We have continued our shock physics code calculation studies of DART-like impact events. This includes comparisons of iSALE and SPH code calculations, using a range of strength and structural properties. The effect of porosity was studied in detail by applying different crushcurves, representing materials with varying crushing strength. The crushcurve was found to have a large influence on the outcome, in particular the ejecta properties and momentum transfer.

Humankind tested its capacity to survive on the Moon’s surface for short periods of time through the Apollo missions almost 50 years ago. Since then, robotic missions to the Moon have spent periods lasting several days and nights on the satellite. However, many technological challenges arise when planning a lunar (robotic and/or manned) mission that is fully operational during the night. Among these challenges, the need for a power supply system for both day and night remains open.

The project aimed to establish a structured approach to an optimised part or component by applying Concurrent Design methods. It intended to incorporate all necessary disciplines and competencies that are required for a potential spacecraft part. Within the activity, advanced manufacturing included various novel techniques, not only additive manufacturing. It means that the Concurrent Design approach was developed for the engineering of units to be built with a broad range of advanced manufacturing technologies.

Earth observation by satellites provides essential datasets for a wide range of commercial, societal and scientific applications. Satellites have been observing the state of the environment since the launch of the radiation balance instrument on Explorer 8 in October 1959, and over the last 60 years the range of observation types and applications has grown exponentially. Today operational long-term sustained Earth observation programmes, exemplified by the Copernicus Sentinels, give a wide range of users reliable environmental information services.
