New L2 missions like Euclid and Plato will require high data rate reception in K-Band downlink (26 GHz). A new X/K-Band coaxial feed system was developed in a previous TRP activity and it will be deployed in the next years in DSA2 (Cebreros, Spain) and DSA3 (Malargue, Argentina). This feed system architecture will be considered the starting point for the re-design of a new feed system that will allow simultaneous uplink (22 GHz) and downlink (26 GHz).It is intended to trade-off at least two alternative feed system architectures and to perform the detailed design of the selected one.

The aim of this study was to investigate potential small mission architectures that would further ESA's exploration objectives at Mars post-Mars Sample Return (in the 2030s) or potentially in parallel with MSR (if sufficiently low cost).

GNSS and other positioning systems are expected to have a very important role in Smart Cities. In this context, the design of the high-level architecture of a testbed to support future applications of GNSS and other positioning systems in Smart Cities is of high interest. The design of this testbed shall consider as baseline the availability of a network of distributed smart sensors, which are remotely accessible and configurable from the cloud, and existing network infrastructures shall be considered.

Space mixed-signal radiation tolerant front-end performance for sensor and control for instrumentation and AOCS are limited by the supply of disparate analogue and mixed-signal components.

CRANE is a study commissioned through the OSIP lunar caves Campaign that examined the possiblity of using a crane to investigate lunar caves via lunar pits. The crane would be mounted on a rover that would need to be placed close to the pit.

Light-trapping helps enhance the light absorption in space solar cells and hence enables their thickness to be reduced to increase the radiation hardness. We have optimised light-trapping structures (LTS) inspired in the diatom frustule and moth’s eyes. As a solar cell reference, we use the commercial 3G30C model from Azure Space Solar Power GmbH. We have developed a physical model to describe the solar cell absorption and derive the efficiency. The optical description relies on the Fourier modal method and the solar cell performance on the detailed balance limit.
