From Popular Science: When it’s done, the concept for a ship that’ll take astronauts to deep space won’t look like much. Actually, it kind of sounds like a mess: the “Deep Space Habitat” is being cobbled together from scrap parts of the International Space Station, and even a museum mockup. Obviously, it’s not going to send anyone to deep space. But it does give us a tantalizing look at what it’ll look when NASA does take the next steps in space travel.
