Spacecraft Plasma Interaction Guidelines and Handbook

This handbook provides comprehensive guidelines on spacecraft plasma interactions, emphasizing the importance of characterizing materials and understanding the effects of plasma-induced hazards. It aims to consolidate pertinent literature, requirements, and simulation resources while promoting cooperation in Europe. Key features include an interactive PDF version with clickable elements, tables of contents, and links to relevant tools and testing facilities. The document is essential for space mission designers and engineers to navigate the complexities of plasma charging and ensure spacecraft safety and efficacy in various environments.

  2. Guidelines and Handbook - Overview • Background & aims • Table of Contents • Publishing Scenario • Architecture • Demo

  3. ESA’s co-ordinated Spacecraft Plasma Interaction activities European Co-operation on Space Standardisation SPIS ECSS SPINE Spacecraft plasma interaction simulation Spacecraft plasma interaction network in Europe Guidelines Materials characterisation Spacecraft plasma interaction guidelines and handbook

  4. Guidelines and Handbook - background • Arose from the ECSS Spacecraft charging standard • Formal standards are legal documents • There are other de-facto standards (e.g. NASA handbooks) • There are many important effects that do not lead to requirements • As well as requirements, there is a need for guidance • on how to avoid plasma-induced hazards. • what the requirements mean in common situations • what codes are available • what test facilities there are

  5. Guidelines and Handbook - aims • To bring together, from open literature • guidelines and requirements • equations • data • tabular information and graphs • To promote the use and sharing of resources in Europe. • Links to simulation resources • Links to testing facilities • Hardcopy and interactive versions • QinetiQ and BIRA/IASB

  6. Introduction General plasma parameters Sheath and Wakes Guidelines Active electrostatic systems: (Tethers and electric propulsion) Surface Charging Guidelines Internal Charging Guidelines Solar Array Guidelines Guidelines and Handbook - TOC • Each chapter contains • Effects • Guidelines & requirements • Tools and equations, including graphical examples • Simulation and test procedures (and URLs)
