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
