NASA’s Earth Observatory United States embassies and consulates, along with American citizens traveling and living abroad, now have a powerful tool to protect against polluted air, thanks to a collaboration between NASA and the U.S. State Department.
Since 2020, ZephAir has provided real-time air quality data for about 75 U.S. diplomatic posts. Now, the public tool includes three-day air quality forecasts for PM2.5, a type of fine particulate matter, for all the approximately 270 U.S. embassies and consulates worldwide. These tiny particles, much smaller than a grain of sand, can penetrate deep into the lungs and enter the bloodstream, causing respiratory and cardiovascular problems.
“This collaboration with NASA showcases how space-based technology can directly impact lives on the ground,” said Stephanie Christel, climate adaptation and air quality monitoring program lead with the State Department’s Greening Diplomacy Initiative. “This is not something the State Department could have done on its own.” For instance, placing air quality monitors at all U.S. diplomatic posts is prohibitively expensive, she explained.
“NASA’s involvement brings not only advanced technology,” she added, “but also a trusted name that adds credibility and reliability to the forecasts, which is invaluable for our staff stationed abroad.”
The forecasts, created using NASA satellite data, computer models, and machine learning, are crucial for U.S. embassies and consulates, where approximately 60,000 U.S. citizens and local staff work. Many of these sites are in regions with few local air quality monitors or early warning systems for air pollution.
“ZephAir’s new forecasting capability is a prime example of NASA’s commitment to using our data for societal benefit,” said Laura Judd, an associate program manager for Health and Air Quality at NASA. “Partnering with the State Department allows us to extend the reach of our air quality data, providing embassies and local communities worldwide with vital information to protect public health.”
Enhancing Health, Safety with NASA Air Quality Data
To manage air pollution exposure, the tool can assist diplomatic staff with decisions on everything from building ventilation to outdoor activities at embassy schools.
For many embassies, especially in regions with severe air pollution, having reliable air quality forecasts is crucial for safeguarding staff and their families, influencing both daily decisions and long-term planning. “Air quality is a top priority for my family as we think about [our next assignment], so having more information is a huge help,” said Alex Lewis, a political officer at the U.S. embassy in Managua, Nicaragua.

U.S. Department of State Previously, ZephAir only delivered data on current PM2.5 levels using air quality monitors on the ground from about 75 U.S. diplomatic locations and about 50 additional sources. Now, the enhanced tool provides PM2.5 forecasts for all sites, using the Goddard Earth Observing System forward processing (GEOS-FP), a weather and climate computer model. It incorporates data on tiny particles or droplets suspended in Earth’s atmosphere called aerosols from MODIS (Moderate-resolution Imaging Spectroradiometer) on NASA’s Terra and Aqua satellites.
Aerosols are tiny airborne particles that come from both natural sources, like dust, volcanic ash, and sea spray, and from human activities, such as burning fossil fuels. PM2.5 refers to particles or droplets that are 2.5 micrometers or smaller in diameter — about 30 times smaller than the width of a human hair.
“We use the GEOS-FP model to generate global aerosol forecasts,” said Pawan Gupta, of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and the lead scientist on the project. “Then we calibrate the forecasts for embassy locations, using historical data and machine learning techniques.”
As of August 2024, the forecasting feature is available on the ZephAir web and mobile platforms.
The new forecasts are about more than just protecting U.S. citizens and local embassy staff; they are also contributing to global action on air quality. The State Department engages with local governments and communities to raise awareness about air quality issues. “These forecasts are a critical part of our strategy to mitigate the impacts of air pollution not only for our personnel but also for the broader community in many regions around the world,” Christel said.
Officials with the Greening Diplomacy Initiative partnered with NASA through the Health and Air Quality Applied Sciences Team to develop the new forecasts and will continue the collaboration through support from the Satellite Needs Working Group.
Looking ahead, the team aims to expand ZephAir’s capabilities to include ground-level ozone data, another major pollutant that can affect the health of embassy staff and local communities.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NAACP Board Chair Leon Russell, left, and NASA Administrator Bill Nelson, right, sign a Space Act Agreement between NASA and the NAACP during a 5th Annual Hidden Figures Street Naming Anniversary event Thursday, Sept. 19, 2024, at the Mary W. Jackson NASA Headquarters building in Washington. NASA/Keegan Barber During an event Thursday, NASA and the National Association for the Advancement of Colored People (NAACP) signed a Space Act Agreement to increase engagement and equity for underrepresented students pursuing science, technology, engineering, and mathematics (STEM) fields and to improve access to agency activities and opportunities.
