Having just finished a pre-flight mission briefing with his team, the only thing on his mind is heading to the aircraft hangar and getting a plane in the air.
      As he eases a small white-and-blue propeller aircraft down the hangar’s ramp and onto the runway, he hears five essential words crackle through his headset: “NASA 606, cleared for takeoff.”
      This is a typical morning for Johnson, a research pilot and aviation safety officer at NASA’s Glenn Research Center in Cleveland. Johnson flies NASA planes to support important scientific research and testing, working with researchers to plan and carry out flights that will get them the data they need while ensuring safety.
      Johnson hasn’t always flown in NASA planes. He comes to the agency from the U.S. Air Force, where he flew missions all over the world in C-17 cargo aircraft, piloted unmanned reconnaissance operations out of California, and trained young aviators in Oklahoma on the fundamentals of flying combat missions.

      Jeremy Johnson stands beside a C-17 aircraft before a night training flight in Altus, Oklahoma, in 2020. Before supporting vital flight research at NASA through a SkillBridge fellowship, which gives transitioning service members the opportunity to gain civilian work experience, Johnson served in the U.S. Air Force and flew C-17 airlift missions all over the world.Credit: Courtesy of Jeremy Johnson He’s at Glenn for a four-month Department of Defense SkillBridge fellowship. The program gives transitioning service members an opportunity to gain civilian work experience through training, apprenticeships, or internships during their last 180 days of service before separating from the military.
      “I think SkillBridge has been an amazing tool to help me transition into what it’s like working somewhere that isn’t the military,” Johnson said. “In the Air Force, flying the mission was the mission. At NASA Glenn, the science—the research—is the mission.”
      By flying aircraft outfitted with research hardware or carrying test equipment, Johnson has contributed to two vital projects at NASA so far. One is focused on testing how well laser systems can transmit signals for communication and navigation. The other, part of NASA’s research under Air Mobility Pathfinders, explores how 5G telecommunications infrastructure can help electric air taxis of the future be safely incorporated into the national airspace. This work, and the data that scientists can collect through flights, supports NASA’s research to advance technology and innovate for the benefit of all.

You remember, this is a small little piece of something that is maybe going to change the frontier of science, the frontier of discovery.”
      Johnson has always had a passion for aviation. In college, he worked as a valet to pay for flying lessons. To hone his skills before Air Force training, one summer he flew across the country in a Cessna with his aunt, a commercial pilot. They flew down the Hudson River as they watched the skyscrapers of New York City whizz by and later to Kitty Hawk, North Carolina, where the Wright brothers made their historic first flight. Johnson even flew skydivers part-time while he was stationed in California.

      Despite his successes, Johnson’s journey to becoming a pilot wasn’t always smooth. He recalls that as he was about to land after his first solo flight, violent crosswinds blew his plane off the runway and sent him bouncing into the grass. Though he eventually got back behind the stick for another flight, he said that in that moment he wondered whether he had the strength and skills to overcome his self-doubt.
      “I don’t know anyone who flies for a living that had a completely easy path into it,” Johnson said. “To people who are thinking about getting into flying, just forge forward with it. Make people close doors on you, don’t close them on yourself, when it comes to flying or whatever you see yourself doing in the future. I just kept knocking on the door until there was a crack in it.”

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      This artist’s concept shows astronauts working on the Moon alongside different technology systems. The Data & Reasoning Fabric technology could help these systems operate in harmony, supporting the astronauts and ground control on Earth.Credit: NASA Imagine your car is in conversation with other traffic and road signals as you travel. Those conversations help your car anticipate actions you can’t see: the sudden slowing of a truck as it begins to turn ahead of you, or an obscured traffic signal turning red. Meanwhile, this system has plotted a course that will drive you toward a station to recharge or refuel, while a conversation with a weather service prepares your windshield wipers and brakes for the rain ahead.
      This trip requires a lot of communication among systems from companies, government agencies, and organizations. How might these different entities – each with their own proprietary technology – share data safely in real time to make your trip safe, efficient, and enjoyable?
      Technologists at NASA’s Ames Research Center in California’s Silicon Valley created a framework called Data & Reasoning Fabric (DRF), a set of software infrastructure, tools, protocols, governance, and policies that allow safe, secure data sharing and logical prediction-making across different operators and machines. Originally developed with a focus on providing autonomous aviation drones with decision-making capabilities, DRF is now being explored for other applications.
      This means that one day, DRF-informed technology could allow your car to receive traffic data safely and securely from nearby stoplights and share data with other vehicles on the road. In this scenario, DRF is the choreographer of a complex dance of moving objects, ensuring each moves seamlessly in relation to one another towards a shared goal. The system is designed to create an integrated environment, combining data from systems that would otherwise be unable to interact with each other.
      “DRF is built to be used behind the scenes,” said David Alfano, chief of the Intelligent Systems Division at Ames. “Companies are developing autonomous technology, but their systems aren’t designed to work with technology from competitors. The DRF technology bridges that gap, organizing these systems to work together in harmony.”
      Traffic enhancements are just one use case for this innovative system. The technology could enhance how we use autonomy to support human needs on Earth, in the air, and even on the Moon.
      Supporting Complex Logistics
      To illustrate the technology’s impact, the DRF team worked with the city of Phoenix on an aviation solution to improve transportation of critical medical supplies from urban areas out to rural communities with limited access to these resources. An autonomous system identified where supplies were needed and directed a drone to pick up and transport supplies quickly and safely.
      “All the pieces need to come together, which takes a lot of effort. The DRF technology provides a framework where suppliers, medical centers, and drone operators can work together efficiently,” said Moustafa Abdelbaky, senior computer scientist at Ames. “The goal isn’t to remove human involvement, but help humans achieve more.”
      The DRF technology is part of a larger effort at Ames to develop concepts that enable autonomous operations while integrating them into the public and commercial sector to create safer, efficient environments.
      “At NASA, we’re always learning something. There’s a silver lining when one project ends, you can identify a new lesson learned, a new application, or a new economic opportunity to continue and scale that work,” said Supreet Kaur, lead systems engineer at Ames. “And because we leverage all of the knowledge we’ve gained through these experiments, we are able to make future research more robust.”
      Choreographed Autonomy
      Industries like modern mining involve a variety of autonomous and advanced vehicles and machinery, but these systems face the challenge of communicating sufficiently to operate in the same area. The DRF technology’s “choreography” might help them work together, improving efficiency. Researchers met with a commercial mining company to learn what issues they struggle with when using autonomous equipment to identify where DRF might provide future solutions.
      “If an autonomous drill is developed by one company, but the haul trucks are developed by another, those two machines are dancing to two different sets of music. Right now, they need to be kept apart manually for safety,” said Johnathan Stock, chief scientist for innovation at the Ames Intelligent Systems Division. “The DRF technology can harmonize their autonomous work so these mining companies can use autonomy across the board to create a safer, more effective enterprise.”
      Further testing of DRF on equipment like those used in mines could be done at the NASA Ames Roverscape, a surface that includes obstacles such as slopes and rocks, where DRF’s choreography could be put to the test.
      Stock also envisions DRF improving operations on the Moon. Autonomous vehicles could transport materials, drill, and excavate, while launch vehicles come and go. These operations will likely include systems from different companies or industries and could be choreographed by DRF.
      As autonomous systems and technologies increase across markets, on Earth, in orbit, and on the Moon, DRF researchers are ready to step on the dance floor to make sure everything runs smoothly.
      “When everyone’s dancing to the same tune, things run seamlessly, and more is possible.”
