You know what’s bullshit? When a man unifies several existing physics concepts in a revolutionary way (James Maxwell), he gets an important set of equations named after him. When a woman unifies several existing physics concepts in a revolutionary way (Émilie du Châtelet), if she’s ever mentioned at all, they say shit like that “she elucidated the concept of energy conservation.” She was the first to suggest conservation of total energy, one of the most foundational concepts in the entire field!!!!!

NASA Spotlight: Earth Climate Scientist Dr. Yolanda Shea
Dr. Yolanda Shea is a climate scientist at NASA's Langley Research Center. She’s the project scientist for the CLARREO Pathfinder (CPF) mission, which is an instrument that will launch to the International Space Station to measure sunlight reflected from Earth. It will help us understand how much heat is being trapped by our planet’s atmosphere. Her mission is designed to help us get a clearer picture than we currently have of the Earth’s system and how it is changing
Yolanda took time from studying our home planet to answer questions about her life and career! Get to know this Earth scientist:
What inspired you to study climate science?
Starting in early middle school I became interested in the explanations behind the weather maps and satellite images shown on TV. I liked how the meteorologists talked about the temperature, moisture, and winds at different heights in the atmosphere, and then put that together to form the story of our weather forecasts. This made me want to learn more about Earth science, so I went to college to explore this interest more.
The summer after my junior year of college, I had an internship during which my first assignment was to work with a program that estimated ocean currents from satellite measurements. I was fascinated in the fact that scientists had discovered a way to map ocean currents from space!
Although I had learned about Earth remote sensing in my classes, this was my first taste of working with, and understanding the details of, how we could learn more about different aspects of the physical world from satellite measurements.
This led to my learning about other ways we can learn about Earth from space, and that includes rigorous climate monitoring, which is the area I work in now.
Tumblr media
What does a day in your life look like?
Before I start my workday, I like to take a few minutes to eat breakfast, knit (I’m loving sock knitting right now!), and listen to a podcast or audio book. Each workday really looks different for me, but regardless, most days are a combination of quieter moments that I can use for individual work and more interactive times when I’m interfacing with colleagues and talking about project or science issues. Both types of work are fun in different ways, but I’m glad I have a mixture because all researchers need that combination of deep thinking to wrap our minds around complex problems and also time to tackle those problems with others and work on solving them together.
When do you feel most connected to Earth?
I’ve always loved sunsets. I find them peaceful and beautiful, and I love how each one is unique. They are also a beautiful reminder of the versatility of reflected light, which I study. Sitting for a moment to appreciate the beauty and calm I feel during a sunset helps me feel connected to Earth.
Tumblr media
What will your mission – CLARREO Pathfinder – tell us about Earth?
CLARREO Pathfinder (CPF) includes an instrument that will take measurements from the International Space Station and will measure reflected sunlight from Earth. One of its goals is to demonstrate that it can take measurements with high enough accuracy so that, if we have such measurements over long periods of time, like several decades, we could detect changes in Earth’s climate system. The CPF instrument will do this with higher accuracy than previous satellite instruments we’ve designed, and these measurements can be used to improve the accuracy of other satellite instruments.
How, if at all, has your worldview changed as a result of your work in climate science?
The longer I work in climate science and learn from the data about how humans have impacted our planet, the more I appreciate the fragility of our one and only home, and the more I want to take care of it.
Tumblr media
What advice would you give your younger self?
It’s ok to not have everything figured out at every step of your career journey. Work hard, do your best, and enjoy the journey as it unfolds. You’ll inevitably have some surprises along the way, and regardless of whether they are welcome or not, you’re guaranteed to learn something.
Do you have a favorite metaphor or analogy that you use to describe what you do, and its impact, to those outside of the scientific community?
I see jigsaw puzzles as a good illustration of how different members of a science community play a diverse set of roles to work through different problems. Each member is often working on their own image within the greater puzzle, and although it might take them years of work to see their part of the picture come together, each image in the greater puzzle is essential to completing the whole thing. During my career, I’ll work on a section of the puzzle, and I hope to connect my section to others nearby, but we may not finish the whole puzzle. That’s ok, however, because we’ll hand over the work that we’ve accomplished to the next generation of scientists, and they will keep working to bring the picture to light. This is how I try to think about my role in climate science – I hope to contribute to the field in some way; the best thing about what I have done and what I will do, is that someone else will be able to build on my work and keep helping humanity come to a better understanding of our Earth system.
What is a course that you think should be part of required school curriculum?
Time and project management skills – I think students tend to learn these skills more organically from their parents and teachers, but in my experience I stumbled along and learned these skills through trial and error. To successfully balance all the different projects that I support now, I have to be organized and disciplined, and I need to have clear plans mapped out, so I have some idea of what’s coming and where my attention needs to be focused.
Another course not specifically related to my field is personal financial management. I was interested in personal finance, and that helped me to seek out information (mainly through various blogs) about how to be responsible with my home finances. There is a lot of information out there, but making sure that students have a solid foundation and know what questions to ask early on will set them to for success (and hopefully fewer mistakes) later on.
Tumblr media
What’s the most unexpected time or place that your expertise in climate science and/or algorithms came in handy?
I think an interesting part of being an atmospheric scientist and a known sky-watcher is that I get to notice beautiful moments in the sky. I remember being on a trip with friends and I looked up (as I usually do), and I was gifted with a gorgeous sundog and halo arc. It was such a beautiful moment, and because I noticed it, my friends got to enjoy it too.
Tumblr media
Can you share a photo or image from a memorable NASA project you’ve worked on, and tell us a little bit about why the project stood out to you?
I absolutely loved being on the PBS Kids TV Show, SciGirls for their episode SkyGirls! This featured a NASA program called Students’ Clouds Observations On-Line (S’COOL). It was a citizen science program where students from around the globe could take observations of clouds from the ground that coincided with satellite overpasses, and the intention was to help scientists validate (or check) the accuracy of the code they use to detect clouds from satellite measurements. I grew up watching educational programming from PBS, so it was an honor to be a science mentor on a TV show that I knew would reach children across the nation who might be interested in different STEM fields. In this photo, the three young women I worked with on the show and I are talking about the different types of clouds.

