General Discussion

 

ABSTRACTS

PC Version of the ESABASE/Debris Analysis Tool

A.Langwost, H.Sdunnus, D.Gunia, S.Hauptmann (eta_max, Braunschweig)

 

Similar to other space disciplines, the current European tools for space environment and thermal analysis are ageing. The development of tools like ESABASE started during the Eighties or early Nineties and core applications and modules remained unchanged since then. Efforts made in the meantime concentrated in the maintenance and extension of the scientific kernel of the application, rather than on the framework. In the current situation there are tools featuring state-of-the-art environment modelling capabilities coupled with outdated programming methods and data structures and almost archaic front- and back ends. ESABASE is one of the tools affected by this situation. ESABASE enables the user to construct an articulated analysis model and to perform a variety of space-specific analyses (like debris, atomic oxygen, radiation) on the model along its orbital trajectory. In view of the actual situation, ESA took the initiative to port the Debris application of ESABASE to Linux and Windows PC platforms. This paper provides an insight to ESABASE2 – the result of this activity. ESABASE2 is composed of an up-to-date framework based on Open Source components like the Eclipse Graphical User Inter-face or the OpenCascade CAD library, and the previously existing well established debris models like MASTER. This paper introduces the capabilities of the ESABASE2 framework together with the debris application. It will demonstrate the modern user interface as well a new ray tracing algorithm and the integration of the ORDEM2000 debris model.

Assessment of In-situ Impace Detectors

Karl Dietrich Bunte, Neil McBride

 

The main task of the “Assessment of In-situ Impact Detectors” study was the development of two breadboard models of the impact stage of advanced particle detector concepts. Several existing detection principles as well as suggestions for new approaches were reviewed in detail to find out the most suitable methods. Breadboard models based on a combined PVDF/PZT sensor (Holmes) and of a calorimetric impact detector (AIDA-cal) were designed and manufactured. Functional, sensitivity, calibration and environmental tests were performed to gain sufficient information for the evaluation of the detection methods. In a future development step it is foreseen to combine the impact stage with a first sensor stage which enables the full detector to determine the mass, the velocity and the trajectory of the impacting particle.

Processing, Analysis and Interpretation of Data from Impact Detectors

Karl Dietrich Bunte, Neil McBride

 

A variety of quite different tasks were performed in the “Processing, Analysis and Interpretation of Data from Impact Detectors” study comprising the development of a database for European in-situ impact detector data (EDID), the DEBIE-1 operation and data acquisition, and the DEBIE-2 implementation support in part A of the project. Part B was dedicated to analysis, testing and modelling activities: GORID data analysis, DEBIE-1 data analysis supported by additional calibration tests, upgrade of the DIADEM tool for debris cloud flux and debris/meteoroid background flux analysis. The work performed will be summarized and the findings of the study will be outlined.

Impact Test Results Database

F. Schäfer (Ernst-Mach-Institut, Freiburg) & K. Ruhl (eta_max, Braunschweig)

 

There is an expressed interest of European Industry and Space Agencies to have web-based access to experimental results from hypervelocity impact tests on various spacecraft surfaces, structural elements and shielding systems to allow making the proper selection for spacecraft protection systems based on impact test data. To this purpose, a server-based, platform-independent Impact Test Results Database has been designed and is currently being filled with data from European sources. The presentation provides a summary of the datasets that are currently contained in the database, gives an overview of the underlying software and concludes with an on-line demonstration of the database.

Ongoing and Planned Activities in the Field of In-situ Impacts

G. Drolshagen (ESA/TEC-EES)

 

An overview is given of ongoing and planned ESA activities in the field of in-situ impacts from meteoroids and space debris. Specifically the following points are addressed:  analysis of retrieved hardware; realized flights of in-situ detectors in Earth orbit;   development of passive collector cells;   development of active in-situ detectors;   flight opportunities;   modelling and simulation tools;   study of impact effects;  coordination and cooperation activities;  related funding situation at ESA.

