NASA is hard at work on designing the perfect aircraft to land on Mars. Just a couple of weeks ago, the space administration showed a new wing shape it is testing for future Red Planet-bound planes. As part of furthering these developments, NASA recently brought on a few students to help with its Preliminary Research Aerodynamic Design to Land on Mars program, otherwise known as Prandtl-m aircraft. The participants built a boomerang-shaped plane made of carbon fiber, which was then tested in an aircraft hangar and a different set of higher altitudes outdoors. Unfortunately, NASA says test flights didn't turn out as expected every time, namely due to the complexity of having an adequate launch system in place. One option, for example, was to have a radio-controlled plane that would take the research aircraft to the necessary altitude and have it be released.
