How NASA’s “Autonomy Choreography” Will Impact Advanced Technologies

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.”

NASA Uses Advanced Radar to Track Groundwater in California

NASA Uses Advanced Radar to Track Groundwater in California

Where California’s towering Sierra Nevada surrender to the sprawling San Joaquin Valley, a high-stakes detective story is unfolding. The culprit isn’t a person but a process: the mysterious journey of snowmelt as it travels underground to replenish depleted groundwater reserves.  

The investigator is a NASA jet equipped with radar technology so sensitive it can detect ground movements thinner than a nickel. The work could unlock solutions to one of the American West’s most pressing water challenges — preventing groundwater supplies from running dry.    

“NASA’s technology has the potential to give us unprecedented precision in measuring where snowmelt is recharging groundwater,” said Erin Urquhart, program manager for NASA’s Earth Action Water Resources program at NASA Headquarters in Washington. “This information is vital for farmers, water managers, and policymakers trying to make the best possible decisions to protect water supplies for agriculture and communities.”  

Tracking Water Beneath the Surface  

In late February, a NASA aircraft equipped with Uninhabited Aerial Vehicle Synthetic Aperture Radar (UAVSAR) conducted the first of six flights planned for this year, passing over a roughly 25-mile stretch of the Tulare Basin in the San Joaquin Valley, where foothills meet farmland. It’s a zone experts think holds a key to maintaining water supplies for one of America’s most productive agricultural regions.   

Much of the San Joaquin Valley’s groundwater comes from the melting of Sierra Nevada snow. “For generations, we’ve been managing water in California without truly knowing where that meltwater seeps underground and replenishes groundwater,” said Stanford University geophysicist and professor Rosemary Knight, who is leading the research.    

The process is largely invisible — moisture filtering through rock and sediment, and vanishing beneath orchards and fields. But as the liquid moves downhill, it follows a pattern. Water flows into rivers and streams, some of it eventually seeping underground at the valley’s edge or as the waterways spread into the valley. As the water moves through the ground, it can create slight pressure that in turn pushes the surface upward. The movement is imperceptible to the human eye, but NASA’s advanced radar technology can detect it.  

“Synthetic aperture radar doesn’t directly see water,” explained Yunling Lou, who leads the UAVSAR program at NASA’s Jet Propulsion Laboratory in Southern California. “We’re measuring changes in surface elevation — smaller than a centimeter — that tell us where the water is.”   

These surface bulges create what Knight calls an “InSAR recharge signature.” By tracking how these surface bulges migrate from the mountains into the valley, the team hopes to pinpoint where groundwater replenishment occurs and, ultimately, quantify the amount of water naturally recharging the system.  

Previous research using satellite-based InSAR (Interferometric Synthetic Aperture Radar) has shown that land in the San Joaquin Valley uplifts and subsides with the seasons, as the groundwater is replenished by Sierra snowmelt. But the satellite radar couldn’t uniquely identify the recharge paths. Knight’s team combined the satellite data with images of underground sediments, acquired using an airborne electromagnetic system, and was able to map the major hidden subsurface water pathways responsible for aquifer recharge.   

NASA’s airborne UAVSAR system will provide even more detailed data, potentially allowing researchers to have a clearer view of where and how fast water is soaking back into the ground and recharging the depleted aquifers.  

Supporting Farmers and Communities   

California’s Central Valley produces over a third of America’s vegetables and two-thirds of its fruits and nuts. The southern portion of this agricultural powerhouse is the San Joaquin Valley, where most farming operations rely heavily on groundwater, especially during drought years.   

Water managers have occasionally been forced to impose restrictions on groundwater pumping as aquifer levels drop. Some farmers now drill increasingly deeper wells, driving up costs and depleting reserves.  
  
“Knowing where recharge is happening is vital for smart water management,” said Aaron Fukuda, general manager of the Tulare Irrigation District, a water management agency in Tulare County that oversees irrigation and groundwater recharge projects.   

“In dry years, when we get limited opportunities, we can direct flood releases to areas that recharge efficiently, avoiding places where water would just evaporate or take too long to soak in,” Fukuda said. “In wetter years, like 2023, it’s even more crucial — we need to move water into the ground as quickly as possible to prevent flooding and maximize the amount absorbed.”  

NASA’s Expanding Role in Water Monitoring  

NASA’s ongoing work to monitor and manage Earth’s water combines a range of cutting-edge technologies that complement one another, each contributing unique insights into the challenges of groundwater management.  

The upcoming NISAR (NASA-ISRO Synthetic Aperture Radar) mission, a joint project between NASA and the Indian Space Research Organisation (ISRO) set to launch in coming months, will provide global-scale radar data to track land and ice surface changes — including signatures of groundwater movement — every 12 days.    

In parallel, the GRACE satellites — operated by the German Aerospace Center, German Research Centre for Geosciences, and NASA — have transformed global groundwater monitoring by detecting tiny variations in Earth’s gravity, offering a broad view of monthly water storage changes across large regions.   

