Abstract

The Nancy Grace Roman Telescope (RST) is a NASA observatory designed to unravel the secrets of dark energy and dark matter, search for and image exoplanets, and explore many topics in infrared optics. Scheduled to launch in the mid-2020s, this 2.4 meter aperture telescope has a field of view 100 times greater than the Hubble Space Telescope. The mission is currently in its construction phase, where integrated modeling between thermal, structural, and optical models of the observatory is necessary to demonstrate science quality images over the range of operational parameters. This presentation discusses the crosschecks used in the integrated modeling process for RST, including the various flows of data between the modeling disciplines, and summarizes the current predicted performance. Additionally, several optical modeling tools are discussed, along with the specific requirements they are meant to address.
