Aerobraking phase of ENVISION is critical in terms of duration and required operations. One limitation during aerobraking is the temperature reached on Multi Layer Insulation (MLI) due to the aerothermal heat flux.MLIs can withstand during short durations (intermittent exposure) higher temperatures than their steady state qualification temperature.

The interest of having in the near future an available Position, Navigation and Timing (PNT) service supporting future missions to and at the Moon is currently supported by both institutional and commercial initiatives. On the commercial side, multiple companies are developing business solutions targeting the Moon and several major European companies are proposing to team up to build a communications network on the Moon compatible to terrestrial standards. In parallel, NASA has recently announced its plans to a ?Return to the moon?

The idea concerns a new photo-bioreactor that contains bacteria immobilized on solid substrate. Some red bacteria, like Rhodopseudomonas palustris, are able to produce gaseous hydrogen from water using only light as energy source through the so-called anaerobic photosynthesis. Moreover, these bacteria degrade organic contaminants contained in the water to carbonic acid and hydrogen photo-evolution. CO2 can be recovered from the water and eventually sent with Hydrogen to biomethane production by Sabatier reactor.

All satellites must have the ability to correct for the high rotational tip-off rates after initial release from the launch vehicle. On current navigation satellites, de-tumbling is usually achieved in short duration using the onboard chemical propulsion thrusters. With future Navigation satellites looking at using all-electric propulsion satellites, these manouevres are to be performed by xenon-fed auxiliary thrusters. COTS (xenon cold gas) auxiliary thrusters are limited in the max thrust level provided and the de-tumbling duration, in the absence of chemical thrusters, is a concern.

The use of higher frequencies is becoming necessary for supporting feeder links of High Throughput Telecom Satellites due to the larger bandwidths available. Q and V bands are now being considered as a baseline for next generation systems. The next step will be to look at W band. In order to understand the system sizing, it is necessary to have a good modelling of the propagation channel. So far no measurement campaign has been done, therefore it is needed to start characterizing the channel.

The core objective of MBSE-IT was to provide a digital link between ground segment systems and the infrastructure on which the software is deployed and it was implemented by the definition of a physical deployment model for the system as a dedicated viewpoint on the overall system model for the ground segment.

This de-risk activity has successfully demonstrated that the use of the component level length scales over compound length scales in the calculation of heating rates can lead to a significant over-prediction in component temperatures.

Microbial contamination is a generic risk concerning flight hardware degradation, Planetary Protection and potentially crew health. Material surface requires a proper control and monitoring of the microbial cleanliness level. Today, contact plates, swabs and wipes are used for surface sampling. Swabs and wipes samples include mandatory liquid transfer to further extract and detect microorganism. Today, automated miniaturized system, molecular-based, has been developed and offers the possibility to perform multiple laboratory functions on a complete integrated system (i.e.
