Linette Boisvert turned a childhood love of snow into a career as a sea ice scientist studying climate change.
Name: Linette Boisvert
Title: Assistant Lab Chief, Cryospheric Sciences Branch, and Deputy Project Scientist for the Aqua Satellite
Formal Job Classification: Sea Ice Scientist
Organization: Cryospheric Science Branch, Science Directorate (Code 615)
“When it snowed, school was cancelled so I loved winter weather, and I was fascinated how weather could impact our daily lives,” said Linette. “One of my undergraduate classes had a guest lecturer talk about the Arctic and that is when decided that I wanted to become an Arctic scientist.”Photo credit: NASA/Kyle Krabill What do you do and what is most interesting about your role here at Goddard?
As a sea ice scientist, I study interactions between the sea ice and the atmosphere. I’m interested in how the changing sea ice conditions and loss of Arctic ice are affecting the atmospheric conditions in the Artic.
Why did you become a sea ice scientist? What is your educational background?
I grew up in Maryland. When it snowed, school was cancelled so I loved winter weather, and I was fascinated how weather could impact our daily lives. One of my undergraduate classes had a guest lecturer talk about the Arctic and that is when decided that I wanted to become an Arctic scientist. This also coincided with the Arctic sea ice minimum in 2007, at the time, a record low.
In 2008, I got a B.S. in environmental science with a minor in math from the University of Maryland, Baltimore County (UMBC). I received my master’s and, in 2013, got a Ph.D. in atmospheric and oceanic sciences from the University of Maryland, College Park.
How did you come to Goddard?
My doctorate advisor worked at Goddard. In 2009, he brought me into Goddard’s lab to do my Ph.D. research. I became a post-doctorate in 2013, an assistant research scientist in 2016 (employed by UMD/ESSIC) and, in 2018, a civil servant.

From 2018 to 2020, I was the deputy project scientist for NASA’s largest and longest running airborne campaign, Operation IceBridge. This involved flying aircraft with scientific instruments over both land ice and sea ice in the Arctic and Antarctic. Every spring, we would set up a base camp in a U.S. Air Force base in Greenland and fly over parts of the sea ice over Greenland and the Arctic, and in the fall we would base out of places like Punta Arenas, Chile, and Hobart, Australia, to fly over the Antarctic.
We would fly low, at 1,500 feet above the surface. It is very, very cool to see the ice firsthand. It is so pretty, so vast, and complex. We would spend 12 hours a day on a plane just surveying the ice.
Being based out of Greenland is very remote. Everything is white. Everything looks like it is closer than it is. You do not have a point of reference for any perspective. It is very quiet. There is no background ambient noise. You do not hear bugs, birds, or cars, just quiet.
Our team was about 20 people. Other people live at the base. The campaigns lasted six to eight weeks. I was there about three to four weeks each time. Many of the group had been doing these campaigns for a decade. I felt like I had joined a family. In the evenings, we would often cook dinner together and play games. On days we could not fly, we would go on adventures together like visiting a glacier or hiking. We saw musk ox, Arctic fox, Arctic hares, and seals.
How did it feel to become the deputy project scientist for the Aqua satellite, which provided most of the data you used for your doctorate and publications?
In January 2023, I became the deputy project scientist for the Aqua satellite, which launched in 2002. Aqua measures the Earth’s atmospheric temperature, humidity, and trace gases. Most of my doctorate and publications used data from Aqua to look at how the sea ice loss in the Arctic is allowing for excess heat and moisture from the ocean to move into the atmosphere resulting in a warmer and wetter Arctic.
I am honored. I feel like I have come full circle. The team welcomed me into the mission and taught me a lot of things. I am grateful to be working with such a brilliant, hardworking team.
Who is your science hero?
My father encouraged me to get a doctorate in science. My father has a doctorate in computer science and math. He works at the National Institute of Standards and Technology. I wanted to be like him when I was growing up. I came close, working at NASA, another part of the federal government. My mother, a French pastry chef, always kept me well fed.

