      NASA Selects Winners of the 2024-2025 Power to Explore Challenge
      Ten-year-old, Terry Xu of Arcadia, California; 14-year-old, Maggie Hou of Snohomish, Washington; and 17-year-old, Kairat Otorov of Trumbull, Connecticut, winners of the 2024-2025 Power to Explore Student Writing Challenge. NASA/David Lam, Binbin Zheng, The Herald/Olivia Vanni, Meerim Otorova NASA has chosen three winners out of nine finalists in the fourth annual Power to Explore Challenge, a national writing competition designed to teach K-12 students about the enabling power of radioisotopes for space exploration.
      “Congratulations to the amazing champions and all of the participants!
      Carl Sandifer II
      Program Manager, NASA’s Radioisotope Power Systems Program
      The essay competition asked students to learn about NASA’s radioisotope power systems (RPS), likened to “nuclear batteries,” which the agency has used discover “moonquakes” on Earth’s Moon and study some of the most extreme of the more than 891 moons in the solar system. In 275 words or less, students dreamed up a unique exploration mission of one of these moons and described their own power to achieve their mission goals.
      “I’m so impressed by the creativity and knowledge of our Power to Explore winners,” said Carl Sandifer II, program manager of the Radioisotope Power Systems Program at NASA’s Glenn Research Center in Cleveland.
      Entries were split into three groups based on grade level, and a winner was chosen from each. The three winners, each accompanied by a guardian, are invited to NASA’s Glenn Research Center in Cleveland for a VIP tour of its world-class research facilities this summer.
      The winners are:
      Terry Xu, Arcadia, California, kindergarten through fourth grade Maggie Hou, Snohomish, Washington, fifth through eighth grade Kairat Otorov, Trumbull, Connecticut, ninth through 12th grade “Congratulations to the amazing champions and all of the participants! Your “super powers” inspire me and make me even more optimistic about the future of America’s leadership in space,” Sandifer said.
      The Power to Explore Challenge offered students the opportunity to learn about space power, celebrate their own strengths, and interact with NASA’s diverse workforce. This year’s contest received nearly 2,051 submitted entries from all 50 states, U.S. territories, and the Department of Defense Education Activity overseas.
      Every student who submitted an entry received a digital certificate and an invitation to the Power Up virtual event held on March 21. There, NASA announced the 45 national semifinalists, and students learned about what powers the NASA workforce.
      Additionally, the national semifinalists received a NASA RPS prize pack.
      NASA announced three finalists in each age group (nine total) on April 23. Finalists were invited to discuss their mission concepts with a NASA scientist or engineer during an exclusive virtual event.
      The challenge is funded by the Radioisotope Power Systems Program Office in NASA’s Science Mission Directorate and administered by Future Engineers under a Small Business Innovation Research phase III contract. This task is managed by the NASA Tournament Lab, a part of the Prizes, Challenges, and Crowdsourcing Program in NASA’s Space Technology Mission Directorate.

      NASA Data Helps Map Tiny Plankton That Feed Giant Right Whales
      This North Atlantic right whale, named “Bowtie,” was spotted feeding in southern Maine waters in January 2025. A new technique aims to use NASA satellite data to see the plankton these whales depend on from space. Credit: New England Aquarium, taken under NMFS permit # 25739 In the waters off New England, one of Earth’s rarest mammals swims slowly, mouth agape. The North Atlantic right whale filters clouds of tiny reddish zooplankton — called Calanus finmarchicus — from the sea. These zooplankton, no bigger than grains of rice, are the whale’s lifeline. Only about 370 of these massive creatures remain.
      For decades, tracking the tiny plankton meant sending research vessels out in the ocean, towing nets and counting samples by hand. Now, scientists are looking from above instead.
      Using NASA satellite data, researchers found a way to detect Calanus swarms at the ocean surface in the Gulf of Maine, picking up on the animals’ natural red pigment. This early-stage approach, described in a new study, may help researchers better estimate where the copepods gather, and where whales might follow.
      Tracking the zooplankton from space could aid both the whales and maritime industries. By predicting where these mammals are likely to feed, researchers and marine resource managers hope to reduce deadly vessel strikes and fishing gear entanglements — two major threats to the species. Knowing the feeding patterns could also help shipping and fishing industries operate more efficiently.
      Calanus finmarchicus, a tiny zooplankton powering North Atlantic food webs, fuels right whale populations with its energy-rich lipid reserves. Credit: Cameron Thompson “NASA invests in this kind of research because it connects space-based observation with real-world challenges,” said Cynthia Hall, a support scientist at NASA headquarters in Washington. She works with the Early Career Research Program, which partly funded the work. “It’s yet another a way to put NASA satellite data to work for science, communities, and ecosystems.”
