Architecture frameworks help manage complex systems by organizing data in a common way. The Department of Defense Architecture Framework was used to study satellites, like the Hubble Space Telescope, to understand how they work and how they can be improved. By using a software tool called CORE, the researchers were able to create detailed views of the Hubble's architecture. They found that this framework can be used to analyze and improve systems, like planning for servicing missions to extend the life of spacecraft.
