  • Future Plans for the Deep Space Network (DSN)
    Future Plans for the Deep Space Network 1 September 1, 2009 Future Plans for the Deep Space Network (DSN) Barry Geldzahler Program Executive, Deep Space Network Space Communications and Navigation Office National Aeronautics and Space Administration (NASA) [email protected] (202) 358-0512 and Les Deutsch Chief Technologist, Manager for Architecture and Strategic Planning Interplanetary Network Directorate Jet Propulsion Laboratory (JPL) California Institute of Technology [email protected] (818) 354-3845 September 1, 2009 Abstract NASA’s Deep Space Network (DSN) is a critical part of every NASA solar system mission, serv- ing as the entity that ties the spacecraft back to Earth and providing data from science instru- ments, information for navigating across the solar system, and valuable radio link science and radar observations. In the future NASA strives to improve dramatically each of these capabili- ties, enabling ever more complex and challenging planetary missions. This white paper explains the plans currently in place for advancing the DSN to serve this future mission set. It also ex- plains what is actually possible if more performance should be desired to enhance the science return of these missions. The DSN will continue to work hand-in-hand with NASA and the scien- tific community to be sure future missions will be fruitful, exciting, and successful. It is important for the Decadal Committee to consider and comment on the future plans of the DSN to maximize the total NASA return on investment for these missions. 1 Introduction NASA’s Deep Space Network (DSN) is the principle conduit for information passing between spacecraft beyond geocentric orbit (GEO) and the Earth.

  • Deep Space Network: the Next 50 Years1
    Deep Space Network: The Next 50 Years1 Dr. Leslie J. Deutsch2, Dr. Stephen A. Townes Jet Propulsion Laboratory, California Institute of Technology Philip E. Liebrecht, Pete A. Vrotsos, Dr. Donald M. Cornwell National Aeronautics and Space Administration In 2014, NASA’s Deep Space Network (DSN) celebrated its 50th year of enabling explora- tion of the Moon, Solar System planets, and beyond. During those 50 years, the DSN has grown along with the associated spacecraft flight systems, providing some 13 orders of mag- nitude communications systems improvement. It has also contributed to many of the world’s most important scientific discoveries and provided substantial technological spinoffs that have become part of everyday life on Earth. Studies of the next 25 years indicate that deep space missions will need an order of magnitude increased communications performance per decade – and this is likely to continue beyond that time. As exhibited by this meeting, anoth- er major change happening right now is the emergence of a standardized international community for tracking deep space missions. The future definitely involves increased inter- national cooperation. This paper explains the near term plans already underway for the DSN. We also consider the plans and possibilities for deep space optical communications. Fi- nally, we will discuss opportunities for international participation in the next 50 years of deep space exploration.
