In this joint project of the MIT Department of Aeronautics and Astronautics and the MIT Office of Educational Innovation and Technology, researchers collaborated with visual artists to create three-dimensional visualizations of astronaut motion in microgravity. Through the graphical user interface, which is implemented in X3D, students can interactively explore how astronauts rotate in a microgravity environment without using any external torques, i.e. without contact from the surroundings. These rotations are simulated with results from recent research in astronautics [Stirling, Ph.D. thesis, 2008] using mathematical algorithms that implement core curriculum concepts, such as conservation of linear and angular momentum. The computer character, which was modeled and texture-mapped in Maya®, wears a next generation astronaut space suit which MIT researchers develop for NASA.
