Are you a college student? Want to be a part of NASA's mission to send astronauts to Mars? Well, you're in luck. The space agency has announced the Breakthrough, Innovative, and Game-changing (BIG) Idea Challenge that aims to get design help from university students. The challenge is to create a solution for slowing NASA's massive payload with inflatable spacecraft heat shields or hypersonic inflatable aerodynamic decelerator (HIAD) technology. While NASA managed to successfully land the Curiosity rover on Mars, a spacecraft with a crew on board would weigh between 15-30 tons -- slightly heavier than the rover's one-ton load. Couple that weight with the planet's thin atmosphere and you can understand why NASA needs to develop a new system to slow the vehicle's approach. What's more, NASA hopes that the HIAD tech could be used on other missions, too.
