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.”

Manasvi Lingam Bridges Gap Between Introductory and Graduate Astrobiology Education with New Textbook

Astrobiologist Manasvi Lingam, assistant professor of aerospace, physics and space sciences at Florida Tech, authored a new astrobiology textbook to serve as a resource for the rapidly growing multidisciplinary field. “From Stars to Life: A Quantitative Approach to Astrobiology,” published by Cambridge University Press, is primarily geared toward upper-level undergraduate and graduate students studying astrobiology, Lingam says. Co-authored by astrophysicist Amedeo Balbi (University of Rome), the book’s 15 chapters cover topics from the Big Bang theory to planetary habitability to the future of humankind. The book also includes practice problems that involve modern developments like GenerativeAI (e.g., ChatGPT). Lingam explained how he came up with the new textbook and why it can help shape astrobiology programs like Florida Tech’s. What inspired this textbook? Manasvi Lingam: [Florida Tech] was the first university in the whole world to start an undergraduate astrobiology major. We have a strong connection to the field. But it turns out, every time I teach the subject, I don’t have a textbook to use. I have my first book, which is “Life in the Cosmos,” but it’s 1,100 pages. It’s for graduate students. It’s not going to work for them. Every time I was trying to cobble together resources from different places. My co-author has the same problem except that he’s been teaching [astrobiology] for even longer, for 20 years. He doesn’t have a textbook either. There’s this old saying in English: if you want something done right, do it yourself. We decided, well, might as well just try to write it ourselves. That’s how it came to be. How does this textbook bridge the gap between introductory readings and graduate-level material? ML: Right now, there’s pretty much only one class of textbooks for astrobiology, and those are written for freshman- or sophomore-level undergraduates. There’s this emphasis on a broad overview but at an extremely qualitative level and sometimes offering somewhat weak explanations for various specific phenomena, such as, “Why did Mars lose its atmosphere? It just got eroded over time.” These kinds of limitations. Graduate literature is very specialized, oriented towards whatever subfield one is studying in astrobiology. You can have a whole book on the origin of life. You can have a whole book on just Mars. You can have a whole book on Titan and so on. The aforementioned introductory textbooks that exist are very broad, but they don’t really offer a tool to actually get started doing research in the more specialized field. There was this vital need to bridge the gap. That’s what this book is meant to do. How did you decide what content to include and what not to include? ML: This field begins almost with the Big Bang – the start of the universe – which is when the first elements were formed, including elements that are widespread in life like hydrogen. This tale begins almost with the beginning of the universe. It is a tale that is still ongoing and is going to unfold for trillions of years into the future. But, there was so much material to include in principle. We had to be quite selective about what topics to include. There are a number of courses that are taught around the world on this topic. We looked at dozens of them to find the common core within all of them, and then expanded on that core. That’s what constitutes our table of contents. While writing the textbook, how did you grow as a researcher and an educator? ML: There’s this implicit understanding in academia that if you can write something down clearly, and if you can articulate something clearly, that’s when you can really say you understand it. Often you can’t articulate what you need to say coherently and succinctly if it’s something very big. That’s what, of course, astrobiology is. In the process of writing the book as an educator, I think I was really able to see how various domains linked to each other. For instance, modulations of, say, the Earth’s climate that were driven not just by changes on Earth (including life itself!), but also by changes in the sun, by changes in the orbits of other solar system planets, but also phenomena that were taking place hundreds of light years away in the galaxy. You really see that everything is connected – there are hidden links to each other. I think that helped me discover the magic of the universe, so to speak, even more. From a research standpoint, there were some areas that I have not worked in a lot, but by writing this book, I’ve gotten a better understanding of those areas, like, say, Mars, and also certain microbiological and astrophysical aspects as well. I think that has provided new ideas that I hope to explore in the future. What do you want readers to learn throughout the book, and what should they walk away with? ML: What we want to do is build a holistic integrated understanding of different phenomena pertaining to life in the universe, but at a quantitative level, and still retain breadth without sacrificing depth in the process. It won’t necessarily make students ready for research because it’s still primarily an undergrad textbook, but it will give them a comprehensive understanding of how various processes are intertwined with each other. We want people to see the big picture without missing out on the detail, and to appreciate the beauty of life, Earth, the solar system, the Milky Way and the universe. Lingam plans to start teaching from this textbook in Spring 2025. The textbook is available for purchase on Amazon.

Researchers Seek Understanding of Early Life on Earth Following Chilean Expedition

In a discovery that may further our understanding of the early evolution of life on Earth, a research team, including associate professor Andrew Palmer and master’s student Caitlyn Hubric, identified Chile’s deepest and most northern cold seeps—openings in the ocean floor that emit gases and fluids— about 100 miles off the Chilean coast and thousands of feet below the surface. This most terrestrial of discoveries may also yield insights that could benefit future space exploration, Palmer said. Palmer, who runs the astrobiology and chemical ecology lab at Florida Tech, and Hubric, who has studied with him for the last three years, represented the university on Schmidt Ocean Institute’s (SOI) expedition through the Atacama Trench. The trench is a nearly 5-mile-deep oceanic trench in the eastern Pacific Ocean that has remained at the same latitude for the last 150 million years, suggesting an extremely stable and potentially ancient ecosystem. The trench’s seeps, found at a depth of 2,836 meters (9,304 feet), provide chemical energy for deep sea animals living without sunlight, according to SOI. Seeps like this one can help astrobiologists understand how life developed on Earth and how those survival strategies and chemical conditions might sustain life on other planets. Palmer and Hubric were members of the expedition’s microbiology team and were specifically searching for biosignatures. That meant looking out for novel microbes and chemical signatures, like proteins or carbohydrates, which may have existed in the region for millions of years. The benefits of their research extend beyond life on Earth. They could also shape future space exploration. A big part of why they’re investigating water ecosystems is because of the popularity around Saturn’s moon Enceladus and Jupiter’s Europa, Hubric said. She said it’s not a perfect analog, but it’s close enough that they can look for patterns in how life’s chemical processes might operate at these sites. “We hope that some of the questions we answer here find will help us in future endeavors when we do finally go explore the solar system,” Hubric said. Back on campus after the expedition, which ran from May 24 to June 6, they’ve started working to solve those questions by both identifying molecules that guide the search for life and by understanding the limitations of the instruments that can detect metabolites, or early signatures of life, Palmer said. “If [the instruments] can’t successfully identify traces of life on Earth, where we know there’s lots of life, how are they going to be successful in a place where it’s less likely than a needle in a haystack?” Palmer said. “It’s the bigger question of, what do we need to do in order to be successful in the search for life?” For Palmer and Hubric, research has only just begun. They’ll test water and sediment samples and the filtrate that they’ll remove from their water filters and investigate for microbes of interest. Searching for novel metabolisms will be an even more extensive process, Palmer said. “It’s weird doing something where you won’t be able to see the results for weeks or months,” Palmer said. “This is just the beginning.” Looking to know more about the Schmidt Ocean Institute’s (SOI) expedition through the Atacama Trench and Dr. Palmer's research?

The ISS is Leaking! What Happens Now? Florida Tech's Don Platt Can Explain

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.  November 18 - NBC News The coverage featuring Platt's insight is also being carried by Russian media and news sites.
