GLOBE, NASA, and the Monsignor McClancy Memorial High School in Queens, New York
When students actively participate in scientific investigations that connect to their everyday lives, something powerful happens: they begin to see themselves as scientists. This sense of relevance and ownership can spark a lifelong interest in science, technology, engineering, and math (STEM), paving the way for continued education and even future careers in these fields. Opportunities to engage directly with NASA science—like the one you’ll read about in this story—not only deepen students’ understanding of STEM concepts, but also nourish their curiosity and confidence. With the support of passionate educators, these moments of participation become stepping stones to a future in which students see themselves as contributors to real-world science.
In September 2021, Ms. Deanna Danke, a Monsignor McClancy Memorial High School mathematics teacher in Queens, New York, began teaching her students how to measure tree heights using trigonometry. Soon enough, Ms. Danke discovered the Global Learning and Observations to Benefit the Environment (GLOBE) Observer Trees Tool, and with her 150+ students, began taking tree height observations around the school, an activity that Ms. Danke and her students continue to participate in today. Her and her students’ hundreds of repeat tree height observations have provided student and professional researchers with clusters of measurements that can coincide with measurements made by NASA satellite instruments, allowing for a comparison of datasets that can be analyzed over time.
Due to the consistent tree height data collection resulting from this effort, Ms. Danke was asked to be a co-author on a peer-reviewed research paper that was published on June 21, 2022 in the Environmental Research Letters special journal “Focus on Public Participation in Environmental Research.” The paper, “The potential of citizen science data to complement satellite and airborne lidar tree height measurements: lessons from The GLOBE Program,” included data from the tree height observations reported by Ms. Danke and her students—an incredible achievement for everyone involved.
On March 21, 2025, Ms. Danke’s former and current students continued their inspiring adventures with NASA science by taking a trip to the NASA Wallops Flight Facility in Wallops Island, Virginia. Highlights from this trip included science and technology presentations by personnel from the Ice, Cloud, and land Elevation Satellite-2 (ICESat-2) and Global Precipitation Measurement (GPM) Missions, the Wallops Balloon Program Office, and the Wallops Machine Shop for Fabrication and Testing. The ICESat-2 presentation, in particular, included a discussion on the student-collected tree height data and how the ICESat-2 satellite makes tree height observations from space.
Ms. Danke’s work is a testament to the incredible impact educators can have when they connect classroom learning to authentic scientific discovery. By introducing her students to tools like the GLOBE Observer Trees Tool and facilitating meaningful contributions to NASA science, she opened the door to experiences most students only dream of—from collecting data that supports satellite missions to co-authoring peer-reviewed research and visiting NASA facilities. Stories like this remind us that when students are empowered to be part of real science, the possibilities—for learning, inspiration, and future careers in STEM—are truly limitless.
The GLOBE Observer app, used by Ms. Danke and her students, is made possible by the NASA Earth Science Education Collaborative (NESEC). This free mobile app includes four tools that enable citizen scientists to participate in NASA science: Clouds, Mosquito Habitat Mapper, Land Cover, and Trees. Learn more about ways that you can join and participate in this and other NASA Citizen Science projects. Through these projects, sometimes called “participatory science” projects, volunteers and amateurs have helped make thousands of important scientific discoveries, and they are open to everyone around the world (no citizenship required).
NESEC is supported by NASA under cooperative agreement award number NNX16AE28A and is part of NASA’s Science Activation Portfolio.

Map of tree height around the Monsignor McClancy Memorial High School from the GLOBE Program’s Visualization System. I know this was an experience they will remember forever and they have already told me that they cannot wait to tell their future children about it. It was wonderful meeting you in person and being on site to get a real sense of what you are working on. The boys were especially fascinated by the last two stops on the tour and appreciated learning a little more about how tree height is measured. Thank you again for this incredible opportunity.”

The airborne Lunar Spectral Irradiance (air-LUSI) instrument is moved across the hangar floor by robotic engineer Alexander McCafferty-Leroux ,from right to left, co-investigator Dr. John Woodward, NIST astronomer Dr. Susana Deustua, air-LUSI chief system engineer Dr. Kathleen “Kat” Scanlon, and members of the ER-2 ground crew at NASA’s Armstrong Flight Research Center in Edwards, California, in March 2025.NASA/Genaro Vavuris Flying high above the clouds and moon-gazing may sound like a scene from a timeless romance, but NASA did just that in the name of Earth science research. In March 2025 pilots took the agency’s ER-2 science aircraft on a series of night flights over NASA’s Armstrong Flight Research Center in Edwards, California, as the Moon increased in visible size. For those few nights, the high-flying plane was converted into a one-of-a-kind airborne lunar observatory.