      Revealing the Ocean’s Hidden Patterns
      The new approach uses data from the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard NASA’s Aqua satellite. The MODIS instrument doesn’t directly see the copepods themselves. Instead, it reads how the spectrum of sunlight reflected from the ocean surface changes in response to what’s in the water.
      When large numbers of the zooplankton rise to the surface, their reddish pigment — astaxanthin, the same compound that gives salmon its pink color — subtly alters how photons, or particles of light, from the sun are absorbed or scattered in the water. The fate of these photons in the ocean depends on the mix of living and non-living matter in seawater, creating a slight shift in color that MODIS can detect.
      “We didn’t know to look for Calanus before in this way,” said Catherine Mitchell, a satellite oceanographer at Bigelow Laboratory for Ocean Sciences in East Boothbay, Maine. “Remote sensing has typically focused on smaller things like phytoplankton. But recent research suggested that larger, millimeter-sized organisms like zooplankton can also influence ocean color.”
      A few years ago, researchers piloted a satellite method for detecting copepods in Norwegian waters. Now, some of those same scientists — along with Mitchell’s team — have refined the approach and applied it to the Gulf of Maine, a crucial feeding ground for right whales during their northern migration. By combining satellite data, a model, and field measurements, they produced enhanced images that revealed Calanus swarms at the sea surface, and were able to estimate numbers of the tiny animals.
      “We know the right whales are using habitats we don’t fully understand,” said Rebekah Shunmugapandi, also a satellite oceanographer at Bigelow and the study’s lead author. “This satellite-based Calanus information could eventually help identify unknown feeding grounds or better anticipate where whales might travel.”
      Tracking Elusive Giants
      Despite decades of study, North Atlantic right whales remain remarkably enigmatic to scientists. Once fairly predictable in their movements along the Eastern Seaboard of North America, these massive mammals began abandoning some traditional feeding grounds in 2010-2011. Their sudden shift to unexpected areas like the Gulf of Saint Lawrence caught people off guard, with deadly consequences.
      “We’ve had whales getting hit by ships and whales getting stuck in fishing gear,” said Laura Ganley, a research scientist in the Anderson Cabot Center for Ocean Life at the New England Aquarium in Boston, which conducts aerial and boat surveys of the whales.  
      In 2017, the National Oceanic and Atmospheric Administration designated the situation as an “unusual mortality event” in an effort to address the whales’ decline. Since then, 80 North Atlantic right whales have been killed or sustained serious injuries, according to NOAA.
      NASA satellite imagery from June 2009 was used to test a new method for detecting the copepod Calanus finmarchicus in the Gulf of Maine and estimating their numbers from space. Credit: NASA Earth Observatory image by Wanmei Liang, using data from Shunmugapandi, R., et al. (2025) In the Gulf of Maine, there’s less shipping activity, but there can be a complex patchwork of lobster fishing gear, said Sarah Leiter, a scientist with the Maine Department of Marine Resources. “Each fisherman has 800 traps or so,” Leiter explained. “If a larger number of whales shows up suddenly, like they just did in January 2025, it is challenging. Fishermen need time and good weather to adjust that gear.”
      What excites Leiter the most about the satellite data is the potential to use it in a forecasting tool to help predict where the whales could go. “That would be incredibly useful in giving us that crucial lead time,” she said.
      PACE: The Next Generation of Ocean Observer
      For now, the Calanus-tracking method has limitations. Because MODIS detects the copepods’ red pigment, not the animals themselves, that means other small, reddish organisms can be mistaken for the zooplankton. And cloud cover, rough seas, or deeper swarms all limit what satellites can spot.
      MODIS is also nearing the end of its operational life. But NASA’s next-generation PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) satellite — launched in 2024 — is poised to make dramatic improvements in the detection of zooplankton and phytoplankton.
      NASA’s Ocean Color Instrument on the PACE satellite captured these swirling green phytoplankton blooms in the Gulf of Maine in April 2024. Such blooms fuel zooplankton like Calanus finmarchicus. Credit: NASA “The PACE satellite will definitely be able to do this, and maybe even something better,” said Bridget Seegers, an oceanographer and mission scientist with the PACE team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland.
      The PACE mission includes the Ocean Color Instrument, which detects more than 280 wavelengths of light. That’s a big jump from the 10 wavelengths seen by MODIS. More wavelengths mean finer detail and better insights into ocean color and the type of plankton that the satellite can spot.
