Womens History Month - Blog Posts

“The formula for doing a good job in photography is to think like a poet.” — Imogen Cunningham #WomensHistoryMonth 📷My Signature, 1973 #ICPCollections

LaRue Burbank, mathematician and computer, is just one of the many women who were instrumental to NASA missions.

4 Little Known Women Who Made Huge Contributions to NASA

Women have always played a significant role at NASA and its predecessor NACA, although for much of the agency’s history, they received neither the praise nor recognition that their contributions deserved. To celebrate Women’s History Month – and properly highlight some of the little-known women-led accomplishments of NASA’s early history – our archivists gathered the stories of four women whose work was critical to NASA’s success and paved the way for future generations.

LaRue Burbank: One of the Women Who Helped Land a Man on the Moon

LaRue Burbank was a trailblazing mathematician at NASA. Hired in 1954 at Langley Memorial Aeronautical Laboratory (now NASA’s Langley Research Center), she, like many other young women at NACA, the predecessor to NASA, had a bachelor's degree in mathematics. But unlike most, she also had a physics degree. For the next four years, she worked as a "human computer," conducting complex data analyses for engineers using calculators, slide rules, and other instruments. After NASA's founding, she continued this vital work for Project Mercury.

In 1962, she transferred to the newly established Manned Spacecraft Center (now NASA’s Johnson Space Center) in Houston, becoming one of the few female professionals and managers there.  Her expertise in electronics engineering led her to develop critical display systems used by flight controllers in Mission Control to monitor spacecraft during missions. Her work on the Apollo missions was vital to achieving President Kennedy's goal of landing a man on the Moon.

Eilene Galloway: How NASA became… NASA

Eilene Galloway wasn't a NASA employee, but she played a huge role in its very creation. In 1957, after the Soviet Union launched Sputnik, Senator Richard Russell Jr. called on Galloway, an expert on the Atomic Energy Act, to write a report on the U.S. response to the space race. Initially, legislators aimed to essentially re-write the Atomic Energy Act to handle the U.S. space goals. However, Galloway argued that the existing military framework wouldn't suffice – a new agency was needed to oversee both military and civilian aspects of space exploration. This included not just defense, but also meteorology, communications, and international cooperation.

Her work on the National Aeronautics and Space Act ensured NASA had the power to accomplish all these goals, without limitations from the Department of Defense or restrictions on international agreements. Galloway is even to thank for the name "National Aeronautics and Space Administration", as initially NASA was to be called “National Aeronautics and Space Agency” which was deemed to not carry enough weight and status for the wide-ranging role that NASA was to fill.

Barbara Scott: The “Star Trek Nerd” Who Led Our Understanding of the Stars

A self-described "Star Trek nerd," Barbara Scott's passion for space wasn't steered toward engineering by her guidance counselor. But that didn't stop her!  Fueled by her love of math and computer science, she landed at Goddard Spaceflight Center in 1977.  One of the first women working on flight software, Barbara's coding skills became instrumental on missions like the International Ultraviolet Explorer (IUE) and the Thermal Canister Experiment on the Space Shuttle's STS-3.  For the final decade of her impressive career, Scott managed the flight software for the iconic Hubble Space Telescope, a testament to her dedication to space exploration.

Dr. Claire Parkinson: An Early Pioneer in Climate Science Whose Work is Still Saving Lives

Dr. Claire Parkinson's love of math blossomed into a passion for climate science. Inspired by the Moon landing, and the fight for civil rights, she pursued a graduate degree in climatology.  In 1978, her talents landed her at Goddard, where she continued her research on sea ice modeling. But Parkinson's impact goes beyond theory.  She began analyzing satellite data, leading to a groundbreaking discovery: a decline in Arctic sea ice coverage between 1973 and 1987. This critical finding caught the attention of Senator Al Gore, highlighting the urgency of climate change.

Parkinson's leadership extended beyond research.  As Project Scientist for the Aqua satellite, she championed making its data freely available. This real-time information has benefitted countless projects, from wildfire management to weather forecasting, even aiding in monitoring the COVID-19 pandemic. Parkinson's dedication to understanding sea ice patterns and the impact of climate change continues to be a valuable resource for our planet.