The Airborne Lunar Spectral Irradiance, or air-LUSI, mission observed the Moon at different phases and measured the sunlight reflected by the lunar surface. Specifically, the instrument tracks the amount of light reflected at different wavelengths. This information enables scientists to use the Moon as a calibration tool for Earth-observing sensors.
As an “absolute reference, the Moon also becomes the perfect benchmark for satellites to consistently and accurately measure processes on Earth,” said Kevin Turpie, air-LUSI’s principal investigator and a researcher based at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. This helps scientists to improve the precision of many different measurements, including data on weather patterns, vegetation growth, and ocean conditions.
As the highest-flying platform for airborne science, the ER-2 can fly the air-LUSI instrument in the stratosphere, above 95% of the atmosphere. Data collected at an altitude nearing 70,000 feet are highly accurate because the air is predominantly clear of the gases and particles found in the lower atmosphere that can interfere with measurements.
The ER-2 aircraft is parked in a hangar at NASA’s Armstrong Flight Research Center in Edwards, California, in March 2025. The plane is prepared for takeoff to support the airborne Lunar Spectral Irradiance, or air-LUSI, mission.NASA/Genaro Vavuris “To date, air-LUSI measurements of the Moon are the most accurate ever made,” said Kelsey Bisson, the NASA program scientist supporting the mission. “Air-LUSI data can advance our ability to understand the Earth and our weather, and they provide a new way to calibrate satellites that can result in cost savings.”
The quality of these data has transformative implications for satellite and Earth observing systems. The improved accuracy and enhanced ability provided by air-LUSI data flown on the ER-2 reduces the need for onboard reference devices, effectually cutting satellite costs.
The air-LUSI project is a collaboration between scientists and engineers from NASA, the National Institute of Standards and Technology, the U.S. Geological Survey, the University of Maryland Baltimore County, and McMaster University in Ontario.
The ER-2 ground crew Wissam Habbal, left, and Dr. Kevin Turpie, airborne Lunar Spectral Irradiance (air-LUSI) principal investigator, guide delicate fiber optic and electric cabling into place while uploading the air-LUSI instrument onto the ER-2 aircraft in March 2025 at NASA’s Armstrong Flight Research Center in Edwards, California.NASA/Genaro Vavuris “The collective effort of the American and Canadian team members offers an opportunity for truly exciting engineering and science collaboration,” said Andrew Gadsden, associate professor and associate chair for graduate studies in mechanical engineering at McMaster University, and co-investigator on the air-LUSI project. The McMaster team developed the Autonomous Robotic Telescope Mount Instrument System and High-Altitude Aircraft Mounted Robotic (HAAMR) telescope mount, which support the air-LUSI system.
Dr. John Woodward, of the National Institute of Standards and Technology and co-investigator on the airborne Lunar Spectral Irradiance (air-LUSI) mission, prepares the instrument for upload onto the ER-2 aircraft in March 2025 at NASA’s Armstrong Flight Research Center in Edwards, California.NASA/Genaro Vavuris The HAAMR telescope mount was integrated onto the ER-2 and flown for the first time during the science flights in March. This new lunar tracking system is contributing to what John Woodward IV, co-investigator for air-LUSI, called the “highest accuracy measurements” of moonlight. To improve Earth observation technology, air-LUSI represents an important evolutionary step.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Have we ever been to Uranus?
The answer is simple, yes, but only once. The Voyager II spacecraft flew by the planet Uranus back in 1986, during a golden era when the Voyager spacecraft explored all four giant planets of our solar system. It revealed an extreme world, a planet that had been bowled over onto its side by some extreme cataclysm early in the formation of the solar system.
That means that its seasons and its magnetic field get exposed to the most dramatic seasonal variability of any place that we know of in the solar system. The atmosphere was a churning system made of methane and hydrogen and water, with methane clouds showing up as white against the bluer background of the planet itself.
The densely packed ring system is host to a number of very fine, narrow and dusty rings surrounded by a collection of icy satellites. And those satellites may harbor deep, dark, hidden oceans beneath an icy crust of water ice.
Taken together, this extreme and exciting system is somewhere that we simply must go back to explore and hopefully in the next one to two decades NASA and the European Space Agency will mount an ambitious mission to go out there and explore the Uranian system. It’s important not just for solar system science, but also for the growing field of exoplanet science. As planets of this particular size, the size of Uranus, about four times wider than planet Earth, seem to be commonplace throughout our galaxy.
So how have we been to Uranus? Yes, but it’s time that we went back.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
This mosaic showing the Martian surface outside of Jezero Crater was taken by NASA’s Perseverance on Dec. 25, 2024, at the site where the rover cored a sample dubbed “Silver Mountain” from a rock likely formed during Mars’ earliest geologic period.NASA/JPL-Caltech/ASU/MSSS The diversity of rock types along the rim of Jezero Crater offers a wide glimpse of Martian history.