      Local knowledge of seasonal plankton patterns will still be essential to interpret the data correctly. But the goal isn’t perfect detection, the scientists say, but rather to provide another tool to inform decision-making, especially when time or resources are limited.

      NASA Langley highlights its Cirrus Design SR22 during Air Power Over Hampton Roads STEM Day. NASA/Angelique Herring NASA Langley Research Center’s integral role in the past, present, and future of flight was on full display April 25-27 during the Air Power Over Hampton Roads air show.
      The air show, held at Joint Base Langley-Eustis (JBLE), which neighbors NASA Langley in Hampton, Virginia, attracted thousands of spectators throughout the weekend.
      The weekend kicked off with a STEM Day on April 25. Langley’s Office of STEM Engagement (OSTEM) offered educational and engaging activities, exhibits, and displays to share NASA missions and encourage K-12 students from local schools to explore the possibilities that science, technology, engineering, and math offer.
      “Participation in the air show allows us to share NASA’s work in aeronautics with the public and provides an opportunity for Langley researchers and engineers to work directly with students and families to share the exciting work they do,” said Bonnie Murray, Langley OSTEM Student Services manager.
      NASA Langley personnel inspire young minds during Air Power Over Hampton Roads STEM Day.NASA/Angelique Herring Langley OSTEM’s participation continued throughout the weekend as a part of the air show’s STEM Expo, where visitors to the NASA booths tested a paper helicopter in a small-scale wind tunnel to explore flight dynamics, learned how NASA uses X-planes for research and designed their own X-plane, and tested experimental paper airplanes of various designs. By observing flight of the plane designs and making improvements to each one, students participated in the engineering design process. NASA subject matter experts in attendance guided students through these activities, inspired young minds by sharing some of their innovations, and promoted a variety of STEM career paths.
      “Through engagement in the NASA STEM Zone activities, students had an opportunity to see themselves in the role of a NASA researcher,” Murray said. “Authentic learning experiences such as these help build children’s STEM identity, increasing the likelihood of them pursuing STEM careers in the future.”

      “Reflective of our strong, long-standing partnership with JBLE, NASA Langley was proud to participate in this year’s Air Power Over Hampton Roads air show,” said Glenn Jamison, director of Langley’s Research Services Directorate. “Our relationship spans back to 1917 when NACA and Langley Field evolved together over formative years in aerodynamic research, sharing the airspace and facilities here in Hampton. Today, we continue our collaboration with JBLE in pursuing shared interests and finding innovative solutions to complex problems.”
      The displays also featured several small Unmanned Aircraft Systems (sUAS) and NASA’s P-3 Orion, a research aircraft based at NASA’s Wallops Flight Facility on Wallops Island, Virginia.
      Air show visitors could explore a picture display that highlighted NASA Langley’s rich aviation legacy, from its founding in 1917 to Langley’s work today to accelerate advancements in aeronautics, science, and space technology and exploration. Spacey Casey, a crowd favorite, greeted and took pictures with educators, students, and guests throughout the weekend, bringing out-of-this-world smiles to their faces. Members of Langley’s Office of the Director also represented the center at the event.

      The competition asked students to learn about NASA’s radioisotope power systems (RPS), likened to a “nuclear battery” that the agency uses to explore some of the most extreme destinations in our solar system and beyond. Long before the early days of Apollo, our Moon has inspired explorers of all ages to push beyond known limits to realize impossible dreams. These systems have enabled NASA to discover “moonquakes” on Earth’s Moon and study some of the most extreme moons of the solar system, which have active volcanoes, methane lakes, and ice glaciers. As of March 25, NASA has discovered over 891 moons, each with secrets ready to be unlocked.
      Students were challenged to pick any moon in our solar system’s exploration could be enabled by this space power systems. In 275 words or less, they dreamed up a unique exploration mission of this moon and described their own power to achieve their mission goals.
      The Power to Explore Challenge offered students the opportunity to learn more about these reliable power systems, celebrate their own strengths, and interact with NASA’s diverse workforce. This year’s contest received 2,051 submitted entries from all 50 states, U.S. territories, and the Department of Defense Education Activity overseas.
      “I am always so impressed by quality of the essays and the creativity of the ideas that the students submit to NASA’s Power to Explore Challenge.” said Carl Sandifer, program manager of the Radioisotope Power Systems Program at NASA’s Glenn Research Center in Cleveland. “I’m looking forward to welcoming the winners to NASA’s Glenn this summer.”
