It consists of 10 mirrors, including the 7.9-foot (2.4-meter) primary mirror seen at the base in this image, and is called the IOA (Imaging Optical Assembly). Engineers recently integrated and tested the IOA at L3Harris Technologies in Rochester, New York.<\/div><div class=\"hds-credits\">Credit: NASA\/Chris Gunn<\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p>Engineers at L3Harris Technologies in Rochester, New York, have combined all 10 mirrors for NASA\u2019s Nancy Grace Roman Space Telescope. Preliminary tests show the newly aligned optics, collectively called the IOA (Imaging Optics Assembly), will direct light into Roman\u2019s science instruments extremely precisely. This will yield crisp images of space once the observatory launches.<\/p>\n\n\n\n<p>\u201cThis is the pre-launch first light, our first time seeing through the entire telescope,\u201d said Joshua Abel, the lead systems engineer for the Roman Space Optical Telescope Assembly at NASA\u2019s Goddard Space Flight Center in Greenbelt, Maryland. \u201cWe\u2019re excited to enter the next phase of the project!\u201d<\/p>\n\n\n\n<p>Each of Roman\u2019s mirrors had passed individual tests, but this was the first time they were assessed together. Engineers had to make sure light would move through all of the optics in a tightly controlled way, or else the telescope\u2019s images would appear blurred.<\/p>\n\n\n\n<p>\u201cThe telescope\u2019s optics are crucial for all of Roman\u2019s future observations,\u201d said Bente Eegholm, an optical engineer working on Roman\u2019s Optical Telescope Assembly at Goddard. \u201cIn addition to the large primary mirror and the secondary mirror, eight relay mirrors serve Roman\u2019s two science instruments. All 10 telescope mirrors need to be aligned to well within the width of a human hair in order to optimize the telescope\u2019s imaging quality such that Roman can fully achieve its science goals.\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-fit \"><img loading=\"lazy\" decoding=\"async\" width=\"1638\" height=\"2048\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/wfi-optical-path-copyrevc.jpg?w=1638\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"Image showing the path light will travel through Roman's mirrors\" style=\"transform: scale(1); transform-origin: 50% 50%; object-position: 50% 50%; object-fit: cover;\" block_context=\"nasa-block\" srcset=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/wfi-optical-path-copyrevc.jpg 2048w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/wfi-optical-path-copyrevc.jpg?resize=240,300 240w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/wfi-optical-path-copyrevc.jpg?resize=768,960 768w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/wfi-optical-path-copyrevc.jpg?resize=819,1024 819w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/wfi-optical-path-copyrevc.jpg?resize=1229,1536 1229w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/wfi-optical-path-copyrevc.jpg?resize=1638,2048 1638w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/wfi-optical-path-copyrevc.jpg?resize=320,400 320w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/wfi-optical-path-copyrevc.jpg?resize=480,600 480w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/wfi-optical-path-copyrevc.jpg?resize=720,900 720w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/wfi-optical-path-copyrevc.jpg?resize=960,1200 960w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2024\/04\/wfi-optical-path-copyrevc.jpg?resize=1600,2000 1600w\" sizes=\"(max-width: 1638px) 100vw, 1638px\" \/><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">An optical technician lays on a diving board suspended between NASA’s Nancy Grace Roman Space Telescope’s primary and secondary mirrors. The photo is a projected reflection through the telescope\u2019s optical path. The technician shines a beam of light through the optical system toward the future location of the Wide Field Instrument, showing how light from cosmic sources will travel through the telescope once the mission launches.<\/div><div class=\"hds-credits\">Credit: NASA\/Chris Gunn<\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p>The meticulous month-long alignment process involved a series of iterations to bring test images into ever-sharper focus. Once the mirrors were all properly situated, technicians permanently locked them in place. Three of the mirrors will still be movable in space thanks to actuators \u2013 mechanisms that control the mirrors\u2019 positions \u2013 which will allow astronomers to fine-tune the alignment even further once Roman begins its observations.<\/p>\n\n\n\n<p>The IOA\u2019s vision test establishes a baseline for upcoming vibration and acoustic tests. Engineers will compare measurements from before and after those tests to make sure the optics will withstand the strong shaking and intense sound waves during launch.<\/p>\n\n\n\n<p>After that, the IOA will have a final \u201ceye\u201d exam \u2013 this time in vacuum conditions at its cold operational temperature. Materials expand and contract with temperature shifts, and Roman\u2019s optics will go from room temperature conditions on Earth to a frigid 9 degrees Fahrenheit (minus 13 degrees Celsius) in space.<\/p>\n\n\n\n<p>\u201cOur prediction of the small change we expect to see going from ambient to these colder temperatures is very important,\u201d Abel said. The test will also measure the IOA\u2019s performance in extremely low pressure to assess how it will operate in the vacuum of space.<\/p>\n\n\n\n<p>\u201cThe joint team from L3Harris and NASA has fully achieved the goals of the test,\u201d said Scott Smith, Roman telescope manager at Goddard. \u201cThe technicians and engineers have executed a successful optical test with precision and excellence while maintaining their commitments to schedule.\u201d <\/p>\n\n\n\n<p>The entire Optical Telescope Assembly, of which the IOA is a core component, is expected to be complete and delivered to Goddard this fall.<\/p>\n\n\n\n<p>For more information about the Roman Space Telescope visit: <a href=\"https:\/\/roman.gsfc.nasa.gov\/\" rel=\"noopener\">www.roman.gsfc.nasa.gov<\/a> or <a href=\"http:\/\/www.nasa.gov\/roman\">www.nasa.gov\/roman<\/a>.
