Science Activation’s PLACES Team Facilitates Second Professional Learning Institute
The NASA Science Activation Program’s Place-Based Learning to Advance Connections, Education, and Stewardship (PLACES) team successfully led their second Professional Learning (PL) Summer Institute (SI) at Northern Arizona University (NAU) in Flagstaff, Arizona from June 11-13, 2024. The team led a group of 13 educators through a variety of powerful place-based data-rich (PBDR) experiences across the three-day SI. PL kicked off with teachers engaging in an intensive field experience at Hat Ranch that leveraged the ecological expertise of NAU’s subject matter expert, Jared Litson Begay, and using data collection protocols from the NASA-sponsored program, GLOBE (Global Learning and Observations to Benefit the Environment) to better understand piñon pine populations in Flagstaff ecosystems. Following this, teachers moved from their primary data collection experiences to exploring secondary data that expanded on the piñon pine focus by leveraging data and the Data Literacy Cubes from My NASA Data (MND).
Using and reflecting on GLOBE protocols created powerful conversations where teachers saw how place influenced how they engaged in data collection and how data can help develop new place-based knowledge and connections in their contexts. One teacher even shared that “collecting data using the GLOBE app and making observations about data helped me better understand how I can use these practices with my students.” The MND data and Data Literacy Cubes offered educators the pathways to move from their primary data collection experiences to ask and answer new and exciting questions.
In the follow-up survey, teachers shared that they are interested in exploring “additional resources from NASA,” using “local experts or data for small town/rural areas through NASA,” and implementing PBDR instruction using NASA assets in the coming months. 100% of teachers who were surveyed after the PL indicated (1) they agree or strongly agree that they feel greater connection to NASA and knowledge of NASA assets, and (2) they would recommend the PLACES PL to a colleague. In the coming months, the teachers will participate in a virtual Community of Practice where they will implement PBDR experiences in their own contexts, share examples of student work, and elicit feedback from one another to continue improving their practice.
The PLACES team would like to give a huge shout-out to those who contributed to planning, developing, and implementing the NAU Summer Institute!

4 Min Read NASA Celebrates 20 Years of Earth-Observing Aura Satellite
The Aura spacecraft, shown in this artist’s concept, is a NASA atmospheric chemistry mission that monitors Earth’s protective atmosphere. Credits:
NASA Earth (ESD) Earth Home Explore Climate Change Science in Action Multimedia Data For Researchers From monitoring the hole in the ozone above the Antarctic to studying air quality around the entire planet, NASA’s Aura satellite has provided scientists with essential measurements during its two decades in orbit.
“The Aura mission has been nothing short of transformative for scientific research and applied sciences,” said Bryan Duncan, project scientist for NASA’s Aura satellite mission. “The mission’s data have given scientists and applied scientists an unparalleled view of air pollution around the world.”
Aura has revealed the effects of industrialization, environmental regulations, wildfires, the COVID-19 pandemic, and many other aspects of the air we breathe. The satellite paved the way for recent missions to study the atmosphere and its inner workings, including PACE and TEMPO. As the Aura mission team celebrates its launch anniversary of July 15, 2004, here are a few of the many highlights from the last 20 years.
Aura Eyes Ozone Hole over Antarctica
The first publicly released image from the Aura mission (autumn 2004) showed dramatically depleted levels of ozone in the stratosphere over Antarctica.
NASA Study: First Direct Proof of Ozone Hole Recovery Due to Chemicals Ban
In a 2018 study, scientists showed for the first time through direct satellite observations that levels of chlorine in the atmosphere declined, resulting in less ozone depletion. Because of an international ban on chlorine-containing manmade chemicals called chlorofluorocarbons, there was about 20% less ozone depletion during the Antarctic winter in 2016 than there was in 2005.
New NASA Satellite Maps Show Human Fingerprint on Global Air Quality
This global map shows the concentration of nitrogen dioxide in the troposphere as detected by the Ozone Monitoring Instrument aboard the Aura satellite, averaged over 2014. NASA Using high-resolution global maps of air quality indicators made with data from the Aura satellite, NASA scientists tracked air pollution trends between 2005 and 2015 in various regions and 195 cities around the globe. The study found that the United States, Europe, and Japan saw improved air quality due to emission control regulations, while China, India, and the Middle East, with their fast-growing economies and expanding industry, saw more air pollution.
