Design compromises of multi-function tools for both in-situ detection and particle return from asteroid Original Research Article

The need to avoid tool changes for weight constrains and high reliability of planetary sampling tools onboard of lander modules requires many contradictions in design formulation. The suggested perceived modeling method is used in this paper to analyse the fine balance to be made in the design compromises of sampling mechanism. A systematic study was presented by showing the proposed sampling tool for the Mars Express rover to illustrate the compromises to be made for high reliability in a hostile environment.