Dose Estimation by Simulation of the ISS Radiation Environment

C. Fuglesang (ESA Astronaut Centre, Köln)

 

The aim of the DESIRE (Dose Estimation by Simulation of the ISS Radiation Environment) project is to calculate the radiation levels inside the Columbus module of the International Space Station, and from these estimate the doses received by astronauts and equipment. Following radiation physics validation work and implementation of the Columbus and ISS geometries in the GEANT4 particle transport toolkit, the transport of incident particles through the walls of the ISS has been simulated. The flux of incident particles has been estimated for the ISS orbit with the ESA SPENVIS package, with the CREME96 cosmic ray code, and with other models. In this presentation, a summary of the DESIRE project main outcomes is given.

Plasma Laboratory in Space

Univ. of Bari

 

The European Space Agency has initiated, in the context of the General Studies Programme, a study of the possible use of space for studies in pure and applied plasma physics, in areas not traditionally covered by “space plasma physics” or current space facilities such as the International Space Station. A team of experts has been set-up to review the possible experiments that could be undertaken and the plasma phenomena they may address. As broad a view as possible has been taken to address fundamental research and potential applications in plasma physics in all plasma physics domains. Key results of this study including a list of highest priority experimental concepts, and a more detailed proposal of mission scenarios to perform a set of experiments on medium scale (i.e., of the order of 100 m to 1 km) on both magnetized and non-magnetized plasma ranging from collisional to collisionless regime.

Spacecraft Plasma Interaction System

ONERA and Artenum

 

In less than three years ONERA/DESP together with Artenum has developed complete spacecraft plasma simulation software under contract with ESA through the Technology Research Programme. The code is mainly Java and Jython based and is now freely available in open source. While the development and the testing of the software were under the responsibility of the contractor the practical validation on test cases was done by the SPINE community. From this innovative approach, results a widely available and well tested tool which has already been used at ESA, CNES and ONERA for modelling activities of spacecraft-plasma interactions phenomena to support SMART-1, Cluster and Microscope. This presentation gives a review of the code concept, functionalities and applications.

Spacecraft Charging and Plasma Interaction Guidelines

QinetiQ and BIRA

 

Guidelines for spacecraft projects that addresses the need of the space research and space industry communities for the assessment of problems related to spacecraft plasma interactions have been developed by QinetiQ together with BIRA in the context of the Technological Research Programme in collaboration with the SPINE community. It also promotes the use and the sharing of European resources, especially regarding knowledge and expertise for spacecraft design and operations and test facilities. The guidelines consist of two items: a hardcopy version including text and graphs of the guidelines and a public interactive version that shall include simple formula computational capabilities and list of assets and contact points for support and access to facilities and expertise. This representation reviews the guidelines features and functionalities.

Ongoing and Planned Activities in the Plasma Domain and Other Issues

A. Hilgers (ESA/TEC-EES)

 

The recent ESA R&D activities in the domain of spacecraft plasma interactions have been based on a careful review of the requirements of the interested parties (European industries, academia and space agencies). This has been performed through an informal network of experts set-up in 1999 (SPINE, cf www.spis.org/spine). Besides identifying the community requirements, SPINE has also ensured so far the exchange and cross-validation of practices and tools. Thanks to such collaborations the European spacecraft plasma interaction community has moved in less than 6 years from a situation in which tools and standards were essentially non-European to a situation today in which European tools and standards have been developed and are in a process of consolidation and international recognition. In this brief presentation the recent initiatives and achievements are reviewed and future perspectives are outlined.

