In this report, we describe the advisory study for both the Asteroid Impact Monitoring (AIM) as a stand-alone European mission and for AIM with its second component, the US Double Asteroid Redirection Test (DART) mission under study at NASA by the John Hopkins University Applied Physics Laboratory.

In the first demonstrations, the detection of photons with graphene was based on the pn-junction generated by the graphene-metal contact. There the active detector area is a narrow line with length determined by the contact edge and as the absorption of photons incident to a single layer of graphene is 2.3 % at highest, the detector efficiency is rather modest. However, the detector has very high speed, demonstrated up to 40 GHz and predicted to reach over 500 GHz, possibly limited only by the contact resistance.

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.

Water resources management has become a challenging problem worldwide, especially in developing countries. The lack of information on land cover monitoring has a huge impact on the water resources management, since it may hamper the collection, treatment and distribution of water for human consumption and agricultural development. To fulfil this demand, Earth Observation (EO) data has been used in African countries to map land cover of large and often inaccessible areas, providing useful information on qualitative and quantitative land cover changes.
