Outcome of flight operations / failure analysis Soil Sample Outside protrusions did not let the initial idea accommodate Navigation The use of accelerometers could have helped to know and correct positions. Instead of a propelled thrust, a compressed air or propulsion system could work better since it may be east to locate.