It’s Girl Scout Day! March 12, 2024, is the 112th birthday of Girl Scouts in the United States, and to celebrate, we’re sharing a lithograph of the Girl Scout alumnae who became NASA astronauts.

Girl Scouts learn to work together, build community, embrace adventurousness and curiosity, and develop leadership skills—all of which come in handy as an astronaut. For example, former Scouts Christina Koch and Jessica Meir worked together to make history on Oct. 18, 2019, when they performed the first all-woman spacewalk.

Pam Melroy is one of only two women to command a space shuttle and became NASA’s deputy administrator on June 21, 2021.

Nicole Mann was the first Indigenous woman from NASA to go to space when she launched to the International Space Station on Oct. 5, 2022. Currently, Loral O’Hara is aboard the space station, conducting science experiments and research.

Participating in thoughtful activities in leadership and STEM in Girl Scouts has empowered and inspired generations of girls to explore space, and we can’t wait to meet the future generations who will venture to the Moon and beyond.

Cosmic Alphabet Soup: Classifying Stars

If you’ve spent much time stargazing, you may have noticed that while most stars look white, some are reddish or bluish. Their colors are more than just pretty – they tell us how hot the stars are. Studying their light in greater detail can tell us even more about what they’re like, including whether they have planets. Two women, Williamina Fleming and Annie Jump Cannon, created the system for classifying stars that we use today, and we’re building on their work to map out the universe.

By splitting starlight into spectra – detailed color patterns that often feature lots of dark lines – using a prism, astronomers can figure out a star’s temperature, how long it will burn, how massive it is, and even how big its habitable zone is. Our Sun’s spectrum looks like this:

Astronomers use spectra to categorize stars. Starting at the hottest and most massive, the star classes are O, B, A, F, G (like our Sun), K, M. Sounds like cosmic alphabet soup! But the letters aren’t just random – they largely stem from the work of two famous female astronomers.

Williamina Fleming, who worked as one of the famous “human computers” at the Harvard College Observatory starting in 1879, came up with a way to classify stars into 17 different types (categorized alphabetically A-Q) based on how strong the dark lines in their spectra were. She eventually classified more than 10,000 stars and discovered hundreds of cosmic objects!

That was back before they knew what caused the dark lines in spectra. Soon astronomers discovered that they’re linked to a star’s temperature. Using this newfound knowledge, Annie Jump Cannon – one of Fleming’s protégés – rearranged and simplified stellar classification to include just seven categories (O, B, A, F, G, K, M), ordered from highest to lowest temperature. She also classified more than 350,000 stars!

Type O stars are both the hottest and most massive in the new classification system. These giants can be a thousand times bigger than the Sun! Their lifespans are also around 1,000 times shorter than our Sun’s. They burn through their fuel so fast that they only live for around 10 million years. That’s part of the reason they only make up a tiny fraction of all the stars in the galaxy – they don’t stick around for very long.

As we move down the list from O to M, stars become progressively smaller, cooler, redder, and more common. Their habitable zones also shrink because the stars aren’t putting out as much energy. The plus side is that the tiniest stars can live for a really long time – around 100 billion years – because they burn through their fuel so slowly.

Astronomers can also learn about exoplanets – worlds that orbit other stars – by studying starlight. When a planet crosses in front of its host star, different kinds of molecules in the planet’s atmosphere absorb certain wavelengths of light.

By spreading the star’s light into a spectrum, astronomers can see which wavelengths have been absorbed to determine the exoplanet atmosphere’s chemical makeup. Our James Webb Space Telescope will use this method to try to find and study atmospheres around Earth-sized exoplanets – something that has never been done before.

Our upcoming Nancy Grace Roman Space Telescope will study the spectra from entire galaxies to build a 3D map of the cosmos. As light travels through our expanding universe, it stretches and its spectral lines shift toward longer, redder wavelengths. The longer light travels before reaching us, the redder it becomes. Roman will be able to see so far back that we could glimpse some of the first stars and galaxies that ever formed.

Leadership, service, being prepared and doing your best – these qualities are exemplified by our astronauts, but are also shared by the Girl Scouts! Our astronaut corps has many scout alumnae, and over the years they’ve been breaking barriers and making names for themselves at NASA.

