El equipo detrás del X-59 de la NASA completó en marzo otra prueba crítica en tierra, garantizando que el silencioso avión supersónico será capaz de mantener una velocidad específica durante su funcionamiento. Esta prueba, conocida como mantenimiento automático de velocidad del motor, es el más reciente marcador de progreso a medida que el X-59 se acerca a su primer vuelo este año.
“El mantenimiento automático de la velocidad del motor es básicamente la versión de control de crucero de la aeronave,” explicó Paul Dees, jefe adjunto de propulsión de la NASA del X-59 en el Centro de Investigación de Vuelo Armstrong de la agencia en Edwards, California. “El piloto activa el control de velocidad a su velocidad actual y luego puede aumentarla o ajustarla gradualmente según sea necesario.”
El equipo del X-59 ya había realizado una prueba similar en el motor, pero sólo como un sistema aislado. La prueba de marzo verificó que la retención de velocidad funciona correctamente tras su integración en la aviónica de la aeronave.
“Necesitábamos verificar que el mantenimiento automático de velocidad funcionara no sólo dentro del propio motor, sino como parte de todo el sistema del avión,” explicó Dees. “Esta prueba confirmó que todos los componentes – software, enlaces mecánicos y leyes de control – funcionan juntos según lo previsto.”
El éxito de la prueba confirmó la habilidad de la aeronave para controlar la velocidad con precisión, lo cual será muy invaluable durante el vuelo. Esta capacidad aumentará la seguridad de los pilotos, permitiéndoles enfocarse en otros aspectos críticos de la operación de vuelo.
“El piloto va a estar muy ocupado durante el primer vuelo, asegurándose de que la aeronave sea estable y controlable,” dijo Dees. “Al tener la función del mantenimiento automático de velocidad, de reduce parte de esa carga de trabajo, lo que hace que el primer vuelo sea mucho más seguro.”
Inicialmente el equipo tenía planeado comprobar el mantenimiento automático de velocidad como parte de una próxima serie de pruebas en tierra donde alimentarían la aeronave con un sólido conjunto de datos para verificar su funcionalidad tanto en condiciones normales como de fallo, conocidas como pruebas de pájaro de aluminio (una estructura que se utiliza para probar los sistemas de una aeronave en un laboratorio, simulando un vuelo real). Sin embargo, el equipo se dio cuenta que había una oportunidad de probarlo antes.
“Fue un objetivo de oportunidad,” dijo Dees. “Nos dimos cuenta de que estábamos listos para probar el mantenimiento automático de velocidad del motor por separado mientras otros sistemas continuaban con la finalización de su software. Si podemos aprender algo antes, siempre es mejor.”
Con cada prueba exitosa, el equipo integrado de la NASA y Lockheed Martin acerca el X-59 al primer vuelo, y hacer historia en la aviación a través de su tecnología supersónica silenciosa.

From left are Mission Specialist Kimiya Yui from JAXA (Japan Aerospace Exploration Agency), Commander NASA astronaut Zena Cardman, Mission Specialist Oleg Platonov of Roscosmos, and Pilot NASA astronaut Mike Fincke.Credit: NASA As part of NASA’s SpaceX Crew-11 mission, four crew members from three space agencies will launch in the coming months to the International Space Station for a long-duration science expedition aboard the orbiting laboratory.
NASA astronauts Commander Zena Cardman and Pilot Mike Fincke, JAXA (Japan Aerospace Exploration Agency) astronaut Mission Specialist Kimiya Yui, and Roscosmos cosmonaut Mission Specialist Oleg Platonov will join crew members aboard the space station no earlier than July 2025.
The flight is the 11th crew rotation with SpaceX to the station as part of NASA’s Commercial Crew Program. The crew will conduct scientific investigations and technology demonstrations to help prepare humans for future missions to the Moon, as well as benefit people on Earth.
Cardman previously was assigned to NASA’s SpaceX Crew-9 mission, and Fincke previously was assigned to NASA’s Boeing Starliner-1 mission. NASA decided to reassign the astronauts to Crew-11 in overall support of planned activities aboard the International Space Station. Cardman carries her experience training as a commander on Dragon spacecraft, and Fincke brings long-duration spaceflight experience to this crew complement.
Selected as a NASA astronaut in 2017, Cardman will conduct her first spaceflight. The Williamsburg, Virginia, native holds a bachelor’s degree in Biology and a master’s in Marine Sciences from the University of North Carolina at Chapel Hill. At the time of selection, she had begun pursuing a doctorate in Geosciences. Cardman’s research in geobiology and geochemical cycling focused on subsurface environments, from caves to deep sea sediments. Since completing initial training, Cardman has supported real-time station operations and lunar surface exploration planning.
