Contrails form when aircraft operate in the cold temperatures at high altitudes. The water vapor in their exhaust cools and condenses, and when it interacts with either the soot or other particles in the air, it forms ice crystals. Those contrails can linger in the upper atmosphere for hours, producing localized temperature impacts, which over time can affect climate change.<\/p>\n\n\n\n<p>Alternative fuels, including sustainable aviation fuels, can release fewer soot particles.

Efforts to develop and evaluate sustainable aviation fuels focus on delivering the performance of conventional jet fuel without releasing new carbon dioxide into the environment. These fuels can be derived from sustainable sources such as feedstocks and waste resources.<\/p>\n\n\n\n<p>NASA\u2019s sustainable aviation fuel research is part of the agency\u2019s work to advance the U.S. goal of net-zero aviation greenhouse gas emissions by 2050.<\/p>\n\n\n\n<p>Flight testing remains the gold standard for understanding aerospace innovations and their environmental impacts, making partnerships like ecoDemonstrator and research aircrafts like NASA\u2019s DC-8 important sources for data that can help make aviation more sustainable, protecting the environment and improving life on Earth.<\/p>\n\n\n<div id=\"\" class=\"nasa-gb-align-full width-full maxw-full padding-x-3 padding-y-0 article_a hds-module hds-module-full wp-block-nasa-blocks-credits-and-details\">\n<section class=\"padding-x-0 padding-top-5 padding-bottom-2 desktop:padding-top-7 desktop:padding-bottom-9\">\n\t<div class=\"grid-row grid-container maxw-widescreen padding-0\">\n\t\t<div class=\"grid-col-12 desktop:grid-col-2 padding-right-4 margin-bottom-5 desktop:margin-bottom-0\">\n\t\t\t<div class=\"padding-top-3 border-top-1px border-color-carbon-black\">\n\t\t\t\t<div class=\"margin-bottom-2\">\n\t\t\t\t\t<h2 class=\"heading-14\">Share<\/h2>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"padding-bottom-2\">\n\t\t\t\t\t<ul class=\"social-icons social-icons-round\">\n\t\t\t\t\t\t<li class=\"social-icon social-icon-x\">\n\t\t\t\t\t\t\t<a href=\"https:\/\/x.com\/intent\/tweet?via=NASA&text=NASA%2C%20Partners%20Explore%20Sustainable%20Fuel%E2%80%99s%20Effects%20on%20Aircraft%20Contrails&url=https%3A%2F%2Fwww.nasa.gov%2Fcenters-and-facilities%2Farmstrong%2Fnasa-partners-explore-sustainable-fuels-effects-on-aircraft-contrails%2F\" aria-label=\"Share on X.\">\n\t\t\t\t\t\t\t\t<svg width=\"1200\" height=\"1227\" viewBox=\"0 0 1200 1227\" fill=\"none\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\"><path d=\"M714.163 519.284L1160.89 0H1055.03L667.137 450.887L357.328 0H0L468.492 681.821L0 1226.37H105.866L515.491 750.218L842.672 1226.37H1200L714.137 519.284H714.163ZM569.165 687.828L521.697 619.934L144.011 79.6944H306.615L611.412 515.685L658.88 583.579L1055.08 1150.3H892.476L569.165 687.854V687.828Z\" fill=\"white\"\/><\/svg>\n\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t<\/li>\n\t\t\t\t\t\t<li class=\"social-icon social-icon-facebook\">\n\t\t\t\t\t\t\t<a href=\"https:\/\/www.facebook.com\/sharer.php?u=https%3A%2F%2Fwww.nasa.gov%2Fcenters-and-facilities%2Farmstrong%2Fnasa-partners-explore-sustainable-fuels-effects-on-aircraft-contrails%2F\" aria-label=\"Share on Facebook.\">\n\t\t\t\t\t\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 24 24\" aria-hidden=\"true\"><path d=\"M9 8h-3v4h3v12h5v-12h3.642l.358-4h-4v-1.667c0-.955.192-1.333 1.115-1.333h2.885v-5h-3.808c-3.596 0-5.192 1.583-5.192 4.615v3.385z\"\/><\/svg>\n\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t<\/li>\n\t\t\t\t\t\t<li class=\"social-icon social-icon-linkedin\">\n\t\t\t\t\t\t\t<a href=\"https:\/\/www.linkedin.com\/shareArticle?mini=true&url=https%3A%2F%2Fwww.nasa.gov%2Fcenters-and-facilities%2Farmstrong%2Fnasa-partners-explore-sustainable-fuels-effects-on-aircraft-contrails%2F\" aria-label=\"Share on LinkedIn.\">\n\t\t\t\t\t\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 24 24\" aria-hidden=\"true\"><path d=\"M4.98 3.5c0 1.381-1.11 2.5-2.48 2.5s-2.48-1.119-2.48-2.5c0-1.38 1.11-2.5 2.48-2.5s2.48 1.12 2.48 2.5zm.02 4.5h-5v16h5v-16zm7.982 0h-4.968v16h4.969v-8.399c0-4.67 6.029-5.052 6.029 0v8.399h4.988v-10.131c0-7.88-8.922-7.593-11.018-3.714v-2.155z\"\/><\/svg>\n\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t<\/li>\n\t\t\t\t\t\t<li class=\"social-icon social-icon-rss\">\n\t\t\t\t\t\t\t<a href=\"\/feed\/\" aria-label=\"Subscribe to RSS feed.\">\n\t\t\t\t\t\t\t\t<svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 800 800\" aria-hidden=\"true\"><path d=\"M493 652H392c0-134-111-244-244-244V307c189 0 345 156 345 345zm71 0c0-228-188-416-416-416V132c285 0 520 235 520 520z\"\/><circle cx=\"219\" cy=\"581\" r=\"71\"\/><\/svg>\n\t\t\t\t\t\t\t<\/a>\n\t\t\t\t\t\t<\/li>\n\t\t\t\t\t<\/ul>\n\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\t<\/div>\n\t\t<div class=\"grid-col-12 desktop:grid-col-5 padding-right-4 margin-bottom-5 desktop:margin-bottom-0\">\n\t\t\t<div class=\"padding-top-3 border-top-1px border-color-carbon-black\">\n\t\t\t\t<div class=\"margin-bottom-2\">\n\t\t\t\t\t<h2 class=\"heading-14\">Details<\/h2>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"grid-row margin-bottom-3\">\n\t\t\t\t\t<div class=\"grid-col-4\">\n\t\t\t\t\t\t<div class=\"subheading\">Last Updated<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t\t<div class=\"grid-col-8\">Nov 14, 2023<\/div>\n\t\t\t\t<\/div>\n\t\t\t<div class=\"grid-row margin-bottom-3\"><div class=\"grid-col-4\"><div class=\"subheading\">Editor<\/div><\/div><div class=\"grid-col-8\">Ryan M.
