Astronauts in the ISS usually suffer mild bone density reduction and loss of muscle mass. On a mission to Mars where astronauts would experience much less gravity and an extended time period, the effects could be greatly amplified. My entry, the BMDD device (Bone and Muscle Deterioration Detection Device), is an attempt to measure the effects of this deterioration over time, and under different circumstances. The device operates similarly to a joint brace, with sensors on the sides of it. The sensor on the right is infrared, meaning it doesn't detect deterioration past the tissue level. The left one is an x-ray scanner that accurately senses losses in bone density. The STL file is simply the framework for the device, as it would need extra installments such as batteries and computing elements. If properly utilized, this technology could permanently influence space travel and it's negative biological effects on humans.
