“…An example of one such system is the MESSENGER (MEcury Surface, Space ENvironment, GEochemistry, and Ranging) mission to study planet Mercury as illustrated in [2]. Owing to the fact that this is a deep space mission wherein large round-trip travel times would be incurred with severe downlink constraints, it is essential to adopt a file based secondary storage mechanism for science data.…”

Modeling the space environment of a planet including three dimensional dynamic "imaging" of the magnetosphere warrants the use of constellations of many spacecrafts. Communication among the various space assets and exchange of mission data for more efficient storage and analysis call for a dynamic and reliable technology capable of managing ad-hoc requests subjected to system and environmental constraints. In this paper 12 , we propose a cognitive radio architecture that can be used as an extension to space based software defined radio. Simulink is used to demonstrate the behavioral model of a system that represents the executable specifications. In order to illustrate some of the key features of the architecture, a basic model has been created in Simulink. This modeling would enable future implementation of the architecture and support any debugging or restructuring.

The MErcury Surface, Space ENvironment, GEochemistry, and Ranging (MES-SENGER) spacecraft was designed and constructed to withstand the harsh environments associated with achieving and operating in Mercury orbit. The system can be divided into eight subsystems: structures and mechanisms (e.g., the composite core structure, aluminum launch vehicle adapter, and deployables), propulsion (e.g., the state-of-the-art titanium fuel tanks, thruster modules, and associated plumbing), thermal (e.g., the ceramic-cloth sunshade, heaters, and radiators), power (e.g., solar arrays, battery, and controlling electronics), avionics (e.g., the processors, solid-state recorder, and data handling electronics), software (e.g., processor-supported code that performs commanding, data handling, and spacecraft control), guidance and control (e.g., attitude sensors including star cameras and Sun sensors integrated with controllers including reaction wheels), radio frequency telecommunications (e.g., the spacecraft antenna suites and supporting electronics), and payload (e.g., the science instruments and supporting processors). This system architecture went through an extensive (nearly four-year) development and testing effort that provided the team with confidence that all mission goals will be achieved.
