Abstract

This paper examines the architectural considerations for one of the designs being considered for the Origins Space Telescope (OST) a future far infra-red (~6-600 µm) space-based observatory. OST requires the temperature of the instruments and optics to operate at temperatures less than 4 Kelvin. Achieving these very low temperatures throughout the optical train in an executable and verifiable design is the defining architectural challenge for OST. This paper will discuss the main elements of OST’s thermal design, cooling, parasitics and thermal verification. This paper will include a discussion of how to modify the JWST for application in the far infra-red.
