NASA teamed up with six companies to develop deep space vehicles as part of its NextSTEP program last year. Boeing, one of the six, has now given us an idea of what its creations could look like. The company has revealed concept images of its deep space habitat and transport vehicle that could make it possible to send humans to Mars from a lunar base. Pictured above is the Deep Space Gateway, the habitat Boeing wants to send to cislunar space. It could house critical research for human exploration and could dock other vehicles using a system similar to the International Space Station's.
