Where the Wild Things Are: Wildlife Management with Johnson’s Matt Strausser

NASA - Breaking News - Mon, 08/18/2025 - 5:00pm

If you asked someone what they expected to see during a visit to NASA’s Johnson Space Center, they would probably list things like astronauts, engineers, and maybe a spacecraft or two. It might be a surprise to learn you can also spy hundreds of species of animals – from geckos and snakes to white-tailed deer and red-tailed hawks.

Ensuring those species and Johnson’s workforce can safely coexist is the main job of Matt Strausser, Johnson’s senior biologist for wildlife management. Strausser works to reduce the negative impacts animals can have on Johnson’s operations as well as the negative impact humans might have on native wildlife and their habitats.

Strausser joined NASA in 2012, fresh out of graduate school, when he was hired on a six-month contract to write Johnson’s first Wildlife Management Plan. “My contract was extended a couple of times until I became a regular part of the facilities service contract, which is where I still am today,” he said.

Strausser remembers being interested in natural resources from a young age. “I spent a lot of my childhood poring through copies of National Geographic, hiking, and camping,” he said. When it was time for college, Strausser decided to study biology and natural resource management. He spent his summers in jobs or internships that mostly involved endangered wildlife species, including Attwater’s prairie chickens, which are bred at Johnson through a partnership with the Houston Zoo. Strausser noted that he conducted research across the country while he was a student, and even studied fish for a short time in the South Pacific.

“After all of those adventures in faraway places, I find it ironic that I ended up about 20 miles from where I grew up,” he said. “Once I got onsite, it did not take me long to find that this property has great remnant native plant communities, a fascinating land use history, and some unique natural resource challenges that come from the work done here. Those factors really drew me in and helped motivate me to build a career at Johnson.”

Matthew Strausser received a Silver Snoopy Award through NASA’s Space Flight Awareness Program in 2018, in recognition of his efforts to prevent and mitigate ant-inflicted damage to critical infrastructure electrical systems. From left: NASA astronaut Reid Weissman, Strausser, Strausser’s wife Kayla, NASA Acting Associate Administrator Vanessa Wyche. NASA

Strausser’s work involves a variety of activities. First, he gathers data about Johnson’s wildlife populations and their habitats. “I use population counts, conflict records, satellite and aerial imagery, nest surveys, outside reports, and even historical data to get an understanding of what’s on the landscape and what problems we have to tackle,” he said.

With that information, Strausser works to engage project and facility managers and provide recommendations on how to prevent or reduce the impact of wildlife problems onsite. Strausser works with Johnson’s facilities maintenance group to modify buildings to keep animals on the outside, and he gets support from the Johnson veterinarian on animal health issues. He also works closely with Johnson’s pest control and groundskeeping contracts, as their work is often adjacent to wildlife management.

He supports the safety team, as well. “Our security contractors are a great resource for reporting wildlife issues as well as helping address them,” Strausser said, adding that some of Johnson’s safety groups “have been really helpful at getting the word out about how to stay safe around our wildlife” in coordination with the center’s internal communications team.  His team also responds to wildlife conflict calls, which often involve capturing and relocating animals that have wandered into areas where they pose a risk to people or operations.

Additionally, Strausser runs the facilities contract’s small unmanned aircraft system, which uses drones to conduct facility inspections, support hurricane response, and survey on-site wildlife.

The nature of his work has instilled in Strausser an appreciation for teamwork and collaboration among colleagues with distinct experiences. Each of the projects he works on involves team members from different organizations and contracts, and most of them do not have a background in biology. “Building a wildlife and natural resource program from the ground up and bringing all of these once-disconnected and diverse professionals together to effectively address problems – that is the achievement I take the most pride in,” he said.

Strausser observed that accomplishing the goals of the agency’s Artemis campaign will require a tremendous amount of specialized support infrastructure, and that developing and running that infrastructure will require a wide variety of professionals. “It is going to require students and specialists with all different types of backgrounds, passions, and talents.”

Overall, Strausser said he has a very dynamic job. “Wildlife issues tend to be very seasonal, so throughout the year, the types of issues I am addressing change,” he said. “On top of that, there are always new projects, problems, and questions out there that keep the work fresh and challenging.” He has learned the value of being open to new challenges and learning new skills. “Being adaptable can be just as important as mastery in a specific field,” he said.

