NASA’s home for experimental flight is welcoming more flyers to its already high-performing fleet as it continues to support science and aeronautics test missions – continuing the legacy of pioneers like Neil Armstrong.

NASA’s Armstrong Flight Research Center in Edwards, California, added multiple aircraft this year: two F-15s supersonic jets, a Pilatus PC-12 utility plane, and a T-34 turboprop trainer, which the center will use to support the agency’s advancement of aerospace research.

Throughout the center’s history, pilots have flown everything from large aircraft like the 747 Shuttle Carrier Aircraft and rocket-powered airplanes like the X-15 to high-speed repurposed fighter jets like the F-18. And after almost 80 years, flight research is still going strong in the desert today.

“Armstrong has a rich history of flight research, but it’s the multidimensional skills of the people we have here, and the knowledge they’ve built to handle very unique aircraft maintenance and modifications, that stands out,” said Darren Cole, capabilities manager for the Flight Demonstrations and Capabilities project at NASA Armstrong.

The center plays a pivotal role in worldwide airborne science missions, flying scientists and equipment from NASA, other government agencies, industry, and academia to collect measurements such as air pollution levels, glacier melt trends, and wildland fire mapping.

Scientists can manage experiments in real time aboard flying laboratories like the NASA ER-2, to collect important data with the help of Armstrong’s pilots and airborne science team.

“We all come together to make the science happen,” said Matt Berry, airborne research platforms branch chief at NASA Armstrong. “It is the agility of the Armstrong team that allows us to collaborate with scientists, get their equipment onboard, and to fly them to areas where they need to collect data.”

The center sits on Rogers Dry Lake, a 44-square-mile slat flat area used for aviation research and test operations. Rogers and the adjacent Rosamond Dry Lake have seen everything from space shuttle landings to emergency test flight recoveries. The Rogers lakebed continues to serve as an important piece of Armstrong’s test missions.

For NASA Armstrong, it all started with the first attempt by a human to fly faster than the speed of sound in the Bell X-1. In 1946, 13 employees from NASA’s predecessor agency, the National Advisory Committee for Aeronautics (NACA), arrived at what was then known as Muroc Army Airfield to prepare for the X-1 tests. A year later, NACA’s Muroc Flight Test Unit was established as a permanent facility at the airfield.

The center has gone by several names over the years, most recently changing from NASA’s Dryden Flight Research Center to NASA Armstrong in 2014. But its legacy has never shifted: The Bell X-1E, the last of the X-1 series of aircraft, now sits in front of NASA Armstrong, welcoming the newest test pilots, engineers, scientists, explorers, and dreamers. And they’re using the aircraft of today to break new barriers.

“I don’t think there is another place in the world with a more diverse fleet of aircraft. We have everything from a low-altitude powered glider to ER-2s, which are flying at high altitudes, and a multitude of aircraft in between,” Cole said.

From sourcing rare components to machining custom parts in-house, NASA Armstrong’s teams transform these aircraft into research workhorses. The center continues its crucial role in leading aeronautics testing, Earth Science research, and supporting the Department of War.

The Republic of Paraguay signed the Artemis Accords on Thursday during a ceremony in Asunción, becoming the latest nation to commit to the shared principles guiding civil space exploration.

“Today, I am proud to welcome Paraguay as the 67th signatory to the Artemis Accords,” said NASA Administrator Jared Isaacman. “They join an ever-growing coalition of like-minded nations committed to the peaceful, transparent, and responsible exploration of space. Established by President Trump in his first term, the Artemis Accords provided the principles for how we explore the Moon, Mars, and beyond. Now, with his national space policy, we are putting the Artemis Accords into practice with our Moon Base. We are creating opportunities for all Artemis Accords signatories, including Paraguay, to join us on the lunar surface and advance our shared objectives in this next era of exploration.”

U.S. Embassy Asunción Chargé d’Affaires ad interim Aaron Pratt shared Isaacman’s remarks during the ceremony. Minister President of the Paraguayan Space Agency Osvaldo Almirón Riveros signed on behalf of Paraguay.

“The signing of the Artemis Accords represents a historic milestone for Paraguay and reflects our commitment to international cooperation, the peaceful use of outer space, scientific development, and the advancement of national space capabilities,” said Almirón Riveros. “This step strengthens Paraguay’s position within the global space community and opens new opportunities for research, innovation, and sustainable development.”

The Paraguayan Space Agency was established in 2014 and has worked to develop capabilities in satellite technology and Earth observation, including with international partners. Its first satellite, GuaraníSat‑1, launched from the International Space Station in 2021. The agency now is preparing to launch its second satellite, GuaraníSat‑2, in October aboard a Falcon 9 from Vandenberg Space Force Base in California. The mission was developed with collaborators from NASA’s Jet Propulsion Laboratory and other partners.

In 2020, the United States, led by NASA and the U.S. State Department, joined with seven other founding nations to establish the Artemis Accords, responding to the growing interest in lunar activities by both governments and private companies. The Artemis Accords introduced the first set of practical principles aimed at enhancing the safety and coordination between like-minded nations as they explore the Moon, Mars, and beyond.  