The SWENET Software Infrastructure

P. Beltrami Karlezi, K. Ruhl (eta_max space GmbH)

 

In the frame of the ESA’s Space Weather Pilot Project, eta_max space and BIRA have de-veloped a dedicated software infrastructure for the Space Weather European Network (SWENET). This infrastructure works as a web portal providing structured and user friendly access to the data and services developed in the various pilot project activities. It also pro-vides data of interest to the space weather community, collecting it from various external sources and making it available through a common database. Users can search, download and plot data from specific time periods and combine different sources, providing a powerful analysis tool. Daily reports, alerts and data sets can also be received by email through an automatic service. This presentation provides an overview of the capabilities of the SWENET infrastructure highlighting the most important services and functions.

The Space Weather Applications Pilot Project Cost Benefit Study Overview

T.I. Woodward (Systems Engineering & Assessment)

 

ESA has embarked on an initiative to assess the long-term business case for a possible future European space weather service (SWS), as part of the space weather applications pilot project. Studies carried out prior to the start of the pilot project analyzed user requirements and mission needs for a European SW service segment.  During the pilot project, a network of space weather services has been established to provide a sample of realistic economic data on the costs and benefits of SWSs in Europe.  The current paper presents the methodology of the study and early results of the cost benefit assessment.

Using Nanosats for Space Weather Monitoring

M. Hapgood (RAL, UK) S. Eckersley (EADS, UK), R. Lundin (IRF, S) and M. Kluge (EADS, D)

 

This ongoing study is investigating how current and emerging concepts for nanosatellites may be used to monitor space weather conditions. The study initially reviewed requirements and identified five different constellations for such monitoring. In parallel, the study iterated a set of instrument and spacecraft solutions which are currently being subjected to mission analysis to identify critical issues. Finally, the study will review the prospects for a space weather nanosatellite programme. Preliminary conclusions will be discussed here.

Ongoing and Planned Activities in the Space Weather Domain and Other Issues

A. Glover (ESA/TEC-EES)

 

The ESA sponsored Space Weather Applications Pilot Project is now reaching the end of an approximately 2 year development and testing phase.  This pilot project centered on the development of a network of targeted service development activities, SWENET,  supported by a common infrastructure and making use of already existing space weather data sources. An independent cost and benefit assessment of such an approach for coordinated space weather services is ongoing and is expected to conclude in May 2006. Already at this stage, recognizing the usefulness of SWENET as a coordination tool and a platform for demonstration of European know-how in the field, the Space Weather Working Team has initiated a strategy for the SWENET consolidation and its long term development. In parallel, various activities are ongoing to prepare the groundwork for future space based developments aimed at increasing European participation in Space Weather monitoring activities. In this short presentation the recent initiatives and achievements related to SW monitoring and related R and D activities are reviewed and future perspectives in the context of other European initiatives are outlined.

Radiation Environment Research with Multiple Monitors

Sebastien Bourdarie (ONERA DESP, Toulouse)

 

The RERMM (Radiation Environment Research from Multiple Monitors) project aims to produce a tool able to interpolate between heterogeneous measurements of ionizing particles made in space by various European radiation monitors. With this tool, instantaneous maps of the space radiation environment can be produced to enhance and complement predictions of environmental models. A potential application of these maps is be to restore the environment encountered by a satellite with no monitor onboard for anomaly analysis or to deduce the background in detectors; it can also be of help for extravehicular activity planning. Moreover, this study is a first step to derive a new generation of environment models for long term effects, for material degradation, or for drifts in electronics characteristics.

SREM Data Analysis and Applications

H. Evans (ESA/TEC-EES)

 

The ESA Standard Radiation Monitors (SREM) are simple particle detectors developed for spacecraft monitoring applications. Models are currently flying on PROBA-1, INTEGRAL and ROSETTA, providing data on the radiation environment in the magnetosphere and in interplanetary space. The instruments can detect protons with energies in excess of 12 MeV and electrons above 0.75 MeV. A review of analyses performed with the data and its uses for future mission planning purposes is presented.

