA activities and Arctic initiatives, and assist ESA in preparing relevant Arctic related programme proposals to meet future requirements. The Arctic is changing.
