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.”

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.”
As the Arctic warms and sea ice melts, it can cause ripple effects…thousands of miles away.

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.

A pilot's view of Arctic sea ice from NASA's P-3 Orion aircraft during NASA's ARCSIX airborne science mission flights in June.NASA/Gary Banziger Understanding this relationship, and the role clouds play in the system, will help scientists improve satellite data and better predict future changes in the Arctic climate.
“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.”

Crane operator Rebekah Tolatovicz, a shift mechanical technician lead for Artic Slope Regional Corporation at NASA’s Kennedy Space Center in Florida, operates a 30-ton crane to lift the agency’s Artemis II Orion spacecraft out of the recently renovated altitude chamber to the Final Assembly and Systems Testing, or FAST, cell inside NASA Kennedy’s Neil A. Armstrong Operations and Checkout Building on April 27.
During her most recent lift July 10, Tolatovicz helped transfer Orion back to the FAST cell following vacuum chamber qualification testing in the altitude chamber earlier this month. This lift is one of around 250 annual lifts performed at NASA Kennedy by seven operator/directors and 14 crane operators on the ASRC Orion team.
“At the time of the spacecraft lift, I focus solely on what’s going on in the moment of the operation,” explains Tolatovicz. “Listening for the commands from the lift director, making sure everyone is safe, verifying the vehicle is clear, and ensuring the crane is moving correctly.”
All Orion crane operators are certified after classroom and on-the-job training focusing on areas such as rigging, weight and center of gravity, mastering crane controls, crane securing, assessing safety issues, and emergency procedures. Once certified, they progress through a series of the different lifts required for Orion spacecraft operations, from simple moves to the complex full spacecraft lift.
“It’s not until after the move is complete and the vehicle is secured that I have a moment to think about how awesome it is to be a part of history on the Orion Program and do what I get to do every day with a team of the most amazing people,” Tolatovicz said.