“NASA and the NAACP share a longstanding commitment to attracting more diverse students to STEM education and ultimately careers,” said Shahra Lambert, senior advisor for engagement and equity, NASA headquarters. “This agreement reaffirms that commitment and solidifies a partnership that will enable us to expand opportunities for more students of color to build their STEM identity and gain real-world experience through NASA STEM education, mentorship, and career awareness. With the NAACP’s help we’ll be able to truly impact young minds who will be our future scientists, engineers, explorers and more.”
As part of the agreement, the NAACP will incorporate NASA STEM lessons, content, and themes into its Afro-Academic, Cultural, Technological and Scientific Olympics (ACT-SO) achievement program, which is a series of competitions where students compete for scholarships and other incentives in areas ranging from performing and culinary arts to business and STEM. In turn, NASA will provide guidance on programming, participate in information sharing, provide mentorship, and facilitate tours of NASA facilities when appropriate.
“Much like NASA, brave, brilliant, Black women were critical to the success of the NAACP,” said Leon W. Russell, Chairman of the NAACP Board of Directors. “For years, we’ve worked to increase the number of diverse STEM students by providing scholarships and establishing key initiatives. Through our ACT-SO program and this new partnership with NASA, both organizations will make even greater progress to help pave the way for more Katherine Johnsons and Mary Jacksons. By enacting today’s agreement, we hope to increase the number of Black and underrepresented students in the STEM fields and help them reach for the stars.”
While initial efforts will be led by NASA’s Office of STEM Engagement, the umbrella agreement also allows for further collaboration and partnership in the future. Specifically, the agency and the NAACP will look to support certain areas of NASA’s Equity Action Plan.
NASA works to explore the secrets of the universe and solve the world’s most complex problems, which requires creating space for all people to participate in and learn from its work in space. Providing access to opportunities where young minds can be curious and see themselves potentially at NASA and beyond is how the agency will continue to inspire the next generation of STEM innovators.

4 Min Read NASA’s Hidden Figures Honored with Congressional Gold Medals
Sen. Shelly Moore Capito (R-WV), delivers remarks during a Congressional Gold Medal ceremony recognizing NASA’s Hidden Figures, Wednesday, Sept. 18, 2024, in Emancipation Hall at the U.S. Capitol in Washington. Credits: NASA/Joel Kowsky A simple turn of phrase was all it took for U.S. Sen. Shelley Moore Capito of Katherine Johnson’s home state of West Virginia to capture the feeling in Emancipation Hall at the U.S. Capitol in Washington.
“It’s been said that Katherine Johnson counted everything,” she said. “But today we’re here to celebrate the one thing even she couldn’t count, and that’s the impact that she and her colleagues have had on the lives of students, teachers, and explorers.”
That sense of admiration and awe toward the legacy and impact of NASA’s Hidden Figures was palpable Wednesday during a Congressional Gold Medal Ceremony to honor the women’s work and achievements during the space race.
The Congressional Gold Medal in recognition of Katherine Johnson in recognition of her service to the United States as a Mathematician is seen during a ceremony recognizing NASA’s Hidden Figures, Wednesday, Sept. 18, 2024, in Emancipation Hall at the U.S. Capitol in Washington. Katherine Johnson’s family accepted this gold medal on her behalf.NASA/Joel Kowsky The ceremony, hosted by House Speaker Mike Johnson, honored Johnson, Dorothy Vaughan, Mary Jackson, and Dr. Christine Darden of NASA’s Langley Research Center in Hampton, Virginia, along with all the other women who served at the agency and its precursor, the National Advisory Committee for Aeronautics, or the NACA, as computers, mathematicians, and engineers.
“The pioneers we honor today, these Hidden Figures — their courage and imagination brought us to the Moon. And their lessons, their legacy, will send us back to the Moon,” said NASA Administrator Bill Nelson.
Margot Lee Shetterly, whose 2016 nonfiction book “Hidden Figures: The American Dream and the Untold Story of the Black Women Who Helped Win the Space Race,” brought awareness to the stories of NASA’s human computers, spoke at the event.NASA/Joel Kowsky Author Margot Lee Shetterly detailed the stories of the women from NASA Langley in her 2016 nonfiction book “Hidden Figures: The American Dream and the Untold Story of the Black Women Who Helped Win the Space Race.” Though the book focused on NASA Langley, where Shetterly’s father worked, it helped raise awareness of similar stories around NASA.
