Abstract
Reuse of a proven design can save a mission significant time, money and risk. At least two of the decadal missions, HabEx and Origins Space Telescope, are considering the reuse of some or most of the James Webb Space Telescope flight hardware design for one of their studied architectures. Another, LUVOIR, will benefit highly from learning the necessary lessons on I&T and architecture reuse. This paper compares the performance of the Webb Telescope against the requirements for the HabEx and OST missions to identify the subsystem designs that can be reused without revisions. We will also highlight the areas where new work must be accomplished. We conclude with a net assessment that that shows Webb reuse is a viable program option and a good deal for science.
