The two dummies inside -- a 105-pound woman and a 220-pound man -- will help them analyze how landing in the Pacific Ocean after coming back home from Mars or another deep space mission affects the human body. They could then make adjustments and take precautions to prevent astronauts from getting injured during landing based on their findings. These nine tests are meant to assess what the capsule could go through on its way down (while attached to a parachute) in different scenarios. That's why NASA plans to simulate different wind conditions and even wave heights in the future.
