Investigation of Active Detumbling Solutions for Debris Removal

The main objective of this study 'DETUMBLING – Investigation of Active Detumbling Solutions for Debris Removal' was to propose and investigate a contact-based de-tumbling strategy using a robotic arm. Realistic models were developed for the chaser with robotic-arm, target and composite systems. Specific GNC strategies were developed for the different phases of the mission: robotic-arm deployment synchronisation with the target de-tumbling the composite.

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.

Development of a dual-channel depolarization lidar technique for the derivation of CALIPSO/Aeolus/EarthCARE-related conversion factors

DEDICAtE, aims to the development of a dual-channel depolarization lidar technique for the derivation of CALIPSO/ADM-Aeolus/EarthCARE-related conversion factors. CALIPSO is capable of retrieving linear particle depolarization ratio at 532 nm in a global scale, providing this well- calibrated product since 2006. Future ESA missions EarthCARE and ADM-Aeolus are based on the employment of the High Spectral Resolution polarization-sensitive lidar technique at 355 nm.

Energetic Neutral Atom Imaging for Space Environment Monitoring

ENSEM investigates potential use of energetic neutral atoms (ENA) for space weather monitoring. ENAs are produced everywhere in the solar system due to the interaction between space plasma and ambient particles (neutrals and other plasma populations). Due to the neutrality, ENAs fly straight, keeping the information of the source plasma. Thus, ENAs are expected to visualize the plasma in a remote sensing manner.

Application of the FAIR facility to space radiation research

The radiation environment in space has severely adverse effects on humans, electronics and materials. The most challenging part of the environment for our understanding of the effects are the highly charged highly energetic (HZE) particles. This study looks at the possibilities FAIR offers for space radiation research. There are two main parts: first the open issues and needed research in space radiation involving heavy ions of high energy and second the requirements a facility for this research should meet checked against the possibilities at FAIR.

GNSS-R – Assessment of Requirements and Consolidation of Retrieval Algorithms (GARCA)

The main goals of the GARCA project are:

(1) To develop a tool capable to simulate GNSS-R data products for various instrument implementations using state-of-the-art techniques, including GEROS phase-A candidates, up to Level-1 observables and Level-2 geophysical data products, which will be freely and easily accessible to the interdisciplinary scientific GEROS community.

(2) To study the compliance of different GEROS implementations with respect to the Mission Requirements, and study the optimization of its geophysical data products.
