| dc.description.abstract | 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? We describe how Origins was designed to answer these alluring questions. We discuss the key decisions taken by the Origins mission concept study team, the rationale for those choices, and how they led through an exploratory design process to the Origins baseline mission concept. To understand the concept solution space, we studied two distinct mission concepts and descoped the second concept, aiming to maximize science per dollar and hit a self-imposed cost target. We report on the study approach and describe the concept evolution. The resulting baseline design includes a 5.9-m diameter telescope cryocooled to 4.5 K and equipped with three scientific instruments. The chosen architecture is similar to that of the Spitzer Space Telescope and requires very few deployments after launch. The cryo-thermal system design leverages James Webb Space Telescope technology and experience. | en_US |
| dc.description.sponsorship | We took excerpts from the SPIE Proceedings paper “The Origins Space Telescope: mission concept overview,” in Proc. SPIE 10698-40 (2018) 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 Administration (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 CNES-led European consortium actively participated in the study, with each contributing an instrument design and enabling their team members’ travel to study team meetings and concurrent engineering sessions. 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. 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. Last, but not least, we thank three JATIS reviewers, whose feedback on the original manuscript led to substantial improvements. | en_US |
