The Goddard team provided the critical optical elements, <a href=\"https:\/\/www.nasa.gov\/feature\/goddard\/2023\/nasa-completes-heart-of-roman-space-telescope-s-primary-instrument\" rel=\"noopener\">focal plane system<\/a>, <a href=\"https:\/\/www.nasa.gov\/feature\/goddard\/2023\/goddard-team-builds-tests-calibrator-for-nasa-s-roman-in-record-time\" rel=\"noopener\">relative calibration system<\/a>, and the instrument command and data handling electronics. Then engineers from both teams put all these building blocks together in a clean room in Boulder, Colorado, mechanically and electrically integrating the components into one system. Now, the team will complete full environmental testing in space-like conditions before delivering the WFI to Goddard in summer 2024. Once there, it will join other observatory systems for integration and testing, as the mission gets ready to launch no later than May 2027.<\/p>\n\n\n\n<p>The WFI is a 288-megapixel <a href=\"https:\/\/roman.gsfc.nasa.gov\/science\/WFI_technical.html\" rel=\"noopener\">infrared camera<\/a> that will give Roman the same angular resolution as the Hubble Space Telescope but with at least 100 times Hubble\u2019s field of view. Its sweeping cosmic surveys will help scientists discover new and uniquely detailed information about planets beyond our solar system, untangle mysteries like <a href=\"https:\/\/www.nasa.gov\/feature\/nasa-s-roman-mission-will-test-competing-cosmic-acceleration-theories\" rel=\"noopener\">dark energy<\/a>, and map how matter is structured and distributed throughout the cosmos. The mission\u2019s broad, crisp view will produce an extraordinary resource for a wide range of additional investigations.<\/p>\n\n\n\n<p>\u201cOverall, Roman\u2019s camera greatly exceeds the mission\u2019s performance requirements, including the operational capabilities of the camera detectors,\u201d said Julie McEnery, Roman\u2019s project scientist at Goddard. \u201cSo now we get to explore how much better Roman\u2019s surveys will be, and what we\u2019ll be able to do with the extra scientific riches they produce.\u201d<\/p>\n\n\n<div id=\"\" class=\"hds-media hds-module wp-block-image\"><div class=\"margin-left-auto margin-right-auto nasa-block-align-inline\"><div class=\"hds-media-wrapper margin-left-auto margin-right-auto\"><figure class=\"hds-media-inner hds-cover-wrapper hds-media-ratio-none \"><a href=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/09\/wfi-x-ray-v2.gif\"><img loading=\"lazy\" decoding=\"async\" width=\"320\" height=\"468\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2023\/09\/wfi-x-ray-v2.gif?w=320\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"A large piece of space hardware wrapped in a gray material stands vertically in the center of a bright room.
