ABSTRACT/RESUME To have a paper included in the Conference Proceedings, the author must prepare and send a camera-ready copy of the paper to the Editor (address see below). However, you may also submit it at the time of the Conference. The Proceedings will be available as a book. The principal author will receive a copy of the proceedings free of charge. The following are some instructions for preparing the camera-ready copy in accordance with the European Space Agency's standards for conference proceedings. Each submission should resemble these instruction sheets in format and style when completed. Start with a concise Abstract/Résumé (limited to 15 lines or 150 words) which summarises the contents of the paper.   1. GENERAL SPECIFICATIONS The paper can be written in either of the two official ESA languages: English or French. The paper must be written in double-column format. As a guideline, the number of pages should not exceed: Invited Paper 12 pages Contributed Paper 8 pages Poster Paper 6 pages 2.

TITLE and AUTHOR AFFILIATION The paper title, author(s) name(s), affiliation, complete mailing address and email should be centred at the top of the first page using the fonts and type sizes indicated above. If there are several authors, the complete affiliation should be given for each of them using superscripts(1) in the authors(2) list(3) to refer to them.   4. HEADINGS This sheet has been typeset in accordance with the style to be followed for the headings. Use the decimal system in Arabic figures for the numbering of headings, subheadings. Major (or section) headings are to be in capitals without underlining. 4.1 Subheadings  Subheadings or subsection headings are to be in lower case with initial capitals. They should be flush with the left-hand margin, on a separate line.

5. EQUATIONS Equations are to be numbered consecutively throughout the paper. Each equation number must be unique (do not use "Equation 2bis" or "4'…"). Equations should be centred, with the equation number in parentheses, flush with the right-hand margin of the column. Leave a double line space before and after equations. Always refer to equations by number, as Eq. 1 or Eqs. 3-6, not as "above" or "below". (1)   6. FIGURES AND TABLES Responsibility for the provision of high quality figures/illustrations resides with the author. They should have the right size for the space they will occupy in the paper, as the Editor cannot provide reduction services. Figure captions should be below the figures; table captions should be above the tables. Use the abbreviation "Fig.1," even at the beginning of a sentence.   Fig. 1. Space Debris   7. ABBREVIATION AND ACRONYMS Define abbreviations and acronyms the first time they are used in the text, even after they have been defined in the abstract. Do not use abbreviations in the title unless they are unavoidable.   8. PAGE NUMBERING In the bottom right-hand corner of each page, write lightly in pencil your last name and the page number. Do not number the electronic paper.   9. REFERENCES Number citations consecutively in square brackets [1]. Refer simply to the reference number, as in [3]. Do not use "Ref. [3]" or "reference [3]"except at the beginning of a sentence: "Reference [3] was the first...." The title of the book or of the journal shall be in italic script. 9.1 Sample References 1. Johnson N.