March 12, 2021 marks the 109th birthday of Girl Scouts in the United States, which has been inspiring generations of girls through leadership and STEM (science, technology, engineering and mathematics) activities to empower the explorers of today and tomorrow. To celebrate, we’re highlighting some of our Girl Scout alumnae over the years!

NASA astronaut and Girl Scout alumna Sunita Williams, who served as an International Space Station commander and spent 322 days in space during two spaceflight expeditions.

Former Scouts have served as crew members on numerous spaceflight missions.

From left: Susan Helms, the first female International Space Station crew member; Eileen Collins, the first woman to pilot and command a space shuttle; and Dr. Kathy Sullivan, the first American woman to perform a spacewalk.

Former Girl Scouts flew on more than one-third of the space shuttle missions and were pioneering forces as women began making their mark on human spaceflight. The first female crew member to serve on the International Space Station, the first to pilot and command a space shuttle and the first American woman to spacewalk were all Scout alumnae. 

They continue to break records, such as the first three all-woman spacewalks... 

Girl Scout alumnae and NASA astronauts Christina Koch and Jessica Meir made history when they conducted the first ever all-woman spacewalk on Oct.18, 2019. They went on to complete two more spacewalks, successfully completing their task of upgrading the space station’s battery charge/discharge unit. Christina and Jessica’s historic spacewalk was a testament to the growing number of women (and Girl Scouts) joining our astronaut corps; it is a milestone worth celebrating as we look forward to putting the first woman on the Moon with our Artemis Program! 

....and the longest spaceflight ever by a woman!

NASA astronaut Christina Koch smiles for a selfie while completing tasks during a spacewalk outside the International Space Station.

Koch went on to seal her name in the record books by surpassing Peggy Whitson’s record for the longest single spaceflight in history by a woman!

Understanding how the human body adjusts to things like weightlessness, radiation and bone-density loss is crucial as we look forward to embarking on long-duration spaceflights to the Moon and Mars. Thanks to former astronaut Scott Kelly’s Year in Space mission, we’ve been able to observe these changes on a biological male. Now, thanks to Christina’s mission, we are able to observe these changes on a biological female. 

Girl Scout alumnae will also help lead human exploration farther than ever before as members of our Artemis generation!

On January 10, 2020 we welcomed 11 new astronauts to our ranks – including three Girl Scout alumnae! As part of the first-ever class of astronauts under our Artemis lunar exploration program, Kayla Barron, Jessica Watkins and Loral O’Hara are now qualified for assignments including long-duration missions to the International Space Station, the Moon and Mars.

They took a moment after graduation to share inspiration and insight for current and future Scouts!

Q: A question from the Girl Scouts: What inspires you?

A: “Being a part of an awesome team has always been what inspires me. Whether it’s your Girl Scout troop, a sports team, your class – I think for me always the people around me who push me to succeed and support me when I make mistakes and help me become my best self is what inspires me to show up and do my best.” - NASA astronaut Kayla Barron 

Q: How has being a Girl Scout helped you in becoming an astronaut?

A: “Being in the Girl Scouts when I was younger was really cool because, well, first it was just a group of my friends who got to do a lot of different things together. But it really gave us the opportunity to be exposed to a lot of different areas. Like we’d get to go camping. We’d get to ride horses and learn all of these different skills, and so that variety of skill set I think is very applicable to being an astronaut.” - NASA astronaut Loral O’Hara 

Q: What would your advice be for the next generation of Girl Scout astronauts?

A: “My advice would be to find something that you’re passionate about. Ideally something in the STEM fields: Science, Technology, Engineering or Mathematics, and to pursue that thing that you’re interested in. Pursue that passion, whatever it is. And don’t give up on your dreams, and continue to follow them until you arrive where you want to be.” - NASA astronaut Jessica Watkins 

To all the Girl Scouts out there, keep reaching for the stars because the sky is no longer the limit!

NASA Spotlight: Carbon Cycle and Ecosystems Earth Scientist Erika Podest 

Dr. Erika Podest is a scientist with the Carbon Cycle and Ecosystems Group in our Jet Propulsion Laboratory’s Earth Science Division and Visiting Associate Researcher in the Joint Institute for Regional Earth System Science and Engineering (JIFRESSE) at UCLA. Her research entails using satellite images to study Earth’s ecosystems specifically related to wetlands and boreal forests and how they are being affected by climate change. 

