This is how NASA envisions the first deep space exploration spaceship. It is called Nautilus-X, and it stands for "Non-Atmospheric Univeral Transport Intended for Lengthy United States X-ploration". WOW! This spaceship can carry up to 6 people in deep space, for one month up to two years! It's got an integrated centrifuge to provide artificial gravity, and the habitation modules are mostly inflatable. In some configurations, Nautilus-X comes with little baby spaceships and landers, and it can dock with the ISS. Oh yes, and it is cheap too... Only $3.7 billion and 64 months to build.
