Abstract:
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.

 Abstract
The number of NASA science missions per year is increasing from less than one to more than six. Atthe same time, individual mission budgets are smaller and cannot afford their own dedicated technology developments. In response to this, NASA has formed the X2000 Program. This program, which is divided into a set of subsequent “deliveries” will provide the basic avionics, power, communications, and software capability for future science missions. X2000 First Delivery, which will be completed in early 2001, will provide a full-functioned one MRAD tolerant flight computer, power switching electronics, a highly efficient radioisotope power source, and a transponder that provides high-level services at both 8.4 GHz and 32 GHz bands. The X2000 Second Delivery, which will be completed in the 2003 time frame, will enable complete spacecraft in the 10-50 kg class. All capabilities delivered by the X2000 program will be commercialized within the US and therefore will be available for others to use. Although the immediate customers for these technologies are deep space missions, most of the capabilities being delivered are generic in nature and will be equally applicable to Earth Observation mis- sions.

 Abstract
The Advanced Deep Space System Development Program is managed by the Jet Propulsion Laboratory for NASA and is also called X2000. X2000 is organized to create advanced flight and ground systems for the exploration of the outer planets and beyond; it has been created to develop the engineering elements of flight and ground systems. Payloads will be developed by another team. Each X2000 delivery gets its requirements from a set of planned missions, or “mission customers”. The X2000 First Delivery Project supports missions to the Sun (to 4 solar radii), Europa (looking for a liquid ocean), Mars (in support of several Mars missions including a sample return), a comet (including a sample return), and Pluto followed by a trip into the Kuiper belt. This set of missions leads to some outstanding requirements:
  1. Long-life (10-12 years)
  2. Total Ionizing Dose of 4 Mrad (for a Europa Orbiter)
  3. Average power consumption less than or equal to 150 Watts
  4. Autonomous operations that result in an extreme reduction in operations costs.
