      As humanity prepares to return to the lunar surface, Aaisha Ali is behind the scenes ensuring mission readiness for astronauts set to orbit the Moon during Artemis II. 
      Ali is the Artemis ground control flight lead at NASA’s Johnson Space Center in Houston. She makes sure her team has the resources needed for the next giant leap to the Moon and beyond.

      Artemis Ground Control Flight Lead
      Ali received a bachelor’s degree in biology from Texas A&M University at Galveston before beginning a career as a marine biologist. Her curiosity about science and communication eventually led her from studying marine life to sharing NASA’s mission with the public. With a robust skill set that includes public relations, media relations, and strategic communications, she went on to work at Space Center Houston and later at Johnson on the protocol and digital imagery teams.
      Today, Ali leads the ground control team supporting Artemis II, ensuring that systems, simulations, and procedures are ready for the mission. Her role includes developing flight rules, finalizing operations plans and leading training sessions – known as “network sims” – that prepare her team to respond quickly and effectively. 
      “Because I’ve had a multifaceted career path, it has given me a different outlook,” she said. “Diversity of mindsets helps us approach problems. Sometimes a different angle is exactly what we need.”

Her perspective was also shaped by visits to her grandmother in the Caribbean as a child. “She lived in the tropical forest in a small village in Trinidad,” Ali said. “I was fortunate enough to spend summers on the island and experience a different way of life, which has helped me grow into the person I am today.”  
      Communication, she explained, is just as critical as technical expertise. “When we report to the flight director, we are the experts in our system. But we have to be clear and concise. You don’t get a lot of time on the flight loop to explain.” 
      That clarity, humility, and sense of teamwork are values Ali says have shaped her journey. 
      Aaisha Ali participates in a public affairs event at Ellington Field Joint Reserve Base in Houston in 2005. We don’t do it by ourselves. Everyone — from our engineers to custodial staff to cafeteria workers — plays a role in getting us to the Moon. NASA is for the world. And it takes all of us.

      Looking ahead, Ali is especially passionate about inspiring the Artemis Generation — those who will one day explore the Moon and Mars. She often shares advice with her nieces and nephews, including one determined nephew who has dreamed of becoming an astronaut since age 7. 
      “Do what you love, and NASA will find a place for you,” she said. “NASA is a big place. If you love the law, we have lawyers. If you love art, science, or technology, there’s a place for you. Passion is what we’re looking for.” 
      Aaisha Ali at Walt Disney World in Orlando, Florida. In her free time, Ali enjoys photography and connecting with nature by camping and visiting national parks. She also loves planning trips to Walt Disney World, meeting new people, experiencing different cultures, and learning new things. 
      Even as her days are packed with simulations and mission prep, Ali knows landing astronauts on the lunar surface for Artemis III is not far behind. 
      “There’s a lot of uphill left to climb,” she said. “But we’re ready.”

      A NASA-sponsored team is creating a new approach to measure magnetic fields by developing a new system that can both take scientific measurements and provide spacecraft attitude control functions. This new system is small, lightweight, and can be accommodated onboard the spacecraft, eliminating the need for the boom structure that is typically required to measure Earth’s magnetic field, thus allowing smaller, lower-cost spacecraft to take these measurements. In fact, this new system could not only enable small spacecraft to measure the magnetic field, it could replace the standard attitude control systems in future spacecraft that orbit Earth, allowing them to provide the important global measurements that enable us to understand how Earth’s magnetic field protects us from dangerous solar particles.

