Transforming the Deep Space Network into the Interplanetary Network
Space exploration missions are undergoing a significant transformation as are the expectations of their scientific investigators and the public who participate in these great voyages of exploration.

Space Infrared Telescope Facility (SIRTF) - Operations concept
The development and operations costs of the Space IR Telescope Facility (SIRTF) are discussed in the light of minimizing total outlays and optimizing efficiency. The development phase cannot extend into the post-launch segment which is planned to only support system verification and calibration followed by operations with a 70-percent efficiency goal. The importance of reducing the ground-support staff is demonstrated, and the value of the highly sensitive observations to the general astronomical community is described. The Failure Protection Algorithm for the SIRTF is designed for the 5-yr lifetime and the continuous venting of cryogen, and a science driven ground/operations system is described. Attention is given to balancing cost and performance, prototyping during the development phase, incremental development, the utilization of standards, and the integration of ground system/operations with flight system integration and test.

Ground systems and operations concepts for the Space Infrared Telescope Facility (SIRTF)
Key requirements and ground systems implementation strategy for SIRTF which presents a significant challenge in the operational phase of the mission are discussed. The facility is aimed at reliably integrating a guaranteed time program, requests from about 200 guest observer teams per year, and observatory maintenance. SIRFT is characterized by the five-year life time due to cryogen boil-off which means that the ground system must be fully operational at launch and must operate with an efficiency and timeliness rarely achieved in previous space missions.

High rate data systems
The characteristics of the high resolution imaging spectrometer (HIRIS) and the synthetic aperture radar (SAR) are described with consideration given to the source of their high data rates. A functional-level description of the end-to-end data flow for HIRIS and SAR is provided. Attention is also given to major technological challenges that must be met in achieving an implementation of the system. Management issues associated with high rate, high volume data are also discussed.
