16th SPINE meeting

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

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

14th SPINE Meeting to prepare modelling capabilities in support of plasma instruments for Cosmic Vision

Access to presentations


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.

  • spacecraft plasma interactions effects on scientific instruments
  • onboard calibration of plasma instruments
  • modelling requirements for plasma instruments
