When NASA announced the completion of the Space Launch System's critical design review Oct. 22, it also released an updated illustration of the rocket, with the core stage now orange instead of white. NASA said in a press release that orange is "the natural color of the insulation that will cover those elements," as was the case with the shuttle's external tank. Not explained in the release, those, are the curved gray and orange stripes on the solid rocket boosters. Some think they are intended to evoke memories of the shuttle itself or the logo of original shuttle contractor Rockwell International — or, perhaps, computer game company Atari. Credit: NASA
