Rubin Observatory technical challenges and resolutions

The Vera C. Rubin Observatory is an astronomical survey facility nearing completion in Chile. Its mission is to accomplish the 10-year Legacy Survey of space and Time (LSST) survey - a 6-color optical imaging survey of the southern sky. The science mission for the LSST resulted in demanding requirements for optical performance and system dynamics. Producing a Telescope and an Observatory meeting these requirements resulted in multiple technical challenges which were encountered and resolved during the design and construction of the project. Resolving these challenges has impacted the assembly and integration of the overall system. Analyses were performed and solutions were developed. This paper provides a general overview of these challenges and highlights some specific examples where resolutions were found and implemented.
