Abstract

The James Webb Space Telescope (JWST), scheduled to launch in 2018, relies almost exclusively on passive, cryogenic cooling for the telescope and instruments. The final stage of cooling is provided by 5 single stage cryogenic radiators. Three of these radiators have been manufactured by Ball Aerospace and represent the state of the art and provide unprecedented performance. This paper discusses the evolution of the requirements and design, and the resulting performance. This paper includes the most mature performance data for Ball Infrared Black (BIRBTM) coating, as well as specialized material property performance and structural properties.
