There is commercial soil available that mimics the conditions of martian soil fairly well. Gravity can be emulated by hanging the device from a spring (which you can optionally adjust to always take X newtons of force via a computer controller). Atmosphere and weathering can be simulated in a vacuum chamber. All those things can be put into a vacuum chamber to simulate low pressure. This is how NASA is developing their drone for the upcoming missions that will fly on mars and other celestial bodies.
