Abstract Scope |
Recent advances and interests in space exploration have led to important questions on the effect erosion can play on space vehicles. Those expected to be on Mars long term are exposed to extreme environmental conditions, where the abrasive Martian regolith should be taken into account to consider the erosion and degradation of aerospace materials. By a uniquely in-house designed testing rig with high-velocity regolith impacts to metals and polymers commonly used for spacecrafts, a wind storm on Martian surfaces can be simulated. The impact velocity and the angle of impact will be recorded. The eroded surface will be characterized both qualitatively and quantitatively. These experiments will allow for an understanding of erosion behavior of these materials from Mars Regolith, and create a prediction of how these materials could withstand the environmental conditions of Mars. |