This High Schooler Invented Color-Changing Sutures to Detect Infection
By Theresa Machemer
Dasia Taylor has juiced about three dozen beets in the last 18 months. The root vegetables, she’s found, provide the perfect dye for her invention: suture thread that changes color, from bright red to dark purple, when a surgical wound becomes infected.
The 17-year-old student at Iowa City West High School in Iowa City, Iowa, began working on the project in October 2019, after her chemistry teacher shared information about state-wide science fairs with the class. As she developed her sutures, she nabbed awards at several regional science fairs, before advancing to the national stage. This January, Taylor was named one of 40 finalists in the Regeneron Science Talent Search, the country’s oldest and most prestigious science and math competition for high school seniors.
“I've done a lot of racial equity work in my community, I've been a guest speaker at several conferences,” says Taylor. “So when I was presented with this opportunity to do research, I couldn't help but go at it with an equity lens.”
Before the Covid-19 pandemic, Taylor spent most of her time after school in the Black History Game Show, a club she’s been a member of since eighth grade, and attending weekly school board and district meetings to advocate for an anti-racist curriculum. For the four months leading up to her first regional science fair in February 2020, Taylor committed Friday afternoons to research under the guidance of her chemistry teacher, Carolyn Walling.
Healthy human skin is naturally acidic, with a pH around five. But when a wound becomes infected, its pH goes up to about nine. Changes in pH can be detected without electronics; many fruits and vegetables are natural indicators that change color at different pH levels.
“I found that beets changed color at the perfect pH point,” says Taylor. Bright red beet juice turns dark purple at a pH of nine. “That's perfect for an infected wound. And so, I was like, ‘Oh, okay. So beets is where it's at.’”
Next, Taylor had to find a suture thread that would hold onto the dye. She tested ten different materials, including standard suture thread, for how well they picked up and held the dye, whether the dye changed color when its pH changed, and how their thickness compared to standard suture thread. After her school transitioned to remote learning, she could spend four or five hours in the lab on an asynchronous lesson day, running experiments.
A cotton-polyester blend checked all the boxes. After five minutes under an infection-like pH, the cotton-polyester thread changes from bright red to dark purple. After three days, the purple fades to light gray.
Working with an eye on equity in global health, she hopes that the color-changing sutures will someday help patients detect surgical site infections as early as possible so that they can seek medical care when it has the most impact. Taylor plans to patent her invention. In the meantime, she’s waiting for her final college admissions results.

