The DIRECT team produced a 131-page DIRECT v2.0 exploration architecture study that was released on September 19, 2007 at the AIAA "Space 2007" Conference in Long Beach, California. According to the group, this paper was created within a nine-month study. The paper provided detail on how the launch vehicles would be one component of a wider-reaching architecture for enabling the US to maintain the International Space Station (ISS), fly lunar missions, and provide additional capabilities for the NASA human spaceflight program. These capabilities included missions to Mars, Lagrangian point staging architecture options, and mission architectures for visiting Near-Earth object destinations.
