Originally designed for five flights, Ingenuity ultimately completed 72 before crashing in January 2024.\nIngenuity's carbon-fiber blades spun at roughly 2,700 rpm, already about 10 times faster than passenger helicopters on Earth. NASA said engineers intentionally avoided supersonic rotor speeds because they did not know whether the blades could survive the stress.\nDon't Miss:\n\"If Chuck Yeager were here, he'd tell you things can get squirrely around Mach 1,\" NASA rotor test lead Jaakko Karras said, referring to the first pilot to break the sound barrier.\nNASA said engineers lined parts of the test chamber with sheet metal because they were uncertain whether the blades would survive the experiment intact.\n\"We want more performance from our next-gen Mars aircraft,\" Karras said after rotor tips reached Mach 1.08 inside a Mars simulation chamber.\nSee Also: This Under-$1 Pre-IPO AI Company Is Still Open to Retail Investors — Learn More\nThe tests involved larger rotor blades designed for NASA's proposed SkyFall Mars mission, which could launch as soon as 2028. NASA said it plans to send three helicopters capable of carrying heavier payloads than Ingenuity.\nThe higher rotor speeds generated roughly 30% more lift, potentially allowing future helicopters to carry larger batteries and heavier scientific instruments.\nNASA Ames Research Center aerodynamicist Shannah Withrow-Maser said in the statement that the team originally expected the aircraft might only reach Mach 1.05, but test runs ultimately hit Mach 1.08. She added that researchers are still analyzing the data and believe additional thrust gains may still be possible. \"These next-gen helicopters are going to be amazing,\" she said.\nFuture Mars helicopters are expected to operate far more independently than Ingenuity. NASA said future rotorcraft may communicate directly with Earth or through orbiting satellites while carrying instruments designed to search for ice beneath the Martian surface.\nNASA is also developing Dragonfly, a much larger rotorcraft designed to explore Saturn's moon Titan. The agency said breaking the sound barrier without damaging the hardware moves scientists one step closer to a new era of planetary exploration.\nRead Next: \nRad AI\nImmersed\nConnect Invest\nrHealth\nrHealth is building a space-tested diagnostics platform designed to bring lab-quality blood testing closer to patients in minutes rather than weeks. Originally validated in collaboration with NASA for use aboard the International Space Station, the technology is now being adapted for at-home and point-of-care settings to address widespread delays in diagnostic access.\nBacked by institutions including NASA and the NIH, rHealth is targeting the large global diagnostics market with a multi-test platform and a model built around devices, consumables, and software. With FDA registration in progress, the company is positioning itself as a potential shift toward faster, more decentralized healthcare testing.\nArrived\nMasterworks\nLightstone\nAdviserMatch\nAccredited Debt Relief\nImage: Shutterstock\nTo add Benzinga News as your preferred source on Google, click here.","kind":"highlight","is_publish_news":true,"is_publish_highlight":false,"is_publish_live":false,"is_publish_wemedia":null,"editions":null,"column":"","sentiment":"0","news_tag":"","news_rank":0,"isVideo":false,"video":null,"symbols":[],"gpt_button":0,"need_auth":false,"need_login_tip":false,"code":"91000000","status":"200"},"commentList":[],"isCommentEnd":true,"newsSizeData":{"likeSize":0,"commentSize":0,"repostSize":0,"favoriteSize":0,"likeStatus":false,"favoriteStatus":false},"APP":{"userAgent":"Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; ClaudeBot/1.0; +claudebot@anthropic.com)","isDev":false,"isTTM":true,"tenantId":"TBGLOBAL","deviceId":"web-server-community-laohu8-v3","version":"4.42.2","shortVersion":"4.42.2","platform":"web","vendor":"web","appName":"ttm","isIOS":false,"isAndroid":false,"isTiger":false,"isTHS":false,"isWeiXin":false,"isWeiXinMini":false,"isWeiBo":false,"isQQ":false,"isBaiduSwan":false,"isBaiduBox":false,"isDingTalk":false,"isToutiao":false,"isOnePlus":false,"isHuaWei":false,"isXiaomi":false,"isXiaomiWebView":false,"isOppo":false,"isVivo":false,"isSamsung":false,"isMobile":false},"href":"/m/news/2637829369","isCrawlerRequest":true}
