Manned geosynchronous Earth orbit (GEO) servicing study

"An assessment of human/robotic servicing of satellites in Geosynchronous Earth Orbit (GEO), and recommendations of technologies to consider investing in which enable or enhance these operations. The assessment also examined various element/vehicle architectures and the potential benefits of the recommended technologies to future human spaceflight exploration. Areas of investigation included cargo transportation to GEO, crew transportation to/from GEO, long-term human presence considerations in GEO, and the synergy of human and robotic activities in performing a suite of satellite repair, refuel, refurbishment, and relocation missions"--Provided by publisher.
