Habitable Exoplanet Imaging Mission
Name	Habitable Exoplanet Imaging Mission
Operator	NASA, European Space Agency, Canadian Space Agency

Habitable Exoplanet Imaging Mission is a proposed space telescope mission that aims to directly image exoplanets in the habitable zones of nearby stars, such as Proxima Centauri, TRAPPIST-1, and Kepler-452. The mission is a collaboration between NASA, European Space Agency, and Canadian Space Agency, with contributions from University of California, Berkeley, California Institute of Technology, and University of Toronto. The mission's primary goal is to search for biosignatures in the atmospheres of exoplanets using advanced spectroscopy techniques, similar to those employed by the Hubble Space Telescope and James Webb Space Telescope.

Introduction

The Habitable Exoplanet Imaging Mission is designed to build upon the discoveries made by previous exoplanet-hunting missions, such as the Kepler space telescope and the Transiting Exoplanet Survey Satellite (TESS). The mission will utilize a powerful space telescope to directly image exoplanets and study their atmospheres, which will provide valuable insights into the possibility of life beyond Earth. The mission's scientific objectives are aligned with those of the NASA Exoplanet Exploration program and the European Space Agency's PLATO mission. The mission will also draw upon the expertise of renowned exoplanet scientists, such as Sara Seager and Didier Queloz, who have made significant contributions to the field of exoplanetary science.

Mission_Objectives

The primary objectives of the Habitable Exoplanet Imaging Mission are to directly image exoplanets in the habitable zones of nearby stars, such as Alpha Centauri and Barnard's Star, and to search for biosignatures in their atmospheres. The mission will also study the properties of exoplanet atmospheres, including their composition, temperature, and pressure, using advanced spectroscopy techniques, such as those developed by NASA's Goddard Space Flight Center and the European Southern Observatory. The mission's objectives are closely aligned with those of the NASA Astrobiology program and the European Space Agency's Astrobiology program. The mission will also collaborate with other exoplanet-hunting missions, such as the HabEx mission and the LUVOIR mission, to advance our understanding of exoplanetary science.

Spacecraft_Design

The Habitable Exoplanet Imaging Mission spacecraft is designed to be a space telescope with a high-contrast imaging system, similar to those used by the Hubble Space Telescope and the Spitzer Space Telescope. The spacecraft will be equipped with a primary mirror and a secondary mirror to collect and focus light from distant stars and exoplanets. The spacecraft will also be equipped with advanced thermal control systems to maintain a stable temperature and minimize thermal noise. The spacecraft's design is based on the NASA Space Technology Mission Directorate's Space Technology Roadmaps and the European Space Agency's Space Technology Programme. The mission will also utilize advanced propulsion systems, such as those developed by NASA's Jet Propulsion Laboratory and the European Space Agency's Advanced Concepts Team.

Scientific_Instruments

The Habitable Exoplanet Imaging Mission spacecraft will be equipped with a range of scientific instruments, including a high-contrast imager, a spectrograph, and a polarimeter. The high-contrast imager will be used to directly image exoplanets and study their atmospheres, while the spectrograph will be used to analyze the composition of exoplanet atmospheres. The polarimeter will be used to study the properties of exoplanet atmospheres, including their polarization and magnetic fields. The mission's scientific instruments are being developed in collaboration with University of California, Los Angeles, University of Oxford, and University of Geneva. The mission will also utilize advanced data analysis techniques, such as those developed by NASA's Ames Research Center and the European Space Agency's European Space Astronomy Centre.

Mission_Timeline

The Habitable Exoplanet Imaging Mission is currently in the concept study phase, with a planned launch date in the late 2020s. The mission will undergo a series of review and approval processes, including a NASA Senior Review and a European Space Agency Programme Board review. The mission will also undergo a series of testing and validation phases, including a spacecraft integration and testing phase and a scientific instrument calibration phase. The mission will be launched on a heavy-lift launch vehicle, such as the SpaceX Falcon Heavy or the Ariane 6, and will be operated by a team of scientists and engineers from NASA, European Space Agency, and Canadian Space Agency.

Expected_Outcomes

The Habitable Exoplanet Imaging Mission is expected to make significant contributions to our understanding of exoplanetary science and the search for life beyond Earth. The mission will provide high-resolution images of exoplanets and their atmospheres, which will allow scientists to study the properties of exoplanet atmospheres and search for biosignatures. The mission will also provide valuable insights into the formation and evolution of exoplanetary systems, including the delivery of water and organic molecules to exoplanets. The mission's expected outcomes are closely aligned with those of the NASA Exoplanet Exploration program and the European Space Agency's PLATO mission. The mission will also contribute to the development of new technologies and methods for exoplanet detection and characterization, such as those being developed by NASA's Exoplanet Exploration program and the European Space Agency's Advanced Concepts Team.