He thinks I am more of a superstar than he was at my age, but I do not believe it. My mother is also proud and continues to keep me well fed.
Who is your Goddard mentor?
Claire Parkinson, now an emeritus, was the project scientist for Aqua since its inception. When she retired, she encouraged me to apply for the deputy position. She had confidence in me which gave me the confidence to apply for the position. She is still always available to answer any questions. I am very thankful that she has been there for me throughout my career.
What advice do you give to those you mentor?
I recently began advising young scientists; one undergraduate student, two graduate students, and one post-doctoral scientist. We meet weekly as a group and have one-on-one meetings when appropriate. They share their progress on their work. Sometimes we practice presentations they are about to give.
It is sometimes hard starting out to think that you are smart because Goddard is full of so many smart people. I tell them that they are just as capable when it comes to their research topic. I tell them that they fit in well with the Goddard community. I want to create a comfortable, respectful, and inclusive environment so that they remain in science.
What do you do for fun?
I enjoy running and paddle boarding with my dog Remi, my long-haired dachshund. I enjoy reading. I love to travel and be around friends and family. But I do not enjoy cooking, so I do not bake French pastries like my mom.
Where do you see yourself in five years?
I hope to continue doing research including field work. It would be great if some of my students finished their studies and joined my lab. I hope that I am still making people proud of me.

The world is full of mysterious places, and Vottovaara Mountain in Russia's Republic of Karelia is one of them. This site has been revered for thousands of years by ancient Saami tribes and shamans, who considered it a sacred place surrounded with powerful energy.
Image credit: Universe Inside You
Vottovaara is home to numerous strange megalithic structures and ruins that many believe couldn't have formed naturally. Among these are around 1,600 sacred stones, known as "seids," arranged in a puzzling pattern. These stones, often unusually shaped, are precariously balanced on small rocks in ways that defy simple explanations. While scientists suggest that this was the result of natural processes during the Ice Age, the sheer number and precision of these balanced stones challenge the idea that they occurred by chance.
Another intriguing feature of Vottovaara is a structure referred to as "the well," which locals believe to be an ancient, man-made water reservoir.
As you climb Vottovaara, you'll notice an eerie transformation in the trees. None of the trees on the summit are older than a few decades, and while young pines and firs start growing normally, they soon begin to twist and deform in bizarre ways. This phenomenon is thought to be caused by some unknown energy affecting the trees.
Known as Death Mountain, Vottovaara also is believed to be connected to ancient spirits that are said to inhabit the area, adding to its aura of mystery.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The LZR Racer reduces skin friction drag by covering more skin than traditional swimsuits. Multiple pieces of the water-resistant and extremely lightweight LZR Pulse fabric connect at ultrasonically welded seams and incorporate extremely low-profile zippers to keep viscous drag to a minimum.Credit: SpeedoUSA A supersonic airplane and a competitive swimmer have much more in common than people might realize; both have to contend with the slowing influence of drag. NASA’s Aeronautics Research Mission Directorate focuses primarily on improving flight efficiency and fluid dynamics, especially the forces of pressure and drag, which are the same for bodies moving through air as for bodies moving through water. Shortly after the 2004 Olympics, Los Angeles-based SpeedoUSA, also known as Speedo, asked NASA’s Langley Research Center to help design a swimsuit with reduced surface drag. The manufacturer sought a partnership with NASA because of the agency’s expertise in fluid dynamics.
In competitive swimming, where every hundredth of a second counts, achieving the best possible drag reduction is crucially important. Researchers at NASA began flat plate testing of fabrics, using a small wind tunnel developed for earlier research on low-speed viscous drag reduction and collaborated over the next few years with Speedo to design the LZR Racer swimsuit.