Scientists with NASA’s Perseverance rover are exploring what they consider a veritable Martian cornucopia full of intriguing rocky outcrops on the rim of Jezero Crater. Studying rocks, boulders, and outcrops helps scientists understand the planet’s history, evolution, and potential for past or present habitability. Since January, the rover has cored five rocks on the rim, sealing samples from three of them in sample tubes. It’s also performed up-close analysis of seven rocks and analyzed another 83 from afar by zapping them with a laser. This is the mission’s fastest science-collection tempo since the rover landed on the Red Planet more than four years ago.
Perseverance climbed the western wall of Jezero Crater for 3½ months, reaching the rim on Dec. 12, 2024, and is currently exploring a roughly 445-foot-tall (135-meter-tall) slope the science team calls “Witch Hazel Hill.” The diversity of rocks they have found there has gone beyond their expectations.
“During previous science campaigns in Jezero, it could take several months to find a rock that was significantly different from the last rock we sampled and scientifically unique enough for sampling,” said Perseverance’s project scientist, Katie Stack Morgan of NASA’s Jet Propulsion Laboratory in Southern California. “But up here on the crater rim, there are new and intriguing rocks everywhere the rover turns. It has been all we had hoped for and more.”
One of Perseverance’s hazard cameras captured the rover’s coring drill collecting the “Main River” rock sample on “Witch Hazel Hill” on March 10, 2025, the 1,441st Martian day, or sol, of the mission. NASA/JPL-Caltech That’s because Jezero Crater’s western rim contains tons of fragmented once-molten rocks that were knocked out of their subterranean home billions of years ago by one or more meteor impacts, including possibly the one that produced Jezero Crater. Perseverance is finding these formerly underground boulders juxtaposed with well-preserved layered rocks that were “born” billions of years ago on what would become the crater’s rim. And just a short drive away is a boulder showing signs that it was modified by water nestled beside one that saw little water in its past.
Oldest Sample Yet?
Perseverance collected its first crater-rim rock sample, named “Silver Mountain,” on Jan. 28. (NASA scientists informally nickname Martian features, including rocks and, separately, rock samples, to help keep track of them.) The rock it came from, called “Shallow Bay,” most likely formed at least 3.9 billion years ago during Mars’ earliest geologic period, the Noachian, and it may have been broken up and recrystallized during an ancient meteor impact.
About 360 feet (110 meters) away from that sampling site is an outcrop that caught the science team’s eye because it contains igneous minerals crystallized from magma deep in the Martian crust. (Igneous rocks can form deep underground from magma or from volcanic activity at the surface, and they are excellent record-keepers — particularly because mineral crystals within them preserve details about the precise moment they formed.) But after two coring attempts (on Feb. 4 and Feb. 8) fizzled due to the rock being so crumbly, the rover drove about 520 feet (160 meters) northwest to another scientifically intriguing rock, dubbed “Tablelands.”
Data from the rover’s instruments indicates that Tablelands is made almost entirely of serpentine minerals, which form when large amounts of water react with iron- and magnesium-bearing minerals in igneous rock. During this process, called serpentinization, the rock’s original structure and mineralogy change, often causing it to expand and fracture. Byproducts of the process sometimes include hydrogen gas, which can lead to the generation of methane in the presence of carbon dioxide. On Earth, such rocks can support microbial communities.
Coring Tablelands went smoothly. But sealing it became an engineering challenge.
Sealing the “Green Gardens” sample — collected by NASA’s Perseverance Mars rover from a rock dubbed “Tablelands” along the rim of Jezero Crater on Feb. 16, 2025 — pre-sented an engineering challenge. The sample was finally sealed on March 2.NASA/JPL-Caltech/ASU/MSSS Flick Maneuver
“This happened once before, when there was enough powdered rock at the top of the tube that it interfered with getting a perfect seal,” said Kyle Kaplan, a robotics engineer at JPL. “For Tablelands, we pulled out all the stops. Over 13 sols,” or Martian days, “we used a tool to brush out the top of the tube 33 times and made eight sealing attempts. We even flicked it a second time.”
During a flick maneuver, the sample handling arm — a little robotic arm in the rover’s belly — presses the tube against a wall inside the rover, then pulls the tube away, causing it to vibrate. On March 2, the combination of flicks and brushings cleaned the tube’s top opening enough for Perseverance to seal and store the serpentine-laden rock sample.
Eight days later, the rover had no issues sealing its third rim sample, from a rock called “Main River.” The alternating bright and dark bands on the rock were like nothing the science team had seen before.
