Two Chinese astronauts spent more than six hours outside the Tiangong space station on Friday (Aug. 15), installing a debris shield on the third spacewalk of the Shenzhou 20 mission.

Tess Caswell supports the International Space Station from NASA’s Johnson Space Center in Houston as a capsule communicator, or capcom, as well as through the Extravehicular Activity Office. She is currently on rotation as the Artemis lead capcom, helping to develop training and processes for the Artemis campaign by leveraging her experience supporting the space station.

She helps ensure that astronauts aboard the spacecraft receive the right information at the right time. This role involves a range of activities, from learning the language of the spacecraft and its onboard operations to participating in simulations to relay critical information to the crew, especially during dynamic operations or when things go wrong.

Where are you from? 

Soldotna, Alaska. 

How would you describe your job to family or friends that may not be familiar with NASA? 

Capcoms are the people who speak to the astronauts on behalf of Mission Control, and I am the lead for the team of capcoms who will support missions to the Moon as part of NASA’s Artemis campaign.  

What advice would you give to young individuals aspiring to work in the space industry or at NASA? 

Remember that space travel is more than just engineers and scientists. It takes all kinds of people to support astronauts in space, including medicine, food science, communications, photography – you name it!

Extravehicular Activity Flight Controller and Lead Capsule Communicator 

I like to encourage young people to think about what part of space travel inspires them. We live in an era where there are many companies leveraging space for different purposes, including tourism, settlement, profit, and exploration. It’s important to think about what aspect of space travel interests you – or use things like internships to figure it out! 

If you’re excited about space but don’t want to be an engineer, there are still jobs for you. 

How long have you been working for NASA? 

Eight years, plus a few internships. 

What was your path to NASA? 

Internships and student projects were my path to NASA. As an undergraduate, I worked in a student rocket lab, which gave me firsthand experience building and testing hardware. During the summers, I participated in internships to explore various careers and NASA centers. My final internship led directly to my first job after college as an Environmental and Thermal Operating Systems (ETHOS) flight controller in mission control for the space station. 

I left NASA for a while to pursue an advanced degree in planetary geology and spent two years working at Blue Origin as the lead flight controller for the New Shepard capsule. Ultimately, though, I am motivated by exploration and chose to return to NASA where that is our focus. I landed in the Extravehicular Activity Office (EVA) within the Flight Operations Directorate after returning from Blue Origin.

Is there a space figure you’ve looked up to or someone that inspires you?  

It’s hard to name a specific figure who inspires me. Instead, it’s the caliber of people overall who work in flight operations at Johnson Space Center. Not just the astronauts, but the folks in mission control, in the backrooms supporting the control center, and on the training teams for astronauts and flight controllers. Every single person demonstrates excellence every day. It inspires me to bring my best self to the table in each and every project. 

What is your favorite NASA memory or the most meaningful project you’ve worked on during your time with NASA? 

That is a hard one!  

My current favorite is probably the day I certified as a capcom for the space station. The first time talking to the crew is both nerve-wracking and exciting. You know the entire space station community stops and listens when you are speaking, but it’s incredibly cool to be privileged with speaking to the crew. So, your first few days are a little scary, but awesome. After I’d been declared certified, the crew called down on Space –to Ground to congratulate me. It was a very special moment. I saved a recording of it!

What do you love sharing about station? 

The international collaboration required to design, build, and operate the International Space Station is a constant source of inspiration for me.

When I give folks tours of mission control, I like to point out the photo of the U.S.-built Unity node and the Russian-built Zarya module mated in the shuttle cargo bay. The idea that those two modules were designed and built in different countries, launched in two different vehicles, and connected for the first time in low Earth orbit reminds me of what we can all do when we work together across geopolitical boundaries. The space station brings people together in a common mission that benefits all of us. 

If you could have dinner with any astronaut, past or present, who would it be? 

Sally Ride, definitely. 

Do you have a favorite space-related memory or moment that stands out to you? 

If I had to choose one, I’d say it was the day a person from NASA visited my elementary school in 1995. I remember being completely captivated by his presentation and dying to ask questions when he came by my classroom later. It’s a favorite memory because it poured fuel on the spark of my early childhood interest in space exploration. It wasn’t the thing that initially piqued my interest, but that visit made the dream feel attainable and set me on the course that has me at NASA today. 

What are some of the key projects you have worked on during your time at NASA? What have been your favorite? 

I’ve worked in mission control for the space station as an ETHOS flight controller and, later, as a capcom. I’ve also certified as an EVA task backroom controller and scripted three spacewalks that were performed on the space station. While working in EVA, I also helped design the products and processes that will be used to design moonwalks for Artemis astronauts and how flight control operations will work during dynamic, science-driven spacewalks.  

 Developing an EVA is a huge integration effort, and you get to work with a broad range of perspectives to build a solid plan. Then, the spacewalks themselves were both challenging and rewarding. They didn’t go exactly to plan, but we kept the crew safe and accomplished our primary objectives! 

I’m fortunate to have had so many cool experiences while working at NASA, and I know there will be many more.

What are your hobbies/things you enjoy doing outside of work? 

I like to stay active, including trail running, taekwondo, backpacking, and cross-country skiing (which is a bit hard to train for in Houston). I spend as much time as I can flying my Piper J-3 Cub, trying to make myself a better pilot each time I fly. Finally, I read and write fiction to let my imagination wander. 

Day launch or night launch? 

Night launch! 

Favorite space movie? 

Apollo 13, hands down! 

NASA Worm or Meatball logo? 

Worm – elegant and cool!

In a recent paper, researchers followed the trajectories of 1I/`Oumuamua, 2I/Borisov, and 3I/ATLAS - three installer objects that have entered the Solar System in the past decade - to constrain their possible origin. Through a series of Monte Carlo simulations, they came up with predictions of where they came from and how old they are.

Exoplanets with and without a magnetic field are predicted to form, behave, and evolve very differently. In order to understand the exoplanet population, and to make progress understanding habitability, astronomers need to understand and constrain exoplanets' magnetic fields. Detecting them may best be done from the Moon.

Physicists from the University of Copenhagen have begun using the gigantic magnetic fields of galaxy clusters to observe distant black holes in their search for an elusive particle that has stumped scientists for decades.

We already know a decent amount about how planets form, but moon formation is another process entirely, and one we’re not as familiar with. Scientists think they understand how the most important Moon in our solar system (our own) formed, but its violent birth is not the norm, and can’t explain larger moon systems like the Galilean moons around Jupiter. A new book chapter (which was also released as a pre-print paper) from Yuhito Shibaike and Yann Alibert from the University of Bern discusses the differing ideas surrounding the formation of large moon systems, especially the Galileans, and how we might someday be able to differentiate them.

The Universe's early galaxies were engulfed in halos of high-energy cosmic rays. It's likely because they had tangled and turbulent magnetic fields. These fields accelerate cosmic rays to higher energies.
