Automated monitoring of geohazards using Sentinel-2 time series in montainous regions

Slow-moving landslides are of particular threat in many areas around the world, with large impacts on infrastructures and populations. In this project, we aim at developing the tools to detect them and monitor their activity with time, using optical sensors.

Development of graphene based THz and X-ray radiation detectors - parallel 2

Previous research has already demonstrated that graphene field effect transistors can be operated at incredibly high bandwidths, demonstrating 25+GHz with a theoretical limit of up to 500GHz for visible photodetection. Ultrafast photodetection has also been demonstrated on the 10s of femtosecond scale via the photothermoelectric effect for visible photodetection.

Future Concepts for Galileo Search-and-Rescue Space and Ground Segment (Parallel b)

While the MEOSAR is moving to FOC with Galileo satellites that are equipped with SAR transparent payloads, ESA is already investigating its future Galileo-2 (G2G) system for new features. In this framework, one of the aims of the ESA study on Future Concepts for Galileo Search And Rescue was to define a preliminary design of a new SAR payload capable of processing both First Generation Beacon (FGB) and future Second Generation Beacon (SGB) signals.

System impacts of propulsion Passivation

Propulsion passivation is most of the time feasible for running missions, using thrusters and existing AOCS modes, whatever the number of tanks and for both monopropellant and bipropellant systems.
For monopropellant systems the propulsion passivation may be:
-Partial for tank(s) with membrane. All the hydrazine under the membrane may be depleted but the pressurant gas above the membrane cannot be depleted. The final tank pressure is close to typically 5 bars at the end of mission.

Micro/nano encapsulation technologies

Funded by the European Space Agency (ESA) through its General Studies Programme (GSP) (www.esa.int/gsp), this activity aimed to provide more insights on the possible space applications of micro- and nanoencapsulation (MNE) techniques and technologies. NASA performed some early studies3,4 in the international space station (ISS) with aim to assess whether new drugs could be produced under a microgravity environment. However, the study of MNE in the space context remained primarily limited to these few experiments.
