Somewhere deep in the Marshall Space Center, in an unmarked beige hangar, NASA is building a spaceship. A spaceship built with spare parts, scrap hardware from the International Space Stations, a left-over aluminum-lithium cylinder and even museum mockups. One day, it may become the vessel that takes humans to Mars.

NASA engineers lead by Paul Bookout are talking about it at the the Fifth Wernher von Braun Memorial Symposium, happening now in Huntsville, Alabama. Bookout's team is working with a team from the Johnson Space Center in Houston led by astronaut Benjamin Alvin Drew, a USAF Colonel who's been to space twice, including on the last mission of the Space Shuttle Discovery.
