In her decades of experience, she’s seen firsthand how students with physical challenges can face difficulties in connecting with lessons. She decided to tackle the issue head-on with her internship.
Ripollone supports the My NASA Data Program, which provides educational materials to interact with live data collected by NASA satellites, observatories, and sensors worldwide. As a NASA intern, she has worked to create physical materials with braille for students with- vision limitations.
“It’s a start for teachers,” Ripollone said. “Although every classroom is different, this helps to provide teachers a jumpstart to make engaging lesson plans centered around real NASA data.” Her NASA internship has excited and inspired her students, according to Ripollone. “My students have been amazed! I see their eyes open wide,” she said. “They say, ‘My teacher is working for NASA!'”
Felicia Haseleu: Improving Reading and Writing Skills
North Dakota teacher Felicia Haseleu never imagined she’d be a NASA intern until a colleague forwarded the opportunity to her inbox. A teacher on her 11th year, she has seen how COVID-19 has affected students: “It’s caused a regression in reading and writing ability,” a shared impact that was seen in students nationwide.
A science teacher passionate about reading and writing, Felicia set out to utilize these in the science curriculum. As an intern with My NASA Data, she’s prepared lesson plans that combine using the scientific method with creative writing, allowing students to strengthen their reading and writing skills while immersing themselves in science.
Haseleu anticipates her NASA internship will provide benefits inside and outside the classroom.
“It’s going to be awesome to return to the classroom with all of these materials,” she said. “Being a NASA intern has been a great experience! I’ve felt really supported and you can tell that NASA is all encompassing and supports one another. From the camaraderie to NASA investing in interns, it’s nice to feel valued by NASA.”

Credit: Teri Minami “I’ve never been a data-whiz; I’ve always connected with science hands-on or through art,” said NASA intern Teri Minami, a teacher of 10 years in coastal Virginia. She cites her personal experience in science to guide her to develop lessons using NASA data for neurodivergent students or those with a more artistic background.
Through her NASA internship, she aims to create lesson plans which allow students to engage first-hand with science while outdoors, such as looking at water quality data, sea level ice, and CO2 emissions, taking their own measurements, and doing their own research on top of that.
Although many people associate being an intern with being an undergraduate in college, NASA interns come from all ages and backgrounds. In 2024, the agency’s interns ranged in age from 16 to 61 and included high school students, undergraduates, graduate students, doctoral students, and teachers.

5 Min Read NASA Returns to Arctic Studying Summer Sea Ice Melt
NASA's Gulfstream III aircraft taxis on the runway at Pituffik Space Base as it begins one of its daily science flights for the ARCSIX mission. Credits: NASA/Gary Banziger What happens in the Arctic doesn’t stay in the Arctic, and a new NASA mission is helping improve data modeling and increasing our understanding of Earth’s rapidly changing climate. Changing ice, ocean, and atmospheric conditions in the northernmost part of Earth have a large impact on the entire planet. That’s because the Arctic region acts like Earth’s air conditioner.
Much of the Sun’s energy is transported from tropical regions of our planet by winds and weather systems into the Arctic where it is then lost to space. This process helps cool the planet.
The NASA-sponsored Arctic Radiation Cloud Aerosol Surface Interaction Experiment (ARCSIX) mission is flying three aircraft over the Arctic Ocean north of Greenland to study these processes. The aircraft are equipped with instruments to gather observations of surface sea ice, clouds, and aerosol particles, which affect the Arctic energy budget and cloud properties. The energy budget is the balance between the energy that Earth receives from the Sun and the energy the Earth loses to outer space.

This highlight video gives viewers a front row seat to a typical day on the ARCSIX mission from Pituffik Space Base as NASA's research scientists, instrument operators, and flight crews fly daily routes observing sea ice and clouds 750 miles north of the Arctic Circle in Greenland.NASA/Gary Banziger “More sea ice makes that air conditioning effect more efficient. Less sea ice lessens the Arctic’s cooling effect,” says Patrick Taylor, a climate scientist at NASA’s Langley Research Center in Hampton, Virginia. “Over the last 40 years, The Arctic has lost a significant amount of sea ice making the Arctic warm faster. As the Arctic warms and sea ice melts, it can cause ripple effects that impact weather conditions thousands of miles away, how fast our seas are rising, and how much flooding we get in our neighborhoods.”

