X2000 flight missions utilizing common modular components

The X2000 First Delivery engineering model advanced technology spacecraft bus is being developed at NASA´s Jet Propulsion Laboratory to enable a challenging and diverse set of interplanetary missions in the first few years of the 21st century. These missions were examined in detail, and a consolidated set of requirements was synthesized to guide the design of the first X2000 bus. A software and hardware architecture was developed for the X2000 bus that is modular, scaleable, and upgradable. It will enable the procurement of highly capable, low mass flight systems that can perform the mission set at a low recurring cost for the X2000 bus or components of the bus used for each mission. An end-to-end integrated Mission Data System is also being developed as part of the X2000 First Delivery to enable more flexible mission operations. A high degree of onboard autonomy is planned to lower the staffing and cost of operations