The Gravity Recovery and Climate Experiment and Follow-On (GRACE and GRACE-FO) missions have helped expose major declines in aquifers, including in California’s Central Valley. But their coarser resolution calls for complementary tools that can, for example, pinpoint recharge hotspots with greater precision.  

Together, these technologies form a powerful suite of tools that bridge the gap between regional-scale monitoring and localized water management. NASA’s Western Water Applications Office (WWAO) also plays a key role in ensuring that this wealth of data is accessible to water managers and others, offering platforms like the Visualization of In-situ and Remotely-Sensed Groundwater Observation (VIRGO) dashboard to facilitate informed decision-making.  

“Airborne campaigns like this one in the San Joaquin test how our technology can deliver tangible benefits to American communities,” said Stephanie Granger, WWAO’s director at NASA’s Jet Propulsion Laboratory. “We partner with local water managers to evaluate tools that have the potential to strengthen water supplies across the Western United States.”

NASA Langley Dedicates Artemis Moon Tree

A tree that sprouted from a seed that journeyed around the Moon and back is growing at NASA’s Langley Research Center in Hampton, Virginia.

NASA’s Acting Associate Administrator for NASA’s Exploration Systems Development Mission Directorate Lori Glaze and NASA Langley Acting Center Director Trina Dyal spoke at a dedication ceremony for the Artemis Moon Tree, a loblolly pine, at the center March 12.

“I wanted to quote an old Greek proverb that more or less says something like, ‘Society grows when its elders plant trees whose shade they know they shall never sit in,’ ” said Glaze. “I love that. We always talk about how we stand on the shoulders of giants. Those giants planted seeds, and we are still benefiting from the tremendous roots of those trees,”

The young tree, only about two feet tall right now, is growing in an area between NASA Langley’s Integrated Engineering Services Building and its Measurement Systems Laboratory. The pine is surrounded by a wire plant protector. A yellow label identifies the species and the location of the U.S. Department of Agriculture Forest Services nursery where the seedling was grown — Charles E. Bessey Nursery in Halsey, Nebraska. A small plaque marks its status as a Moon Tree.

“This, we plant here for all future generations to be inspired and to continue on the amazing legacy of what we’re doing,” said Glaze. “Our return to the lunar surface and our journey to Mars through the Artemis campaign is really going to lay the foundation for that future of exploration that right now we’re only dreaming about. With your help, through Langley and the rest of our NASA colleagues and partners, we’re going to achieve those visions.”

The loblolly seed was one of many that flew on the Artemis I mission Nov. 16 to Dec. 11, 2022 — journeying 270,000 miles from Earth aboard the Orion spacecraft. NASA’s Office of STEM Engagement partnered with the Forest Services to fly the seeds aboard Artemis I as part of a national STEM Engagement and conservation education initiative. 

In addition to loblolly pines, tree species on the flight included sycamores, sweetgums, Douglas firs, and giant sequoias. The Forest Services germinated the seeds.

Locally, NASA Langley’s loblolly pine is one of three Artemis Moon Trees. The Virginia Living Museum in Newport News and the Virginia Zoo in Norfolk were also selected as Moon Tree stewards, and also received loblolly pines.

The Artemis Moon Trees take inspiration from their Apollo precursors. In 1971, NASA astronaut Stuart Roosa, the command module pilot for the Apollo 14 mission and a former U.S. Department of Agriculture Forest Services smoke jumper, carried tree seeds into lunar orbit. The Apollo 14 Moon Trees were disseminated to national monuments and dignitaries around the world, with a large number distributed as part of the nation’s bicentennial event.  

One of those Moon Trees, a sycamore, was planted at Albert W. Patrick III Elementary School in the Fox Hill area of Hampton in 1976. Sixth grader Marjorie White wrote a poem called “A Tree Lives” that won a contest to earn the honor.

Fallout from the Unauthorized Gemini III Space Sandwich

Fallout from the Unauthorized Gemini III Space Sandwich

“I hid a sandwich in my spacesuit,” Astronaut John W. Young confessed in the April 2, 1965, issue of Life Magazine. The conversation about and the consumption of the sandwich, which lasted only about 30 seconds during the Gemini III flight, became a serious matter that drew the ire of Congress and NASA’s administrator after the crew returned home. Congress was particularly upset and brought the matter to leadership’s attention at hearings about NASA’s 1966 budget. Representative George E. Shipley was especially disgusted, knowing how much money and time NASA had spent to prepare the Gemini III spacecraft for launch. The fact that a crewmember brought something into the crew cabin, which Shipley likened to a “surgeon’s operating room,” put the techniques used to prevent a spaceflight mission from failing at risk; crumbs could have made their way behind instrument panels interfering with the operation of flight equipment and the loss of the mission and its crew. Shipley called Young’s antics “foolish” and asked NASA leaders to share their thoughts.