The first series of flights took place in May and June as the seasonal melting of ice started. Flights began again on July 24 during the summer season, when sea ice melting is at its most intense.
“We can’t do this kind of Arctic science without having two campaigns,” said Taylor, the deputy science lead for ARCSIX. “The sea ice surface in the spring was very bright white and snow covered. We saw some breaks in the ice. What we will see in the second campaign is less sea ice and sea ice that is bare, with no snow. It will be covered with all kinds of melt ponds – pooling water on top of the ice – that changes the way the ice interacts with sunlight and potentially changes how the ice interacts with the atmosphere and clouds above.”
Sea ice and the snow on top of the ice insulate the ocean from the atmosphere, reflecting the Sun’s radiation back towards space, and helping to cool the planet. Less sea ice and darker surfaces result in more of the Sun’s radiation being absorbed at the surface or trapped between the surface and the clouds.

“This unique team of pilots, engineers, scientists, and aircraft can only be done by leveraging expertise from multiple NASA centers and our partners,” said Linette Boisvert, cryosphere lead for the mission from NASA’s Space Flight Center in Greenbelt, Maryland. “We gathered great data of the snow and ice pre-melt and at the onset of melt. I can’t wait to see the changes at the height of melt as we measure the same areas covered with melt ponds.”
NASA partnered with the University of Colorado Boulder for the ARCSIX mission, and the research team found some surprises in their early data analysis from the spring campaign. One potential discovery is something Taylor is calling a “sea ice sandwich”, when a younger layer of sea ice is caught in between two layers of older sea ice. Scientists also found more drizzle within the clouds than expected. Both observations will need further investigating once the data is fully processed.
A research scientist monitors data measurements in-flight during the spring campaign of the ARCSIX mission.NASA/Gary Banziger “A volcano erupted in Iceland, and we believe the volcanic aerosol plume was indicated by our models four days later,” Taylor said. “Common scientific knowledge tells us volcanic particles, like ash and sulfate, would have already been removed from the atmosphere. More work needs to be done, but our initial results suggest these particles might live in the atmosphere much longer than previously thought.”
Previous studies suggest that aerosol particles in clouds can influence sea ice melt. Data collected during ARCSIX’s spring flights showed the Arctic atmosphere had several aerosol particle layers, including wildfire smoke, pollution, and dust transported from Asia and North America.
“We got everything we hoped for and more in the first campaign,” Taylor added. “The data from this summer will help us better understand how clouds and sea ice behave. We’ll be able to use these results to improve predictive models. In the coming years, scientists will be able to better predict how to mitigate and adapt to the rapid changes in climate we’re seeing in the Arctic.”

