Louis Stodieck is stepping back from bioastronautics after nearly five decades at the leading edge of research.

A three-time graduate of the ��ý��, Stodieck (AeroEngr BS’79, MS’81, PhD’85) has spent almost his entire career on the Front Range, but his work is literally out of this world. He has been part of BioServe Space Technologies on campus since it was founded in 1987. The center recently celebrated its 100th orbital payload launch to space.

“The launches never become ordinary,” said Stodieck, a professor emeritus in the Ann and H.J. Smead Department of Aerospace Engineering Sciences. “Our first launch was an extreme learning curve; you can’t even imagine getting to it, having something on the space shuttle and getting launched.”

Stodieck grew up on a ranch in northern Nevada. His two older brothers would become electrical engineers. Stodieck was drawn to space.

“Aerospace was very much my priority. Back then there was no online. You had to go to the library to pick up catalogs to figure out which schools had aerospace programs,” Stodieck said.

He applied to CU ��ý�� in part for the quality of the engineering program and also for Colorado’s outdoor opportunities.

After finishing his undergraduate degree, he considered going into industry, but the allure of research was strong, and an aerospace faculty member, Marvin Luttges, had funding to take him on as a graduate student.

“The work was more biomedical engineering related. I loved physiology and biology. They complemented my more traditional engineering training,” he said.

At that time, space payloads were almost exclusively the domain of NASA, but in 1987, that changed.

“Congress required NASA to create centers for the commercial development of space and to accept commercial payloads. There was almost no one in the agency that supported it. Commercial payloads were a four-letter word,” he said.

Luttges submitted a proposal to start a center at CU ��ý��, which would become BioServe. Stodieck, who had been completing a postdoc at the University of British Columbia, was drawn back to Colorado to join the team.

It was rough going at first.

“We were trying to promote industry getting involved in the space program, and the first question from companies was always, ‘Well, why would I want to do that?’ Today, there’s much more interest,” he said.

In those early years, BioServe was sending up one or two payloads annually. Today they launch nearly 15 payloads each year, ranging from studies of cell cultures and bacteria to pharmaceutical research. BioServe has also developed permanent hardware used on the International Space Station, including incubators, microscopes and refrigerators to store astronaut food and medications.

Their budget is approximately $5 million each year, funding generated from work with universities and businesses worldwide. If an organization wants to do life science research in space, BioServe can make it happen. The Mayo Clinic, Goodyear, Sanofi Pasteur, and the Aerospace Corporation have all worked with them to develop experiments.

As years passed, Stodieck’s responsibilities at BioServe increased; in 1995 he was promoted from research associate to assistant research professor. In 1999, he was asked to lead the entire center, a position he would hold for 20 years.

He faced particular challenges in 2006 when NASA ended funding for the commercial space program. It was no longer an issue of the agency not trusting commercial providers, they had proven their worth; it was simply a change in leadership priorities.

“At that time, there were 16 centers like ours. After 2006, almost all of them closed. That transition was extremely difficult. We navigated it because we were determined to do so. We strongly felt our program should continue, along with key champions inside NASA,” he said.

In 2019, Stodieck stepped back from the director role to become BioServe’s chief scientist, a role that focused entirely on research. It was an attempt at a phased retirement. Stodieck anticipated he would continue working for another two to three years. It has now been six.

“The last few years all of the work has been with human cells, tissues and lab on a chip systems. This is an area that has potential to treat cancer, blood disorders, autoimmune issues. That’s all really exciting and it’s hard to step away,” Stodieck said.

Although he is now retired, Stodieck is not slowing down. Both he and his wife enjoy traveling and the Colorado lifestyle, including hiking and climbing. They recently went rafting in the Grand Canyon with their two adult daughters.

“I don’t ever see sitting around very long,” he said. “It’s time to see what’s next.”

Research in space, helping people on Earth: BioServe marks 100th orbital launch

Research in space, helping people on Earth: BioServe marks 100th orbital launch Jeff Zehnder Mon, 04/21/2025 - 14:28

Louis Stodieck remembers the first time he saw a space shuttle blast off from NASA’s Kennedy Space Center in Florida. In April 1991, Stodieck, an aerospace engineer, was the associate director of BioServe Space Technologies, a research center at the ��ý��.