      Solar storms drive space weather that threatens our many assets in space and can also disrupt Earth’s upper atmosphere impacting our communications and power grids. Thankfully, the Earth’s magnetic field protects us and funnels much of that energy into the north and south poles creating aurorae. The aurorae are a beautiful display of the electromagnetic energy and currents that flow throughout the Earth’s space environment. They often have small-scale magnetic features that affect the total energy flowing through the system. Observing these small features requires multiple simultaneous observations over a broad range of spatial and temporal scales, which can be accomplished by constellations of small spacecraft.
      To enable such constellations, NASA is developing an innovative hybrid magnetometer that makes both direct current (DC) and alternating current (AC) magnetic measurements and is embedded in the spacecraft’s attitude determination and control system (ADCS)—the system that enables the satellite to know and control where it is pointing. High-performance, low SWAP+C (low-size, weight and power + cost) instruments are required, as is the ability to manufacture and test large numbers of these instruments within a typical flight build schedule. Future commercial or scientific satellites could use these small, lightweight embedded hybrid magnetometers to take the types of measurements that will expand our understanding of space weather and how Earth’s magnetic field responds to solar storms
      It is typically not possible to take research-quality DC and AC magnetic measurements using sensors within an ADCS since the ADCS is inside the spacecraft and near contaminating sources of magnetic noise such as magnetic torque rods—the electromagnets that generate a magnetic field and push against the Earth’s magnetic field to control the orientation of a spacecraft. Previous missions that have flown both DC and AC magnetometers placed them on long booms pointing in opposite directions from the satellite to keep the sensors as far from the spacecraft and each other as possible. In addition, the typical magnetometer used by an ADCS to measure the orientation of the spacecraft with respect to the geomagnetic field does not sample fast enough to measure the high-frequency signals needed to make magnetic field observations.
      A NASA-sponsored team at the University of Michigan is developing a new hybrid magnetometer and attitude determination and control system (HyMag-ADCS) that is a low-SWAP single package that can be integrated into a spacecraft without booms. HyMag-ADCS consists of a three-axis search coil AC magnetometer and a three-axis Quad-Mag DC magnetometer. The Quad-Mag DC magnetometer uses machine learning to enable boomless DC magnetometery, and the hybrid search-coil AC magnetometer includes attitude determination torque rods to enable the single 1U volume (103 cm) system to perform ADCS functions as well as collect science measurements.
      The magnetic torque rod and search coil sensor (left) and the Quad-Mag magnetometer prototype (right). Credit: Mark Moldwin The HyMag-ADCS team is incorporating the following technologies into the system to ensure success.
      Quad-Mag Hardware: The Quad-Mag DC magnetometer consists of four magneto-inductive magnetometers and a space-qualified micro-controller mounted on a single CubeSat form factor (10 x 10 cm) printed circuit board. These two types of devices are commercially available. Combining multiple sensors on a single board increases the instrument’s sensitivity by a factor of two compared to using a single sensor. In addition, the distributed sensors enable noise identification on small satellites, providing the science-grade magnetometer sensing that is key for both magnetic field measurements and attitude determination. The same type of magnetometer is part of the NASA Artemis Lunar Gateway Heliophysics Environmental and Radiation Measurement Experiment Suite (HERMES) Noisy Environment Magnetometer in a Small Integrated System (NEMISIS) magnetometer scheduled for launch in early 2027.
      Dual-use Electromagnetic Rods: The HyMag-ADCS team is using search coil electronics and torque rod electronics that were developed for other efforts in a new way. Use of these two electronics systems enables the electromagnetic rods in the HyMag-ADCS system to be used in two different ways—as torque rods for attitude determination and as search coils to make scientific measurements. The search coil electronics were designed for ground-based measurements to observe ultra-low frequency signals up to a few kHz that are generated by magnetic beacons for indoor localization. The torque rod electronics were designed for use on CubeSats and have flown on several University of Michigan CubeSats (e.g., CubeSat-investigating Atmospheric Density Response to Extreme driving [CADRE]). The HyMag-ADCS concept is to use the torque rod electronics as needed for attitude control and use the search coil electronics the rest of the time to make scientific AC magnetic field measurements.
      Machine Learning Algorithms for Spacecraft Noise Identification: Applying machine learning to these distributed sensors will autonomously remove noise generated by the spacecraft. The team is developing a powerful Unsupervised Blind Source Separation (UBSS) algorithm and a new method called Wavelet Adaptive Interference Cancellation for Underdetermined Platforms (WAIC-UP) to perform this task, and this method has already been demonstrated in simulation and the lab.
      The HyMag-ADCS system is early in its development stage, and a complete engineering design unit is under development. The project is being completed primarily with undergraduate and graduate students, providing hands-on experiential training for upcoming scientists and engineers.

      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.

      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.
