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.
The PLACES GMRI Summer Institute was made possible by a large co-design, collaborative effort across our partner organizations. This included:
Facilitation Team: Catherine Bursk (GMRI), Meggie Harvey (GMRI), Sara Salisbury (GMRI), Daniel Damelin (Concord Consortium) In-person Facilitation Support Team: Leigh Peake (GMRI), Karen Lionberger (WestEd), Kristin Hunter-Thomson (Dataspire), Angela Rizzi (NASA Langley) In-Person Team Member Participants: Janet Struble and Kevin Czaikowski (GLOBE, University of Toledo), Svetlana Darche (WestEd) Virtual Observers: Kirsten Daehler, Nicole Wong, Leticia Perez (WestEd), Tracy Ostrom (GLOBE, UC Berkeley), Lori Rubino-Hare (NAU) Additional support: Frieda Reichsman (Concord Consortium), Barbie Buckner and Jessia Taylor (NASA Langley), Sean Ryan (NAU), Lauren Shollenberger (NAU) PLACES is supported by NASA under cooperative agreement award number 80NSSC22M0005 and is part of NASA’s Science Activation Portfolio.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA MSFC HERC is the annual engineering competition – one of NASA’s longest standing challenges – held its concluding event April 19 and April 20, at the U.S. Space & Rocket Center in Huntsville, near NASA’s Marshall Space Flight Center.NASA NASA has selected 75 student teams to begin an engineering design challenge to build rovers that will compete next spring at the U.S. Space and Rocket Center near the agency’s Marshall Space Flight Center in Huntsville, Alabama. The competition is one of the agency’s Artemis Student Challenges, encouraging students to pursue degrees and careers in science, technology, engineering, and mathematics (STEM).
Recognized as NASA’s leading international student challenge, the 31st annual Human Exploration Rover Challenge (HERC) aims to put competitors in the mindset of NASA’s Artemis campaign as they pitch an engineering design for a lunar terrain vehicle which simulates astronauts piloting a vehicle, exploring the lunar surface while overcoming various obstacles.
Participating teams represent 35 colleges and universities, 38 high schools, and two middle schools from 20 states, Puerto Rico, and 16 other nations from around the world. The 31st annual Human Exploration Rover Challenge (HERC) is scheduled to begin on April 11, 2025. The challenge is managed by NASA’s Southeast Regional Office of STEM Engagement at NASA Marshall.
Following a 2024 competition that garnered international attention, NASA expanded the challenge to include a remote-control division, Remote-Operated Vehicular Research, and invited middle school students to participate. The 2025 HERC Handbook includes guidelines for the new remote-control division and updates for the human-powered division.
NASA’s Artemis Student Challenges reflects the goals of the Artemis campaign, which seeks to land the first woman and first person of color on the Moon while establishing a long-term presence for science and exploration.
More than 1,000 students with 72 teams from around the world participated in the 2024 challenge as HERC celebrated its 30th anniversary as a NASA competition. Since its inception in 1994, more than 15,000 students have participated in HERC – with many former students now working at NASA, or within the aerospace industry.

On Sept. 9 and 10, scientists and engineers tested NASA’s LEMS (Lunar Environment Monitoring Station) instrument suite in a “sandbox” of simulated Moon regolith at the Florida Space Institute’s Exolith Lab at the University of Central Florida in Orlando.
Lunar regolith is a dusty, soil-like material that coats the Moon’s surface, and researchers wanted to observe how the material would interact with LEMS’s hardware, which is being developed to fly to the Moon with Artemis III astronauts in late 2026.
Designed and built at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, LEMS is one of three science payloads chosen for development for Artemis III, which will be the first mission to land astronauts on the lunar surface since 1972.
The LEMS instrument package can operate both day and night. It will carry two University of Arizona-built seismometers to the surface to perform long-term monitoring for moonquakes and meteorite impacts.

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.