Signing the Artemis Accords means committing to explore peaceably and transparently, to render aid to those in need, to enable access to scientific data that all of humanity can learn from, to ensure activities do not interfere with those of others, and to preserve historically significant sites and artifacts by developing best practices for space exploration for the benefit of all. 

More countries are expected to sign the Artemis Accords in the months and years ahead, as NASA continues its work to establish a safe, peaceful, and prosperous future in space.

The rotor blades that will carry NASA’s next-generation helicopters to new Martian heights broke the sound barrier during March tests at NASA’s Jet Propulsion Laboratory in Southern California. Data from the tests, which took place in a special chamber that can simulate environmental conditions on the Red Planet, indicate that the fastest traveling part of the rotor blade, the tips, can be accelerated beyond Mach 1 without breaking apart. Data gathered from 137 test runs will enable engineers to design aircraft capable of carrying heavier payloads, including science instruments.

“NASA had a great run with the Ingenuity Mars Helicopter, but we are asking these next-generation aircraft to do even more at the Red Planet,” said Al Chen, Mars Exploration Program manager at JPL. “That’s not an easy ask. While everything about Mars is hard, flying there is just about the hardest thing you can do. That’s because its atmosphere is so incredibly thin that it is hard to generate lift, and yet Mars has significant gravity.”

Ingenuity, which performed the first powered, controlled flight on another world just over five years ago on April 19, 2021, was a trailblazing technology demonstration that did not carry science instruments. The agency’s recently announced SkyFall project and other potential future Mars aircraft will be capable of carrying payloads — including science instruments and sensors — to collect data in support of future human and robotic missions, leveraging the advantages that come with low-altitude aerial exploration.

Need for speed

In the fast-moving world of rotors, more thrust comes from a quicker spin or a larger diameter. Although this axiom holds true on Earth, engineers designing aircraft for the Red Planet must be much more aggressive. Because the Mars atmosphere is only 1% as dense as Earth’s, maximizing thrust requires pushing blade tips toward the speed of sound to achieve significant lift. While small-diameter rotors on Earth can also rotate at thousands of revolutions per minute, they have more air molecules to push and don’t need to approach the sonic edge.

The Ingenuity flight team never allowed the rotational speed of their composite-skinned foam rotors to exceed 2,700 rpm during the helicopter’s 72 flights at Mars for two reasons: to avoid the unpredictable physics of the sound barrier and to make sure that an unexpected gust of wind (from a dust devil, for instance) wouldn’t send the rotor tips over the sonic edge.

“If Chuck Yeager were here, he’d tell you things can get squirrely around Mach 1,” said JPL’s Jaakko Karras, the rotor test lead. “With that in mind, we planned Ingenuity’s flights to keep the rotor blade tips at Mach 0.7 with no wind so that if we encountered a Martian headwind while in flight, the rotor tips wouldn’t go supersonic. But we want more performance from our next-gen Mars aircraft. We needed to know that our rotors could go faster safely.”

While Mach 1 on Earth at sea level is approximately 760 mph (1,223 kph), the speed of sound on Mars is significantly slower — roughly 540 mph (869 kph) — due to the planet’s thin, cold, carbon-dioxide-rich atmosphere.

Blade-proof chamber

To begin evaluating the rotors, which were developed and manufactured by AeroVironment in Simi Valley, California, Karras and his team mounted a three-bladed rotor that could be used in future Mars helicopter designs inside the historic 25-Foot Space Simulator at JPL. They evacuated the air and replaced it with just enough carbon dioxide to match the Martian atmosphere, then blasted the rotor with wind as it spun at increasing speeds.

The test engineers had taken the precaution of lining part of the chamber with sheet metal in case the blades broke apart during the supersonic experiment. From a control room a few yards away from the chamber, the team watched displays showing data and a view inside the chamber as the rpm climbed as high as 3,750. At that rate, the tips were traveling at Mach 0.98. Then the engineers activated a fan inside the chamber that pelted the rotors with headwinds. After each run, they increased in wind velocity for the next run.

The team pushed rotor tip speeds to Mach 1.08, boosting the Mars vehicle’s lift capability by 30%. This breakthrough allows future missions to support heavier scientific payloads, including advanced sensors and larger batteries for extended flight.

Next the team tried their luck with the two-bladed SkyFall rotor. Because it is slightly longer than the three-bladed version, only 3,570 rpm was needed to achieve the same near-supersonic speed at the rotor tips prior to introducing the headwinds.

“The successful testing of these rotors was a major step toward proving the feasibility of flight in more demanding environments, which is key for next-gen vehicles,” said Shannah Withrow-Maser, an aerodynamicist from NASA’s Ames Research Center in Silicon Valley and member of the test team. “We thought we’d be lucky to hit Mach 1.05, and we reached Mach 1.08 on our last runs. We’re still digging into the data, and there may be even more thrust on the table. These next-gen helicopters are going to be amazing.”

The SkyFall mission design team has incorporated the test team’s findings into the performance specifications. Inspired by Ingenuity, the only rotorcraft to fly on another planet to date, SkyFall is designed to carry three next-gen Mars helicopters to the Red Planet in December 2028.