Meet NASA Interns Shaping Future of Open Science
Intern Lena Young, whose work revolves around DEIA and open science, stands next to a NASA sign at NASA’s Earth Information Center in Washington, D.C. Photo courtesy of Lena Young Students at NASA’s Office of the Chief Science Data Officer (OCSDO) are working to promote open science during the summer 2024 internship session. Their projects fall across a variety of areas, including user experience, policy, and DEIA (Diversity, Equity, Inclusion, and Accessibility).
Lena Young: Increasing DEIA Engagement
Lena Young, a doctoral candidate in the Creative Leadership for Innovation and Change program at the University of the Virgin Islands in St. Thomas, envisions equitable space societies 100 – 300 years in the future as part of her dissertation. Her NASA internship project involves researching ways to make science more accessible for different groups and interacting with NASA leadership to assess how well they are engaging historically underserved or excluded communities.
Young also worked with her mentors to find overlap between her internship project and her PhD work as a futurist. “In 30 years, once NASA has achieved their goals, what would open science look like?” Young said. “I want to see what different futures I can create for open science and DEIA engagement.”
Becca Michelson: Advancing Policy
Becca Michelson has a passion for increasing the availability of scientific information. A soon-to-be-graduate in physics and astronomy from Smith College in Northampton, Massachusetts, she was drawn to an internship role in researching the current state of open science policy for the OCSDO. By understanding the challenges and opportunities in this area, she’s helping NASA better support researchers in making their science accessible to all.
“Open science makes this a more inclusive field, where if I’m an early career scientist, I can build on the science that other people who are experts in the field have done,” Michelson said. In the future, she hopes to implement open science principles into her own research in astronomy, drawing from the best practices she has learned at NASA.
Salma Elsayed-Ali: Bridging Science, User Experience
Salma Elsayed-Ali is on a mission to bridge the gap between science and usability. She recently completed her PhD in Information Science with a focus on Human-Computer Interaction from the University of Maryland, College Park. Her NASA internship project involves conducting UI/UX (User Interface/User Experience) research on some of the OCSDO’s scientific products, most notably the Open Science 101 online course.
Elsayed-Ali became interested in open science during the height of the COVID-19 pandemic, when she conducted UI/UX research on open data sites that provided the public with real-time information about the spread of the virus. This experience sparked her interest in helping users reap the benefits of open science as part of an internship with NASA.
In improving the OCSDO’s open science interfaces, Elsayed-Ali has acted as the product lead on a UI/UX research project for the first time. “I was drawn to this project as it was an opportunity to advocate for both end users and the advancement of open science,” Elsayed-Ali said. “I have really enjoyed brainstorming creative, practical solutions that enhance the user experience and simultaneously save the product team time and resources.”
By helping open science at NASA to thrive, these interns are ushering in a future of greater access to data and scientific research. Learn more about NASA internships at the NASA Internship Programs page.

This artist’s concept shows how the universe might have looked when it was less than a billion years old, about 7 percent of its current age. Star formation voraciously consumed primordial hydrogen, churning out myriad stars at an unprecedented rate. NASA’s Nancy Grace Roman Space Telescope will peer back to the universe’s early stages to understand how it transitioned from being opaque to the brilliant starscape we see today.NASA, ESA, and A. Schaller (for STScI) 0:00 / 0:00
Your browser does not support the audio element. Today, enormous stretches of space are crystal clear, but that wasn’t always the case. During its infancy, the universe was filled with a “fog” that made it opaque, cloaking the first stars and galaxies. NASA’s upcoming Nancy Grace Roman Space Telescope will probe the universe’s subsequent transition to the brilliant starscape we see today –– an era known as cosmic dawn.
“Something very fundamental about the nature of the universe changed during this time,” said Michelle Thaller, an astrophysicist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Thanks to Roman’s large, sharp infrared view, we may finally figure out what happened during a critical cosmic turning point.”
Lights Out, Lights On
Shortly after its birth, the cosmos was a blistering sea of particles and radiation. As the universe expanded and cooled, positively charged protons were able to capture negatively charged electrons to form neutral atoms (mostly hydrogen, plus some helium). That was great news for the stars and galaxies the atoms would ultimately become, but bad news for light!
It likely took a long time for the gaseous hydrogen and helium to coalesce into stars, which then gravitated together to form the first galaxies. But even when stars began to shine, their light couldn’t travel very far before striking and being absorbed by neutral atoms. This period, known as the cosmic dark ages, lasted from around 380,000 to 200 million years after the big bang.
Then the fog slowly lifted as more and more neutral atoms broke apart over the next several hundred million years: a period called the cosmic dawn.
“We’re very curious about how the process happened,” said Aaron Yung, a Giacconi Fellow at the Space Telescope Science Institute in Baltimore, who is helping plan Roman’s early universe observations. “Roman’s large, crisp view of deep space will help us weigh different explanations.”

