The flight occurred Sept 16. NASA\/JPL-Caltech\/ASU\/MSSS<\/figcaption><\/figure>\n\n\n\n<p><em>Engineers will go beyond the ends of the Earth to find more performance for future Mars helicopters.<\/em><\/p>\n\n\n\n<p>For the first time in history, two planets have been home to testing future aircraft designs. On this world, a new rotor that could be used with next-generation Mars helicopters was recently tested at NASA\u2019s Jet Propulsion Laboratory in Southern California, spinning at near-supersonic speeds (0.95 Mach). Meanwhile, the agency\u2019s Ingenuity Mars Helicopter has achieved new altitude and airspeed records on the Red Planet in the name of experimental flight testing.<\/p>\n\n\n\n<p>\u201cOur next-generation Mars helicopter testing has literally had the best of both worlds,\u201d said Teddy Tzanetos, Ingenuity\u2019s project manager and manager for the Mars Sample Recovery Helicopters. \u201cHere on Earth, you have all the instrumentation and hands-on immediacy you could hope for while testing new aircraft components. On Mars, you have the real off-world conditions you could never truly re-create here on Earth.\u201d That includes a whisper-thin atmosphere and significantly less gravity than on Earth.<\/p>\n\n\n\n<p>The next-generation carbon fiber rotor blades being tested on Earth are almost 4 inches (more than 10 centimeters) longer than Ingenuity\u2019s, with greater strength and a different design. NASA thinks these blades could enable bigger, more capable Mars helicopters. The challenge is, as the blade tips approach supersonic speeds, vibration-causing turbulence can quickly get out of hand.<\/p>\n\n\n\n<p>To find a space big enough to create a Martian atmosphere on Earth, engineers looked to JPL\u2019s 25-foot wide, 85-foot-tall (8-meter-by-26-meter) <a href=\"https:\/\/www.nasa.gov\/setmo\/facilities\/25-foot-space-simulator\/\">space simulator<\/a> \u2013 a place where <a href=\"https:\/\/www.jpl.nasa.gov\/missions\/surveyor-1\" rel=\"noopener\">Surveyor<\/a>, <a href=\"https:\/\/voyager.jpl.nasa.gov\/\" rel=\"noopener\">Voyager<\/a>, and <a href=\"https:\/\/www.jpl.nasa.gov\/missions\/cassini-huygens\" rel=\"noopener\">Cassini<\/a> got their first taste of space-like environments. For three weeks in September, a team monitored sensors, meters, and cameras as the blades endured run after run at ever-higher speeds and greater pitch angles.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-video is-provider-youtube wp-block-embed-youtube\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Testing Next-Generation Mars Helicopter Rotors\" width=\"640\" height=\"360\" src=\"https:\/\/www.youtube.com\/embed\/zjt3DMNqtus?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen><\/iframe>\n<\/div><figcaption class=\"wp-element-caption\">A dual rotor system for the next generation of Mars helicopters is tested in the 25-Foot Space Simulator at NASA\u2019s Jet Propulsion Laboratory on Sept.15. Longer and stronger than those used on the Ingenuity Mars Helicopter, the carbon-fiber blades reached near-supersonic speeds during testing. NASA\/JPL-Caltech<\/figcaption><\/figure>\n\n\n\n<p>\u201cWe spun our blades up to 3,500 rpm, which is 750 revolutions per minute faster than the Ingenuity blades have gone,\u201d said Tyler Del Sesto, Sample Recovery Helicopter deputy test conductor at JPL. \u201cThese more efficient blades are now more than a hypothetical exercise. They are ready to fly.\u201d<\/p>\n\n\n\n<p>At around the same time, and about 100 million miles (161 million kilometers) away, Ingenuity was being commanded to try things the Mars Helicopter team never imagined they would get to do. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Fourth Rock Flight Testing<\/strong><\/h2>\n\n\n\n<p>Ingenuity was originally slated to fly no more than five times. With its <a href=\"https:\/\/www.nasa.gov\/news-release\/nasas-ingenuity-mars-helicopter-succeeds-in-historic-first-flight\/\">first flight<\/a> entering the mission <a href=\"https:\/\/www.jpl.nasa.gov\/images\/pia24794-ingenuity-logbook-entries\" rel=\"noopener\">logbook<\/a> more than two-and-a-half years ago, the helicopter has exceeded its planned 30-day mission by 32 times and has flown 66 times. Every time Ingenuity goes airborne, it covers new ground, offering a <a href=\"https:\/\/mars.nasa.gov\/news\/9043\/nasas-ingenuity-helicopter-captures-a-mars-rock-feature-in-3d\/\" rel=\"noopener\">perspective<\/a> no previous planetary mission could achieve. But lately, Team Ingenuity has been taking their solar-powered rotorcraft out for a spin like never before.