The flight began at 11:08 a.m. Pacific Time and lasted 81 minutes, according to the release.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;X-59 is getting ready for its quiet supersonic debut. Since the aircraft&#8217;s first flight on Oct. 28, 2025, the team has made tremendous progress, flying 16 times in the last 90 days and getting into a steady test rhythm. In the coming days, we expect to take the next step and push to Mach 1.4,&#8221; NASA Administrator Jared Isaacman said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Over the last several months, the X-59 has been undergoing a series of flight tests at a wide range of speeds and altitudes, which represents the first phase of the aircraft&#8217;s flight-test program that focuses on performance evaluation and involves chase plane monitoring, said the release.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The next phase of testing will focus on the X-59&#8217;s sound profile to verify its quiet thump capability, it said.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The X-59 aircraft is designed to fly at supersonic speeds while creating only a quiet thump instead of a loud sonic boom. It is the centerpiece of NASA&#8217;s Quesst mission, which aims to demonstrate quiet supersonic flight and help enable commercial supersonic flight over land worldwide, said the release.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"2700\" height=\"1800\" src=\"https:\/\/cdn.igihe.com\/en\/2026\/06\/Lockheed_Martin_X59_First_Flight.jpg\" alt=\"\" class=\"wp-image-2000114723\"\/><figcaption class=\"wp-element-caption\">NASA&#8217;s experimental X-59 aircraft completed its first supersonic flight on Friday.<\/figcaption><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>NASA&#8217;s experimental X-59 aircraft completed its first supersonic flight on Friday, marking a major milestone in the development of the agency&#8217;s quiet supersonic technology.<\/p>\n","protected":false},"author":3,"featured_media":2000114723,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[9],"tags":[],"byline":[235],"hashtag":[],"class_list":["post-2000114722","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-science-technology","byline-xinhua"],"bylines":[{"id":235,"name":"Xinhua","slug":"xinhua","description":"","image":{"id":0,"url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&f=y&r=g","alt":"Default avatar","title":"Default avatar","caption":"","mime_type":"image\/jpeg","sizes":[]},"user_id":80}],"contributors":[{"id":235,"name":"Xinhua","slug":"xinhua","description":"","image":{"id":0,"url":"https:\/\/secure.gravatar.com\/avatar\/?s=96&d=mm&f=y&r=g","alt":"Default avatar","title":"Default avatar","caption":"","mime_type":"image\/jpeg","sizes":[]},"user_id":80}],"featured_image":{"id":2000114723,"url":"https:\/\/cdn.igihe.com\/en\/2026\/06\/Lockheed_Martin_X59_First_Flight.jpg","alt":"","caption":"NASA's experimental X-59 aircraft completed its first supersonic flight on Friday.","mime_type":"image\/jpeg","width":2700,"height":1800,"sizes":{"thumbnail":{"url":"https:\/\/cdn.igihe.com\/en\/2026\/06\/Lockheed_Martin_X59_First_Flight.jpg","width":2700,"height":1800},"medium":{"url":"https:\/\/cdn.igihe.com\/en\/2026\/06\/Lockheed_Martin_X59_First_Flight.jpg","width":2700,"height":1800},"medium_large":{"url":"https:\/\/cdn.igihe.com\/en\/2026\/06\/Lockheed_Martin_X59_First_Flight.jpg","width":2700,"height":1800},"large":{"url":"https:\/\/cdn.igihe.com\/en\/2026\/06\/Lockheed_Martin_X59_First_Flight.jpg","width":2700,"height":1800},"full":{"url":"https:\/\/cdn.igihe.com\/en\/2026\/06\/Lockheed_Martin_X59_First_Flight.jpg","width":2700,"height":1800}}},"_links":{"self":[{"href":"https:\/\/new.igihe.com\/english\/wp-json\/wp\/v2\/posts\/2000114722","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/new.igihe.com\/english\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/new.igihe.com\/english\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/new.igihe.com\/english\/wp-json\/wp\/v2\/users\/3"}],"replies":[{"embeddable":true,"href":"https:\/\/new.igihe.com\/english\/wp-json\/wp\/v2\/comments?post=2000114722"}],"version-history":[{"count":1,"href":"https:\/\/new.igihe.com\/english\/wp-json\/wp\/v2\/posts\/2000114722\/revisions"}],"predecessor-version":[{"id":2000114724,"href":"https:\/\/new.igihe.com\/english\/wp-json\/wp\/v2\/posts\/2000114722\/revisions\/2000114724"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/new.igihe.com\/english\/wp-json\/wp\/v2\/media\/2000114723"}],"wp:attachment":[{"href":"https:\/\/new.igihe.com\/english\/wp-json\/wp\/v2\/media?parent=2000114722"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/new.igihe.com\/english\/wp-json\/wp\/v2\/categories?post=2000114722"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/new.igihe.com\/english\/wp-json\/wp\/v2\/tags?post=2000114722"},{"taxonomy":"byline","embeddable":true,"href":"https:\/\/new.igihe.com\/english\/wp-json\/wp\/v2\/byline?post=2000114722"},{"taxonomy":"hashtag","embeddable":true,"href":"https:\/\/new.igihe.com\/english\/wp-json\/wp\/v2\/hashtag?post=2000114722"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