It could be that early galaxies may be largely to blame for the energetic light that broke up the neutral atoms. The first black holes may have played a role, too. Roman will look far and wide to examine both possible culprits.
“Roman will excel at finding the building blocks of cosmic structures like galaxy clusters that later form,” said Takahiro Morishita, an assistant scientist at Caltech/IPAC in Pasadena, California, who has studied cosmic dawn. “It will quickly identify the densest regions, where more ‘fog’ is being cleared, making Roman a key mission to probe early galaxy evolution and the cosmic dawn.”
The earliest stars were likely starkly different from modern ones. When gravity began pulling material together, the universe was very dense. Stars probably grew hundreds or thousands of times more massive than the Sun and emitted lots of high-energy radiation. Gravity huddled up the young stars to form galaxies, and their cumulative blasting may have once again stripped electrons from protons in bubbles of space around them.
“You could call it the party at the beginning of the universe,” Thaller said. “We’ve never seen the birth of the very first stars and galaxies, but it must have been spectacular!”
But these heavyweight stars were short-lived. Scientists think they quickly collapsed, leaving behind black holes –– objects with such extreme gravity that not even light can escape their clutches. Since the young universe was also smaller because it hadn’t been expanding very long, hordes of those black holes could have merged to form even bigger ones –– up to millions or even billions of times the Sun’s mass.
Supermassive black holes may have helped clear the hydrogen fog that permeated the early universe. Hot material swirling around black holes at the bright centers of active galaxies, called quasars, prior to falling in can generate extreme temperatures and send off huge, bright jets of intense radiation. The jets can extend for hundreds of thousands of light-years, ripping the electrons from any atom in their path.
NASA’s James Webb Space Telescope is also exploring cosmic dawn, using its narrower but deeper view to study the early universe. By coupling Webb’s observations with Roman’s, scientists will generate a much more complete picture of this era.
So far, Webb is finding more quasars than anticipated given their expected rarity and Webb’s small field of view. Roman’s zoomed-out view will help astronomers understand what’s going on by seeing how common quasars truly are, likely finding tens of thousands compared to the handful Webb may find.
This view from the James Webb Space Telescope contains more than 20,000 galaxies. Researchers analyzed 117 galaxies that all existed approximately 900 million years after the big bang. They focused on 59 galaxies that lie in front of quasar J0100+2802, an active supermassive black hole that acts like a beacon, located at the center of the image above appearing tiny and pink with six prominent diffraction spikes. The team studied both the galaxies themselves and the illuminated gas surrounding them, which was lit up by the quasar’s bright light. The observation sheds light on how early galaxies cleared the “fog” around them, eventually leading to today’s clear and expansive views.NASA, ESA, CSA, Simon Lilly (ETH Zürich), Daichi Kashino (Nagoya University), Jorryt Matthee (ETH Zürich), Christina Eilers (MIT), Rob Simcoe (MIT), Rongmon Bordoloi (NCSU), Ruari Mackenzie (ETH Zürich); Image Processing: Alyssa Pagan (STScI), Ruari Macken “With a stronger statistical sample, astronomers will be able to test a wide range of theories inspired by Webb observations,” Yung said.
Peering back into the universe’s first few hundred million years with Roman’s wide-eyed view will also help scientists determine whether a certain type of galaxy (such as more massive ones) played a larger role in clearing the fog.
“It could be that young galaxies kicked off the process, and then quasars finished the job,” Yung said. Seeing the size of the bubbles carved out of the fog will give scientists a major clue. “Galaxies would create huge clusters of bubbles around them, while quasars would create large, spherical ones. We need a big field of view like Roman’s to measure their extent, since in either case they’re likely up to millions of light-years wide –– often larger than Webb’s field of view.”
Roman will work hand-in-hand with Webb to offer clues about how galaxies formed from the primordial gas that once filled the universe, and how their central supermassive black holes influenced galaxy and star formation. The observations will help uncover the cosmic daybreakers that illuminated our universe and ultimately made life on Earth possible.
The Nancy Grace Roman Space Telescope is managed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, with participation by NASA’s Jet Propulsion Laboratory and Caltech/IPAC in Southern California, the Space Telescope Science Institute in Baltimore, and a science team comprising scientists from various research institutions. The primary industrial partners are BAE Systems, Inc in Boulder, Colorado; L3Harris Technologies in Rochester, New York; and Teledyne Scientific & Imaging in Thousand Oaks, California.