Up Next
Following the collection of the Main River sample, the rover has continued exploring Witch Hazel Hill, analyzing three more rocky outcrops (“Sally’s Cove,” “Dennis Pond,” and “Mount Pearl”). And the team isn’t done yet.
“The last four months have been a whirlwind for the science team, and we still feel that Witch Hazel Hill has more to tell us,” said Stack. “We’ll use all the rover data gathered recently to decide if and where to collect the next sample from the crater rim. Crater rims — you gotta love ’em.”
More About Perseverance
A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover is characterizing the planet’s geology and past climate, to help pave the way for human exploration of the Red Planet and is the first mission to collect and cache Martian rock and regolith.
NASA’s Mars Sample Return Program, in cooperation with ESA (European Space Agency), is designed to send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.
The Mars 2020 Perseverance mission is part of NASA’s Mars Exploration Program portfolio and the agency’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.
NASA’s Jet Propulsion Laboratory, managed for the agency by Caltech in Pasadena, California, built and manages operations of the Perseverance rover.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA and SpaceX are launching the company’s 32nd commercial resupply services mission to the International Space Station later this month, bringing a host of new research to the orbiting laboratory. Aboard the SpaceX Dragon spacecraft are experiments focused on vision-based navigation, spacecraft air quality, materials for drug and product manufacturing, and advancing plant growth with less reliance on photosynthesis.
This and other research conducted aboard the space station advances future space exploration, including missions to the Moon and Mars, and provides many benefits to humanity.
Investigations traveling to the space station include:
Robotic spacecraft guidance
Smartphone Video Guidance Sensor-2 (SVGS-2) uses the space station’s Astrobee robots to demonstrate using a vision-based sensor developed by NASA to control a formation flight of small satellites. Based on a previous in-space demonstration of the technology, this investigation is designed to refine the maneuvers of multiple robots and integrate the information with spacecraft systems.
Potential benefits of this technology include improved accuracy and reliability of systems for guidance, navigation, and control that could be applied to docking crewed spacecraft in orbit and remotely operating multiple robots on the lunar or Martian surface.
Two of the space station’s Astrobee robots are used to test a vision-based guidance system for Smartphone Video Guidance Sensor (SVGS)NASA Protection from particles
During spaceflight, especially long-duration missions, concentrations of airborne particles must be kept within ranges safe for crew health and hardware performance. The Aerosol Monitors investigation tests three different air quality monitors in space to determine which is best suited to protect crew health and ensure mission success. The investigation also tests a device for distinguishing between smoke and dust. Aboard the space station, the presence of dust can cause false smoke alarms that require crew member response. Reducing false alarms could save valuable crew time while continuing to protect astronaut safety.
Better materials, better drugs
The DNA Nano Therapeutics-Mission 2 produces a special type of molecule formed by DNA-inspired, customizable building blocks known as Janus base nanomaterials. It also evaluates how well the materials reduce joint inflammation and whether they can help regenerate cartilage lost due to arthritis. These materials are less toxic, more stable, and more compatible with living tissues than current drug delivery technologies.
Environmental influences such as gravity can affect the quality of these materials and delivery systems. In microgravity, they are larger and have greater uniformity and structural integrity. This investigation could help identify the best formulations and methods for cost-effective in-space production. These nanomaterials also could be used to create novel systems targeting therapy delivery that improves patient outcomes with fewer side effects.

The newest Industrial Crystallization Cassette (ADSEP-ICC) investigation adds capabilities to an existing protein crystallization facility. The cassette can process more sample types, including tiny gold particles used in devices that detect cancer and other diseases or in targeted drug delivery systems. Microgravity makes it possible to produce larger and more uniform gold particles, which improves their use in research and real-life applications of technologies related to human health.
Helping plants grow
Rhodium USAFA NIGHT examines how tomato plants respond to microgravity and whether a carbon dioxide replacement can reduce how much space-grown plants depend on photosynthesis. Because photosynthesis needs light, which requires spacecraft power to generate, alternatives would reduce energy use. The investigation also examines whether using supplements increases plant growth on the space station, which has been observed in preflight testing on Earth. In future plant production facilities aboard spacecraft or on celestial bodies, supplements could come from available organic materials such as waste.
Understanding how plants adapt to microgravity could help grow food during long-duration space missions or harsh environments on Earth.
Hardware for the Rhodium Plant LIFE, which was the first in a series used to study how space affects plant growth.NASA Atomic clocks in space
An ESA (European Space Agency) investigation, Atomic Clock Ensemble in Space (ACES), examines fundamental physics concepts such as Einstein’s theory of relativity using two next-generation atomic clocks operated in microgravity. Results have applications to scientific measurement studies, the search for dark matter, and fundamental physics research that relies on highly accurate atomic clocks in space. The experiment also tests a technology for synchronizing clocks worldwide using global navigation satellite networks.