if you ever feel like you're not "smart enough" for STEM or didn't do that great in school, i just wanna let you know that i failed algebra 2 THREE TIMES and dropped my high school physics class the FIRST WEEK...
and NASA chose me to student research with them.
so what i'm trying to say is that STEM is for EVERYONE. if school wasn't the easiest for you and you're not the strongest in math, don't let that stop you from pursuing STEM. working hard for goals makes you a great scientist.
screw that stereotype that all STEM majors are geniuses who were building robots and knew how to work a microscope at 3 years old.

[The Love Hypothesis, by: Ali Hazelwood, aesthetic]
"carry yourself with the confidence of a mediocre white man."
"I wish you could see yourself the way I see you."
"You can fall in love: someone will catch you."
"You kiss him and next thing you know he's saving your ass and he's buying you scones and calling you a smart-ass in a weirdly affectionate tone"
"She would have loved to run to the edge of campus and scream into the void until modern civilization collapsed, but that wasn’t exactly a pressing matter."
"God, she had forced a married man, a father, to kiss her. Now people thought that he was having an affair. His wife was probably crying into her pillow. His kids would grow up with horrible daddy issues and become serial killers."
"his calm acceptance of her anxiety relaxed her"

Curious about how to send research to the International Space Station or how to get involved with NASA missions as a college student? Ask our experts!
Through our Student Payload Opportunity with Citizen Science, or SPOCS, we’re funding five college teams to build experiments for the International Space Station. The students are currently building their experiments focusing on bacteria resistance or sustainability research. Soon, these experiments will head to space on a SpaceX cargo launch! University of Idaho SPOCS team lead Hannah Johnson and NASA STEM on Station activity manager Becky Kamas will be taking your questions in an Answer Time session on Thurs., June 3, from 12-1 p.m. EDT here on our Tumblr! Make sure to ask your question now by visiting http://nasa.tumblr.com/ask. Hannah Johnson recently graduated from the University of Idaho with a Bachelor of Science in Chemical Engineering. She is the team lead for the university’s SPOCS team, Vandal Voyagers I, designing an experiment to test bacteria-resistant polymers in microgravity. Becky Kamas is the activity manager for STEM on Station at our Johnson Space Center in Houston. She helps connect students and educators to the International Space Station through a variety of opportunities, similar to the ones that sparked her interest in working for NASA when she was a high school student. Student Payload Opportunity with Citizen Science Fun Facts:
Our scientists and engineers work with SPOCS students as mentors, and mission managers from Nanoracks help them prepare their experiments for operation aboard the space station.
The Vandal Voyagers I team has nine student members, six of whom just graduated from the Department of Chemical and Biological Engineering. Designing the experiment served as a senior capstone project.
The experiment tests polymer coatings on an aluminum 6061 substrate used for handles on the space station. These handles are used every day by astronauts to move throughout the space station and to hold themselves in place with their feet while they work.
The University of Idaho’s SPOCS project website includes regular project updates showing the process they followed while designing and testing the experiment.