A film adaptation of the book starring Taraji Henson as Johnson, Octavia Spencer as Vaughan, and Janelle Monáe as Jackson came out later that year and further elevated the topic. NASA participated under a Space Act Agreement with 20th Century Fox in activities around the movie, to provide historical guidance and advice during the filmmaking process.
In her remarks, Shetterly noted that even as the Hidden Figures made such key contributions to NASA and the NACA before it, they remained active in their communities, leading Girl Scout troops and delivering meals to the hungry.
“They spent countless hours tutoring kids so that those kids, too, would see the power and the beauty of numbers they believed in, tending to the small D democracy that binds us to each other as neighbors and as American citizens,” she said.
The medal citations were as follows:
Congressional Gold Medal to Katherine Johnson, in recognition of her service to the United States as a mathematician Congressional Gold Medal to Dr. Christine Darden, for her service to the United States as an aeronautical engineer Congressional Gold Medals in commemoration of the lives of Dorothy Vaughan and Mary Jackson, in recognition of their service to the United States during the space race Congressional Gold Medal in recognition of all the women who served as computers, mathematicians, and engineers at the National Advisory Committee Family members of Johnson, Vaughn, Jackson and Dr. Darden accepted medals on their behalves. Dr. Darden watched the ceremony from home.
House Speaker Mike Johnson and Andrea Mosie, senior Apollo sample processor and lab manager who oversees the 842 pounds of Apollo lunar samples. Mosie accepted the medal awarded in recognition of all the women who served as computers, mathematicians, and engineers at the National Advisory Committee for Aeronautics and NASA between the 1930s and the 1970s.NASA/Joel Kowsky Andrea Mosie, senior Apollo sample processor and lab manager who oversees the 842 pounds of Apollo lunar samples, accepted the medal awarded to all NASA’s Hidden Figures. She began her career at NASA’s Johnson Space Center in Houston in the 1970s.
Mosie thanked Congress for supporting NASA’s campaign to send the first woman and first person of color to the Moon as part of Artemis and the agency’s efforts to provide “opportunities for people, more representative of the way our country looks, to understand humanity’s place in the universe.”
Several NASA Langley officials attended the event to honor the legacies of the women who worked there.
“I am humbled by the significant contributions and lasting impact of these women to America’s aeronautics and space programs. Their brilliance and perseverance still echo not just through the halls of NASA Langley, but through the entire Agency,” said NASA Langley’s Acting Center Director Dawn Schaible. “They are an inspiration to me and countless others who have benefited from the paths they forged.”
Rep. Eddie Bernice Johnson of Texas, who passed away in 2023, introduced H.R. 1396 – Hidden Figures Congressional Gold Medal Act on Feb. 27, 2019. It was signed into law later that year.
In 2015, President Barack Obama presented Katherine Johnson with the Presidential Medal of Freedom, the nation’s highest civilian honor.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
SpaceX Crew-9 members (from left) Mission Specialist Aleksandr Gorbunov from Roscosmos and Commander Nick Hague from NASA pose for an official crew portrait at NASA’s Johnson Space Center in Houston, Texas.NASA/Josh Valcarel NASA astronaut Nick Hague and Roscosmos cosmonaut Aleksandr Gorbunov are preparing to launch on the agency’s SpaceX Crew-9 mission to the International Space Station.
The flight is the ninth crew rotation mission with SpaceX to the station under NASA’s Commercial Crew Program. The duo will lift off aboard the SpaceX Dragon spacecraft, which previously flew NASA’s SpaceX Crew-4, Axiom Mission 2 and Axiom Mission 3, from Launch Complex 40 at Cape Canaveral Space Force Station in Florida.
Once aboard the space station, Hague and Gorbunov will become members of the Expedition 72 crew and perform research, technology demonstrations, and maintenance activities. The pair will join NASA astronauts Don Petitt, Butch Wilmore, Suni Williams, as well as Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner.
Wilmore and Williams, who launched aboard the Starliner spacecraft in June, will fly home with Hague and Gorbunov in February 2025.