Erika took time from studying our home planet to answer questions about her life and career! Get to know our Earth Scientist: 

What inspires/motivates you?

I am inspired by the beauty of nature, its perfection and by the peace it brings me. My motivation is to make a positive impact on our planet by better understanding it and caring for it.

What first sparked your interest in Earth science?

I was born and raised in Panama, which is a country with an exuberant nature. Since I can remember, I was always surrounded by nature because my father was an adventurer who loved the outdoors and always took me with him to go exploring or simply to enjoy a nice relaxing day outside. This led me to develop a deep sense of appreciation, respect, and curiosity for nature, which sparked my interest to learn about it and pursue a career in Earth Science.

What got you interested in the study of Earth from space?

Early in my college years I was training for my private pilot’s license and during my solo flights I would take pictures of features on the surface from the plane. I was always amazed at the details the pictures showed of the landscape that were not obvious from the ground. This was the first step towards discovering that there was a field for studying Earth from above, called remote sensing and consequently my Masters and Ph.D. were focused in this field.

What technology, discovery, or policy do you think has the most potential to decrease humans’ environmental impact (e.g. wind turbines, carbon taxes, clean meat)?

I don’t think it is a matter of any one technology, discovery or policy. It is a combination of everything. Having an impact on climate change involves every level and direction, from the bottom up at the individual, grassroots and community level to the top down at the policy level. As individuals, I think it is important to educate ourselves about climate change (I suggest climate.nasa.gov). We all have the power to make a positive change by speaking up and making informed decisions about our consumptive habits.

What’s a fact about the role of wetlands and boreal forests in the global ecosystem that you think would surprise people?

Wetlands provide a vital role in carbon storage. Even though they cover about 5-8% of the Earth’s land surface, studies indicate that they contain a disproportionate amount of our planet’s total soil carbon, about 20-30%. In addition, they are like the arteries and veins of the landscape, acting as water sources and purifiers and helping in flood control. They also protect our shores and harbor large amounts of biodiversity.

Boreal forests are found in the uppermost northern hemisphere (Alaska, most of Canada, Russia, Scandinavia and northern Asia) and account for about 30% of the world’s forest cover. These forests lock up enormous amounts of carbon and help slow the increasing buildup of carbon dioxide in our atmosphere. In their peak growth phase during the northern spring and summer, the worldwide levels of carbon dioxide fall and the worldwide levels of oxygen rise. 

Can you describe a typical day on a research trip?

It depends on the research trip. For example, one of my more recent ones was to the Peruvian Amazon where we went upriver on a boat for three weeks on a major tributary of the Amazon River called the Ucuyali River. I was with a team of eight researchers and we were studying the wetland ecosystems of the Pacaya-Samiria Natural Reserve, which entailed making vegetation measurements and assessing inundation extent to validate our scientific findings from satellite observations. We camped for most of the trip and a typical day entailed waking up at around 5:00 am with a symphony of sounds that emerged from the forest, including monkeys. We had breakfast and set off from base camp into the forest (~1 hour walk) to work an 8-9 hour day with a short lunch break (we had packed lunches) at noon. At the end of the day I’d be drenched in sweat, sunscreen, insect repellent, and dust and I’d bathe with water from the river, which was as brown as a milk chocolate bar. It was the most refreshing and cleansing feeling! The day would close with dinner followed with a discussion of the measurements to be collected the following day. Lights were out by 7:30 pm (which seemed like midnight) and I’d re-emerge myself into my tent in the dark tropical night surrounded by the sounds of the forest, until the next morning.

What are some of the most important lessons you’ve learned in life?

That it is important to be patient, humble and thankful.

Do you have any secret skills, talents, or hobbies?

Great question! I do not have any secrete skills or talents but I do have a couple of hobbies. I play the piano, though I am still a novice. I love windsurfing. It is an amazing feeling to skim over the water at fast speeds (I’m also an adrenaline junkie). Finally, I am fascinated by magic card tricks and whenever I have some free time I like to learn a new trick.

What do you enjoy the most about your job?

