MBSE in Development: SMAP Pilot Project
Customer-focused objective: Provide value to a flight project using Model-Based Systems Engineering (MBSE) methodology and products. Institution-focused objective: Advance and improve our systems engineering practices, leveraging MBSE where applicable: Streamline our interfaces across JPL Divisions, to provide better cross-organization products; Streamline our interfaces across lifecycle phase boundaries; Update our SE practices to make them more competitive and able to handle systems of ever-increasing complexity.

The X2000 Program: An Institutional Approach to Enabling Smaller Spacecraft
NASA's X2000 Program is important for many reasons - It develops the technology that will enable new types of deep space space exploration - It is a new, faster and cheaper process for technology infusion into NASA missions - It transfers these capabilities to US industry so they are available for future spacecraft. Many of these new capabilities are relevant to Earth missions as well X2000 will work with the NASA Goddard Space Flight Center (and others) to help make these capabilities available to a larger community.

NASA's X2000 Program: An Institutional Approach to Enabling Smaller Spacecraft
The number of NASA science missions per year is increasing from less than one to more than six. At the 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 missions.

(abstract) Follow-on Missions for the Pluto Spacecraft
The Pluto Fast Flyby mission development baseline consists of 2 identical spacecraft (120 - 165 kg) to be launched to Pluto/Charon in the late 1990s. These spacecraft are intended to fly by Pluto and Charon in order to perform various remote-sensing scientific investigations and have a mission development cost less than $400M (FY92$) through launch plus 30 days. The long-life (6 - 10 years) mission duration and lightweight design make the Pluto spacecraft a good candidate for a number of other flyby missions to objects in the outer Solar System, and some of these were investigated by JPL in cooperation with NASA Code SL's (Solar System Exploration) Outer Planets Science Working Group (OPSWG) in 1993. The JPL team looked at what it would mean to fly one of these missions (if a third spacecraft were available) in terms of flight time, spacecraft modifications, and science payload resources; the OPSWG recommended science investigation modifications for the different targets based on the available resources. The missions could, in many cases, utilize less capable launch vehicles, thereby reducing life-cycle cost of the mission. Examples of the sort of targets which were investigated and looked attractive in terms of flight time are: Uranus, Neptune, Uranus/Neptune dual-mission, Trojan asteroids (624 Hektor, 617 Patroclus, others), 5145 Pholus (the reddest object known in the solar system), and Kuiper Belt objects (i.e., 1992 QB1) . This paper will present the results of this investigation in terms of potential science return, performance, and the potential for life-cycle cost reductions through inheritance from Pluto Fast Flyby .