A Beef with Corned Beef

George Mueller, associate administrator for Manned Space Flight, stated unequivocally that the agency did not “approve [of] unauthorized objects such as sandwiches going on board the spacecraft.” And he promised Shipley that NASA has “taken steps, obviously, to prevent recurrence of corned beef sandwiches in future flights. There was no detriment to the experimental program that was carried on, nor was there any detriment to the actual carrying out of the mission because of the ingestion of the sandwich.” Manned Spacecraft Center Director Robert R. Gilruth was more forgiving of Young’s decision. These sort of antics, he told the committee, helped the crews to “break up the strain” of spaceflight, and he hesitated “to be too strict in the future by laying down a lot of rules for men who have this responsibility and who, in all the flights so far, have done such good jobs.” Webb disagreed and said, “this is the United States of America’s space program and, as a matter of policy, we are not going to permit individuals to superimpose their judgment as to what is going to be taken on these flights. I think it is fine for Dr. Gilruth to take a very strong position with respect to the individuality of these men, but from those of us who have to look at the totality of the matter, this was not an adequate performance by an astronaut.”

The loss of a Gemini mission, especially one so early in the program, would have been particularly challenging for an agency attempting to land humans on the Moon where each mission built on the previous flight. The United States was in a race with the Soviet Union, and for Congress at least, the purpose of Gemini and the cost of the space program was far too serious for these sorts of fun and games. For NASA Administrator James Webb, it was a sign that Gilruth was too lax when it came to managing his astronauts. Gemini III was just one example of the lack of control he noticed, and he pressed Gilruth for a report on the sandwich incident to determine if Young should be disciplined or at the very least reprimanded.

The In-Flight Meal

Young hatched the idea during training, when his commander, Virgil I. “Gus” Grissom grew “bored” with the food they practiced with for the mission. Grissom regularly complained about the dehydrated “delicacies” food scientists concocted. Bringing a sandwich onboard, an item that was freshly made and did not have to be rehydrated, “seemed like a fun idea at the time” to Young.

One of the goals of their flight was to evaluate NASA’s flight food packaging and whether the containers leaked when foods were reconstituted, as well as the procedures for disposing of the meal and its packaging after eating. Foods included rehydratable items such as chicken bites, applesauce, or drinks, and compressed foods such as brownie bites. The Gemini food system was not haute cuisine, however, and crews complained about its taste. Young described the chicken bites as “barely edible” in his post-flight debriefing. Don L. Lind, a scientist-astronaut selected in 1967, described the early Gemini food as “strange.” Their class took some to jungle survival training in Panama, and while no one wanted to eat it on the first two days, by the third day they were so hungry that they were willing to give it a try. Another problem was that all rehydrated meals for Gemini were mixed with cold water, which made them less appetizing than a hot meal.

A freshly made corned beef sandwich made at a local restaurant sounded like a better option, so Young had fellow astronaut and backup command pilot Walter M. “Wally” Schirra pick one up. Schirra purchased the sandwich for Young, and as he headed out to the launchpad, Young put it in the pocket of his pressure suit.

Nearly two hours into the flight, as Young started his food and waste evaluation, he pulled out the sandwich from his suit and offered it to his commander. As captured on the air-to-ground recordings, Grissom asked what it was and where it came from. “I brought it with me,” Young responded, “Let’s see how it tastes.” He didn’t expect the sandwich to be so pungent, “Smells, doesn’t it?” Grissom took a bite but found the rye crumbled so he placed the sandwich in his suit pocket to prevent the crumbs from floating about the cabin.

Where did that come from?

Gus Grissom

Gemini III Commander

Two days later, nearly a thousand members of the media from the United States and around the world gathered to hear from the crew and NASA management at the postflight press conference at the Carriage House Motel in Cocoa Beach, Florida. Space reporter Bill Hines asked Young about the sandwich, erroneously referring to it as a “baloney sandwich,” and what happened when Gus was offered a taste. “And,” he asked, “what became of the sandwich?” Young seemed surprised, “How did you find out about that?” and then laughed adding Grissom “ate the sandwich.”

Carry-on Restrictions for Spaceflights

Ironically the Gemini Program offered astronauts more control over their flights than during Project Mercury, including the ability to maneuver their spacecraft and to be more independent from Mission Control; but the uproar over this event led NASA to draft rules about what astronauts could and could not take onboard a spacecraft. Starting with Gemini IV, flight crews had to present a list of items they planned to take on their missions. Prohibited items naturally included sandwiches as well as bulky or heavy items or metal that could negatively impact the operation of spacecraft equipment. (NASA still allowed astronauts to take personal items such as wedding bands or coins for families and friends in their personal preference kit.)

Young never received a formal reprimand for the incident but was made aware of Congress’s frustration. Others in the corps were advised to avoid similar stunts and to focus on the mission. The decision to bring a sandwich onboard did not have a negative impact on Young’s career. He was the first astronaut to fly to space six times —two Gemini missions; two Apollo missions, including the dress rehearsal for the first lunar landing; and two space shuttle missions including STS-1, known as the bravest test flight in history. He also served as chief of the Astronaut Office for 13 years.
