If you are a K-12 student in the United States, your challenge is to create a digital 3D model of an object that could be used by an astronaut to maintain physical health on a 3-year mission to Mars. Your design must be intended to be 3D printed and could be used for a range of medical needs including diagnostic, preventative, first-aid, emergency, surgical, and/or dental purposes. While exercise, psychological, and nutritional health are important, they are not priority areas for this challenge. Retired astronaut Scott Kelly's historic one-year mission on ISS provided insights on how the human body reacts to long duration spaceflight, but the Journey to Mars will take approximately 30 months. What health-related items do you think an astronaut will need on that journey, and why would these items require a 3D printer? It's time to start flexing your problem-solving and design skills to find a solution, good luck!
