A NASA-funded air pollution monitoring network has provided one of the most detailed long-term views yet of the role of black carbon, or soot produced by fires, diesel vehicles, and other combustion sources, in Ethiopia’s capital, Addis Ababa. The detailed measurements show how pollution changes by time of day and season, including increases associated with rush-hour traffic and holiday celebrations. The findings are relevant to cities around the world, including in the United States.
In a new paper published in ES&T: Air, scientists analyzed data collected throughout Addis Ababa between 2022 and 2025 from 10 air-quality monitoring sites deployed by NASA’s Multi-Angle Imager for Aerosols (MAIA) project.
The research comes as Ethiopia is taking steps aimed at improving air quality. In 2024, the country became the first in the world to ban the import of internal combustion engine vehicles, while cities have been adding bike lanes and electric vehicle infrastructure. The MAIA project’s measurements provide researchers with a baseline for understanding how air quality changes over time as Addis Ababa continues to grow and evolve.
The study focuses on particulate matter that is 2.5 micrometers or less in diameter, also known as PM2.5. The 2025 State of Global Air Report, cited in the paper, estimates that exposure to PM2.5 is associated with approximately 4.9 million deaths globally each year. Among the many kinds of PM2.5, black carbon has been has been studied for its potential effects on human health.
The paper found that Addis Ababa’s three-year average PM2.5 concentration was 30 micrograms per cubic meter, which is more than three times the level of the U.S. Environmental Protection Agency’s health-based annual PM2.5 standard. The new paper cites data from MAIA’s ground sensors indicating that average black carbon levels in Addis Ababa were approximately four to nine times higher than those measured in the three U.S. metropolitan areas the mission is monitoring.
This roof-mounted air sensor in Addis Ababa, the capital of Ethiopia, is one of 10 used by NASA’s MAIA mission to study the city’s air quality. MAIA’s air sensors provide a detailed look at PM2.5, one of the world’s deadliest forms of air pollution.

“To our knowledge, this is the first long-term, multisite study of continuous PM2.5 and black carbon measurements in Ethiopia,” said Sina Hasheminassab, a coauthor of the paper and MAIA’s deputy principal investigator at NASA’s Jet Propulsion Laboratory in Southern California. “Many rapidly growing cities have limited long-term monitoring, so these measurements provide an important baseline for understanding how pollution changes across space and time.”
The composition and sources of PM2.5 can differ substantially between cities, depending on their local geography, traffic, industries, and more. Desert cities, for example, may have more dust, while those near coal-fired power plants may have higher concentrations of sulfate. Long-term surface measurements remain limited in many parts of the world.
NASA is supporting MAIA’s air pollution research in a dozen metropolitan areas around the globe, including three in the U.S.: Los Angeles, Atlanta, and Boston. The mission consists of a ground-based network of sensors already in operation as well as a space observatory, which uses a JPL-built camera that will be launched by the Italian Space Agency (ASI) on an ASI satellite no earlier than late 2027.
The camera is designed to identify different types of PM2.5 aerosols based on how they reflect light, making it possible to map particle concentrations over each city that the mission studies. Mounted on a gimbal, the camera captures data from multiple angles using JPL-pioneered technologies that make particles stand out more prominently against the surface background to provide valuable information about their shape and size.
The MAIA mission is the first NASA project to include public health researchers among a space mission’s team. These researchers will use MAIA’s PM2.5 concentration maps alongside health data to study potential relationships between different particle types and health outcomes. By developing a better understanding of particulate matter pollution, researchers can potentially advance how air quality is studied and managed.
“This paper shows how valuable the air sensor data is on its own, but combining the sensor network and satellite observations will be a game-changer,” said, Kyan Shlipak, the paper’s lead author, who worked on the research while interning at JPL.

The greater Addis Ababa urban area is home to nearly 6 million people, and according to United Nations projections, that figure is expected to surpass 10 million by 2050.

“It’s a cosmopolitan city with many international communities,” said Araya Asfaw of Addis Ababa University, a coauthor of the paper and the MAIA project’s lead Ethiopian collaborator. “Think of it as Africa’s version of Brussels, where the European Union is based.”
“Even at night, when traffic dies down, you see high emissions from the burning of charcoal and other fuels,” Asfaw said.
The MAIA sensor network detected increases in black carbon during two major holidays in Addis Ababa that involve bonfires and was able to distinguish between particles originating from the fires and those from fossil fuel combustion. The findings demonstrate how detailed measurements can help researchers identify different sources of particulate matter and better understand how air quality varies across a city and over time.

The NASA Science Mission Directorate (SMD) Community of Practice for Education (SCoPE) – part of the NASA Science Activation (SciAct) Program portfolio – enables Earth and Space Science and Engineering Subject Matter Experts (SMEs) – especially NASA-funded SMEs – to efficiently and effectively share their science with support from SciAct education experts.
In Summer 2026, NASA SCoPE partnered with Arizona State University’s Facility for Open Research in a Compressed Environment (FORCE) Summer School to help seven undergraduate student interns build the science communication skills needed to share their research with a variety of audiences. FORCE is a world-class laboratory that uses high-pressure experimental equipment to recreate the extreme conditions found deep within Earth and other planetary bodies, enabling researchers to better understand how planets form, evolve, and behave under immense pressures.
As part of the Summer School, SCoPE facilitated two hands-on workshops on June 25 and 26, followed by office hours the following week, to help interns translate their technical research into compelling stories for non-expert audiences. The training focused on identifying the central themes of their work, developing clear and engaging messages, planning effective visitor interactions, and thinking through the logistics of public engagement. Interns also received guidance on preparing both their research posters and individual outreach stations.
The training culminated in two complementary outreach experiences. The first was the FORCE Open House, which welcomed approximately 50 members of the general public for an inside look at the laboratory. Visitors toured the facility, met the research team, explored the specialized equipment used to simulate the interiors of Earth and other planets, and interacted with interns at themed outreach stations designed to explain the science behind the experiments in accessible, engaging ways.
At the second event, a poster session for ASU faculty, staff, and students, the interns presented their research, providing an opportunity to discuss their scientific findings with members of the university community and receive feedback on their presentations.
By integrating science communication training into the Summer School experience, NASA SCoPE helped equip emerging planetary scientists with practical skills for engaging both scientific peers and public audiences. The poster session and Open House demonstrated how thoughtful communication training can strengthen researchers’ confidence while building stronger connections between cutting-edge planetary science and the communities it serves. NASA SCoPE is supported by NASA cooperative agreement award number 80NSSC21M0006 and helps enrich and enhance the impact of the NASA Science Activation Program portfolio, which connects learners with authentic NASA science experiences through partnerships with educators and community organizations.

