Abstract :
[en] This paper analyses recently launched or planned to launch mission contamination budgets and preventive measures, regarding to their sensitivity. Contamination effects are reviewed on the basis of instrument type, wavelength range and performance requirements. Preliminary guidelines are then drawn up for budgeting contamination. In parallel, some suggestions are proposed to reasonably improve or relax cleanliness requirements without degrading a mission. The costs of cleanliness control are examined. It leads to investigate future activities needed for making the guidelines easily understandable and routinely applicable for more effective contamination control and optimized cleanliness cost.