Launch and Initial In-Orbit Check-Out of the Giove-A MEO Radiation Environment Monitors

C.I. Underwood, B. Taylor (U. Surrey, UK), K.A. Ryden, D.J. Rodgers, C.S. Dyer (QinetiQ, UK)

 

Giove-A, a small (c. 600 kg) satellite built by SSTL (UK) for ESA was successfully launched on 28th December 2005 into a 24,000 km circular, 56 degree inclination orbit. Whilst its primary purpose is to test the critical navigation payload technologies needed for future operational Galileo satellites and to secure the use of the frequencies allocated by the ITU for the Galileo system, its secondary objective is to measure the radiation environment encountered in medium Earth orbit (MEO). It therefore includes radiation environment monitors constructed by the University of Surrey (CEDEX) and QinetiQ (MERLIN). Early results indicate the payloads are working well and that the environment is very dynamic.

In-Flight Experiments and Data Analysis; Ongoing and Planned Activities in the Domain and Other Issues

P. Nieminen (ESA/TEC-EES)

 

In addition to the currently ongoing activities related to radiation monitors and their data analyses, the Agency is planning various other developments in the domain. These include flight of the Standard Radiation Environment Monitor (SREM) on a number of future ESA missions; the design and manufacturing of the high-fidelity Energetic Particle Telescope (EPT); radiation monitor and experiment package proposed for the AlphaSat mission; the General Space Environment Monitor (GSEM) development; the Space Environment Monitor for Telecom missions (SEMTEL); and other experiments. Activities for further analyses of the data that is being continuously accumulated (and that can be expected to increase in volume in future) are being proposed as well. A brief summary of these developments is given.

Accuracy of Engineering Approaches to Radiation Shielding Analysis

R. Lindberg (ESA/TEC-EES)

We compare the Monte Carlo and the sector-shielding approach to obtain dose estimates in spacecraft systems. As of today, the general approach is to add additional margins to that of the results of a TID analysis. This is done to safeguard against possible systematic errors in the analysis. Guidelines for the choice of simulation parameters and physics list for such applications are being established. In this work the Geant4-based GRAS tool and the SSAT coupled with SHIELDOSE-2 were applied on a range of geometries, including a realistic model of the ConeXpress mission, in order to quantify the level of agreement and discuss possible related systematic errors introduced in radiation analyses.
Radiation Effects Analysis Tools –Models and Software (Status)

Fan Lei (QinetiQ)

The REAT-MS (Radiation Effects on Advanced Technologies - Models and Software) project covers various radiation engineering-related developments. These include establishing a simulation framework for GEANT4-based space applications; implementation a GEANT4 microdosimetry analysis tool (GEMAT) with interface to SPENVIS; design iteration and improvements to the widely-used Sector Shielding Analysis Tool (SSAT; validation and comparison of various nuclear-nuclear interaction models in GEANT4 and improvements to the models' performance; development of a simple CAD/Geant4 interface based on the use of tessellated geometry; and development of a prototype for Inverse Monte Carlo method for computing doses. The status of the project is presented, and future developments are outlined.

Overview of Component Related Studies in TEC-QCA 2006

A. Mohammadzadeh (ESA/TEC-QCA)

An overview is given of ongoing activities of the Radiation Effects and Component Analysis Techniques Section. The Activities presented cover R&D activities, Frame Contracts, Radiation Facility support and Flight Instrumentation development. New EEE component technology, increased component complexity and the use of COTS necessitates strong and continued R&D activity in the field in combination with results from in-flight instrumentation. Activities cover assessment of components such as; DDR SDRAMs, SRAMs, Optoelectronics, CCDs, APS, RadFET, Deep Submicron devices, microprocessors, etc. Additionally, development of in-flight instruments such as Radiation Monitors and Component Technology Test Beds is described

Validation of a Geant4-based NIEL calculation tool

Hans-Herbert Fischer and Klaus Thiel, University of Köln

The prototype of a software tool to calculate NIEL and to estimate radiation induced performance degradation of semiconductor devices has been successfully developed. The NIEL calculation part of the simulation tool uses Geant4 physical models and an algorithm for screened Coulomb scattering. The verification and validation test results of the NIEL calculation tool are summarized and suitable steps to convert the prototype into an engineering tool are discussed.

