NASA Releases New High-Quality, Near Real-Time Air Quality Data

NASA has made new data available that can provide air pollution observations at unprecedented resolutions – down to the scale of individual neighborhoods. The near real-time data comes from the agency’s TEMPO (Tropospheric Emissions: Monitoring of Pollution) instrument, which launched last year to improve life on Earth by revolutionizing the way scientists observe air quality from space. This new data is available from the Atmospheric Science Data Center at NASA’s Langley Research Center in Hampton, Virginia.

“TEMPO is one of NASA’s Earth observing instruments making giant leaps to improve life on our home planet,” said NASA Administrator Bill Nelson. “NASA and the Biden-Harris Administration are committed to addressing the climate crisis and making climate data more open and available to all. The air we breathe affects everyone, and this new data is revolutionizing the way we track air quality for the benefit of humanity.”

The TEMPO mission gathers hourly daytime scans of the atmosphere over North America from the Atlantic Ocean to the Pacific Coast, and from Mexico City to central Canada. The instrument detects pollution by observing how sunlight is absorbed and scattered by gases and particles in the troposphere, the lowest layer of Earth’s atmosphere.

“All the pollutants that TEMPO is measuring cause health issues,” said Hazem Mahmoud, science lead at NASA Langley’s Atmospheric Science Data Center. “We have more than 500 early adopters using these datasets right away. We expect to see epidemiologists and health experts using this data in the near future. Researchers studying the respiratory system and the impact of these pollutants on people’s health will find TEMPO’s measurements invaluable.”

An early adopter program has allowed policymakers and other air quality stakeholders to understand the capabilities and benefits of TEMPO’s measurements. Since October 2023, the TEMPO calibration and validation team has been working to evaluate and improve TEMPO data products. 

We have more than 500 early adopters that will be using these datasets right away.

“Data gathered by TEMPO will play an important role in the scientific analysis of pollution,” said Xiong Liu, senior physicist at the Smithsonian Astrophysical Observatory and principal investigator for the mission. “For example, we will be able to conduct studies of rush hour pollution, linkages of diseases and health issues to acute exposure of air pollution, how air pollution disproportionately impacts underserved communities, the potential for improved air quality alerts, the effects of lightning on ozone, and the movement of pollution from forest fires and volcanoes.” 

Measurements by TEMPO include air pollutants such as nitrogen dioxide, formaldehyde, and ground-level ozone.

“Poor air quality exacerbates pre-existing health issues, which leads to more hospitalizations,” said Jesse Bell, executive director at the University of Nebraska Medical Center’s Water, Climate, and Health Program. Bell is an early adopter of TEMPO’s data.

Bell noted that there is a lack of air quality data in rural areas since monitoring stations are often hundreds of miles apart. There is also an observable disparity in air quality from neighborhood to neighborhood.

“Low-income communities, on average, have poorer air quality than more affluent communities,” said Bell. “For example, we’ve conducted studies and found that in Douglas County, which surrounds Omaha, the eastern side of the county has higher rates of pediatric asthma hospitalizations. When we identify what populations are going to the hospital at a higher rate than others, it’s communities of color and people with indicators of poverty. Data gathered by TEMPO is going to be incredibly important because you can get better spatial and temporal resolution of air quality across places like Douglas County.”

Determining sources of air pollution can be difficult as smoke from wildfires or pollutants from industry and traffic congestion drift on winds. The TEMPO instrument will make it easier to trace the origin of some pollutants.

“The National Park Service is using TEMPO data to gain new insight into emerging air quality issues at parks in southeast New Mexico,” explained National Park Service chemist, Barkley Sive. “Oil and gas emissions from the Permian Basin have affected air quality at Carlsbad Caverns and other parks and their surrounding communities. While pollution control strategies have successfully decreased ozone levels across most of the United States, the data helps us understand degrading air quality in the region.” 

The TEMPO instrument was built by BAE Systems, Inc., Space & Mission Systems (formerly Ball Aerospace) and flies aboard the Intelsat 40e satellite built by Maxar Technologies. The TEMPO Ground System, including the Instrument Operations Center and the Science Data Processing Center, are operated by the Smithsonian Astrophysical Organization, part of the Center for Astrophysics | Harvard & Smithsonian.

NASA Updates Coverage for Boeing’s Starliner Launch, Docking

NASA will provide live coverage of prelaunch and launch activities for the agency’s Boeing Crew Flight Test, which will carry NASA astronauts Butch Wilmore and Suni Williams to and from the International Space Station.

Launch of the ULA (United Launch Alliance) Atlas V rocket and Boeing Starliner spacecraft is targeted for 12:25 p.m. EDT Saturday, June 1, from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. Starliner will dock to the forward-facing port of the station’s Harmony module at approximately 1:50 p.m., Sunday, June 2.

