Lunar Lander Project Patrick Thurston and David Cobler

Problem VTC is sending a cube-sat to the moon and the Lander needs to be thoroughly tested before a final design can be made.

Mission Diagram

Solution Create a testing system that will repeatadly test the lander under various conditions and record the information gathered.

Technical Details The testing platform will need to simulate: – Varying drop height/mass/velocity – Varying Landing orientations – Varying Terrain conditions – Calculate the shock – Calculate the stability of the lander