NASA Sets Coverage for SpaceX 33rd Station Resupply Launch, Arrival

NASA - Breaking News - Mon, 08/18/2025 - 4:50pm
The SpaceX Falcon 9 rocket carrying the Dragon spacecraft lifts off from Launch Complex 39A at NASA’s Kennedy Space Center in Florida on April 21, 2025, on the company’s 32nd commercial resupply services mission for the agency to the International Space Station. Liftoff was at 4:15 a.m. EDT. SpaceX

NASA and SpaceX are targeting 2:45 a.m. EDT, Sunday, Aug. 24, for the next launch to deliver science investigations, supplies, and equipment to the International Space Station. This is the 33rd SpaceX commercial resupply services mission to the orbital laboratory for NASA.

Filled with more than 5,000 pounds of supplies, a SpaceX Dragon spacecraft on a Falcon 9 rocket will lift off from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida. Dragon will dock autonomously about 7:30 a.m. on Monday, Aug. 25, to the forward port of the space station’s Harmony module.

Watch agency launch and arrival coverage on NASA+, Netflix, Amazon Prime, and more. Learn how to watch NASA content through a variety of platforms, including social media.

In addition to food, supplies, and equipment for the crew, Dragon will deliver several experiments, including bone-forming stem cells for studying bone loss prevention and materials to 3D print medical implants that could advance treatments for nerve damage on Earth. Dragon also will deliver bioprinted liver tissue to study blood vessel development in microgravity and supplies to 3D print metal cubes in space. Research conducted aboard the space station advances future space exploration – including Artemis missions to the Moon and astronaut missions Mars – and provides multiple benefits to humanity.

In addition, Dragon will perform a reboost demonstration of station to maintain its current altitude. The hardware, located in the trunk of Dragon, contains an independent propellant system separate from the spacecraft to fuel two Draco engines using existing hardware and propellant system design. The boost kit will demonstrate the capability to help sustain the orbiting lab’s altitude starting in September with a series of burns planned periodically throughout the fall of 2025. During NASA’s SpaceX 31st commercial resupply services mission, the Dragon spacecraft performed its first demonstration of these capabilities on Nov. 8, 2024.

The Dragon spacecraft is scheduled to remain at the space station until December when it will depart and return to Earth with research and cargo, splashing down in the Pacific Ocean off the coast of California.

Station Nation: Meet Tess Caswell, Extravehicular Activity Flight Controller and Lead Capsule Communicator 

NASA News - Mon, 08/18/2025 - 3:38pm

Tess Caswell supports the International Space Station from NASA’s Johnson Space Center in Houston as a capsule communicator, or capcom, and helps plan and train for future spacewalks with the Extravehicular Activity (EVA) team in the Flight Operations Directorate. 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.

Read on to learn more about Tess!

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!

Tess Caswell

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.

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! 

Tess Caswell learns to fly the International Space Station Remote Manipulator System, or Canadarm2, in Canada as part of capcom training. Tess Caswell

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.

Tess Caswell

Extravehicular Activity Flight Controller and Lead Capsule Communicator 

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?

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.

Station Nation: Meet Tess Caswell, Extravehicular Activity Flight Controller and Lead Capsule Communicator 

NASA - Breaking News - Mon, 08/18/2025 - 3:38pm

Tess Caswell supports the International Space Station from NASA’s Johnson Space Center in Houston as a capsule communicator, or capcom, and helps plan and train for future spacewalks with the Extravehicular Activity (EVA) team in the Flight Operations Directorate. 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.

Read on to learn more about Tess!

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!

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.

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.

New Lightsail Material Pushes Interstellar Probe Dream Closer

Universe Today - Mon, 08/18/2025 - 3:34pm

Any material used as a light sail is bound by very restrictive physical requirements. It has to be extremely light , can’t melt from the energy applied to it, and must bend, but not break, from that pressure. Various research groups around the world have been working on materials they believe will meet those requirements, and a new paper from researchers at the University of Pennsylvania describes experimental testing of what they believe to be the most functional light sail material yet developed.
