Lunar regolith can be sintered/melted by intensive solar or laser radiation to dense and rigid structures. For reaching the required energy densities, sunlight can be focused by means of mirrors or lenses. In the present study, solar radiation is simulated by a CO2 laser system, providing a maximum power output of 12 kW cw. The laser has been used to generate large laser spots of 50 mm respectively 100 mm. In both cases a parallel laser beam with the same diameter of the laser spot has been generated to make the spot diameter independent of the distance to the target powder.

As proved in several missions, the Lorentz force acting on the electric current carried by a space electrodynamic tether (EDT) can be used to propel spacecraft without using propellant. State-of-the-art EDTs involve a bare tape for passive electron collection (anodic contact) and an active device, or a tether segment coated with a low-work-function material, for electron emission (cathodic contact).

In this project, the University of Luxembourg studied and evaluated a new concept of connecting space missions via space internet providers. The system requirements, necessary adaptations, and possible limitations are provided and discussed. Three types of space internet provider were studied and evaluated: Starlink, OneWeb and O3b mPOWER.

The main advantage of the proposed design of middle resolution class analog to digital conversion for space application is minimal demand for additional special function/parameters components (single middle class op-amp, resistors and capacitor are enough). All other required functionality, including analog signal comparator and reference switching, can be implemented in FPGA digital subsystem for middle resolution range applications. This makes the choice of space mature/proven components easier.

Large aerospace projects require the collaboration from many partners, which often use their own development tools and frameworks. The validation of such projects relies heavily on test automation to increase the quality and reduce the costs. Unfortunately, the automated tests developed by each partner typically only address their specific activity and rely on specific tool. Over the past few years, several frameworks to support the automated testing and validation of the different parts of a space project have been produced and deployed.

Ground Stations and Telescopes are often in remote geographical locations. The local staff do often not possess the required skills and/or knowledge to perform all tasks related to configuration, maintenance and operation of the hardware equipment. As a result, more experienced engineers must travel to the sites to perform the respective tasks.
