Joseph Ladner’s experiences working at NASA’s Stennis Space Center near Bay St. Louis, Mississippi, motivate him to “pay it forward” so more people can be a part of something great.

“It is exciting to be at a place like NASA Stennis that continues to reinvent itself to stay relevant,” Ladner said. “You can do just about anything you can imagine with a workforce committed to its success.”

The Gulfport, Mississippi, resident is the lead budget analyst in the NASA Stennis Office of the Chief Financial Officer. His team manages budgets that fund the nation’s premier propulsion test site.

Ladner can point to three pivotal moments propelling him to a career with NASA. The first came by attending ASTRO CAMP at NASA Stennis every summer as a child. The thrilling experiences of launching paper rockets and conducting science experiments left him with the question, “How do I get to work there?”

The answer came into focus years later. Much like launching paper rockets, Ladner’s career started at ground level before reaching higher heights.

He started on the lowest end of the General Schedule pay scale as a GS-1 clerk for the Naval Oceanographic Office, located at NASA Stennis, while attending Mississippi Gulf Coast Community College.

A second pivotal moment also came during this time. The Saucier, Mississippi, native credits mentor Pamela Stenum for putting him on a career path in procurement so he could use the math and analytical skills that came natural to him.

The clerk role, expected to be only for one semester, continued through Ladner’s studies at The University of Southern Mississippi, where he earned a bachelor’s degree in Business Administration.

“I literally came in from the bottom, and someone saw potential in me,” Ladner said. “She realized I was a hard worker and that I cared about the product I was putting out.”

The third, and most profound, moment leading Ladner to a NASA career happened when the space shuttle Columbia orbiter suffered a catastrophic failure during return to Earth.

“I will never forget standing in the crowd that morning waiting for the launch of Columbia (in 2003) and hearing the commander over the loudspeakers thank everyone for the efforts to get them to this point and saying farewell to his family,” Ladner said. “No one knew it would ultimately be the crew’s last farewell. That tragic incident left me with a greater sense that there are many opportunities, but life is short. That thought and NASA’s return to flight mission left me with a desire to be part of NASA.”

Ladner started his career with the agency two years later and has worked inspired ever since. His role as lead budget analyst contributes to the Artemis campaign that will establish the foundation for long-term scientific exploration of the Moon, land the first woman, first person of color, and its first international partner astronaut on the lunar surface, and prepare for human expeditions to Mars for the benefit of all.

His job currently involves navigating challenges of increased costs and reduced budgets. From Ladner’s perspective, the challenges present opportunities for innovation and new ideas. 

“Knowing my work is part of a greater cause impacting the Artemis Generation that could make a difference to society is the best thing about working at NASA Stennis,” Ladner said. “There is some awe and wonder about working at NASA, so it is neat to say you are a part of that.”

Parked under the lights inside a hangar in Seattle, a hybrid electric research aircraft from electric motor manufacturer magniX showed off a new look symbolizing its journey toward helping NASA make sustainable aviation a reality.  

During a special unveiling ceremony hosted by magniX on Aug. 22, leaders from the company and NASA revealed the aircraft, with its new livery, to the public for the first time at King County International Airport, commonly known as Boeing Field.  

The aircraft is a De Havilland Dash 7 that was formerly used for carrying cargo. Working under NASA’s Electrified Powertrain Flight Demonstration (EPFD) project, magniX will modify it to serve as a testbed for hybrid electric aircraft propulsion research.    

The company’s goal under EPFD is to demonstrate potential fuel savings and performance boosts with a hybrid electric system for regional aircraft carrying up to 50 passengers. These efforts will help reduce environmental impacts from aviation by lowering greenhouse gas emissions. 

This livery recognizes the collaborative effort focused on proving that hybrid electric flight for commercial aircraft is feasible. 

“We are a research organization that continues to advance aviation, solve the problems of flight, and lead the community into the future,” said Robert A. Pearce, associate administrator for NASA’s Aeronautics Research Mission Directorate. “Through our EPFD project, we’re taking big steps in partnership to make sure electric aviation is part of the future of commercial flight.”

Collaborative Effort   

NASA is collaborating with industry to modify existing planes with new electrified aircraft propulsion systems. These aircraft testbeds will help demonstrate the benefits of hybrid electric propulsion systems in reducing fuel burn and emissions for future commercial aircraft, part of NASA’s broader mission to make air travel more sustainable.  

“EPFD is about showing how regional-scale aircraft, through ground and flight tests, can be made more sustainable through electric technology that is available right now,” said Ben Loxton, vice president for magniX’s work on the EPFD project.  

