Unfortunately, this doesn't mean we'll see three fancy Z-2 variants in the future. NASA plans to use only one design -- and it's giving the public the power to choose which one it is. Each concept draws inspiration from different sources, including nature and everyday life. For instance, the one called Biomimicry (pictured above) has lights that replicate the bioluminescence of deep-sea creatures and a body that's reminiscent of fish and reptile scales. "Technology" updates NASA's iconic spacesuit with electroluminescent wires and patches, while "Trends in Society" was inspired by sportswear and wearables. People can cast their votes until April 15, after which NASA will build the Z-2 with the winning outer shell. We could see the finished suit as soon as November 2014, but it still has a ways to go before it's ready -- NASA's other suit (the CSSS) will likely make it to space first.
