For decades, NASA’s testing chambers have been used to simulate the harsh conditions of space, allowing engineers to test the durability of spacecraft and other equipment in a controlled environment. These testing chambers, which can simulate extreme temperature or pressure environments, have played a crucial role in developing new technology for space travel, dating back to the first Apollo space mission.  

Collaborating with NASA on their senior design capstone project, four mechanical and aerospace engineering students, Liam Collins ’25, James Jabbour ’25, Brady McKenna ’25 and Alexandra Vaida ’25, are gaining real-world experience building a mechanical actuator test stand for one of NASA’s testing chambers, Chamber D. Chamber D will be used to test next generation spacesuit gloves and boots at extremely low temperatures. The mechanical actuator will apply force to the test article, allowing engineers and suit designers to analyze the thermal performance of spacesuit gloves and boots as NASA prepares to return to the moon and beyond.  

To gain a better understanding of their design, the team visited NASA’s Johnson Space Center in Houston, Texas, meeting with engineers across various disciplines, including the Chamber D team and industry experts. The team presented their designs and received feedback from various engineers, as well as tours of the Space Environmental Simulation Laboratory and the spacesuit laboratory.  

“There were small vacuum chambers to test spacesuits and big, massive vacuum chambers to test the James Webb telescope, which is hundreds of feet tall. It was incredible to see that. It’s an engineer’s candy shop. Walking in, seeing all this technology they’ve built and are using, it’s mind-blowing,” says Jabbour. 

“It was interesting to see the test sites because we were able to get tours of the facility as well as meet with the engineers. The scale of all their testing was interesting to see in person and it was helpful for our capstone,” says Vaida.  

“We got to meet electrical engineers, controls engineers, thermal engineers and subject matter experts. It was great to hear their perspective on our design, which helped us better understand what we’re doing and how we’re approaching it,” says McKenna.  

In the past, the testing plate in the chamber remained stationary, and test operators would move test articles to touch the plate. What sets Chamber D apart from previous testing is that the contact plate moves toward the test article, rather than requiring test articles to move to the plate. This design choice gives test operators flexibility and gives the students creativity in designing a truly novel system.  

“We’re trying to make it as versatile as we can so different spacesuit companies can use it for whatever test they need,” says Vaida.  

“Our test stand also meets extreme temperature and vacuum requirements that many other chambers cannot, which is unique to our project,” says McKenna.  

The team has been prototyping and testing their mechanical actuator for final presentations and delivery to the Johnson Space Center in May. Final presentations will take place toward the end of the 2025 spring semester. 

“I am very proud of my team for how we handled the adversity. No one ever complained and we all did what we could to help each other, which was great to see,” says Collins. 

“Chamber D will be the Earth’s sandbox for testing technology that will be exposed to the coldest, darkest regions of the moon and beyond,” says Stephen Baker, project manager of NASA’s Systems Test Branch. “No other chamber in the world has the combination of thermal capabilities, size, and convenience. I’m happy with the progress I’ve been seeing on this project.”  

“Liam, James, Brady, and Alexandra made the most of this incredible opportunity to collaborate with NASA on testing next-gen spacesuit components. Their visit to Johnson Space Center truly highlights the value of hands-on, experiential learning,” says Kenneth and Mary Ann Shaw Professor of Practice Alexander Deyhim.

Aiming for the Stars: Aerospace Engineering Student Greg Slodysko Meets NASA Administrator Bill Nelson

Growing up, Greg Slodysko had a deep fascination with space exploration. Games like Kerbal Space Program, which challenged players to design spacecraft for different missions, and movies like October Sky inspired him to create his own model rockets and sparked a keen interest in the world beyond our own.  

“I was always excited to see photos from the Hubble Space Telescope, which has some of the best pictures we’ve ever taken of distant stars and galaxies,” Slodysko says. “I also enjoyed watching documentaries or films about space travel and even went to space camp in high school.”

Now a senior studying aerospace engineering at Syracuse University, Slodysko recently had an experience that further fueled his love for rocketry: a conversation with Bill Nelson, the current NASA Administrator. How exactly did he manage to meet with NASA’s chief officer? The answer lies in an unexpected craving for ice cream. 

Nelson and Congressman Matt Cartwright visited a high school in Slodysko’s hometown of Pittson, Pennsylvania. After the event, the NASA administrator was craving a sweet treat, so they both decided to head over to a nearby ice cream shop. The shop owners were friends with Slodysko’s parents and knew he was studying aerospace engineering at the University, so they invited Slodysko’s dad to the shop while the NASA administrator and the congressman were there. This provided the perfect opportunity for Slodysko to speak with Nelson. 

“When I first got the mention that I had a chance to talk to Bill Nelson, I went for it. I immediately said ‘Yes, get me in!’ These situations are rare and don’t happen often” he says.  

Slodysko couldn’t physically attend the meeting since he was on campus but was thrilled to participate in an impromptu FaceTime call with Nelson. Though he was initially nervous, the conversation was filled with encouragement and support, reigniting Slodysko’s passion for aerospace engineering and potentially paving the way for a future at NASA. 

“They told me I was on the right path, and they were impressed with my work. It was such an inspiring conversation that I’ll never forget” he says.

Slodysko intends to continue exploring his interest in structural design, propulsion, and aerodynamic analysis as he completes his undergraduate degree. He’s also currently completing a computer-based code that produces modular model rocket parts that are 3D printable. He aims to make this code available for free download online so that others can either create their own model rockets by adjusting code variables or work to improve the code created by him.  

Additionally, he plans to enroll in graduate school and hopes to secure an internship with NASA, potentially getting to meet the administrator once again but this time, face-to-face. To Slodysko, this would be an experience that’s truly out of this world. 

“I’m deeply grateful to Congressman Cartwright and Bill Nelson for this once-in-a-lifetime opportunity,” he says. “I’ll never forget this and I’m so excited for what the future holds. This is going to stick with me for a long time.”