Thus far, magniX has focused on developing a battery-powered engine and testing it on the ground to make sure it will be safe for work in the air. The company will now begin transitioning over to a new phase of the project — transforming the Dash 7 into a hybrid electric research vehicle.  

“With the recent completion of our preliminary design review and baseline flight tests, this marks a transition to the next phase, and the most exciting phase of the project: the modification of this Dash 7 with our magniX electric powertrain,” Loxton said.  

To make this possible, magniX is working with their airframe integrator AeroTEC to help modify and prepare the aircraft for flight tests that will take place out of Moses Lake, Washington. Air Tindi, which supplied the aircraft to magniX for this project, will help with maintenance and support of the aircraft during the testing phases.  

A four engine turboprop aircraft wrapped in a red and white livery with logos and names of each partner on the project sits under the lights inside an aircraft hangar. On the ground in front of the plane is an electric powertrain with an electric motor and battery pack that will soon be swapped out with one of the aircraft’s traditional engines to form a hybrid electric system.

Creating a Hybrid Electric Aircraft   

A typical hybrid electric propulsion system combines different sources of energy, such as fuel and electricity, to power an aircraft. For magniX’s demonstration, the modified Dash 7 will feature two electric engines fed by battery packs stored in the cabin, and two gas-powered turboprops.  

The work will begin with replacing one of the aircraft’s outer turboprop engines with a new, magni650-kilowatt electric engine – the base of its hybrid electric system. After testing those modifications, magniX will swap out the remaining outer turboprop engine for an additional electric one. 

Earlier this year, magniX and NASA marked the milestone completion of successfully testing the battery-powered engine at simulated altitude. Engineers at magniX are continuing ground tests of the aircraft’s electrified systems and components at NASA’s Electric Aircraft Testbed (NEAT) facility in Sandusky, Ohio.  

By rigorously testing these new technologies under simulated flight conditions, such as high altitudes and extreme temperatures, researchers can ensure each component operates safely before taking to the skies. 

The collaboration between EPFD, NASA, GE Aerospace, and magniX works to advance hybrid electric aircraft propulsion technologies for next-generation commercial aircraft in the mid-2030 timeframe. NASA is working with these companies to conduct two flight demonstrations showcasing different approaches to hybrid electric system design. 

Researchers will use data gathered from ground and flight tests to identify and reduce certification gaps, as well as inform the development of new standards and regulations for future electrified aircraft. 

“We at NASA are excited about EPFD’s potential to make aviation more sustainable,” Pearce said. “Hybrid electric propulsion on a megawatt scale accelerates U.S. progress toward its goal of net-zero greenhouse gas emissions by 2050, benefitting all who rely on air transportation every day.”

Human research and U.S. spacecraft operations were the primary activities aboard the International Space Station on Tuesday. The crew is exploring how the human body adapts to microgravity while also preparing Boeing’s Starliner spacecraft for its departure at the end of the week.

Expedition 71 Flight Engineer Matthew Dominick kicked off his day setting up wearable biomedical hardware then working out to understand how living in space affects the human heart and breathing. He first put on a vest and headband packed with sensors measuring his heart and breathing rate, blood pressure, and other health parameters. Next, he pedaled on the Destiny laboratory module’s exercise cycle while his cardio-respiratory data was recorded to a computer. Scientists will study the results to understand how weightlessness affects a crew member’s blood pressure and breathing and learn how to keep astronauts healthy on missions to the Moon, Mars, and beyond.

Dominick joined fellow NASA astronauts Mike Barratt and Tracy C. Dyson for eye exams as personnel on the ground monitored the checks in real time. Dyson took charge as the crew medical officer operating a medical imaging device in the Harmony module viewing her crewmates’ optic nerve, retina, and cornea. Some astronauts have reported vision issues and doctors have noted changes in eye structure that they seek to understand and counter to ensure successful long-term space expeditions.

Space physics and life support research were also on the science schedule to help NASA and its international partners design next generation spacecraft and space habitats for lunar and planetary human missions. NASA Flight Engineer Jeanette Epps opened up the Combustion Integrated Rack inside Destiny and replaced and cleaned research components for a series of fire safety investigations. The experiments explore how flames spread, how materials burn, and ways to extinguish fires in microgravity to improve safety in space. Dyson swapped out test life support gear inside the Packed Bed Reactor Experiment taking place inside Destiny’s Microgravity Science Glovebox. The investigation is exploring advanced water recovery systems for crew missions in a variety of gravity scenarios.