Launch preparations are underway, and teams are working to integrate the spacecraft and the SpaceX Falcon 9 rocket, including checkouts of a second flight rocket booster for the mission. The integrated spacecraft and rocket will then be rolled to the pad and raised to the vertical position for a dry dress rehearsal with the crew and an integrated static fire test prior to launch.
The Crew
Nick Hague will serve as crew commander for Crew-9, making this his third launch and second mission to the space station. During his first launch in October 2018, Hague and his crewmate, Roscosmos’ Alexey Ovchinin, experienced a rocket booster failure, resulting in an in-flight, post-launch abort, ballistic re-entry, and safe landing in their Soyuz MS-10 spacecraft. Five months later, Hague launched aboard Soyuz MS-12 and served as a flight engineer aboard the space station during Expeditions 59 and 60. Hague has spent 203 days in space and conducted three spacewalks to upgrade space station power systems and install a docking adapter for commercial spacecraft.
Born in Belleville, Kansas, Hague earned a bachelor’s degree in Astronautical Engineering from the United States Air Force Academy and a master’s degree in Aeronautical and Astronautical Engineering from the Massachusetts Institute of Technology in Cambridge, Massachusetts. Hague was selected as an astronaut by NASA in 2013. An active-duty colonel in the U.S. Space Force, Hague completed a developmental rotation at the Defense Department and served as the Space Force’s director of test and evaluation from 2020 to 2022. In August 2022, Hague resumed duties at NASA, working on the Boeing Starliner Program until this flight assignment.

Roscosmos cosmonaut Aleksandr Gorbunov will embark on his first trip to the space station as a mission specialist for Crew-9. Born in Zheleznogorsk, Kursk region, Russia, he studied engineering with qualifications in spacecraft and upper stages from the Moscow Aviation Institute. Gorbunov graduated from the military department with a specialty in operating and repairing aircraft, helicopters, and aircraft engines. Before his selection as a cosmonaut in 2018, he worked as an engineer for Rocket Space Corp. Energia and supported cargo spacecraft launches from the Baikonur Cosmodrome. Gorbunov will serve as a flight engineer during Expedition 71/72 aboard the space station.
Mission Overview
After liftoff, Dragon will accelerate to approximately 17,500 mph to dock with the space station.
Once in orbit, flight control teams from NASA’s Mission Control Center at the agency’s Johnson Space Center in Houston and the SpaceX mission control in Hawthorne, California, will monitor a series of automatic maneuvers that will guide Dragon to the forward-facing port of the station’s Harmony module. The spacecraft is designed to dock autonomously, but the crew can take control and pilot manually if necessary.
After docking, Expedition 71 will welcome Hague and Gorbunov inside the station and conduct several days of handover activities with the departing astronauts of NASA’s SpaceX Crew-8 mission. After a handover period, NASA astronauts Matthew Dominick, Michael Barratt, Jeanette Epps, and Roscosmos cosmonaut Alexander Grebenkin of Crew-8 will undock from the space station and splash down off the coast of Florida.
Crew-9 will conduct new scientific research to prepare for human exploration beyond low Earth orbit and benefit humanity on Earth. Experiments include the impact of flame behavior on Earth, studying cells and platelets during long-duration spaceflight, and a B vitamin that could reduce Spaceflight-Associated Neuro-ocular Syndrome. They’ll also work on experiments that benefit life on Earth, like studying the physics of supernova explosions and monitoring the effects of different moister treatments on plants grown aboard the station. These are just a few of over 200 scientific experiments and technology demonstrations taking place during their mission.
While aboard the orbiting laboratory, Crew-9 will welcome two Dragon spacecraft, including NASA’s SpaceX’s 31st commercial resupply services mission and NASA’s SpaceX Crew-10, and two Roscosmos-led cargo deliveries on Progress 90 and 91.
In February, Hague, Gorbunov, Wilmore, and Williams will climb aboard Dragon and autonomously undock, depart the space station, and re-enter Earth’s atmosphere. After splashdown off Florida’s coast, a SpaceX recovery vessel will pick up the spacecraft and crew, who then will be helicoptered back to shore.
Commercial crew missions enable NASA to maximize use of the space station, where astronauts have lived and worked continuously for more than 23 years testing technologies, performing research, and developing the skills needed to operate future commercial destinations in low Earth orbit, and explore farther from Earth. Research conducted on the space station provides benefits for people on Earth and paves the way for future long-duration trips to the Moon and beyond through NASA’s Artemis missions.
