![]() ![]() Luchika, Thomas (Pasadena, CA: Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2020) Poberezhskiya, Ilya (Pasadena, CA: Jet Propulsion Laboratory, National Aeronautics and Space Administration, 2020) Roman Space Telescope Coronagraph Engineering Design and Operating Concept We will describe the flow down of key and driving CGI requirements from high level performance to the instrument hardware and software, current instrument configuration and engineering design, operational concept planned for CGI observations, integrated modeling status, and performance predictions. CGI has passed its Preliminary Design Review (PDR) in September 2019 and is working toward the instrument Critical Design Review (CDR) in the spring of 2021. It will work with the obscured 2.4 meter diameter telescope and demonstrate starlight suppression that is up to 3 orders of magnitude deeper than the preceding space-based and ground-based coronagraphs by using active wavefront control in space with deformable mirrors. The coronagraph instrument (CGI) on Roman will demonstrate the technology for direct imaging and spectroscopy of exoplanets around nearby stars. This data will help ensure that the telescope contributes to our increasing knowledge of planets outside of the Solar System and their potential to support life.NASA’s Nancy Grace Roman Space Telescope (formerly known as WFIRST) is a flagship astrophysics mission planned for launch in 2025. Astrobiologists studying the potential for life on extrasolar planets provide valuable insight into mission requirements for the mission. Many astrobiolgists supported by elements of the Astrobiology Program are involved in the development of the Roman Space Telescope mission. The Roman Space Telescope will make observations that could contribute to the discovery of new worlds beyond our solar system and advance the search for extrasolar planets that could be suitable for life. The Roman Space Telescope is designed for a 6 year mission, and will launch on a EELV out of Cape Canaveral. The Coronagraph Instrument will perform high contrast imaging and spectroscopy of dozens of individual nearby exoplanets. It will perform a microlensing survey of the inner Milky Way to find ~2,600 exoplanets. ![]() As the primary instrument, the Wide Field Instrument will measure light from a billion galaxies over the course of the mission lifetime. The Roman Space Telescope will have a field of view that is 100 times greater than the Hubble infrared instrument, capturing more of the sky with less observing time. Roman has been called the “mother” of NASA’s Hubble Space Telescope. The telescope was initially developed as the Wide Field InfraRed Survey Telescope ( WFIRST), and renamed in 2020 to honor Nancy Grace Roman, NASA’s first Chief of Astronomy. The Roman Space Telescope is currently planned for launch in the mid-2020s. ![]() The Nancy Grace Roman Space Telescope – or Roman Space Telescope, for short – is a NASA observatory designed to settle essential questions in the areas of dark energy, exoplanets, and infrared astrophysics. ![]()
