Science Activation’s PLACES Team Facilitates Third Professional Learning Institute
The NASA Science Activation program’s Place-Based Learning to Advance Connections, Education, and Stewardship (PLACES) project supports middle and high school educators to engage students in data-rich Earth science learning through the integration of NASA data sets, images, classroom lessons, and other assets. This project draws on a place-based approach as a means to increase “data fluency” — the ability and confidence to make sense of and use data. This means knowing when, how, and why to use data for a specific purpose, such as solving problems and communicating ideas grounded in evidence.
As part of this effort, PLACES facilitated its third Professional Learning (PL) Summer Institute (SI) for 22 educators at the Gulf of Maine Research Institute (GMRI) in Portland, Maine the week of August 12th, 2024. This is the third PL Summer Institute the PLACES team has facilitated, each focusing on engaging educators in place-based, data-rich teaching and learning with NASA data and resources.
The GMRI PL development and facilitation was a collaborative co-design effort between two NASA Science Activation projects (PLACES led by WestEd and the Learning Ecosystems Northeast project led by GMRI) and colleagues from the Concord Consortium and NASA Langley Research Center. During this PL, teachers took part in community science projects developed by GMRI to incorporate youth in ongoing research projects, including a mix of field- and classroom-based experiences that explored the phenomena of Hemlock Woolly Adelgid (HWA) and the changes to intertidal crab populations – two invasive species that are proliferating as a result of climate change. During two field-based experiences, teachers gathered primary data using protocols from GMRI’s Ecosystem Investigation Network and the NASA-sponsored program, GLOBE (Global Learning and Observations to Benefit the Environment). Teachers then explored these primary data using Concord Consortium’s Common Online Data Analysis Platform (CODAP) to better understand the geographic and temporal spread of these species. To connect their local experiences to global happenings, teachers then explored secondary data sets, including those sourced from the My NASA Data (MND – also supported by NASA Science Activation as part of the GLOBE Mission Earth project) Earth System Explorer (e.g., Normalized Difference Vegetation Index, salinity, sea surface temperature). The facilitation team also used the MND Data Literacy Cubes to encourage teachers to consider a multitude of diverse questions about place, data, and the phenomena. The GLOBE protocols supplemented existing GMRI data collection protocols, presenting new opportunities for teachers already experienced with HWA and Green Crabs. The MND data and Data Literacy Cubes moved teachers from questions they generated as part of their primary data collection towards new knowledge.
Daily feedback from teachers highlighted their appreciation for the responsiveness of the facilitation team, as well as a growing curiosity and desire for using NASA resources such as protocols from GLOBE and data from MND’s Earth System Explorer. This is exciting to see as the teachers transition from the Summer Institute into a virtual Community of Practice during the school year. The Community of Practice engages them in peer-to-peer collaboration and dialogue as they develop, test, and give feedback on their own place-based, data-rich experiences using NASA data and resources. So far, teachers are planning to tackle a variety of topics ranging from ocean chemistry to human connections to the environment. Teachers indicated their interest in “making place-based experiences meaningful to our unique populations of students and having cultural representation in the classroom,” and focusing on “cross-school collaboration.” Preliminary evaluation data indicated that 76% of teachers thought their experiences with NASA resources during the SI helped them identify ways to bring data into their classroom. 85% of teachers indicated they feel a greater connection to NASA and knowledge of NASA resources for enhancing student understanding and engagement in science. Moving into the fall, teachers will take part in a Community of Practice, where they will work to implement a place-based, data-rich moment in their individual classrooms. In the summer of 2025, teachers will take part in a second summer institute where they will continue to learn more about implementing place-based, data-rich instruction.

Via NASA Plane, Scientists Find New Gamma-ray Emission in Storm Clouds
Tropical thunderstorm with lightning, near the airport of Santa Marta, Colombia. Credit: Oscar van der Velde There’s more to thunderclouds than rain and lightning. Along with visible light emissions, thunderclouds can produce intense bursts of gamma rays, the most energetic form of light, that last for millionths of a second. The clouds can also glow steadily with gamma rays for seconds to minutes at a time.
