Abstract
The Virtual Super-Resolution Optics with Reconfigurable Swarms (VISORS) mission is a multi-CubeSat distributed telescope which will image the solar corona to investigate the existence of underlying energy release mechanisms. Such a task requires angular resolutions of less than 0.2 arc-seconds in extreme ultraviolet, which cannot be economically done with a conventional space telescope. Performing such a mission requires unprecedented relative navigation tolerances, a need for active collision avoidance, a development of intersatellite communication, and a propulsion system that enables the relative navigation maneuvers. The mission was initially conceived as a three 3U satellite formation in the NSF CubeSat Innovations Ideas Lab to address NSF science goals with innovative technologies. Once beginning conceptual subsystem design, it was evident that significant constraints linked to the three 3U satellite formation configuration limit the likelihood of mission success and increase mission risk. A trade study was conducted to determine potential resolutions to the problems associated with the initial three 3U satellite formation configuration. The completion of the trade study resulted in a major design change to a two 6U satellite configuration that resolved the issues associated with the initial configuration, improved mission success while reducing risk, and intends to incorporate novel CubeSat technologies, all of which enable the mission to move forward. This paper discusses the path that led the team to conduct the trade study, the design alternatives considered, and the innovative subsystem technologies that were conceived as a result of updating the satellite formation configuration.
