PoPSAT (Polar Precipitation SATellite)
The terrestrial water cycle is a unique system on planet Earth. It is directly influenced by our changing climate with most drastic effects in the polar regions. A main element of the water cycle is precipitation, and it is only very sparsely observed at high latitudes. We propose a new satellite mission, POPSat, to observe snow and light rain at high latitudes, as well as snowfall at mid latitudes. The satellite will be equipped with a dual band (Ka and W bands) phased array antenna radar and provide 3D information about precipitation and clouds. The horizontal resolution of 2 km will exceed all other observations, and the measurements at high latitudes, together with the capability to monitor snowfall, will complement the GPM missionтАЩs observations. By filling this gap, POPSat will provide essential data for improving global weather and climate models

Chemical and Textural characterisation of two Phobos regolith simulants
Phobos, the larger of MarsтАЩ moons, is scientifically important because it holds clues to Mars system planetary formation processes, and its regolith may hold a detectable fraction, up to 250 ppm, of material ejected from the surface of Mars. This material, delivered to Phobos throughout its history is representative of MarsтАЩ surface over geological time, and may preserve martian crust, potentially containing biosignatures, that have otherwise been altered by changing geological processes on Mars. Future missions, such as JAXAтАЩs Martian Moons eXploration mission (MMX), aim to test these hypotheses and provide further understanding of PhobosтАЩ viability for in-situ resource utilization and its effectiveness as a record keeper of martian biosignatures. However, in the absence of direct sampling or analysis of PhobosтАЩ surface, regolith simulants are required. Physical simulants can be used to aid mission engineering capability testing and the identification of potential contaminants. Compositional simulants support investigations into planetary protection and biosignature preservation, and assessment of the accuracy and reliability of analytical techniques to be used on future samples from Phobos.As a part of ESA-funded concept studies, physical and compositional simulants were designed and produced. Achieving the desired physical and compositional characteristics were balanced against material availability, cost and safet