Figure 1. An artist’s concept of the Van Allen belts with a cutaway section of the giant donuts of radiation that surround Earth. Image Credit: NASA Goddard Space Flight Center/Scientific Visualization Studio A new instrument is using advanced detection techniques and leveraging an orbit with specific characteristics to increase our understanding of the Van Allen belts—regions surrounding Earth that contain energetic particles that can endanger both robotic and human space missions. Recently, the instrument provided a unique view of changes to this region that were brought on by an intense magnetic storm in May 2024.
The discovery of the Van Allen radiation belts by the U.S. Explorer 1 mission in 1958 marked a prominent milestone in space physics and demonstrated that Earth’s magnetosphere efficiently accelerates and traps energetic particles. The inner belt contains protons in the MeV (million electric volt) to GeV (109 electric volt) range, and even higher concentrations of energetic electrons of 100s of keV (1000 electric volt) to MeV are found in both the inner belt and the outer belt.
The energetic electrons in these belts—also referred to as “killer electrons”—can have detrimental effects on spacecraft subsystems and are harmful to astronauts performing extravehicular activities. Understanding the source, loss, and varying concentrations of these electrons has been a longstanding research objective. High-energy resolution and clean measurements of these energetic electrons in space are required to further our understanding of their properties and enable more reliable prediction of their intensity.
Overcoming the challenges of measuring relativistic electrons in the inner belt
Measuring energetic electrons cleanly and accurately has been a challenge, especially in the inner belt, where MeV to GeV energy protons also exist. NASA’s Van Allen Probes, which operated from 2012 to 2019 in low inclination, geo-transfer-like orbits, showed that instruments traversing the heart of the inner radiation belt are subject to penetration by the highly energetic protons located in that region. The Relativistic Electron Proton Telescope (REPT) and the Magnetic Electron and Ion Spectrometer (MagEIS) instruments onboard the Van Allen Probes were heavily shielded but were still subject to inner-belt proton contamination.
To attempt to minimize these negative effects, a University of Colorado Boulder team led by Dr. Xinlin Li, designed the Relativistic Electron Proton Telescope integrated little experiment (REPTile)—a simplified and miniaturized version of REPT—to fly onboard the Colorado Student Space Weather Experiment (CSSWE). An effort supported by the National Science Foundation, the 3-Unit CSSWE CubeSat operated in a highly inclined low Earth orbit (LEO) from 2012 to 2014. In this highly inclined orbit, the spacecraft and the instruments it carried were only exposed to the inner-belt protons in the South Atlantic Anomaly (SAA) region where the Earth’s magnetic field is weaker, which greatly reduced the time that protons impacted the measurement of electrons.
REPTile’s success motivated a team, also led by Dr. Xinlin Li, to design REPTile-2—an advanced version of REPTile—to be hosted on the Colorado Inner Radiation Belt Experiment (CIRBE) mission. Like CSSWE, CIRBE operates in a highly inclined low-Earth orbit to ensure the exposure to damaging inner-belt protons is minimized. The team based the REPTile-2 design on REPTile but incorporated two additional technologies—guard rings and Pulse Height Analysis—to enable clean, high-energy-resolution measurements of energetic electrons, especially in the inner belt.
Figure 2: PI observing two engineers testing the interface between the CIRBE bus and REPTile-2 on September 29, 2021. Image Credit: Xinlin Li, University of Colorado Boulder As shown on the left in Figure 3, the field of view (FOV) of REPTile-2 is 51o. Electrons and protons enter the FOV and are measured when they reach a stack of silicon detectors where they deposit their energies. However, very energetic protons (energy greater than 60 MeV) could penetrate through the instrument’s tungsten and aluminum shielding and masquerade as valid particles, thus contaminating the intended measurements. To mitigate this contamination, the team designed guard rings that surround each detector. These guard rings are electronically separated from the inner active area of each detector and are connected by a separate electric channel. When the guard rings are triggered (i.e., hit by particles coming outside of the FOV), the coincident measurements are considered invalid and are discarded. This anti-coincidence technique enables cleaner measurements of particles coming through the FOV.
Figure 3. Left (adapted from Figure 1 of Khoo et al., 2022): Illustration of REPTile-2 front end with key features labeled; Right: REPTile-2 front end integrated with electronic boards and structures, a computer-aided design (CAD) model, and a photo of integrated REPTile-2. Image Credit: Xinlin Li, University of Colorado Boulder To achieve high energy resolution, the team also applied full Pulse Height Analysis (PHA) on REPTile-2. In PHA, the magnitude of measured charge in the detector is directly proportional to the energy deposited from the incident electrons. Unlike REPTile, which employed a simpler energy threshold discrimination method yielding three channels for the electrons, REPTile-2 offers enhanced precision with 60 energy channels for electron energies ranging from 0.25 – 6 MeV. The REPT instrument onboard the Van Allen Probes also employed PHA but while REPT worked very well in the outer belt, yielding fine energy resolution, it did not function as well in the inner belt since the instrument was fully exposed to penetrating energetic protons because it did not have the guard rings implemented.
Figure 4: The CIRBE team after a successful “plugs-out” test of the CIRBE spacecraft on July 21, 2022. During this test the CIRBE spacecraft successfully received commands from ground stations and completed various performance tests, including data transmission back to ground stations at LASP. Image Credit: Xinlin Li, University of Colorado Boulder CIRBE and REPTile-2 Results
CIRBE’s launch, secured through the NASA CubeSat Launch Initiative (CSLI), took place aboard SpaceX’s Falcon 9 rocket as part of the Transporter-7 mission on April 15, 2023. REPTile-2, activated on April 19, 2023, has been performing well, delivering valuable data about Earth’s radiation belt electrons. Many features of the energetic electrons in the Van Allen belts have been revealed for the first time, thanks to the high-resolution energy and time measurements REPTile-2 has provided.
Figure 5 shows a sample of CIRBE/REPTile-2 measurements from April 2024, and illustrates the intricate drift echoes or “zebra stripes” of energetic electrons, swirling around Earth in distinct bunches. These observations span a vast range across the inner and outer belts, encompassing a wide spectrum of energies and electron fluxes extending over six orders of magnitude. By leveraging advanced guard rings, Pulse Height Analysis (PHA), and a highly inclined LEO orbit, REPTile-2 is delivering unprecedented observations of radiation belt electrons.
Figure 5: Color-coded electron fluxes detrended between REPTile-2 measurements for a pass over the South Atlantic Anomaly region on April 24, 2023, and their average, i.e., the smoothed electron fluxes using a moving average window of ±19% in energy; Black curves plotted on top of the color-coded electron fluxes are contours of electron drift period in hr. The second horizontal-axis, L, represents the magnetic field line, which CIRBE crosses. The two radiation belts and a slot region in between are indicated by the red lines and arrow, respectively. Image Credit: Xinlin Li, University of Colorado Boulder In fact, the team recently announced that measurements from CIRBE/REPTile-2 have revealed a new temporary third radiation belt composed of electrons and sandwiched between the two permanent belts. This belt formed during the magnetic storm in May 2024, which was the largest in two decades. While such temporary belts have been seen after big storms previously, the data from CIRBE/REPTile-2 are providing a new viewpoint with higher energy resolution data than before. Scientists are currently studying the data to better understand the belt and how long it might stick around — which could be many months.