Wilmore and Williams will remain at the space station for about a week to test the Starliner spacecraft and its subsystems before NASA works to complete final certification of the transportation system for rotational missions to the orbiting laboratory as part of the agency’s Commercial Crew Program.

NASA, Boeing, and ULA scrubbed the previous launch opportunity on May 6 due to a suspect oxygen relief valve on the Atlas V rocket’s Centaur second stage. Since, teams have removed and replaced the valve, and completed an assessment of Starliner’s performance and redundancy after discovering a small helium leak in the spacecraft’s service module.

As part of the helium leak investigation, NASA and Boeing conducted a follow-on propulsion system assessment to understand potential helium system impacts to some Starliner return scenarios. NASA also completed a Delta-Agency Flight Test Readiness Review on May 29 to evaluate all work performed and flight rationale before proceeding toward launch.

The Moon and Amaey Shah

8 Min Read

The Moon and Amaey Shah

Sometimes a story about a NASA volunteer just grabs your heart and won’t let go. NASA Scientist Dr. Brian Day shared with us the incredible story of what first ignited his passion for involving the public in his scientific research. It’s a story about a boy named Amaey Shah.

“Through the NASA Speakers Bureau, I was paired with a local teacher, Leslie Herleikson, and her after-school science program for K-12 students” Brian began.  “I’d talk to the students in the program periodically and take them on tours of the NASA Ames facilities.”  

“One of the kids in Leslie’s elementary program, a young boy named Amaey Shah, was recovering from treatment for childhood leukemia when I first met him. He was feeling fatigued from the treatment. As we did the tours of Ames he sometimes had to rest.  But he was a very precocious kid. He remained very excited about science, posing a rapid stream of very insightful questions, and always full of joyous enthusiasm for the new things that he would learn.  

Over time, Amaey rallied and his strength improved, fueled by his insatiable curiosity. I continued to meet with Amaey and his fellow students, with our discussions spanning the Solar System and beyond.

Then, one day, I showed up at the after-school program and Amaey was not there. Leslie took me aside after my presentation and let me know that Amaey had had a relapse which seemed pretty serious. He was going to need a bone marrow transplant. This news hit me especially hard. Shortly before the class meeting, I had been diagnosed with cancer myself.  Just as Amaey was going to be heading in for whole body radiation as part of his bone marrow transplant, I was going to be going in for radiation for my own cancer treatment.  

Leslie shared my situation with Amaey and his parents. She also asked if I would be willing to come talk with him about our upcoming shared experience.  The idea seemed strangely comforting and healthy. So I showed up at his house. Amaey and I sat down together, with his parents and older brother sitting off to the side in the same room.  

I said: Well, I understand we have something in common.

He said, Well, we both like science!

I said: That’s true.

He said: And we both wear glasses.

I said:  Yes.

Then, I said: And we’re both incredibly handsome!

We all had a good laugh. But then he looked at me and got serious. 

He said: And we both have cancer.

I said: Yes, and we’re both going to get radiation.

And he said: Yeah.

So I said: How do we feel about that?

He told me what was bothering him most. He said that in his case, the radiation was to kill all of his bone marrow, and hopefully the cancer that was within it.  Then he would get a transplant of new bone marrow.  But during the period of time in between losing his old bone marrow and when his new bone marrow kicked in, he would essentially be without an immune system. He would become a bubble boy—confined to a room for a very long period of time.  He expressed that he was really going to miss going out and exploring, going out and looking up at the night sky, because one of the things he really, really wanted to do was explore space.

I’d been given a warning about this from his parents, so I’d come prepared with my laptop. I pulled up MoonZoo.  MoonZoo was a citizen science application that asked people to look at pieces of lunar real estate and identify and count craters. Crater counts are the primary way of estimating the ages of various lunar terrains. If we want to understand the history and evolution of the lunar surface, getting these crater counts and the ages they represent is a really critical endeavor.

Amaey was quite excited to work on MoonZoo.  We played with that for a long while!  Then I pulled up GalaxyZoo, another Zooniverse project. 

We reviewed the fact that galaxies come in a great variety of sizes and shapes.  And we see a mind-bending number of galaxies out there. To understand their formation and evolution, we must first understand what kinds of galaxies they are. So, we need people to help classify these galaxies—which involves looking at a lot of galaxies.  Amaey really liked that too.

We went into our respective cancer treatments. Amaey did indeed become confined in isolation after his irradiation and transplant—but I heard from his teacher Leslie that from his room he was keeping himself busy exploring the Moon, counting craters with MoonZoo, and classifying galaxies with GalaxyZoo.  Even though Amaey was physically confined to his room, his intellect and curiosity were free to roam the Solar System and the Universe, exploring limitless expanses, thanks to the citizen science tools that he put to such good use. Soon, I got distracted with my own treatment, and I wasn’t online as much as I would have liked to have been.  