Researcher Corey Diebler inspects a model of the supersonic X-59 after a test in Langley Research Center’s 12 foot wind tunnel. Wind tunnel testing at Langley enabled Speedo’s LZR Racer to achieve its excellent underwater performance.NASA/David C. Bowman. NASA and Speedo performed tests on traditionally sewn seams, ultrasonically welded seams, and the fabric alone, which gave Speedo a baseline for reducing drag caused by seams and helped identify problem areas. NASA wind tunnel results helped Speedo create a bonding system that eliminates seams and reduces drag. The results also showed that a low-profile zipper ultrasonically bonded into the fabric inside the suit generated eight percent less drag in wind tunnel tests than a standard zipper. Low-profile seams and zippers were a crucial component in the LZR Racer, because the suit consists of multiple connecting fabric pieces—instead of just a few sewn pieces such as found in traditional suits—that provide extra compression for maximum efficiency.
In March 2008, the LZR Racer made its mark on the world of competitive swimming. Athletes donning this innovative swimsuit shattered 13 world records, a testament to the power of collaboration between NASA and Speedo. While the original LZR Racer is no longer used in competition because of the advantage it gave wearers, its legacy lives on in today’s swimsuits approved by World Aquatics, the governing body for international competitive swimming.

5 Min Read Eileen Collins Broke Barriers as America’s First Female Space Shuttle Commander
Astronauts Eileen M. Collins, mission commander and Jeffrey S. Ashby, pilot, peruse checklists on Columbia's middeck during the STS-93 mission. Credits: NASA At the end of February 1998, Johnson Space Center Deputy Director James D. Wetherbee called Astronaut Eileen Collins to his office in Building 1. He told her she had been assigned to command STS-93 and went with her to speak with Center Director George W.S. Abbey who informed her that she would be going to the White House the following week.
Selecting a female commander to fly in space was a monumental decision, something the space agency recognized when they alerted the president of the United States. First Lady Hillary Clinton wanted to publicly announce the flight to the American people along with her husband President William J. Clinton and NASA Administrator Daniel S. Goldin.
President William Jefferson Clinton and First Lady Hillary Rodham Clinton with Eileen Collins in the Oval Office.Sharon Farmer and White House Photograph Office At that event, on March 5, 1998, the First Lady noted what a change it would be to have a female in the commander’s seat. Referencing Neil A. Armstrong’s first words on the Moon, Clinton proclaimed, “Collins will take one big step forward for women and one giant leap for humanity.” Collins, a military test pilot and shuttle astronaut, was about to break one of the last remaining barriers for women at NASA by being assigned a position previously filled by men only. Clinton went on to reflect on her own experience with the space agency when she explained how in 1962, at the age of 14, she had written to NASA and asked about the qualifications to become an astronaut. NASA responded that women were not being considered to fly space missions. “Well, times have certainly changed,” she said wryly.
Eileen Collins’ assignment as the first female shuttle commander was front page news in the March 13, 1998 issue of Johnson Space Center’s Space News Roundup.NASA The same year Hillary Clinton inquired about the astronaut corps, a special subcommittee of the U.S. House of Representatives Committee on Science and Astronautics held hearings on the issue of sexual discrimination in the selection of astronauts. Astronaut John H. Glenn, who had flown that February in 1962, justified women’s exclusion from the corps. “I think this gets back to the way our social order is organized really. It is just a fact. The men go off and fight the wars and fly the airplanes and come back and help design and build and test them. The fact that women are not in this field is a fact of our social order. It may be undesirable.” Attitudes about women’s place in society, not just at NASA, were stubbornly hard to break. It would be 16 years before the agency selected its first class of astronauts that included women.
Astronaut Eileen M. Collins looks over a checklist at the commander’s station on the forward flight deck of the space shuttle Columbia on July 23, 1999, the first day of the mission. The most important event of this day was the deployment of the Chandra X-Ray Observatory.NASA By 1998, views about women’s roles had changed substantially, as demonstrated by the naming of the first female shuttle commander. The agency even commissioned a song for the occasion: “Beyond the Sky,” by singer-songwriter Judy Collins. NASA dedicated the historic mission’s launch to America’s female aviation pioneers from the Ninety-Nines—an international organization of women pilots—to the Women Airforce Service Pilots (WASPs), women who ferried aircraft for the military during World War II. Collins also extended an invitation to the women who had participated in Randy Lovelace’s Woman in Space Program, where women went through the same medical and psychological tests as the Mercury 7 astronauts; the press commonly refers to these women as the Mercury 13. (Commander Collins had thanked both the WASPs and the Mercury 13 for paving the way and inspiring her career in aviation and spaceflight in her White House speech.)