<\/p>\n\n\n\n<p>\u201cOver the past nine months, we have doubled our max airspeed and altitude, increased our rate of vertical and horizontal acceleration, and even learned to land slower,\u201d said Travis Brown, Ingenuity\u2019s chief engineer at JPL. \u201cThe envelope expansion provides invaluable data that can be used by mission designers for future Mars helicopters.\u201d<\/p>\n\n\n\n<p>Limited by available energy and motor-temperature considerations, Ingenuity flights usually last around two to three minutes. Although the helicopter can cover more ground in a single flight by flying faster, flying too fast can confuse the onboard navigation system. The system uses a camera that recognizes rocks and other surface features as they move through its field of view. If those features whiz by too fast, the system can lose its way.<\/p>\n\n\n\n<p>So, to achieve a higher maximum ground speed, the team sends commands for Ingenuity to fly at higher altitudes (instructions are sent to the helicopter before each flight), which keeps features in view longer. <a href=\"https:\/\/mars.nasa.gov\/technology\/helicopter\/status\/485\/flight-61-preview-by-the-numbers\/\" rel=\"noopener\">Flight 61<\/a> established a new altitude record of 78.7 feet (24 meters) as it checked out Martian wind patterns. With <a href=\"https:\/\/mars.nasa.gov\/technology\/helicopter\/status\/487\/flight-62-preview-by-the-numbers\/\" rel=\"noopener\">Flight 62<\/a> Ingenuity set a speed record of 22.3 mph (10 meters per second) \u2013 and <a href=\"https:\/\/mars.nasa.gov\/mars2020\/multimedia\/raw-images\/HSF_0940_0750380739_812ECM_N0620001HELI00006_000085J\" rel=\"noopener\">scouted a location<\/a> for the Perseverance rover\u2019s science team.<\/p>\n\n\n\n<p>The team has also been experimenting with Ingenuity\u2019s landing speed. The helicopter was designed to contact the surface at a relatively brisk 2.2 mph (1 mps) so its onboard sensors could easily confirm touchdown and shut down the rotors before it could bounce back into the air. A helicopter that lands more slowly could be designed with lighter landing gear. So, on Flights 57, 58, and 59 they gave it a whirl, demonstrating Ingenuity could land at speeds 25% slower than the helicopter was originally designed to land at.<\/p>\n\n\n\n<p>All this Martian <a href=\"https:\/\/history.nasa.gov\/x1\/chuck.html\" rel=\"noopener\">Chuck Yeager<\/a>-ing is not over. In December, after <a href=\"https:\/\/www.jpl.nasa.gov\/news\/nasas-mars-fleet-will-still-conduct-science-while-lying-low\" rel=\"noopener\">solar conjunction<\/a>, Ingenuity is expected to perform two high-speed flights during which it will execute a special set of pitch-and-roll angles designed to measure its performance.<\/p>\n\n\n\n<p>\u201cThe data will be extremely useful in fine-tuning our aero-mechanical models of how rotorcraft behave on Mars,\u201d said Brown. \u201cOn Earth, such testing is usually performed in the first few flights. But that\u2019s not where we\u2019re flying. You have to be a little more careful when you\u2019re operating that far away from the nearest repair shop, because you don\u2019t get any do-overs.\u201d<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>More About Ingenuity<\/strong><\/h2>\n\n\n\n<p>Ingenuity began its life at Mars as a technology demonstration. It <a href=\"https:\/\/mars.nasa.gov\/news\/8923\/nasas-ingenuity-mars-helicopter-succeeds-in-historic-first-flight\/\" rel=\"noopener\">first flew<\/a> on April 19, 2021, hovering 10 feet (3 meters) for 30 seconds. Four more flights in as many weeks added 499 seconds and saw the helicopter flying horizontally over the surface for 1,171 feet (357 meters). After proving flight was possible on Mars, Ingenuity entered an <a href=\"https:\/\/mars.nasa.gov\/news\/8936\/nasas-ingenuity-helicopter-to-begin-new-demonstration-phase\/\" rel=\"noopener\">operations demonstration<\/a> phase in May 2021 to show how aerial scouting could benefit future exploration of Mars and other worlds.<\/p>\n\n\n\n<p>The Ingenuity Mars Helicopter was built by JPL, which also manages the project for NASA Headquarters. It is supported by NASA\u2019s Science Mission Directorate. NASA\u2019s Ames Research Center in California\u2019s Silicon Valley and NASA\u2019s Langley Research Center in Hampton, Virginia, provided significant flight performance analysis and technical assistance during Ingenuity\u2019s development. AeroVironment Inc., Qualcomm, and SolAero also provided design assistance and major vehicle components. Lockheed Space designed and manufactured the <a href=\"https:\/\/mars.nasa.gov\/resources\/25081\/testing-the-mars-helicopter-delivery-system\/\" rel=\"noopener\">Mars Helicopter Delivery