How NASA is Helping the World Breathe More Easily
Many of NASA’s Earth-observing satellites, including Aura, can see what the human eye can’t — including potentially harmful pollutants lingering in the air we breathe. These satellites help us measure and track air pollution as it moves around the globe and have contributed significantly to a decades-long quest for cleaner air. For example, data from Aura’s Ozone Monitoring Instrument helped the EPA and NASA identify a drop in nitrogen dioxide that researchers cited as evidence of the success of the Clean Air Act.
Air Quality: A Tale of Three Cities
Air quality in Beijing, Los Angeles, and Atlanta — like air quality across the globe — is dynamic. This video describes how scientists use instruments like Aura’s Ozone Monitoring Instrument to study questions including what causes ozone, sulfur dioxide, and nitrogen dioxide emissions. It also explores why reductions in volatile organic carbon pollution worked to reduce ground-level ozone in Los Angeles, but not in Atlanta.
Seeing the COVID-19 Pandemic from Space
Economic and social shutdowns in response to the COVID-19 pandemic led to noticeable changes in Earth’s environment, at least in the short term. NASA researchers used satellite and ground-based observations – including nitrogen dioxide levels from Ozone Monitoring Instrument – to track these impacts on our air, land, water, and climate.
A Satellite’s View of Ship Pollution
With natural-color satellite imagery of the atmosphere over the ocean, scientists have observed “ship tracks” — bright, linear trails amidst the cloud layers that are created by particles and gases from ships. Scientists used Ozone Monitoring Instrument data to detect the almost invisible tracks of nitrogen dioxide along several shipping routes from 2005 to 2012.
First Global Maps of Volcanic Emissions Use NASA Satellite Data
Volcanic sulfur dioxide emissions from Indonesia’s many volcanoes are shown in shades of orange. The data was produced from observations from NASA’s Aura satellite. With the Ozone Monitoring Instrument data, researchers compiled emissions data from 2005 to 2015 create the first global inventory for volcanic sulfur dioxide emissions. The data set helped refine climate and atmospheric chemistry models and provided more insight into human and environmental health risks.
Scientists Show Connection Between Gas Flaring and Arctic Pollution
Flaring of excess natural gas from industrial oil fields in the Northern Hemisphere was found to be a potentially significant source of nitrogen dioxide and black carbon emissions polluting the Arctic, according to a 2016 NASA study that included data from Aura.
2023 Ozone Hole Ranks 16th Largest, NASA and NOAA Researchers Find
Researchers continue to rely on Aura data to monitor the Antarctic ozone hole, two decades after the satellite launched. Each Southern Hemisphere spring, NASA and NOAA (National Oceanic and Atmospheric Administration) use satellite and balloon-based measurements to measure the maximum size of the ozone hole. The story above notes the 2023 result; stay tuned for what Aura helps us discover in 2024 and beyond.
This map shows the size and shape of the ozone hole over the South Pole on Sept. 21, 2023, the day of its maximum extent that year, as calculated by the NASA Ozone Watch team.

NASA 55 years ago on July 16, 1969, NASA’s Apollo 11 spacecraft launched from the agency’s Kennedy Space Center in Florida, as seen in this photo. Astronauts Neil Armstrong, Michael Collins, and Buzz Aldrin were aboard.
Apollo 11’s primary mission objective was to fulfill a national goal set by President John F. Kennedy on May 25, 1961: perform a crewed lunar landing and return safely to Earth before the decade ended. Additional flight objectives included scientific exploration by the lunar module (LM) crew, deployment of a television camera to transmit signals to Earth, and deployment of a solar wind composition experiment, seismic experiment package, and a Laser Ranging Retroreflector. During the exploration, Armstrong and Aldrin were to gather samples of lunar-surface materials for return to Earth. They also were to extensively photograph the lunar terrain, the deployed scientific equipment, the LM spacecraft, and each other, both with still and motion picture cameras.
