Session
Technical Session IIB: Advanced Operations Concept Systems
Abstract
The Solar Terrestrial Relations Observatory (STEREO) is a new NASA mission designed to increase the understanding of the origin and consequences of coronal mass ejections (CMEs). The mission will consist of two identical spacecraft at approximately lAU from the Sun: one drifting ahead of the Earth and one behind. Simultaneous image pairs will be obtained by the spacecraft at gradually increasing angular separations over the course of the 2-year mission. The spacecraft launch date is scheduled for 2003. The concept of operations for this mission consists of independent and decoupled instrument and spacecraft bus operations. The Science Operations Teams will generate the instrument commands to accomplish the science objectives, and the STEREO Mission Operations Team (MOT) will support the spacecraft bus. All spacecraft servicing, including commanding and science data recovery, will occur during a daily ground track with the Deep Space Network. All science data will be flowed in near real-time to the Science Operations Center via the Internet. During the normal operations phase of the mission, each track will run autonomously with a small MOT to conduct planning and assessment tasks. The spacecraft and ground system will be highly autonomous, making this mission ideal for "lights out" operations.
