The scope of the present document is to describe the Front Door Mechanism of Wide Angle Camera and Narrow Angle Camera of the OSIRS payload and to demonstrate the safety of the mechanism itself. To match the scientific goals it has to prevent the contamination of the telescopes during ground and in -flight operations.

Abstract

The scope of the present document is to describe the Front Door Mechanism of Wide Angle Camera and Narrow Angle Camera of the OSIRS payload and to demonstrate the safety of the mechanism itself. To match the scientific goals it has to prevent the contamination of the telescopes during ground and in -flight operations. Moreover for the in-flight calibration the door itself will be used for the flat field of the cameras. The original design has been carried out according to optimisation techniques and successfully tested during the qualification and acceptance campaign. The results obtained demonstrated that the mechanism is fully compliant to the interface specifications and its performances are not affected by the environmental stresses and by the overall life cycling
