The study will be focused on the developing of 5A 1200V Silicon Carbide (SiC) Schottky diode in hermetic package with the main goalto characterize the performances of the devices in terms of switching capability, reliability of the technology and main characterization of static and dynamic parameters as a function of temperatures as well as to characterize the thermal impedance and resistanceof the proposed package solution. The device will also be characterized the tolerance of the device to Total Ionizing Dose (TID) and proton fluence in order to evaluate their potential future application in space missions. The goal is having a device whose electrical characteristics are enveloping the performances of the devices already available on the market: - Zero Reverse Recovery Current - Zero Forward Recovery Voltage - Temperature independent switching behaviour - Low figure of merit QC/IF where QC is the totalcapacitive charge (goal is QC<20nC) - Package in TO-257 or LCC style As one of the main feature of SiC compound is the high thermalconductivity (around twice the Si one) the maximum operating junction temperature and consequently the maximum power density is expected higher with respect the Si devices.

The reliability of the developed diodes should as well be assessed in this study establishing a limit for the junction temperature for reliable operation as well as the thermal properties of the package At the present stage, the SiC Schottky devices have been already commercialized for mainly automotive market, but the developing and evaluation of anhermetic 1200V SiC Schottky diodes would be appealing for TWTA and other space voltage space application due to the demonstrated performances of the devices on the market. The study will be organized with the following work structure:
-Phase 1: critical analysisofthe technical requirements, compliance matrix of goal values for the main key parameters
-Phase 2: trade-off analysis of the main design structure and topology with relevant simulation
-Phase 3: manufacturing processes definition and main trade-off analysis, first issue of draft Process Identification Document (PID), first run in foundry
-Phase 4: Electrical characterization and stability verification of first run in foundry and analysis of the results

The objective of the activity is to conceptually assess a tentacles based capture mechanism for debris removal and to bring the design to a PDR level. The activity involves several trade-off: - mechanisms design, - deployment scenario, - capture scenario, - adequacy of the mechanism to properly withstand the deorbiting & re-entry loads - selection of adequate set of sensor to obtain an autonomous capture mechanism. The interaction will the AOCS sub-system shall be also considered through adequate multi-body simulations, so to answer questions like: to which level the relative motion between the chaser and the target can be minimised? And is the capture system robust to unwanted early collision between the chaser and the target ? As a study case for the requirements, a mission similar to Envisat shall be studied and, to make the tentacles mechanism of general applicability, the capability to grasp the launcher I/F cone shall also be considered as a requirement. A baseline design for the mechanism shall hence be selected. and in preparation for the next step, the design details shall be identified up to a PDR level.

Ocean Surface Currents (OSC) are the coherent horizontal and vertical movement of surface ocean water (over a specific depth regime) with a given velocity and an upper boundary in contact with the atmosphere that persist over a geographical region and time period. The user portfolio for OSC measurements is extensive and includes: ship routing, offshore operations, ports and harbours, maritime pollution, ice forecasting, maritime search and rescue, offshore renewable energy, wave forecasting, operational oceanography, weather forecasting, sailing, navigation, hydrographic offices and navigation, fisheries, aquaculture, marine infrastructure design, environmental protection, oceanography and climate amongst others. OSC can be derived from space using a variety of techniques including altimetry, gravimetry, SAR radial Doppler, optical (VIS and TIR) feature tracking, passive microwave measurements, ice movement,inferred from scatterometry, and sun-glitter patterns. Sparse in-situ measurements including drifting and moored buoys, buoys, coastal HF-RADAR installations, ARGO floats, and ship measurements complement satellite measurements. Not all of these techniques have reached full maturity: each measurement technique has specific characteristics (e.g., resolution, coverage, accuracy, depth integration etc) that are complementary and there is scope for development of enhanced novel products, particularly through data merging and synergy.

