There's an issue on the International Space Station (ISS) that is becoming a growing concern for both the Russian and American space programs.
The ISS is leaking, and the matter is rightfully getting attention from media around the world. The reporters looking for answers are connecting with Florida Tech's Don Platt to explain what exactly is happening and what it means for the future of this $100 billion facility.
Dr. Platt's work has involved developing, testing and flying different types of avionics, communications and rocket propulsion systems. He teaches about space systems. The problem exemplifies how NASA is contending with aging but critical space infrastructure: The orbiting laboratory, with a living area larger than a six-bedroom house, is the agency's only way to learn about health impacts to astronauts, develop or test life support systems for future missions, and advance a plethora of space technologies. NASA wants to keep it running until 2030 — but doing so will require constant surveillance and, literally, patching. "It's an old station, and it has done some amazing things," Don Platt, an associate professor of space systems at Florida Tech, told Mashable. Mashable, Nov. 19 Local television and national networks like NPR were also seeking Platt's expert insights.
NASA and Russian space officials are at odds over the significance of a long-standing air leak aboard the International Space Station. The leak, originating from a Russian module, has reportedly persisted for about five years. Don Platt, an associate professor at the Florida Institute of Technology, explained the potential risks. “There’s definitely concerns about this leak and the potential for it to get worse over time,” Platt said. While NASA views the issue as a serious safety concern, Moscow insists the situation is under control and the module is safe. “NASA is quite concerned about it, and the Russians are more or less saying, ‘We have it under control. Don’t worry about it,’” Platt said. The affected module is one of the oldest on the station, having been operational for more than 20 years. “One of the Russian modules on the space station, one of the oldest, is starting to lose some of the air that astronauts need to breathe,” he said.

Astronauts Butch Wilmore and Suni Williams '95 M.S. took the trip of a lifetime in June, traveling to the International Space Station (ISS) on Boeing's Starliner spacecraft.
Not long after their arrival to the ISS, however, the spacecraft began having mechanical issues. Since then, the pair have been left stranded in space with no return flight booked to come home.
As the scientific world, public and international media watch, experts like Don Platt from Florida Tech are supporting ongoing media coverage until the two astronauts return to Earth.
To return Starliner to Earth, the thrusters need to fire correctly at the right time to get the crew safely out of orbit. "Clearly, you need to have thrusters to be able to position your spacecraft, to move away from the space station, to get into the position to safely reenter the Earth's atmosphere," said Don Platt, associate professor of space systems at Florida Tech. "They claim just doing a rocket burn, they can probably make it home, but they don't know where'd they land," said Platt. The problem lies with the propulsion system inside the service module. "It sounds as if they've experienced a different amount of heating than expected with some of these thrusters, and had some affected things like valves that control the flow of propellant to the thrusters. So sometimes those valves will leak or not open all the way based on the amount of heat they are experiencing," said Platt. Platt explained that the valves for these thrusters are comparable to fuel injectors in a car. They simply open and close to feed the propellant into the combustion chamber − the end result being thrust (power). Part of the challenge for Boeing teams is that they can't exactly replicate what the spacecraft is experiencing in space. Platt said that heat is not just created from the thruster itself, but from the Sun. August 11 - Florida Today Don Platt, the director of Florida Tech’s Spaceport Education Center in Titusville and an associate professor of space systems, explained that Boeing is currently trying to figure out what went wrong with Starliner and to see if there is still a chance to use the thrusters. "There's probably very little they can do to fix them at this point," Platt said. "What they can do is they can look at what thrusters are working properly, and how can we then use those thrusters to efficiently get the vehicle back into the atmosphere and then to the surface of the Earth." While Starliner has been having extensive issues and now Boeing has some tough decisions to make about what's next, Platt said we need to remember that this was a test mission. "I think that we've had a lot of success in space over the last decade or so, and we've probably gotten used to things going perfectly," Platt said. "Although space is not that easy, and we can see problems, problems do pop up from time to time. Even back in the days of the shuttle program, there used to be issues with the orbiter, even on orbit, and they'd have to think about, 'can we keep flying this mission, or do we need to return to the Earth?'"

Associate professor of chemical engineering Toufiq Reza has spent years researching sustainable waste conversion techniques on Earth. When Florida Tech offered him a sabbatical, he took the chance to learn what that conversion process looks like in outer space while further strengthening the university’s already deep ties to NASA.
In Fall 2023, Reza became the first professor to leverage school funding to spend a semester at NASA’s Kennedy Space Center. He worked with Annie Meier, who leads a team developing ways to convert astronaut-generated trash into fuel during missions, known as in-situ resource utilization (ISRU).
“I wanted to do something different that I haven’t done. I have been doing research in my field; I know who the players are,” Reza said.” I could have easily gone to a research lab at another university and continued my research. But I wanted to learn something new.” His sabbatical prompted a new partnership between NASA Kennedy and Florida Tech.
This summer, they signed an annex to their existing Space Act Agreement which will allow Kennedy Space Center (KSC) and the university to conduct joint research regarding logistical waste treatment and ISRU.
“At NASA, we want researchers who are doing something that could help us, that could be synergistic, and to not reinvent the wheel,” said Jose Nuñez, university partnerships and small sat capabilities manager at NASA Kennedy. “The goal is to find professors who can benefit the agency in an area that needs more research.”
As part of the agreement, KSC will share raw materials, waste simulant samples and information such as gas composition data with Florida Tech. In return, the university will analyze and share findings, such as what useful products can be taken from trash-to-gas waste for use as plant nutrients, and evaluate value-added applications.
“I will encourage students to work on some of their technologies, test them in our lab and vice versa. This is a massive thing,” Reza said. “We can learn from each other to help each other.” Already, Reza’s students have visited Meier’s lab, and Meier and her KSC team came to Florida Tech to present her research and visit the university’s research facilities.
Meier’s goals are similar to Reza’s: Both researchers want to find sustainable ways to convert trash and waste into energy, materials and chemicals. However, the methods aren’t completely transferrable between the two different environments of Earth and space. On Earth, Reza explained, waste can be burned or stored in a landfill. Neither of those options are viable in space.
“You cannot dig up the moon soil and start burying. There is no oxygen or air to actually burn it…there is no water,” Reza explained. Currently, astronaut waste, such as food packaging, clothing, hygiene items and uneaten food, is launched back towards Earth and incinerates on the way there. However, Meier is working to advance waste mitigation technology, which Reza got to see up close. One of her projects, the Orbital Syngas/Commodity Augmentation Reactor (OSCAR), mixes oxygen, heat and trash in a reactor, which burns the trash and collects the gas it creates.
Over the course of the semester, Reza assisted in KSC’s Applied Chemistry Lab, where Meier’s research took place. He offered both expertise and extra hands, from helping measure samples to reading through literature. He also took note of innovative technology for potential new research ideas, such as potentially developing a way of protecting metal coatings in space using the tools he learned.
Meier’s waste conversion technology is built for a space environment, but Reza said it is unlikely that her complete systems could be used for waste conversion on Earth. Just as water and oxygen are limited resources in space but are plentiful on Earth, vacuums are plentiful resources in space but are expensive to create back home. However, that doesn’t stop the researchers from seeking inspiration through the new partnership.
“We can learn from them and then take a part of their technology and integrate it with ours to make our technology more sustainable and vice versa,” Reza said. “They can improve their technology by utilizing part of our technology as well. As Meier said, “I wanted to learn on the terrestrial side how we can infuse some of our technology, and he wanted to learn from us to grow into the space sector, so it was a really cool match.”
