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.

Hybrid infrared detector arrays combing a sensitive diode layer bonded to a CMOS readout circuit are baselined for many current and upcoming Earth Observation missions. This activity aims to develop a breadboard, using a custom ASIC, capable of providing the necessary clocks and bias voltages to operate the detector as well as providing 4-channel video processing and digitisation, leading to a two-chip (Control ASIC + hyrbid detector) detection system. The design will be split to allow separate or combined use of bias and clock generation and video processing and digitization functions.

The VHF Data Exchange System (VDES) is a future maritime communication system with the principal objective of enhancing maritime communication applications, based on robust and efficient digital transmission with wider bandwidth than Automatic Identification System (AIS), with a data rate up to 32 times the current AIS. As for AIS, VDES is mainly a ship-to-ship and ship-to-shore system. The ship-to-shore system will use the terrestrial VDES infrastructure that will extend the VDES coverage to only around 60 km from the shore.

Methane is formed as a product of air revitalisation onboard spacecraft (Sabatier reactor) and also within the MicroEcological Life Support System Alternative (MELiSSA). By its nature, the methane molecule represents a mass in carbon and hydrogen. As these two elements are core elements of organic chemistry, they deserve to be seriously studied for the closure of life support system cycles. Unfortunately, today methane is known to be an end-product of the said recycling processes.

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.
