A dozen inventors have received a chance to demonstrate the potential for their pet space projects as winners of NASA's 2013 Innovative Advanced Concepts Program Phase I awards. The award winners were chosen based on their potential to transform future aerospace missions by enabling either breakthroughs in aerospace capabilities or entirely new missions. Read on for a closer look at some of the most promising proposals with a view to how they would work, and where the tricky bits might be hiding.
