A high-energy sample return Earth re-entry demonstrator to address planetary protection issues
چکیده انگلیسی
For many of the proposed planetary exploration missions, robotically collected sample materials must be returned to the Earth for more detailed analysis. For the more interesting locations in the solar system, full planetary protection guidelines must be taken into account to prevent cross contamination. So far, few missions have demonstrated re-entry from interplanetary space, which requires a considerably greater velocity change than the more common Earth orbit re-entry missions, and so far none have dealt with the planetary protection issues. Missions such as the proposed Mars Sample Return mission must depend on reliable systems to carry out a sample return. Such a complex safety critical system can of course not be used for the first time on a real mission, nor can it be tested under Earth laboratory conditions. This paper proposes a design concept for an European Space Agency testbed to help validate the necessary technology. The spacecraft will carry scientific instruments to help characterise the environment, so that subsequent missions can rely on this.