This will be Fincke’s fourth trip to the space station, having logged 382 days in space and nine spacewalks during Expedition 9 in 2004, Expedition 18 in 2008, and STS-134 in 2011, the final flight of space shuttle Endeavour. Throughout the past decade, Fincke has applied his expertise to NASA’s Commercial Crew Program, advancing the development and testing of the SpaceX Dragon and Boeing Starliner toward operational certification. The Emsworth, Pennsylvania, native is a distinguished graduate of the United States Air Force Test Pilot School and holds bachelors’ degrees from the Massachusetts Institute of Technology, Cambridge, in both Aeronautics and Astronautics, as well as Earth, Atmospheric and Planetary Sciences. He also has a master’s degree in Aeronautics and Astronautics from Stanford University in California. Fincke is a retired U.S. Air Force colonel with more than 2,000 flight hours in more than 30 different aircraft.
With 142 days in space, this will be Yui’s second trip to the space station. After his selection as a JAXA astronaut in 2009, Yui flew as a flight engineer for Expedition 44/45 and became the first Japanese astronaut to capture JAXA’s H-II Transfer Vehicle. In addition to constructing a new experimental environment aboard Kibo, he conducted a total of 21 experiments for JAXA. In November 2016, Yui was assigned as chief of the JAXA Astronaut Group. He graduated from the School of Science and Engineering at the National Defense Academy of Japan in 1992. He later joined the Air Self-Defense Force at the Japan Defense Agency (currently Ministry of Defense). In 2008, Yui joined the Air Staff Office at the Ministry of Defense as a lieutenant colonel.
The Crew-11 mission will be Platonov’s first spaceflight. Before his selection as a cosmonaut in 2018, Platonov earned a degree in Engineering from Krasnodar Air Force Academy in Aircraft Operations and Air Traffic Management. He also earned a bachelor’s degree in State and Municipal Management in 2016 from the Far Eastern Federal University in Vladivostok, Russia. Assigned as a test cosmonaut in 2021, he has experience in piloting aircraft, zero gravity training, scuba diving, and wilderness survival.
For more than two decades, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and demonstrating new technologies, making research breakthroughs not possible on Earth. The station is a critical testbed for NASA to understand and overcome the challenges of long-duration spaceflight and to expand commercial opportunities in low Earth orbit. As commercial companies focus on providing human space transportation services and destinations as part of a robust low Earth orbit economy, NASA’s Artemis campaign is underway at the Moon, where the agency is preparing for future human exploration of Mars.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s X-59 quiet supersonic research aircraft sits on a ramp at Lockheed Martin Skunk Works in Palmdale, California, during sunset. The one-of-a-kind aircraft is powered by a General Electric F414 engine, a variant of the engines used on F/A-18 fighter jets. The engine is mounted above the fuselage to reduce the number of shockwaves that reach the ground. The X-59 is the centerpiece of NASA’s Quesst mission, which aims to demonstrate quiet supersonic flight and enable future commercial travel over land – faster than the speed of sound.Lockheed Martin Corporation/Garry Tice The team behind NASA’s X-59 completed another critical ground test in March, ensuring the quiet supersonic aircraft will be able to maintain a specific speed during operation. The test, known as engine speed hold, is the latest marker of progress as the X-59 nears first flight this year.
“Engine speed hold is essentially the aircraft’s version of cruise control,” said Paul Dees, NASA’s X-59 deputy propulsion lead at the agency’s Armstrong Flight Research Center in Edwards, California. “The pilot engages speed hold at their current speed, then can adjust it incrementally up or down as needed.”
The X-59 team had previously conducted a similar test on the engine – but only as an isolated system. The March test verified the speed hold functions properly after integration into the aircraft’s avionics.
“We needed to verify that speed hold worked not just within the engine itself but as part of the entire aircraft system.” Dees explained. “This test confirmed that all components – software, mechanical linkages, and control laws – work together as intended.”
The successful test confirmed the aircraft’s ability to precisely control speed, which will be invaluable during flight. This capability will increase pilot safety, allowing them to focus on other critical aspects of flight operation.
“The pilot is going to be very busy during first flight, ensuring the aircraft is stable and controllable,” Dees said. “Having speed hold offload some of that workload makes first flight that much safer.”
The team originally planned to check the speed hold as part of an upcoming series of ground test trials where they will feed the aircraft with a robust set of data to verify functionality under both normal and failure conditions, known as aluminum bird tests. But the team recognized a chance to test sooner.