Researchers using NASA airborne platforms have now found a new kind of gamma-ray emission that’s shorter in duration than the steady glows and longer than the microsecond bursts. They’re calling it a flickering gamma-ray flash. The discovery fills in a missing link in scientists’ understanding of thundercloud radiation and provides new insights into the mechanisms that produce lightning. The insights, in turn, could lead to more accurate lightning risk estimates for people, aircraft, and spacecraft.
Researchers from the University of Bergen in Norway led the study in collaboration with scientists from NASA’s Marshall Space Flight Center in Huntsville, Alabama, and NASA’s Goddard Space Flight Center in Greenbelt, Maryland, the U.S. Naval Research Laboratory, and multiple universities in the U.S., Mexico, Colombia, and Europe. The findings were described in a pair of papers in Nature, published Oct. 2.
The international research team made their discovery while flying a battery of detectors aboard a NASA ER-2 research aircraft. In July 2023, the ER-2 set out on a series of 10 flights from MacDill Air Force Base in Tampa, Florida. The plane flew figure-eight flight patterns a few miles above tropical thunderclouds in the Caribbean and Central America, providing unprecedented views of cloud activity.
The scientific payload was developed for the Airborne Lightning Observatory for Fly’s Eye Geostationary Lightning Mapper Simulator and Terrestrial Gamma-ray Flashes (ALOFT) campaign. Instrumentation in the payload included weather radars along with multiple sensors for measuring gamma rays, lightning flashes, and microwave emissions from clouds.

The flashes, first discovered in 1992 by NASA’s Compton Gamma Ray Observatory spacecraft, accompany some lightning strikes and last only millionths of a second. Despite their high intensity and their association with visible lightning, few TGFs have been spotted during previous aircraft-based studies.
“I went to a meeting just before the ALOFT campaign,” said principal investigator Nikolai Østgaard, a space physicist with the University of Bergen. “And they asked me: ‘How many TGFs are you going to see?’ I said: ‘Either we’ll see zero, or we’ll see a lot.’ And then we happened to see 130.”
However, the flickering gamma-ray flashes were a complete surprise.
“They’re almost impossible to detect from space,” said co-principal investigator Martino Marisaldi, who is also a University of Bergen space physicist. “But when you are flying at 20 kilometers [12.5 miles] high, you’re so close that you will see them.” The research team found more than 25 of these new flashes, each lasting between 50 to 200 milliseconds.
The abundance of fast bursts and the discovery of intermediate-duration flashes could be among the most important thundercloud discoveries in a decade or more, said University of New Hampshire physicist Joseph Dwyer, who was not involved in the research. “They’re telling us something about how thunderstorms work, which is really important because thunderstorms produce lightning that hurts and kills a lot of people.”
More broadly, Dwyer said he is excited about the prospects of advancing the field of meteorology. “I think everyone assumes that we figured out lightning a long time ago, but it’s an overlooked area … we don’t understand what’s going on inside those clouds right over our heads.” The discovery of flickering gamma-ray flashes may provide crucial clues scientists need to understand thundercloud dynamics, he said.
Turning to aircraft-based instrumentation rather than satellites ensured a lot of bang for research bucks, said the study’s project scientist, Timothy Lang of NASA’s Marshall Space Flight Center in Huntsville, Alabama.
“If we had gotten one flash, we would have been ecstatic — and we got well over 100,” he said. This research could lead to a significant advance in our understanding of thunderstorms and radiation from thunderstorms. “It shows that if you have the right problem and you’re willing to take a little bit of risk, you can have a huge payoff.”

Illustration of NASA’s BioSentinel spacecraft as it enters a heliocentric orbit. BioSentinel collected data during the May 2024 geomagnetic storm that hit Earth to learn more about the impacts of radiation in deep space.NASA/Daniel Rutter In May 2024, a geomagnetic storm hit Earth, sending auroras across the planet’s skies in a once-in-a-generation light display. These dazzling sights are possible because of the interaction of coronal mass ejections – explosions of plasma and magnetic field from the Sun – with Earth’s magnetic field, which protects us from the radiation the Sun spits out during turbulent storms.
