The HabEx mission concept is a large (~4 to 6.5m) diffraction-limited optical space telescope, providing unprecedented resolution and contrast in the optical, with extensions into the near UV and near infrared domains. \u0000\u0000The primary goal of HabEx is to answer fundamental questions in exoplanet science, searching for and characterizing potentially habitable worlds, providing the first complete “family portraits” of planets around our nearest Sun-like neighbors and placing the solar system in the context of a diverse set of exoplanets. \u0000At the same time, HabEx will enable a broad range of Galactic, extragalactic, and solar system astrophysics, from resolved stellar population studies that inform the stellar formation history of nearby galaxies, to characterizing the life cycle of baryons as they flow in and out of galaxies, to detailed studies of bodies in our own solar system.\u0000\u0000We report here on our team’s efforts in defining a scientifically compelling HabEx mission that is technologically executable, affordable within NASA’s expected budgetary envelope, and timely for the next decade. In particular, we present architectures trade study results, quantify technical requirements and predict scientific yield for a small number of design reference missions, all with broad capabilities in both exoplanet science and cosmic origins science. \u0000\u0000This research was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration.","PeriodicalId":225169,"journal":{"name":"Space Telescopes and Instrumentation 2018: Optical, Infrared, and Millimeter Wave","volume":"183 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134270454","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Apodized Pupil Lyot Coronagraph (APLC) is one of the baselined mask technologies to enable 1E10 contrast observations in the habitable zones of nearby stars. The LUVOIR concept uses a large, segmented primary mirror (9--15 meters in diameter) to meet its scientific objectives. For such an observatory architecture, the coronagraph performance depends on active wavefront sensing and control and metrology subsystems to compensate for errors in segment alignment (piston and tip/tilt), secondary mirror alignment, and global low-order wavefront errors. Here we present the latest results of the simulation of these effects for different working angle regions and discuss the achieved contrast for exoplanet detection and characterization under these circumstances, including simulated observations using high-fidelity spatial and spectral models of planetary systems generated with Haystacks, setting boundaries for the tolerance of such errors.","PeriodicalId":225169,"journal":{"name":"Space Telescopes and Instrumentation 2018: Optical, Infrared, and Millimeter Wave","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131697854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ambitious goal of identifying a habitable or inhabited world is within reach. The race to find habitable exoplanets has accelerated with the realization that “big Earths” transiting small stars can be both discovered and characterized with current technology, such that the James Webb Space Telescope has a chance to be the first to provide evidence of biosignature gases. Transiting exoplanets require a fortuitous alignment and the fast-track approach is therefore only the first step in a long journey. The next step is sophisticated starlight suppression techniques for large ground-based telescopes now under construction and hopeful future space-based based telescopes to observe small exoplanets directly. These ideas will lead us down a path to where future generations will implement very large space-based telescopes to search thousands of all types of stars for hundreds of Earths to find signs of life amidst a yet unknown range of planetary environments. What will it take to identify habitable worlds with the telescopes available to us?","PeriodicalId":225169,"journal":{"name":"Space Telescopes and Instrumentation 2018: Optical, Infrared, and Millimeter Wave","volume":"130 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122563895","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Finding and characterizing a wide range of exoplanets, including those that might be habitable, is a major goal of the study. Driven by the ambitious science goals is the challenges of the optical design. The paper will present how the optical design meets the unique challenges for coronagraphs on large segmented telescopes to achieve high contrast for a wide wavelength range from 400 nm to 1700 nm, such as the position and size of occulter masks, deformable mirror placement and separation, diffraction from a segmented mirror, tight tolerances on the optical system and each element, etc. Two types of spectrometers are designed after the coronagraph to analyze the spectrum of detected exo-planet signals: one is an Integral Field Spectrograph (IFS), and the other one is a High Resolution Spectrometer (HRS). These two spectral instruments will provide information scientists requested in searching for habitable planets. The optical designs, unique challenges, and the solutions for all coronagraph and spectral instruments will be presented. Their specifications derived from science goal will be detailed.","PeriodicalId":225169,"journal":{"name":"Space Telescopes and Instrumentation 2018: Optical, Infrared, and Millimeter Wave","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131408103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
