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.”

Hubble Sees a Spiral and a Star
This NASA/ESA Hubble Space Telescope image features a sparkling spiral galaxy paired with a prominent star, both in the constellation Virgo. While the galaxy and the star appear to be close to one another, even overlapping, they’re actually a great distance apart. The star, marked with four long diffraction spikes, is in our own galaxy. It’s just 7,109 light-years away from Earth. The galaxy, named NGC 4900, lies about 45 million light-years from Earth.
This image combines data from two of Hubble’s instruments: the Advanced Camera for Surveys, installed in 2002 and still in operation today, and the older Wide Field and Planetary Camera 2, which was in use from 1993 to 2009. The data used here were taken more than 20 years apart for two different observing programs — a real testament to Hubble’s long scientific lifetime!
Both programs aimed to understand the demise of massive stars. In one, researchers studied the sites of past supernovae, aiming to estimate the masses of the stars that exploded and investigate how supernovae interact with their surroundings. They selected NGC 4900 for the study because it hosted a supernova named SN 1999br.
In the other program, researchers laid the groundwork for studying future supernovae by collecting images of more than 150 nearby galaxies. When researchers detect a supernova in one of these galaxies, they can refer to these images, examining the star at the location of the supernova. Identifying a supernova progenitor star in pre-explosion images gives valuable information about how, when, and why supernovae occur.

The FireSense Project

The FireSense ProjectExpanded coverage of topics from “The Editor’s Corner” in The Earth Observer
Wind is a major factor in fire. It controls how fires evolve and pose threats to the safety of communities. Traditionally data from weather balloons have been used to produce vertical soundings to define changes in atmospheric dynamics. However, their use is restricted during aircraft operations to combat active wildfires. New technologies are therefore needed to fill this critical measurement gap. The Uninhabited Aerial System (UAS) fits the bill, providing data that enables localized forecasting to help predict fire behavior.
The NASA Earth Science Division FireSense project, together with agency, academic, and private partners, completed an airborne campaign in a wildfire smoke-impacted airshed in Missoula, MT on August 27–29, 2024. During the three-day campaign, a NASA UAS team conducted eight data-collection flights– see Figure. They partnered these launches with weather balloon launches.
Using this real-time data, MITRE Corporation tested high-resolution “Score-based Data Assimilation” meteorological models and the National Oceanic and Atmospheric Administration (NOAA) High-Resolution Rapid Refresh (HRRR) operational atmospheric model against wind speed and temperature from local MesoNet weather stations. Environmental Systems Research Institute (ESRI) created comprehensive visualizations of flight paths, temperature, and wind.
The data collected during the Montana campaign were used to evaluate the impact of real-time data on model fire weather forecasts commonly used for operational decision making. The UAS sounding data were validated against weather ballon data. In addition, the campaign evaluated data validity from in-situ UAS soundings in a smoke impacted environment as well as assessed payload portability and user experience with the systems. The campaign served as a trial for interagency coordination between NOAA incident meteorologists and U.S. Forest Service (USFS) trained UAS pilots conducting data collection flights.
