A new approach to produce oxygen from the Martian atmosphere is proposed, linking two emerging technologies: non-thermal plasmas and ion-conducting membranes. Microwave plasma sources lead to high conversion rates and enable plasma ignition with light and compact solid-state generators. The unique pressure and temperature conditions on Mars are favourable for plasma CO2 decomposition, and the experiments and simulations carried out anticipate a competitive oxygen production per mass and volume of hardware in a future prototype.

The term Digital Twin is a hot topic in the simulation industry. Examples of digital twins in other comparable domains are for health monitoring of vehicles or gas turbines. The proposed activity aims to apply the ideas of digital twins, with a specific focus on spacecraft thermal control systems (TCS). A set of possible use cases is provided below with expected benefits:

    EXOMARS features a multi-stem drill, pioneered by the MIRO driller (TRP result in 2001), capable of acquiring samples 2 meters down in the ground. Multi stem drills are the right solution for shallow depths, however for reaching deeper they present problems that are too difficult to solve within the constraint of space missions. Drillers of this type require a cumulated length of pipe as long as the depth reached, which translates into a large mass. Furthermore friction increases with depth so for any drill larger than few meters, the well must be lined.

    Magnetic materials, both with soft and hard magnetic behavior, are key components in many devices aboard any spacecraft, such as motors, mechanisms, actuators and sensors. The most common route for the manufacturing of magnets is the sintering process, which produces the highest magnetic performance possible but it is energy intensive and requires molds for each geometry. The alternative is the use of bonded magnets, which are composite materials composed of a polymeric matrix with a high content of magnetic filler.

    Composite and adhesive resin systems form a cornerstone for the manufacture of any modern spacecraft however both the manufacturing and procurement processes are often limited by the pot and/or shelf life of the prepreg/resin materials. A longer shelf life could mean a reduction of the amount of scrappage which occurs from any typical spacecraft composite system manufacturing line. Typically, it can be necessary to scrap and re-procure significant quantities of unused prepreg or resin materials simply because the shelf life is shorter than any recurrent manufacturing.

    Uncontrolled spacecraft re-entry requires the satellite to sufficiently demise in order to meet the casualty risk requirement. Heat generated during re-entry is not adequate to sufficiently demise some spacecraft equipment.
    - Equipment (e.g. Large mechanisms, magnetorques, optical equipment) is hard to demise without big design changes as the functionality requires using metals with high melting temperatures.
    - Earlier break-up of the interface of equipment to the structure, harness and pipework is beneficial for demisability.
