Hrybyk<\/strong><\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p>Large telescopes that could be used for detecting and analyzing Earth-like planets in orbit around other stars or for peering back in time to observe the very early universe may not necessarily have to be built and assembled on the ground. In the future, NASA could construct them in space.<\/p>\n\n\n\n<p>A NASA engineer was selected for a flight opportunity to show that an advanced thin-film manufacturing technique called atomic layer deposition, or ALD, could apply wavelength-specific reflective coatings onto a sample in space \u2014 one of the first steps in ultimately realizing the vision of constructing and assembling large telescopes in microgravity.<\/p>\n\n\n\n<p>\u201cWe technologists think next-generation telescopes larger than 20 meters in diameter will be built and assembled in orbit,\u201d said Vivek Dwivedi, an engineer at NASA\u2019s Goddard Space Flight Center in Greenbelt, Maryland, and an expert in ALD technology. \u201cInstead of manufacturing the mirrors on the ground, why not print them in space? But you don\u2019t have a telescope mirror unless you coat it with a highly reflective material. Our idea is to show that we could coat an optic in space using this technique, which we\u2019ve used on the ground and understand the processes,\u201d Dwivedi said.<\/p>\n\n\n\n<p>He and his collaborator, University of Maryland professor Raymond Adomaitis, will now have a chance to demonstrate the concept in space for the first time.<\/p>\n\n\n\n<p><strong>Blue Origin Suborbital Flight Test<\/strong><\/p>\n\n\n\n<p>Recently, NASA\u2019s Space Technology Mission Directorate\u2019s <a href=\"https:\/\/www.nasa.gov\/directorates\/spacetech\/flightopportunities\/index.html\" rel=\"noopener\">Flight Opportunities program<\/a> selected Dwivedi and Adomaitis to fly a football-sized ALD chamber aboard a Blue Origin New Shepard rocket. The launch will provide three minutes of microgravity, long enough for the automated payload to apply a thin film of a well-known ALD material, alumina, onto a two-inch silicon wafer. \u201cAlumina is a bread-and-butter material in ALD applications,\u201d Dwivedi said. \u201cIt\u2019s been extensively researched.\u201d<\/p>\n\n\n\n<p>Commonly used by industry, ALD involves placing a substrate or sample inside an oven-like reactor chamber and pulsing different types of gases to create a smooth, highly uniform film whose layers are no thicker than a single atom.<\/p>\n\n\n\n<p><strong>ALD-coated Samples in Space<\/strong><\/p>\n\n\n\n<p>ALD may also have applications for dust mitigation, another challenge NASA is working to solve. Currently, <a href=\"https:\/\/www.nasa.gov\/feature\/goddard\/2019\/nasa-s-coating-technology-could-help-resolve-lunar-dust-challenge\" rel=\"noopener\">ALD-coated samples are being exposed to plasma from an experiment pallet aboard the International Space Station<\/a>. Dwivedi and Goddard technologist Mark Hasegawa created these samples to test whether indium tin oxide \u2014 an effective compound for dissipating electrical charges \u2014 might be applied to paints and other materials to prevent lunar dust from adhering to rovers, instruments, and spacesuits.<\/p>\n\n\n\n<p>Mitigating the dust problem is considered one of NASA\u2019s thorniest challenges as the agency plans to establish a sustainable presence on the Moon under the <a href=\"https:\/\/www.nasa.gov\/specials\/artemis\/\" rel=\"noopener\">Artemis program.<\/a><\/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\/2020\/05\/metro.png\"><img loading=\"lazy\" decoding=\"async\" width=\"548\" height=\"466\" src=\"https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/05\/metro.png?w=548\" class=\"attachment-2048x2048 size-2048x2048\" alt=\"Map of the DC metro area rail system with overlapping circles around it. \" 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\/2020\/05\/metro.png 548w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/05\/metro.png?resize=300,255 300w, https:\/\/www.nasa.gov\/wp-content\/uploads\/2020\/05\/metro.png?resize=400,340 400w\" sizes=\"(max-width: 548px) 100vw, 548px\" \/><\/a><\/figure><figcaption class=\"hds-caption padding-y-2\"><div class=\"hds-caption-text p-sm margin-0\">If scientists scaled a silicon wafer to the size of the Washington metropolitan area and placed it inside an atomic layer deposition chamber, they could apply a layer of material that varied no more than 60 microns in thickness, as shown in this illustration.<\/div><div class=\"hds-credits\"><strong>NASA<\/strong><\/div><\/figcaption><\/div><\/div><\/div>\n\n\n<p>For in-space manufacturing, ALD offers a distinct advantage, Dwivedi said.
