17th SPINE Meeting – Computational tools for electrostatic cleanliness and space instrument accommodation analysis – 17-19 January 2011, Uppsala University, Uppsala Sweden
Computational tools for electrostatic cleanliness and space instrument accommodation analysis: Workshop and call for inputs
SPIS, the Spacecraft-Plasma Interactions System, is an open source software for spacecraft-plasma interaction simulations, developed and maintained by the Spacecraft Plasma Interaction Network (SPINE) and freely available at www.spis.org. In recent years, SPIS has been used for simulation of particles and field instruments on spacecraft, e.g. to meet the scientific needs for increased accuracy of measurements of low-energy ions and electrons and electric fields. This use is expected to increase as new space missions are upcoming or proposed, for example Bepi Colombo, Solar Orbiter and the Jupiter Ganymede Orbiter. To help in this process, ESA is funding an upgrade of SPIS to meet such needs by 2012. Community input is essential to ensure that the upgrade will concentrate on the features most needed. You are therefore invited to:
- Contribute to the inputs for the SPIS development by stating your needs, ideas and wishes
- Participate in a SPINE workshop on these matters
Talks, Data and presentations of meeting
The requirements for the coming SPIS upgrade based on user community inputs will be discussed at a SPINE meeting hosted by the Swedish Institute of Space Physics on the premises of Uppsala University, in Uppsala, Sweden, 17-19 January 2011 (conveniently close to Stockholm Arlanda airport, see details on web page below). The first part of the meeting will cover presentations of the cosmic vision missions, presentation of the SPIS software capability and of some key applications to scientific observations. The second part of the meeting will include presentations from the scientific community and discussion of the requirements. Meeting details are available at http://dev.spis.org/projects/spine/home/meeting/mxvii
Invitation and call for contribution
Research groups intending, proposing or designing plasma and field instruments for future European space missions or involved in data interpretation are hereby invited to submit their inputs, and to attend the SPINE workshop for discussions on the SPIS upgrade.
Key topics to be addressed include:
- What problems related to spacecraft, plasma and electrostatic environment are expected for future European missions?
- What simulations will be needed?
- What capabilities and performance of simulation tools will be needed?

The detailed agenda will be communicated later based on proposed contributions from participants.
Please forward this announcement to any person you think might be interested.
- 10 Dec 2010: Please indicate your interest to participate in this process and in the meeting
- 7 Jan 2011: Input and meeting presentation submission, meeting registration
- 17-19 Jan 2011: Meeting of the Spacecraft-Plasma Interactions Network in Europe (SPINE), in Uppsala, Sweden. The meeting will start at 13:00 in Monday, Jan 17, and end at noon on Wednesday, Jan 19.
Uppsala, Sweden. The meeting will be held in Museum Gustavianum, the old main building of Uppsala University, right opposite the main entrance to Uppsala Cathedral. See https://www.gustavianum.uu.se/?languageId=1
All hotels in the city centre are within walking distance. Closest (and very nice) are:
- Hotell Villa Anna: http://www.villaanna.se/english/
- Akademihotellet: http://www.akademihotellet.se/index.php?lang=en_UK
- General tourism page information:
Stockholm-Arlanda airport is 18 minutes by train from Uppsala. Trains normally run every 30 minutes. Taxi Arlanda-Uppsala costs SEK 450-460 SEK (around EUR 50) with the two main local taxi companies (be sure to get a fixed price!). The city centre is small, and the meeting as well as most hotels are within 15 minutes walk from the station. Renting a car is therefore not recommended, as you will hardly need it but will have to spend time and money parking it.
Participation in the meeting is free of charge.

16th SPINE Meeting
This meeting will be mainly targeted to the identification of requirements for new R&D activities in the area of spacecraft plasma interactions.
The first half day will be devoted to the presentation of new results as well as ideas and concepts and current plans of Agencies and industry R&D activities. The second half day will be a round table to exchange ideas on the requirements for new R&D activities.
Participation to the meeting is free of charge and open to all organisations from ESA member states but require by sending an email to: Alain Hilgers at esa dot int .
16th SPINE Meeting 23 March 2010 Room B0154, ESA HQ, 8-10 rue Mario Nikis, 75015 Paris, France
15th SPINE Meeting on the 28th and 29th of September 2009 at ONERA, Toulouse, France.
Particular themes are:
- SPIS developments and validation
- Plasma instruments and in-flight demonstrations.
There are, in various stages of execution and planning, various studies that use and update the SPIS simulation software. This is extending the capability of the code and it is important that the community is kept informed of these changes. At the same time, the validation of the code is becoming more critical as the range of applications increases.
Plasma instruments are being flown and are planned for a number of scientific missions, including Cosmic Vision candidates. In addition, ESA’s SSA (Space Situational Awareness)programme includes the definition of plasma instruments for future Space Weather Monitoring. Such monitors need to consume few spacecraft resources but be well qualified. Novel space plasma technologies for generation of thrust and/or power, such as tethers, are also at the stage where in-flight testing is required. Hence there is a need to consider possible flight opportunities for instrument testing and technology demonstration.
14th SPINE Meeting to prepare modelling capabilities in support of plasma instruments for Cosmic Vision
Spacecraft plasma interactions (especially spacecraft charging and contamination by secondary particles) can strongly perturb plasma and particle measurements in space. Therefore, modelling these interaction is important for optimising the design of plasma instruments and their location on the platform and for the scientific exploitation of the data because .
Cross-scale, Laplace, Tandem and other Cosmic Vision missions are planned to include plasma payloads to investigate the magnetospheres of Earth, Jupiter and Saturn and other solar system plasmas. Electrostatic cleanliness of such scientific spacecraft for correct functioning of plasma measuring payloads requires limiting electrostatic potential perturbations and interference from spacecraft-generated charged particles (e.g. secondary/photo electrons and sputtered ions). This leads to a requirement for low spacecraft potential (typically ~1V), well below the energy of particles being detected, and for spacecraft-induced fluxes well below ambient levels. Control and mitigation of spacecraft perturbation of plasma/field sensors is possible through charge alleviation devices, grounding, material selection and siting of detectors.
The European Space Agency has sponsored modelling activities to address these issues. The open source spacecraft-plasma interaction simulation tool, SPIS, might currently lack the required accuracy. Increasing the accuracy to the required level requires significant physics, algorithm and software developments, possibly including better modelling of secondary/photo/sputter emission, better shadowing, control of convergence, optimisation of number of particles per cell and improved trajectory accuracy. SPIS simulation toolkit has been conceived with a modular approach such that extension of the capabilities and functionalities can be performed without reengineering the whole software.r
The meeting will take place on 13-14 November in Room Na213 at ESTEC, Noordwijk, The Netherlands.
Participation to the meeting is free of charge.