The ESA Data User Element (DUE) is a programmatic component of the Earth Observation Envelope Programme (EOEP) with a mission to encourage long-term relationships between the user communities and Earth Observation. Against this background, the work-programme of the GlobCurrent project is intended to improve the uptake of satellite-derived OSC data by the scientific, operational and commercial user community. GlobCurrent includes the following activities: 1. Develop a framework (inter-comparison and trade-off analysis of algorithms and methodology) to use two-dimensional surface manifestations of OSC to infer the three-dimensional surface ocean (<50-100m) circulation through data-driven merging and synergy. A critical aspect will focus on understanding the information content of each technique in terms of OSC and how complementary data can be combined in the most optimal manner in a data-driven framework to support modelling. 2. Provision and maintenance of a uniform, harmonised, quality controlled, multi-sensor set of satellite OSC data and ancillary information (L2/L3), in a common format, with consistent characterisation of errors and biases. 3. Inter-comparison of OSC data with colocated in-situ measurements, ocean model data and cross characterisation between different satellite datastreams to establish product error and bias methodologies/information (uncertainty). 4. Provision and maintenance of merged (L4-synergy) OSC products (data driven) based on synergy between different satellite and in situ data at local, regional and global scales for user-driven applications including uncertainty estimation for each grid point. 5. Implementation of an integrated set of user-driven demonstrators based on satellite OSC data, and the operation and maintenance of these demonstrators for a finite period, to help the global user community make full use of satellite OSC data, to facilitate scientific, operational and commercial exploitation. 6. Development and maintenance of a GlobCurrent web portal providing a single point of reference for satellite and in situ OSC data together with associated documentation, search and data access, OSC community information, data calibration and validation information.

Materials used on launcher stages are at the best inert or possibly have adverse effects to the environment after return on ground.Environmental impact can be improved per design with the potential to: - Introduce positive effects to the environment in case the materials serve as biological nutrient - Improve costs as possible commercial solutions are developed primarily for the mass market Some materials applications on launchers are a promising target because the life-time is very limited, including storage under very controlled conditions, and short atmospheric exposure. The aim of this activity is to - Identify promising target applications (e.g.the external ESD paint) - Develop for each application on small scale an alternative biodegradable materials solution - Test thecompliance with adequate launcher requirements - Demonstrate ecological and economic benefit.

A completely closed life support system today cannot be considered without food production and waste recycling (i.e. food production systems have in average an efficiency of 60%, the rest being waste). Current nutrition requirements are aiming at a very accurate food quality (i.e. minerals content, carbohydrates content, amino-acids profile, fatty acids profile). Yet bed rests have demonstrated that existing knowledge and tools allowed limited prediction of meal nutritional composition and subsequently food quality. As a matter of fact, the discrepancy between prediction and actual food nutritional content was mainly due to the vegetal (i.e. plants) elements. In a general manner, the complete food production and preparation chain, which starts with the plant seed and ends with the ready-to-eat meal, impacts the food quality at several stages (i.e. plant growth conditions, harvest, storage, processing, cooking, etc.). However, this impact is today poorly understood or controlled. Moreover, modelling of food production systems are today limited to very specific and independent plant metabolisms (C and N uptake, light utilisation, etc.) but almost no knowledge exist at the overall plant level. Consequently a strong effort of plant and food characterisation is now necessary for a better understanding and control of the complete MELiSSA loop.

The activity will establish an advanced Guidance, Navigation and Control (GNC) concept for active debris removal for the baselined capturing technologies. The activity will include the preparation of a simulation environment (model in the loop) for verification of feasibility from a GNC perspective. This activity will assess scenarios for active debris removal stemming from the baselined capturing technologies and derive a preliminary, advanced guidance and control concept for the phasing, approach, fly around, capture and deorbitation phase (TRL 3). This will include trade-offs concerning the required sensors as well as actuator and the architecturaldesign. Following the assessment of attitude and positioning requirements, the activity will continue with algorithms analysis and evaluation for image recognition, pose identification, path planning and GNC at large. The activity will include the preparation of a simulation environment (model in the loop) for verification of feasibility from a GNC perspective. Particular emphasis will be placed on the verification of the approach towards a target in low earth orbit, precise position and attitude matching, depending on the baselined ADR scenarios, the GNC functions for safe capturing, and the control of the coupled system during de-orbitation.