In a way, it's like my dream come true.
Betty Skelton Frankman
Pioneering Woman Aviator
In a group interview with several of the WASPs in Florida, just before launch, Mary Anna “Marty” Martin Wyall explained why they came. “Eileen Collins was one of those women that has always looked at us as being her mentors, and we just think she’s great. That’s why we want to come see her blast off.” Betty Skelton Frankman expressed just how proud she was of Collins, and how NASA’s first female commander would be fulfilling her dream to fly in space. “In a way,” she said, “it’s like my dream come true.” In the ‘60s it was not possible for a woman to fly in space because none met the requirements as laid out by NASA. But by the end of the twentieth century, women had been in the Astronaut Office for 20 years, and opportunities for women had grown as women were selected as pilot astronauts. NASA named its second and only other female space shuttle commander, Pamela A. Melroy, to STS-120, and Peggy A. Whitson went on to command the International Space Station. Melroy and Whitson shook hands in space, when their missions coincided, for another historic first—two women commanding space missions at the same time.
Twenty-five years ago, Eileen Collins’ command broke down barriers in human spaceflight. As the First Lady predicted, her selection led to other opportunities for women astronauts. More women continue to command spaceflight missions, including Expedition 65 Commander Shannon Walker and Expedition 68 Commander Samantha Cristoforetti. More importantly, Collins became a role model for young people interested in aviation, engineering, math, science, and technology. Her career demonstrated that there were no limits if you worked hard and pursued your passion.

The latest crew chosen by NASA to venture on a simulated trip to Mars inside the agency’s Human Exploration Research Analog. From left are Sergii Iakymov, Erin Anderson, Brandon Kent, and Sarah Elizabeth McCandless.Credit: C7M3 Crew NASA selected a new team of four research volunteers to participate in a simulated mission to Mars within HERA (Human Exploration Research Analog) at the agency’s Johnson Space Center in Houston.
Erin Anderson, Sergii Iakymov, Brandon Kent, and Sarah Elizabeth McCandless will begin their simulated trek to Mars on Friday, Aug. 9. The volunteer crew members will stay inside the 650-square-foot habitat for 45 days, exiting Monday, Sept. 23 after a simulated “return” to Earth. Jason Staggs and Anderson Wilder will serve as alternate crew members.
The HERA missions offer scientific insights into how people react to the type of isolation, confinement, work and life demands, and remote conditions astronauts might experience during deep space missions.
The facility supports more frequent, shorter-duration simulations in the same building as CHAPEA (Crew Health and Performance Analog). This crew is the third group of volunteers to participate in a simulated Mars mission in HERA this year. The most recent crew completed its HERA mission on June 24. In total, there will be four analog missions in this series.
During this summer’s simulation, participants will perform a mix of science and operational tasks, including harvesting plants from a hydroponic garden, growing shrimp, deploying a small, cube-shaped satellite (CubeSat) to simulate gathering virtual data for analysis, “walking” on the surface of Mars using virtual reality goggles, and flying simulated drones on the simulated Mars surface. The team members also will encounter increasingly longer communication delays with Mission Control throughout their mission, culminating in five-minute lags as they “near” Mars. Astronauts traveling to Mars may experience communications delays of up to 20 minutes.
NASA’s Human Research Program will conduct 18 human health experiments during each of the 2024 HERA missions. Collectively, the studies explore how a Mars-like journey may affect the crew members’ mental and physical health. The work also will allow scientists to test certain procedures and equipment designed to keep astronauts safe and healthy on deep space missions.
