The Origins Space Telescope will trace the history of our origins from the time dust and heavy elements permanently altered the cosmic landscape to present-day life. How did galaxies evolve from the earliest galactic systems to those found in the Universe today? How do habitable planets form? How common are life-bearing worlds? To answer these alluring questions, Origins will operate at mid- and far-infrared (IR) wavelengths and offer powerful spectroscopic instruments and sensitivity three orders of magnitude better than that of the Herschel Space Observatory, the largest telescope flown in space to date. We describe the baseline concept for Origins recommended to the 2020 US Decadal Survey in Astronomy and Astrophysics. The baseline design includes a 5.9-m diameter telescope cryocooled to 4.5 K and equipped with three scientific instruments. A mid-infrared instrument (Mid-Infrared Spectrometer and Camera Transit spectrometer) will measure the spectra of transiting exoplanets in the 2.8 to 20  μm wavelength range and offer unprecedented spectrophotometric precision, enabling definitive exoplanet biosignature detections. The far-IR imager polarimeter will be able to survey thousands of square degrees with broadband imaging at 50 and 250  μm. The Origins Survey Spectrometer will cover wavelengths from 25 to 588  μm, making wide-area and deep spectroscopic surveys with spectral resolving power R  ∼  300, and pointed observations at R  ∼  40,000 and 300,000 with selectable instrument modes. Origins was designed to minimize complexity. The architecture is similar to that of the Spitzer Space Telescope and requires very few deployments after launch, while the cryothermal system design leverages James Webb Space Telescope technology and experience. A combination of current-state-of-the-art cryocoolers and next-generation detector technology will enable Origins’ natural background-limited sensitivity.

Distribution or reproduction of this work in whole or in part requires full attribution of the original publication, including its DOI. Received: 13 June 2020; Accepted: 2 December 2020; Published: 6 January 2021. We took excerpts from the SPIE Proceedings paper “The Origins Space Telescope,” in Proc. SPIE, 11115-25 (2019) and from the Origins Space Telescope Mission Concept Study Final Report. The authors are grateful to the many institutions that sponsored and contributed to the successful Origins Space Telescope mission concept study. To enable the community to prepare for the 2020 Decadal Survey, the National Aeronautics and Space Agency, NASA, sponsored studies of four large mission concepts, of which Origins was one. We thank NASA for funding these studies. NASA’s Goddard Space Flight Center (GSFC) contributed substantial additional labor support, which enabled us to explore options, make well-informed engineering decisions, and develop an executable mission concept. The Japan Aerospace Exploration Agency, JAXA, the Canadian Space Agency, CSA, and a Centre National d’ Études Spatiales (CNES)-led European consortium actively participated in the study, with each enabling their team members’ travel to study team meetings and concurrent engineering sessions. JAXA and the European consortium each contributed an instrument design. Domestic study participants included many academic institutions, several NASA centers (Ames Research Center and Marshall Space Flight Center, as well as GSFC), the Caltech Jet Propulsion Laboratory, and industry (Ball Aerospace, Northrop-Grumman, Lockheed-Martin, and L3 Harris), as reflected in the authors’ affiliations. Finally, the authors wish to express their deep gratitude to the hundreds of community members worldwide who contributed to the Origins mission concept study by sharing their thoughts on science priorities, reviewing the science case and engineering designs, developing graphics, formatting reports, taking notes, managing study resources, and making travel arrangements. It took a village. Finally, we thank three JATIS reviewers, whose feedback on the manuscript led to significant improvements.