As I was going through my own treatment, I didn’t get the news. Amaey’s treatment didn’t work. His parents and teachers opted not to tell me that he had passed away while I was in the midst of fighting my own battle.

The day after I successfully finished my final radiation treatment, I remember talking to Leslie on the phone. I told her that I was done, and I wanted to come talk to the kids again as soon as I was feeling a bit stronger. She said she had something to tell me. She let me know that Amaey had passed away.  I was devastated. 

Leslie also told me that Amaey’s funeral service was coming up soon. Amaey’s parents then contacted me, asking me if I might be feeling well enough to come speak at the service. I had to go. There was no way I could not be there!  

There were many people gathered together at the service and several speakers. At one point, Amaey’s grandfather got up and in a quiet, sorrowful way, explained how Amaey’s desire had always been to be a scientist. Amaey had wanted to study the stars, do research, and contribute. One of the great sadnesses of the grandfather’s own life was that Amaey never had the opportunity to become a scientist, to explore the Universe, and to contribute to the science like he had so loved.  

Then it was my turn to speak. I stood up, and I said that I mean no disrespect—I fully understood the sorrow that the family was feeling.  But the very important fact of the matter was that Amaey did not miss this opportunity! Amaey HAD realized his dream. He DID become a scientist. From his isolation room, Amaey DID explore. He DID do research. He DID make contributions. Amaey’s ambitions had been realized, and his discoveries had been added to the scientific record.

I said we can all take heart in knowing that under very difficult circumstances Amaey had achieved his dream.  That seemed to become a source of comfort to Amaey’s family. And that’s because he stepped up to the role and adventure of being a citizen scientist.”

Brian Day is the staff scientist at NASA’s Solar System Exploration Research Virtual Institute, headquartered at NASA’s Ames Research Center in California. His duties include serving as science lead for NASA’s Solar System Treks Project a family of open science online portals that make it easy to analyze the surfaces of the Moon and other planetary bodies in our Solar System. The project has a citizen science component called MoonDiff, which invites you to help search for changes and newly formed features on the Moon.

You can make your own contributions to science! Check out Brian’s project, MoonDiff. And if you know any other children like Amaey, please share it with them.

Webb Spots a Starburst

The James Webb Space Telescope observed “starburst” galaxy NGC 4449, seen in this image released on May 29, 2024. Starbursts are intense periods of star formation usually concentrated at a galaxy’s core, but NGC 4449’s activity is much more widespread — likely due to past interactions with its galactic neighbors. Astronomers can study this galaxy to look into the past: NGC 4449 is similar to early star-forming galaxies, which also grew by merging with other systems.

NASA Welcomes Peru as 41st Artemis Accords Signatory

NASA Administrator Bill Nelson welcomed Peru as the newest nation to sign the Artemis Accords Thursday during a ceremony with the U.S. State Department at NASA Headquarters in Washington. Peru joins 40 other countries in a commitment to advancing principles for the safe, transparent, and responsible exploration of the Moon, Mars and beyond.

“NASA is proud to welcome Peru to the Artemis Accords family,” said Nelson. “This giant leap forward for our countries is a result of decades of work Peru has done to further its reach in the cosmos. We live in the golden era of space exploration. Together, we will continue to explore the cosmos openly, responsibly, as partners, for all.”

Javier González-Olaechea, foreign minister, signed the Artemis Accords on behalf of Peru. Alfredo Ferrero Diez Canseco, ambassador of Peru to the U.S. and Jennifer R. Littlejohn, acting assistant secretary, Bureau of Oceans and International Environmental and Scientific Affairs, Department of State, also participated in the signing ceremony.

“Peru, by joining the Artemis Accords, seeks not only to express a common vision with the other member countries but also to establish cooperation mechanisms with these countries, especially with the United States, to participate in activities of exploration and sustainable use of resources found in space, as well as to promote aerospace scientific development in our country,” said González-Olaechea.

The United States and seven other nations were the first to sign the Artemis Accords in 2020, which identified an early set of principles promoting the beneficial use of space for all humanity. The accords are grounded in the Outer Space Treaty and other agreements including the Registration Convention, the Rescue and Return Agreement, as well as best practices and norms of responsible behavior that NASA and its partners have supported, including the public release of scientific data. More countries are expected to sign the Artemis Accords in the months and years to come.

The commitments of the Artemis Accords, and efforts by the signatories to advance implementation of these principles, support NASA’s Artemis campaign with its partners, as well as for the success of the safe and sustainable exploration activities of the other accords signatories.
