The steps needed to define a successful space science mission are numerous. The science drivers, the unique advantages this mission provides over past missions or earth-based experiments, and the payload that it includes are the key factors to guarantee its success. Finding the required information on such topics is not so straightforward, especially as they are usually outside the scope of undergraduate courses. The 2003 Canary Islands Winter School of Astrophysics aimed at providing a focused framework that helps fill this need. Space agencies follow a necessarily complex path towards the selection of a specific mission, as required by the enormous costs that are associated with space. | PAYLOAD AND MISSION DEFINITION IN SPACE SCIENCES This book is intended for scientists and engineers involved in the definition and development of space science missions. The processes that such missions follow from the proposal to a space agency to a successful mission completion are numerous. The rationale behind approval of a mission its definition and the payload that it will include are topics that cannot be presented in undergraduate courses. This book contains contributions from experts who are involved in today s space missions at various levels. Chapters cover mission phases and implementation launchers and cruise strategies including gravity-assist manoeuvers and different thrust scenarios. The payload needed for remote sensing of the Universe at various wavelengths and for in situ measurements is described in detail and particular attention is paid to the most recent planetary landers. Whilst the book concentrates on the ESA Program Cosmic Visions its content is relevant to space science missions at all space agencies. PAYLOAD AND MISSION DEFINITION IN SPACE SCIENCES V.
