This paper discusses typical manned Mars exploration needs for telecommunications, including preliminary navigation support functions.It is a brief progress report on an ongoing study program within the current NASA Jet Propulsion Laboratory Deep Space Network (DSN) activities.In support of NASA Office of Exploration mission requirements, system performance & design options -including DSN architecture, and technology needs to support these exploration opportunities over the next 25 years are outlined. A typical Mars exploration case is defined, and support approaches comparing microwave and optical frequency performance for both local in -situ and Mars -Earth links are described. An objective of this paper is also to identify optical telecommunication and navigation technology development opportunities in a Mars exploration program. A local Mars system telecommunication relay and navigation capability for service support of all Mars missions has been proposed as part of an overall Solar System communications network. The effects of light -time delay and occultations on real -time mission decision -making is discussed; the availability of increased local mass data storage may be more important than increasing peak data rates to Earth.The long term frequency use plan will most likely include a mix of microwave, millimeterwave and optical link capabilities to meet a variety of deep space mission needs.