Dominick and Barratt also reviewed operations procedures inside the SpaceX Dragon Endeavour spacecraft ahead of the Crew-8 departure later this month. The duo then invited NASA astronauts Butch Wilmore and Suni Williams inside Dragon bringing the pair up-to-speed with the spacecraft’s systems and crew configuration. Wilmore and Williams will return to Earth aboard another Dragon when Crew-9 ends its mission in February.

Wilmore and Williams, both veteran NASA astronauts, prepared Starliner for its weekend departure. The Starliner commander and pilot reconfigured the spacecraft’s seats for an uncrewed landing and packed cargo inside the vehicle this week for retrieval on Earth. They also returned standard visiting vehicle emergency hardware stowed inside Starliner back to the station for future mission operations.

Starliner is due to end its stay at the orbital outpost at 6:04 p.m. EDT on Friday and undock from Harmony’s forward port. The uncrewed spacecraft from Boeing will return to Earth and land in New Mexico about six hours later. Undocking coverage begins at 5:45 p.m. Friday on NASA+, the NASA appYouTube, and the agency’s website.

In the Roscosmos segment of the orbital outpost, station Commander Oleg Kononenko checked power generation and life support systems then set up Earth observation hardware to image the atmosphere in infrared and visible spectral ranges. Flight Engineers Nikolai Chub and Alexander Grebenkin joined each other and tested an anti-gravity suit for its ability to counter the effects of weightless on the human body and help crews adjust quicker to the return to Earth’s gravity.

El equipo que prepara el X-59 de la NASA continúa realizando pruebas en preparación para que el avión supersónico y silencioso realice su primer vuelo. Esto incluye un trío de importantes pruebas estructurales e inspecciones críticas en el camino hacia el vuelo.

El X-59 es un avión experimental que volará más rápido que la velocidad del sonido sin un fuerte estampido sónico. Será el primero de su clase en volar, con el objetivo de recopilar datos de sonido para la misión Quesst de la NASA, que podría abrir la puerta a vuelos supersónicos comerciales sobre tierra en el futuro.

Debido a su diseño único, el equipo de ingenieria del X-59 debe hacer todo lo posible para predecir cada aspecto del avión antes de que despegue, incluyendo cómo se comportarán juntos su fuselaje, las alas y las superficies de control en vuelo. Eso significa que las pruebas en la tierra darán al equipo los datos necesarios para validar los modelos que han desarrollado.

Las pruebas no sólo nos dicen que tan estructuralmente sólido es el avión, sino también qué tipo de fuerzas puede soportar una vez que esté en el aire.

Las pruebas estructurales del X-59 proporcionan información valiosa para el equipo. Entre 2022 y 2024, los ingenieros recopilaron datos sobre las fuerzas que el avión experimentará en vuelo y los efectos potenciales de las vibraciones en el avión.

“Haces estas pruebas, obtienes los datos, y las cosas se comparan bien en algunas áreas y en otras quieres mejorarlas,” Silva dijo. “Así que lo averiguas todo y luego trabajas para mejorarlo.”

A principios de este año, el X-59 se sometió a pruebas de acoplamiento estructural que vieron sus superficies de control, incluyendo sus alerones, aletas y timón, movidos por computadora. Fue la última de tres pruebas estructurales vitales. En 2023, los ingenieros aplicaron “agitadores” a partes del avión para evaluar su reacción a las vibraciones, y a principios de 2022 realizaron un examen de prueba para asegurar que el avión absorberá las fuerzas que experimentará durante el vuelo. Este año se instaló el asiento eyectable del X-59 y pasó su inspección. El asiento eyectable es una medida de seguridad adicional que es crítica para la seguridad del piloto durante todo aspecto del vuelo.

Con las pruebas estructurales y la instalación del asiento eyectable finalizadas, el avion avanzará hacia un nuevo hito: encenderá sus motores para una serie de pruebas en tierra.

El X-59 también tiene por delante la prueba del sistema de aviónica y cableado extensivo para detectar posibles interferencias electromagnéticas, imitando las condiciones de vuelo en un entorno de pruebas en tierra y finalmente, completar las pruebas de rodaje para validar la movilidad en tierra antes de su primer vuelo.

“Los primeros vuelos siempre son muy intensos,” dijo Natalie Spivey, ingeniera aeroespacial del Centro de Investigación de Vuelo Armstrong de la NASA en Edwards, California. “Hay mucha anticipación, pero estamos listos para llegar allí y ver cómo responde el avion en el aire. Será muy emocionante.”
