While working on designing an X-ray navigation system for NASA's next- generation Black Hole Imager, Dr. Keith Gendreau, a physicist at the Goddard Space Flight Center, developed the world's first X-ray communication system.
The Black Hole Imager is one of the vision missions that is in the Beyond Einstein Program. Its objective is to resolve the event horizon of a super massive black hole. It will do this by extremely high- angular- resolution x-ray imaging that is better than a tenth of a microarc second - about a million times finer than the Hubble Space Telescope.