He had helped to design a set of test tubes that would, among other things, not spill the moment they reached space. Stodieck handed the test tubes off to a NASA crew, then watched as his work lifted away from a launchpad aboard the space shuttle Atlantis.

“I never get tired of launches,” said Stodieck, who served as BioServe’s director from 1999 to 2019 and is now its chief scientist. “The sound reaches you seconds after the launch because you’re a few miles away. When it hits you, it’s this low vibration, and you just feel it.”

BioServe, which was founded in 1987, works with scientists at companies and research institutions around the world to conduct life science experiments in space.

Today, Stodieck and his colleagues are celebrating a new milestone: BioServe’s 100th launch into orbit.

On Monday, April 21, a SpaceX Dragon capsule lifted off from a similar pad in Florida en route to the International Space Station (ISS). It carried equipment belonging to three research projects, or “payloads,” developed by BioServe. They include several colonies containing billions of bacteria and algae.

“This launch is an amazing milestone,” said Stefanie Countryman, the current director of BioServe. “It exemplifies the hard work of everybody at BioServe, not just our engineers and researchers, but also our students.”

The center has come a long way since that first launch, NASA’s STS-37 mission, in 1991.

Researchers at the center have since sent a wide range of living things into orbit. They include single-celled organisms but also ants, silkworms, mice and an intrepid “spidernaut” named Nefertiti. (An 18-year-old student from Egypt proposed studying whether Nefertiti, a jumping spider, could adjust her hunting techniques in space, which she did). But BioServe has also kept one foot planted on the ground. The center’s research has generated new insights into human medical conditions like bone loss and cancer—and could even lead to facilities in the not-so-distant future that orbit Earth while making human stem cells.

“Space gives us an opportunity to look at organisms in new ways, including how they may express genes differently than they do on Earth,” Countryman said.

Single-celled astronauts

David Klaus, professor at the Ann and H.J. Smead Department of Aerospace Engineering Sciences, was a graduate student at CU ��ý�� when BioServe’s first launch took off. From 1985 to 1990, he worked as a shuttle launch controller at the Kennedy Space Center in Florida and in Mission Control in Houston. Klaus is set to retire this spring and sees the 100th BioServe launch as a “bookend” on his career.

In those early days, BioServe’s work largely revolved around one challenge of conducting science from hundreds of miles above Earth—open liquids and space don’t mix.

“It’s not like taking two test tubes in a lab on Earth and mixing them together,” Klaus said. “With our early payloads, we were really just trying to figure out how we could manipulate biological fluids in a space environment and get some initial experimental results.”

BioServe began as a 5-year grant from NASA under founder Marvin Luttges, a professor of aerospace engineering sciences at CU ��ý��. Klaus explained that the center’s space test tubes include up to four sealed chambers. If you push down on a plunger, you can mix the fluids in those chambers one by one, all without exposing them to the air. BioServe has since sent thousands of its test tubes into space, and the basic design remains largely the same.

The team’s early research also revealed something surprising: BioServe scientists discovered that bacteria tend to grow better in space than they do on Earth—perhaps because they’re not being squished down by gravity. A handful of experiments showed that such bacteria could even be transformed into living factories for making anti-cancer drugs.

In the decades that followed, BioServe’s scientific equipment wound up on NASA’s four space shuttles, the Russian space station Mir and, eventually, the ISS, which entered into orbit in 1998.

Today, astronauts on the ISS can peer through a microscope flight certified and launched by BioServe and grow cell cultures in four incubators called Space Automated Bioproduct Lab (SABL) 1, 2, 3 and 4. BioServe even supplied the refrigerator where humans on the ISS store their food. On the ground, the center runs a mission operation and control center on the CU ��ý�� campus. There, BioServe staff talk to astronauts in real time on a giant screen.

“We’re replicating the sorts of biological labs that you can find at CU ��ý�� in space,” said Tobias Niederwieser, a research associate at BioServe.

The center has also collaborated with dozens of space agencies, universities and private companies over its history. On the current launch, for example, a company called Sophie’s Bionutrients based in the Netherlands contracted with the center to examine how algae produce proteins in space—which the company hopes will lead to new kinds of algae-based meat substitutes.

The center’s most lasting contribution to science, however, may be its students. Over the years, hundreds of undergraduate and graduate students at CU ��ý�� have worked for BioServe. Many have gone on to jobs at NASA and private space companies.

