Commonly used classical cryptographic protocols, such as the RSA-protocol, rely on the hardness of computational problems. With the advent of quantum computing (QC), the hardness assumptions of these problems is nullified, since they can be solved efficiently on a QC. On the other hand, the security of Quantum key distribution (QKD) rests upon the very laws of physics and guarantees information-theoretic security, which not only enables tap-proof communication at present, but also prevents any future technology to crack encrypted messages.

The goal of this study was to develop a design for a lunar habitat in the close vicinity of one of the lunar poles and to demonstrate the feasibility of the suggested design in view of the available resources. The habitat should operate self-sufficiently in the long term by producing and recycling its own oxygen and food inside large greenhouses and almost exclusively by using solar irradiation power. The proposed concept features a combination of:
Pneumocell
The main objectives of this project were to develop a thruster prototype based on magnetic powder electrostatic propulsion and to test it in vacuum with direct thrust measurements. The aim was to check the robustness of the concept and to measure and calculate important performance parameters such as thrust and specific impulse, to allow a comparison with other thruster technologies. This project demonstrated for the first time the feasibility of electrostatic propulsion based on powder emission.

SMARTIE (Smart Resource Management based on Internet of Things to support Off-Earth Manufacturing of Lunar Infrastructures) is an ESA study to assess the requirements, architecture, hardware and software needs and costs for implementation of an Internet of Manufacturing Things (IoMT) for a lunar human base and associated infrastructure.
Liquifier Systems Group
The first steps have been taken to establish a non-explosive, harmless Indium-based 100W electric propulsion system for small and medium satellites. The activity successfully developed a breadboard that included all necessary functions for controlling a micro thruster, including temperature sensing and control, generation of the high voltage supplies for the ion emitter and extractor as well as heating and bias voltage supply for the charge balancing.

Activity with GSTP and RUAG, Austria, to develop a thermal insulation suitable for planetary landers and rover.
An extensive trade-off of on various materials was carried out and supported by full material characterisation tests. Two insulation concepts were selected: foam and a gas gap.
The technical solutions are light weight, flexible and can be applied directly on the external/internal walls, wrapped around electrical cables and to mechanisms

The initial step of the analysis is represented by the definition of the GNSS capabilities and receiver requirements in the environment of interest. The service volume concept has been introduced to this aim, and recent studies pointed out the interest to define and include GNSS performance above the altitude of the constellation itself [1], [2]. It is well known that signals, even if primarily broadcast from GNSS sources in order to serve Earth surface and proximity (i.e. with a beam directed nadir), are available at a limited extent also above the constellation.
