Further Information:

19th SPINE Meeting

The objective of the Spacecraft Plasma Interactions Network in Europe (SPINE) is to share resources and to co-ordinate efforts in all domains related to the interaction of Spacecraft with the space plasma, including spacecraft charging. It is acting as an advisory body for the ESA Space Environment and Effects Network of Competences. The 19th SPINE meeting is organised in coordination with several Final Presentations related to SPIS modelling framework which is supported by the SPINE community. . This meeting is open free of charge to all interested persons. Issues to be discussed, will include:

  • Possible new ISO standards in the area of spacecraft plasma interactions

and the need for updating of ECSS-E-ST-20-06C standard.

  • ESA’s Technology development plans (GSTP, SSA and others)
  • New results and current issues in the area of spacecraft plasma interactions.

Please inform David.Rodgers@esa.int to register your intention to attend and to propose additional discussion topics and presentations you would like to make.


SPIS-GEO: Simplified MEO/GEO tools for spacecraft charging

The European Space Agency has funded an activity called “Simplified MEO/GEO tools for spacecraft charging”.(SPIS-GEO)

This activity has been performed by an industrial consortium (ONERA, Astrium SAS, OHB-Sweden) led by the Artenum company. The aim of the SPIS-GEO project was to improve and adapt SPIS, a tool for the evaluation of surface electrostatic charging, so that it can be used without specialized training in the context of GEO/MEO applications.

SPIS has already shown its capabilities but required in general a high level of expertise to be fully exploited. The use of SPIS in an industrial context, such as for commercial missions in medium and geosynchronous Earth orbits (MEO/GEO), remained thus difficult and required experts in plasma physics and space environment.

SPIS-GEO addresses these issues with a fully redeveloped and deeply simplified user interface based on industrial standards. SPIS-GEO also includes extended models to handle the most relevant and critical configurations of commercial missions (e.g. eclipse exit transition, rich adaptable material properties).

SPIS-Science: Computational tools for spacecraft electrostatic cleanliness and payload.

The European Space Agency has funded an activity called “Computational tools for spacecraft electrostatic cleanliness and payload” (SPIS-SCIENCE).

The SPIS-SCIENCE project managed by ONERA aims at providing scientists with accurate evaluation of spacecraft plasma interaction effects for science missions with low-energy plasma instruments.

The SPIS (Spacecraft Plasma Interaction System) software has been modified in order to provide, at system level, accurate simulation of plasma interaction with spacecraft and instruments. Main new capabilities consists in: advanced instrumentation (plasma sensors, Langmuir probes, particle detectors), particle trajectory algorithms (Forward/backward, Test Particle method, exact/iterative solvers), simulation scenario (changes in simulation conditions), thin elements (wires, plates, semi-transparent grids), upgrade of boundary conditions, better user machine interfacing (pre/post processing, tabulated material properties).

Applications of the tool to Solar orbiter, Cluster and Cassini will be presented.

AISEPS: Assessment of the Interactions between Spacecraft and Electric Propulsion Systems.

The European Space Agency has funded an activity called “Assessment of the Interactions between Spacecraft and Electric Propulsion Systems” (AISEPS).

The AISEPS project managed by ASTRIUM SAS aims at moving a step forward in the simulation method, both from the accuracy and standardization point of view.

The SPIS (Spacecraft Plasma Interaction System) software has been modified in order to provide, at system level, accurate simulation of EP plume and its interaction with S/C. SPIS is an advanced tool to simulate spacecraft charging. Plume models for the eleven thrusters currently included in the Plume Database have been implemented in SPIS.

Application of the tool to SMART1, SGEO and Bepi-Colombo will be presented.

The 18th SPINE meeting will focus on the following themes:

  • R&D Requirements for Spacecraft Plasma Interactions
  • SPIS improvements and Evolutions

The meeting will also be a chance for people to present and discuss topics that may later be presented at invalid link : 12th Spacecraft Charging Conference(Illegal character in path at index 4: 12th Spacecraft Charging Conference).

1.1) Invitation and call for contribution

You are invited to participate in the 18th workshop in the SPINE series. Attendees are invited to make presentations on their work in the field of spacecraft plasma interactions. Presentations of a general nature are welcome and this is a good opportunity to present work to European colleagues that may later be given at the SCTC in May. In addition, we invite your ideas on two specific themes:

  • ‘R&D Requirements for Spacecraft Plasma Interactions’ to help ESA to define a new Technical Dossier outlining the needs for future tools, testing, experimentation and Methodologies, and ;
  • ‘SPIS improvements and Evolutions’ describing recent changes to SPIS and needs for future evolution.

Please indicate your intention to attend the meeting by and to make a presentation by sending an email to: David.Rodgers at esa.int preferably before 20 February 2012.

Attendees data

2) SPIS training: Introduction to SPIS.

2.1) Overview and objectives

In response to the community demand, Onera and Artenum, with the support of ESA, intends to organize a two days SPIS training course.

This course shall provide an introduction to the use of the spacecraft-plasma interaction tool SPIS. Its aim is to make new users autonomous regarding the basic uses of SPIS at the issue of the lecture. In addition, the course will act as a refresher course for more experienced users, to help make them familiar with new updates in the code. A special attention will be done on the basic modelling of a few classic space configurations like GEO and LEO orbits.

This course shall gather both talks and hands on trainings.

The participation to the SPINE meeting itself can be independent on the participation to the training.

2.2) Programme

A preliminary program is already available at the bottom of this page. Its contains may be updated according feedbacks gathered through the collected expressions of interest.

2.3) Expression of interest and cost information

Up to two sessions (of up to 12 students) are intended at ESA/ESTEC, in Netherland, in coordination with the next SPINE meeting (i.e. 2-days course 1, then 1-day SPINE, then 2-days course 2). The planned dates for the training are:

  • 5-6 March 2012: SPIS training course – session 1
  • 8-9 March 2011: SPIS training course – session 2

A participation fee of 1350.00 € VAT excluded by person for the 2 days lecture will be demanded to cover the organization cost, with a possibility of reductions for organizations (i.e. commercial company or academic) wishing to register for the same session more than one person. In this case a sliding scale fee is proposed (reduction of 5% on the fee for the second student, 10% on the third, 15% on the fourth…) in the limit of the maximum number of students by session.

In order to support the SPINE community dynamics, ESA also proposes an “ESA student grant” for a limited number of invited students. Preference will be given to ESA staff, academia and new users.. Please contact ESA for further information by mailing to Mr. David Rodgers (david.rodgers _at_ esa.int).

We remind you that, up to now, the organization of these “Winter school” sessions remains dependent on a minimum quorum of pre-registered students according your expressions of interest.