But what might happen to humans beyond the safety of Earth’s protection? This question is essential as NASA plans to send humans to the Moon and on to Mars. During the May storm, the small spacecraft BioSentinel was collecting data to learn more about the impacts of radiation in deep space.
“We wanted to take advantage of the unique stage of the solar cycle we’re in – the solar maximum, when the Sun is at its most active – so that we can continue to monitor the space radiation environment,” said Sergio Santa Maria, principal investigator for BioSentinel’s spaceflight mission at NASA’s Ames Research Center in California’s Silicon Valley. “These data are relevant not just to the heliophysics community but also to understand the radiation environment for future crewed missions into deep space.”
BioSentinel – a small satellite about the size of a cereal box – is currently over 30 million miles from Earth, orbiting the Sun, where it weathered May’s coronal mass ejection without protection from a planetary magnetic field. Preliminary analysis of the data collected indicates that even though this was an extreme geomagnetic storm, that is, a storm that disturbs Earth’s magnetic field, it was considered just a moderate solar radiation storm, meaning it did not produce a great increase in hazardous solar particles. Therefore, such a storm did not pose any major issue to terrestrial lifeforms, even if they were unprotected as BioSentinel was. These measurements provide useful information for scientists trying to understand how solar radiation storms move through space and where their effects – and potential impacts on life beyond Earth – are most intense.
NASA’s Solar Dynamics Observatory captured this image of a solar flare on May 11, 2024. The image shows a subset of extreme ultraviolet light that highlights the extremely hot material in flares.NASA/SDO The original mission of BioSentinel was to study samples of yeast in deep space. Though these yeast samples are no longer alive, BioSentinel has adapted and continues to be a novel platform for studying the potential impacts of deep space conditions on life beyond the protection of Earth’s atmosphere and magnetosphere. The spacecraft’s biosensor instrument collects data about the radiation in deep space. Over a year and a half after its launch in Nov. 2022, BioSentinel retreats farther away from Earth, providing data of increasing value to scientists.
“Even though the biological part of the BioSentinel mission was completed a few months after launch, we believe that there is significant scientific value in continuing with the mission,” said Santa Maria. “The fact that the CubeSat continues to operate and that we can communicate with it, highlights the potential use of the spacecraft and many of its subsystems and components for future long-term missions beyond low Earth orbit.”
When we see auroras in the sky, they can serve as a stunning reminder of all the forces we cannot see that govern our cosmic neighborhood. As NASA and its partners seek to understand more about space environments, platforms like BioSentinel are essential to learn more about the risks of surviving beyond Earth’s sphere of protection.

NASA has awarded a contract extension to Stanford University, California, to continue the mission and services for the Helioseismic and Magnetic Imager (HMI) instrument on the agency’s Solar Dynamics Observatory (SDO).
The cost-reimbursement, no fee contract extension provides for support, operation, and calibration of the HMI instrument, which is one of three main instruments on SDO. In addition, the extension provides for operating and maintaining the Joint Science Operations Center – Science Data Processing facility at Stanford as well as the HMI team’s support for Heliophysics System Observatory science.
The period of performance for the extension runs Tuesday, Oct. 1, through Sept. 30, 2027. The extension increases the total contract value for HMI services by about $12.5 million — from $173.84 million to $186.34 million.
SDO’s mission is to help advance our understanding of the Sun’s influence on Earth and near-Earth space by studying how the star changes over time and how solar activity is created. Understanding the solar environment and how it drives space weather is vital to protecting ground and space-based infrastructure as well as NASA’s efforts to establish a sustainable presence on the Moon with Artemis. The study of the Sun also teaches us more about how stars contribute to the habitability of planets throughout the universe.
The SDO mission launched in February 2010 with science operations beginning in May of that year. The HMI instrument on SDO studies oscillations and the magnetic field at the solar surface, or photosphere.
