NASA has revealed its newest range of next-generation spacesuits, the Z-2. The Z series of spacesuits is a series of prototypes that NASA is working its way through, with the eventual goal of creating a suit that will be used during future space walks, deep space missions, and planetary EVAs (i.e. walking on Mars). In 2012 it was the Z-1, which bore more than a passing resemblance to Toy Story's Buzz Lightyear (pictured below) -- and now we have three Z-2 designs that are, in a word, otherworldly.
