The PERSEO project (PErsonal Radiation Shielding for intErplaetary missiOns) aimed at
studying a wearable innovative radiation protection system to mitigate the effects of
Solar Particle Events (SPE) on astronauts. SPE can be considered as related mainly to
deterministic effects of the cosmic radiation, with hazards to man arising for physical
doses above 2 Gy, when symptoms of the hematopoietic syndrome appear.

The objective of the study was twofold: i) to analyse the new dynamics of desertification in Southern African region (southern Mozambique, southern Zimbabwe and Northern South Africa) through main achievements of the DesertWatch-Extension; ii) to propose new methods for integration of EO data with different spatial and spectral resolutions, namely the new ESA Proba-V mission, and new field data, in particular, the map of risks on natural disasters in Mozambique.

Generally speaking DIAMS has been an opportunity to secure the feasibility of the IOD in technical, programmatic and financial terms. More specifically DIAMS has allowed to define the end-to-end mission concept for this IOD, covering the design of various associated segments : Space Segment (Payload, Platform), and Ground Segment. Both interest and programmatic aspects have also been consolidated.

- On the technical plane :
Both the requirements and the design of the system have been refined to validate the IOD concept :

Satellite based optical communications in space is rapidly progressing, involving an increasing number of flight validations in LEO, GEO and beyond. Various space agencies successfully demonstrated both, optical Inter-Satellite communication Links (ISL's) which have been validated in flight experiments since 2001 and direct-to-Earth (DTE) optical communications.

The scientific goal of the study was the investigation of the
electromagnetic and mechanical response of relevant basalt-like
materials after near-field radiation exposure, to assess the performances
of microwave-assisted drilling technology.

The scope of the project was to investigate and develop suitable strategies for the development of nano-enabled fibre reinforced plastics (neFRP) in order to produce materials tailored to the customer's needs and requirements. Within the scope of the work was also to establish a quality control system to assure that the produced products are of acceptable quality and can be integrated in functional parts for space applications.

Additive manufacturing (AM) is a manufacturing technology that allows significant flexibility in the
complexity of a design. The implementation of this technology has a large variety of capabilities for
components/ subsystems including

The Medium Earth Orbit (MEO) region, home of the operational Global Navigation Satellite Systems (GNSS) GPS and Glonass, is becoming more and more exploited with the advent of the European Galileo and the Chinese Beidou constellations, both in their build-up phase. The sensitive applications of the navigation satellites and the absence of any natural sink mechanism, such as the atmospheric drag, call for a careful debris prevention policy able to preserve the MEO environment, avoiding in the future the problems now already faced by the LEO and the Geostationary Orbit (GEO) environments.

All spacecraft in Earth orbit are exposed to the risk of impact with Micrometeoroids and Orbital Debris (M/OD). Because of the large collision velocities, Hypervelocity Impacts (HVI) with M/OD may cause significant damage to various subsystems and components up to mission failure.

The overall objective of this study is to assess constellations of two pairs of satellites for the retrieval of time-variable gravity field information for best quality scientific monitoring of mass distribution and transport in the Earth system. Before embarking on this study the geodetic community and space agencies have come to realize that weaknesses in current single-pair gravimetric satellite missions such as GRACE or GRACE-FO (to be launched in 2017) would significantly be alleviated by having a second GRACE-type pair in space simultaneously.
