The Deep Space System Technology Program (DSSTP) is managed at the Jet Propulsion Laboratory for the National Aeronautics and Space Administration (NASA) and is also called X2000. X2000 is organized to create “cores” of advanced flight and ground systems for the exploration of the outer planets and beyond; cores are the engineering elements of flight and ground systems. Mission specific elements such as instruments will be developed by another team. Each X2000 delivery gets its requirements from a set of planned missions, or “mission customers”. The first set of missions leads to some outstanding requirements: 1. Long-life (12-14 years for a mission to the Kuiper belt). 2. Total Ionizing Dose (TID) of 4 Mrad (for a Europa Orbiter—after only 30 days in orbit). 3. Average power consumption less than or equal to 150 Watts. 4. Autonomous operations that result in an extreme reduction in operations costs. 5. Large scale software re-use must be enabled. The technologies needed to meet these requirements cover a broad spectrum and revolutionize the designs of flight and ground systems JPL and NASA will fly to the outer planets. This paper describes the X2000 first delivery and its technologies following a brief overview of the program.
