The first Martians are going to have a long ride to red planet, and NASA isn’t quite sure what they’ll ride in. The cramped Orion capsule will have to dock with a larger habitat that provides room for astronauts to live, sleep, work, and exercise. That habitat’s design is still TBD at this point.
To help figure out the best layout for long-term human spaceflight, a company called Draper is developing a way to monitor every aspect of how astronauts use the International Space Station. The idea is to track the astronauts as they move around in microgravity, to learn how much space each person needs to exercise, perform maintenance tasks, and more.