Data from NASA’s Chandra X-ray Observatory, NASA’s James Webb Space Telescope, and NASA’s Hubble Space Telescope combine to reveal a vibrant view of 30 Doradus, or the Tarantula Nebula, in this Aug. 11, 2026, image. Located in the Large Magellanic Cloud, a small neighbor galaxy to the Milky Way about 160,000 light-years from Earth, the Tarantula has thousands of young stars embedded in a vibrant honeycomb-like structure of gas and dust.
By studying the data from Chandra, Hubble, and Webb, combined with data from the agency’s retired Spitzer Space Telescope, astronomers determined that the Tarantula may be losing energy from several sources, including hot gas escaping from the nebula.

As NASA prepares to establish the Moon Base, advancing surface mobility will be key to helping crews and robotic systems travel farther across the lunar surface.
To help advance that capability, the Rock and Roll with NASA Challenge invited public innovators to design and build next-generation lunar rover wheels.
Five teams from 128 submissions and 49 countries advanced to the final phase of the competition, where they tested their prototypes on July 31 at NASA’s Johnson Space Center in Houston.

The challenge sought lightweight, durable, and scalable wheels that could support longer-duration lunar surface operations. The designs also needed to be compliant enough to absorb impacts, maintain traction at higher speeds, and withstand the harsh lunar environment.
“Every additional kilometer a rover can reliably travel will expand how far we can explore, what science we can achieve, and what infrastructure we can build,” said Ed Herrera, robotics engineer at Johnson and co-leader of the challenge project.
NASA Johnson uses ground prototypes to test mobility technologies, while lunar terrain vehicles will be delivered to the lunar surface through the Commercial Lunar Payload Services initiative. For the challenge, the wheels were fitted to MicroChariot, a 45-kilogram test rover, and put through a series of courses at Johnson’s Rock Yard to evaluate their performance across different types of terrain.

“Crowdsourcing gives us an opportunity to look beyond traditional approaches for lunar wheel design,” Herrera said. “The more wheel technologies we can develop and understand, the more options we have to meet the needs of different vehicles, terrains, and missions on the Moon and Mars.”
Those ideas were reflected in five distinctly different designs.
The HTR Variable Flex Lunar Wheel created by Hellenic Technology of Robotics SA uses an internal system designed to vary the wheel’s stiffness depending on terrain and vehicle needs. The team adapted technology it had been developing for terrestrial wheels for about a decade.
The Hiper Wheel created by Hyperbola uses tensioned cables and a corigated structure that provides spring-like behavior, allowing the wheel to flex without relying on traditional radial spokes.
The Huff Helo Flexible Titanium Wheel created by Huff Helo Inc. uses formed titanium sheet metal as both structure and spring. During testing, the team found that the strength of the design also made the wheel more rigid, causing it to bounce over some obstacles rather than conform to the terrain.
The Payne Aviation Wheel created by Deborah and Craige Payne took inspiration from aviation and history. Its designer, an aircraft mechanic, combined a pneumatic approach with ideas from early automobile tire designs.

The winning Scotch Pad Tyres concept came from an Australian mechanical engineer Daniel Bloomfield and his son Isaac Bloomfield. Their prototype uses a Nomex-based tire structure supported around an aluminum hub. The soft material allows the tire to deform around terrain, while internal support helps it maintain its shape. A treated outer surface of epoxy and corundum grit was integrated to improve traction.
The Rock Yard testing also demonstrated why different terrains may require different approaches. Loose material can affect traction, while rocks and slopes place different demands on wheels such as vehicle stability.

As lunar exploration expands, different vehicles will require different combinations of speed, load capacity, durability, and terrain performance.
Seeking that variety was part of the challenge design. The design options gave engineers different technologies to consider and potentially advance.
“This challenge brought in new ideas from outside traditional industries and helped us identify wheel technologies that may be suitable for longer-duration surface operations,” said Lucien Junkin, robotics engineer at Johnson and co-leader of the challenge project.
The next phase could evaluate how the wheels respond to lunar-like dust, vacuum, and extreme temperatures in Johnson’s thermal vacuum chambers. Engineers could also assess the designs over longer distances and at different sizes and loads.
“Mobility is key to everything we want to do on the Moon,” Junkin said. “The farther we want to explore, the more we need to advance the wheel technologies that can get us there.”
The Common Robotics Project of the Robotic Systems Technology Branch within Johnson’s Engineering Directorate conducted the Rock and Roll with NASA Challenge. NASA’s Center of Excellence for Collaborative Innovation, part of the Prizes, Challenges, and Crowdsourcing Program within the Research and Technology Mission Directorate, managed the challenge contract. Students in NASA’s Robotics Academy helped prepare hardware and support the competition, while engineers from NASA’s Glenn Research Center in Cleveland supported reviews of concepts and proposals. HeroX administered the challenge on behalf of NASA.
