The Pegasus Mission

In the latter part of the 21st century, a probe is sent to investigate the source of radiation recorded by Voyager 1 decades earlier at the very fringes of the sun's influence. The probe discovers a strange object, assumed to be artificial, entering the solar system on a course trajectory for the inner solar system. Earth has assembled a manned mission, utilizing parts left over from NASA's long-retired Space Shuttle program, to intercept the object before it intersects the orbital path of Saturn. During the journey, the ship is lost, but little do the members of the five-person crew realize that they have not seen the last of the space shuttle Pegasus. Nor do they realize just how much their adventure will change the course of humanity. More at http://www.daveconklin.net/
