Objectives: This activity will build a configurable Test Bed to validate Failure Detection Isolation and Recovery (FDIR) concepts and implementations for spacecraft Avionics data systems. As an important result of this activity a report containing recommendations and suggestion in advance of an ECSS standard for a correct design and implementation of FDIR concepts (for the part that affects the Avionics Data system). Description: Starting from the already available Reference Architecture System Testbed for Avionics (RASTA) system and pushed by recent anomaly events, the aim is to have a real HW test-bed where the conceived or implemented FDIR concepts can be validated. The currently available RASTA system has to be upgraded mainly in order to: - implement redundancies (needed to test FDIR concepts); - improve its configurability/functionality features. At the same time the opportunity will be taken to take account of the latest processor modules (e.g. LEON 3, SCOC?). The upgrade will also provide the reference platform for all applicable building block activities. Reconfiguration Mechanisms, correct use of Safe Guard Memory, fault coverage, BIT are only some of the topics that the availability of a real Test Bed can allow to investigate and validate.

CubeSat nanosatellites may serve to develop, demonstrate and operationally validate some active debris removal technologies at low cost before they are used on larger operational missions to remove defunct spacecraft and upper stages. Critical technologies to be developed include GNC sensors, actuators and software for rendezvous and close proximity operations, debris capture mechanisms, and propulsion or other devices for de-tumbling and de-orbiting. This activity covers the evaluation and trade-off of technologies relevant to Active Debris Removal to be later developed in miniaturised form in a follow-on activity and intended to be finally demonstrated in Low Earth Orbit on a CubeSat nano-satellite mission.

This activity aims at developing theoretical and experimental knowledge on throw-nets for grasping orbital debris. The intended final result is a validated model of how a net behaves in the capture operation, accounting for all theon orbit environmental and system design parameters. This activity shall: 1) Elaborate detailed system requirements for the net system. Starting from a list of userrequirements provided by the Agency, the activity shall produce a complete set of requirements specifying the net system and the validation to be performed. 2) Develop a mathematical model of the net and the interdependence of the various system design parameters(e.g. cable dynamic parameters, knot type, mesh size, size of flying masses, closing mechanism), and on orbit environmental parameters (e.g. distance of throw, speed of throw). 3) Realise a parametric simulator of the capture operation. 4) Identify and experimentally characterise materials and assembly technology for the net. 5) Design a parabolic flight test campaign, related test equipment and measurement instrumentation/techniques. The campaign shall envisage different test items/test so that all parameters can be investigated with at least 2 data points. 6) Procure/manufacture integrate and validate test equipment on ground. 7) Perform the test with a representative sample of net and launcher specimens to cover the principal design parameters and validate the mathematical model. 8) Perform a mathematically rigorous validation of the model against the test results.

The contract will tackle an important item missing from the ESA's current software model for its space science missions, namely thelong-term preservation of scientific data analysis software. Once a project has finished and its specialist operational and softwareengineering personnel have dispersed, new technologies can enable long-term preservation of the data analysis software as computeroperating systems evolve. The work is an initial study that will entail four steps: first, cast the data analysis software of two current and two historical ESA missions into Virtual Machines (VMs); second, prototype tools to perform data analysis in VMs for standard and expert users; third, benchmark VM performance in different computing environments; and fourth, assess the prospects of a general solution for the long-term preservation of data analysis software for all ESA space science missions.

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
-Phase 5: Review of the manufacturing processes implementing anycorrective actions come from the previous phase, second issue of PID and second run in foundry
-Phase 6: Definition of the electrical and thermal resistance/impedance characterization, reliability assessment and radiation test program. For the overall test program the sample size should be at least 100 devices.
-Phase 7: critical analysis of test results. Reliability analysis and identification of future activities needed to qualification of the device, analysis of manufacturing cost and forecast of yield.

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.