“It was a target of opportunity,” Dees said. “We realized we were ready to test engine speed hold separately while other systems continued with finalizing their software. If we can learn something earlier, that’s always better.”
With every successful test, the integrated NASA and Lockheed Martin team brings the X-59 closer to first flight, and closer to making aviation history through quiet supersonic technology.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The Starling swarm’s extended mission tested advanced autonomous maneuvering capabilities.NASA/Daniel Rutter As missions to low Earth orbit become more frequent, space traffic coordination remains a key element to efficiently operating in space. Different satellite operators using autonomous systems need to operate together and manage increasing workloads. NASA’s Starling spacecraft swarm recently tested a coordination with SpaceX’s Starlink constellation, demonstrating a potential solution to enhance space traffic coordination.
Led by the Small Spacecraft Technology program at NASA’s Ames Research Center in California’s Silicon Valley, Starling originally set out to demonstrate autonomous planning and execution of orbital maneuvers with the mission’s four small spacecraft. After achieving its primary objectives, the Starling mission expanded to become Starling 1.5, an experiment to demonstrate maneuvers between the Starling swarm and SpaceX’s Starlink satellites, which also maneuver autonomously.
Coordination in Low Earth Orbit
Current space traffic coordination systems screen trajectories of spacecraft and objects in space and alert operators on the ground of potential conjunctions, which occur when two objects exceed an operator’s tolerance for a close approach along their orbital paths. Spacecraft operators can request notification at a range of probabilities, often anywhere from a 1 in 10,000 likelihood of a collision to 1 in 1,000,000 or lower.
Conjunction mitigation between satellite operators requires manual coordination through calls or emails on the ground. An operator may receive a notification for a number of reasons including recently maneuvering their satellite, nearby space debris, or if another satellite adjusts its orbit.
Once an operator is aware of a potential conjunction, they must work together with other operators to reduce the probability of a collision. This can result in time-consuming calls or emails between ground operations teams with different approaches to safe operations. It also means maneuvers may require several days to plan and implement. This timeline can be challenging for missions that require quick adjustments to capture important data.
“Occasionally, we’ll do a maneuver that we find out wasn’t necessary if we could have waited before making a decision. Sometimes you can’t wait three days to reposition and observe. Being able to react within a few hours can make new satellite observations possible,” said Nathan Benz, project manager of Starling 1.5 at NASA Ames.
Improving Coordination for Autonomous Maneuvering
The first step in improving coordination was to develop a reliable way to signal maneuver responsibility between operators. “Usually, SpaceX takes the responsibility to move out of the way when another operator shares their predicted trajectory information,” said Benz.
SpaceX and NASA collaborated to design a conjunction screening service, which SpaceX then implemented. Satellite operators can submit trajectories and receive conjunction data quickly, then accept responsibility to maneuver away from a potential conjunction.
“For this experiment, NASA’s Starling accepted responsibility to move using the screening service, successfully tested our system’s performance, then autonomously planned and executed the maneuver for the NASA Starling satellite, resolving a close approach with a Starlink satellite,” said Benz.
Through NASA’s Starling 1.5 experiment, the agency helped validate SpaceX’s Starlink screening service. The Office of Space Commerce within the U.S. Department of Commerce also worked with SpaceX to understand and assess the Starlink screening service.
Quicker Response to Changes on Earth
The time it takes to plan maneuvers in today’s orbital traffic environment limits the number of satellites a human operator can manage and their ability to collect data or serve customers.
“A fully automated system that is flexible and adaptable between satellite constellations is ideal for an environment of multiple satellite operators, all of whom have differing criteria for mitigating collision risks,” said Lauri Newman, program officer for NASA’s Conjunction Assessment Risk Analysis program at the agency’s headquarters in Washington.
Reducing the time necessary to plan maneuvers could open up a new class of missions, where quick responses to changes in space or on Earth’s surface are possible. Satellites capable of making quicker movements could adjust their orbital position to capture a natural disaster from above, or respond to one swarm member’s interesting observations, moving to provide a more thorough look.
“With improved access and use of low Earth orbit and the necessity to provide a more advanced space traffic coordination system, Starling 1.5 is providing critical data. Starling 1.5 is the result of a successful partnership between NASA, the Department of Commerce, and SpaceX, maturing technology to solve such challenges,” said Roger Hunter, program manager of the Small Spacecraft Technology program. “We look forward to the sustained impact of the Starling technologies as they continue demonstrating advancements in spacecraft coordination, cooperation, and autonomy.”
NASA Ames leads the Starling projects. NASA’s Small Spacecraft Technology program within the Space Technology Mission Directorate funds and manages the Starling mission.