SPace ENVironment Information System (SPENVIS)

D. Heynderickx (BIRA, Belgium)

Over the years, SPENVIS has proven to be a reliable and popular community service for evaluating the space environment and its effects on spacecraft systems. The current status of the system will be reviewed, and the new developments foreseen for the next contractual stage will be outlined, with emphasis on third party developer tools, commercialization and usage statistics.

Radiation Effects Tools: Ongoing and Planned Activities in the Domain and Other Issues

 

G. Santin (ESA/TEC-EES)

The effects to spacecraft due to space environment belong to several domains, while analysis tools, being developed by experts in the different areas, tend to be specific to each application. A coordination of the development efforts is therefore important. SPENVIS is a "de facto" standard for tool integration in a web-based framework. The harmonization of modelling and analysis tools requires the use of coherent interfaces in the treatment of environment, mission and spacecraft parameters. In this context, some ongoing and planned activities will be outlined, including new tools for debris, radiation and plasma effects analyses and exchange protocols (STEP for Space Environment, CAD interfaces, GDML interfaces to and from GEANT4 based tools, etc.)

Application of STEP technology for Space Environment Tools (STEP-SPE)

The project is a cooperative effort between ESA, EADS-Astrium, EPM, eta_max and INCKA. The goal to design and develop a STEP protocol and its associated libraries to exchange data between space environment tools, such as ESABASE, SYSTEMA etc. Based on the developed libraries, EADS-Astrium and eta_max will then develop converters, respectively for SYSTEMA and ESABASE. The current status of the project will be presented.  General STEP technology will be explained (why use STEP, what does it mean, STEP protocols, development process).  Further some conversion examples using ESABASE will be given (ESABASE input and the corresponding data in the future STEP-SPE protocol).

 

Collaborative Platform and Integrated Modelling Environment used by SPINE: Lessons Learned

 

Julien Forest (Artenum, France)

In the frame of the SPINE community, an important effort has been performed to develop a set of consistent open-source tools to support the development of scientific software and the modelling process. Initially, developed in the frame of the SPIS project, SPIS-UI is a generic and multi-physics pre-processing/simulation/post-processing framework. Based on modern technologies (Java, Jython/Python, VTK), SPIS-UI offers in fact a complete Integrated Modelling Environment (IME) design to help and guide the user along the whole modelling process. Developed in an open-source approach, it is used today in several domains of application, outside the strict field of the plasma modelling. Last, SPIS-UI integrates several components, who know their own life and have a very active community dynamics today. To answer to the need of remote scientific and industrial communities like SPINE to have a Common Virtual Laboratory and tools to help a remote software development, a modern collaborative platform, called LibreSource, has been provided. The objectives of LibreSource are to offer in a simple tool a forge of next generation, for the software development, and an advanced Web portal to enhance the groupware of hosted communities and projects. Since the initial hosting of the SPINE, LibreSource became one of the main actors of the collaborative tools in Europe. The development and the use of these tools were very rich of lessons and provide a lot of feedbacks, not only related to the tools themselves but also to the methods of work and leading of community based projects. Extended today to other fields of application, both projects are a good example of research-industry transfer. These results will be presented and discussed in details.

Quantum Mechanics for Space

 

Yannick Bidel (ONERA Châtillon)

The aim of this project  is to provide a roadmap for future European developments in the field of quantum technology applications and verification experiments (excluding quantum communications and quantum computing, which are addressed in other Agency activities); to identify the most promising new venues of research; to outline the possibilities for theory and technology research networking both internal to Europe as well as with external partners; and to propose a preliminary concept for a technology demonstration mission or a test-bed for one or more key quantum applications or experiments chosen. In this presentation, the status of the project is summarized.