I enjoy constantly learning about our natural world and how it works. I also really enjoy communicating my work to students and to the general public. I find it especially rewarding when I can educate people and motivate students to consider careers in science.

Erika, thank you for your time and everything you do to keep our home planet safe!

Today is Equal Pay Day. On average, a woman in the U.S. has to work until today — March 25th — to earn what a white man was paid in 2024. 🪙🙅🏽‍♀️💵

And the gender wage gap is even worse for women of color. Compared to white men:

💲 Latina and Native women earn 58 cents

💲 Black women earn 66 cents

💲 White women earn 80 cents

💲 Asian American women earn 94 cents

If you care about wages and pay inequality, the politicians WE elect can create policies to address it. Make sure you are registered to vote right now at WhenWeAllVote.org/check.

When will we stop treating women's reactions to offenses as worse than the offenses themselves?

To mark the end of Women’s History Month, here are 10 women who changed the world and inspired thousands.

Florence Nightingale, 1820 - 1910

Florence Nightingale trained nurses and organized medical care for soldiers during the Crimean War (1853 to 1856) between the Ottoman and Russian Empires. Considered to be the founder of modern nursing.

Clara Barton, 1821 - 1912

Clara Barton served as a nurse during the American Civil War, providing self taught nursing care, as she did not possess any formal medical training. Went on to found the American Red Cross in 1881.

Marie Curie, 1867 - 1934

Marie Curie was a French-Polish physicist and chemist who conducted pioneering research in the field of radioactivity, along with her husband Pierre Curie and Henri Becquerel. First woman to win a Nobel prize, and only person to win a Nobel prize to two scientific fields (physics and chemistry). Also first woman to serve as a professor at the University of Paris in France.

Rosa Parks, 1913 - 2005

Rosa Parks was an activist during the American Civil Rights Movement. In 1955, she was arrested for refusing to vacate her bus seat for a white man in Montgomery, Alabama. This incident helped inspire the Montgomery Bus Boycott that led to the desegregation of public buses in the State of Alabama in 1956.

Amelia Earhart, 1897 - disappeared 1937, declared dead 1939

Amelia Earhart was a pilot who was the first female aviator to fly solo over the Atlantic Ocean. Instrumental in the formation of the Ninety-Nines, a female pilots organization. Disappeared while flying over the Pacific Ocean near Howland Island in 1937, along with her navigator Fred Noonan.

Eleanor Roosevelt, 1884 - 1962

Eleanor Roosevelt was the First Lady of the United States as wife of President Franklin Delano Roosevelt from 1933 to 1945. Advocated for expanded roles of women in the work place and supported the civil rights of Black and Asian Americans. Served as the first chair of the United Nations Commission on Human Rights and oversaw the creation of the Universal Declaration of Human Rights in 1948.

Aretha Franklin, 1942 - 2018

Aretha Franklin was a singer and songwriter best known for being the “Queen of Soul”. She started out singing in her church choir as a child, and signed with Columbia Records in 1960 and Atlantic Records in 1966. Sang hit songs that include “Respect”, “Never Loved a Man (The Way I Love You)”, “Think”, and “I Say a Little Prayer”.

Harriet Tubman, 1822 - 1913

Harriet Tubman was an abolitionist and escaped slave who led approximately 70 slaves to freedom along the Underground Railroad. Served as a Union spy during the civil war and supported women’s suffrage after the war. Serves as a symbol for freedom and courage.

Katherine Johnson, 1918 - 2020

Katherine Johnson was a mathematician whose calculations in orbital mechanics working at NASA were critical in the success in the first American crewed spaceflights. Pioneered the use of computers to perform the tasks. One of the first few black women to work as a NASA scientist. Awarded the Medal of Freedom by President Barack Obama in 2015.

Susan B. Anthony, 1820 - 1906

Susan B. Anthony was a social reformer and women’s rights activist who was pivotal in the Women’s Suffrage Movement. Co-founded the National Woman Suffrage Association with Elizabeth Cady Staton in 1869, which merged with the American Woman Suffrage Association in 1890 to form the National American Women Suffrage Association, in which Anthony served as a dominant figure. Presented to Congress an amendment that allowed women to vote. The 19th amendment, nicknamed the “Susan B. Anthony Amendment” was passed in 1920, allowing women the right to vote.