They include Adeline Loesch, a senior studying atmospheric and oceanic sciences at CU ��ý��. She started working at BioServe between her freshman and sophomore years. These days, she does a little bit of everything for the center: She helps to build the hardware for experiments, assembles them for flight and sits in the operations center as astronauts carry out the research.

In the fall, Loesch will start work in spacecraft and satellite flight operations for Lockheed Martin in Colorado.

“My favorite is watching the projects come full circle during the operations,” Loesch said. “Watching the research being done in real time by astronauts in space is the coolest thing ever.”

Making humans healthier from space

In the end, BioServe’s research in space doesn’t stay in space.

Roughly 24 years ago, for example, Stodieck and his colleagues designed a specialized habitat for mice to live on the ISS. His team’s research has revealed new clues to why mammals lose bone mass when they leave Earth. Those insights, in turn, helped to inspire new kinds of medications for osteoporosis in people.

Niederwieser, meanwhile, is tackling what may be an even more ambitious goal—he and his colleagues are growing human hematopoietic stem cells in space. Doctors often transplant these cells into people to treat cancers like leukemia and lymphoma.

But they’re also tricky and expensive to make on Earth. In a few early experiments, Niederwieser and his colleagues discovered that stem cells, like bacteria, may grow more freely in space. Later this year, his team plans to transport a facility for producing stem cells en masse to the ISS.

That could lead to a new vision for space—one in which stations in orbit around Earth produce various treatments for human illnesses, then send them back to patients on the ground.

“Humans have been on this planet for hundreds of thousands of years and have evolved with only one gravity,” Stodieck said. “It’s really been a privilege to understand how organisms work in another environment.”

Stodieck didn’t travel to Florida for Monday’s launch, but Klaus was there to see SpaceX’s Falcon 9 rocket roar off the launchpad. Before he left, he was feeling wistful about seeing his old stomping grounds again.

“I'm looking forward to going down there and reminiscing a little bit,” Klaus said. “I’ll drive around and look at the base—a little 40-year flashback to where my career started.”

CU ��ý�� leading effort with CU Anschutz, Mayo Clinic to use microgravity to grow stem cells

The ��ý�� is leading a $3.3 million project to advance stem cell research in low Earth orbit.

NASA has awarded the university’s BioServe Space Technologies a three-year grant to study the use of microgravity to grow hematopoietic stem cells (HSCs). The cells, which will come from umbilical cord blood or bone marrow, show potential to treat serious medical conditions including blood cancers that require bone marrow transplants, fatal blood disorders, severe immune diseases, and certain autoimmune diseases, such as rheumatoid arthritis.

“The field of bio-regenerative medicine is rapidly expanding, and there is enormous potential to treat a broad set of diseases and organ failure,” said Louis Stodieck, BioServe’s chief scientist and a research professor in the Ann and H.J. Smead Department of Aerospace Engineering Sciences. “Microgravity offers us the opportunity to try to mimic the human body in a way you can’t in a cell culture dish or bioreactor here on Earth.”

Collaborating with BioServe on the research are ClinImmune Cell and Gene Therapy at the CU Anschutz Medical Campus, Mayo Clinic, and RheumaGen, a company that grew out of research at CU Anschutz.

“Successful expansion could grow the cord blood resource pool as well as transplant potential,” said Louise Helander, medical director of ClinImmune. “The possibility of improving precursor HSC expansion of gene-edited cells could be the gateway to expanding bioregenerative medicine options for multiple medical conditions and will help expand access to the growing interest of providing personalized medicine in the form of HSC treatments.”

The work will include development of a bioreactor that can grow stem cells in space more effectively and efficiently than can be done in ground labs. Once grown, the cells would be cryogenically frozen and brought back to Earth as medical treatments. It is cutting-edge research with major possibilities.

“I won’t say there is anything simple about this, doing it in space, but expanding these cells on the ground they are subject to a lot of shear stresses in stir tanks that can cause damage or induce them to differentiate and turn into something that’s not useful,” Stodieck said. “In microgravity, we can grow them in an environment that’s similar to your body, where they can stay suspended and essentially mimic the environment in your bone marrow.”

BioServe has decades of experience with life science research in orbit, and currently has several similar cell culture systems on the International Space Station for other analyses.

While conducting research in space is expensive, companies like SpaceX have made major advancements in cutting costs for rocket launches, and NASA believes there is additional potential for cost reductions, making biomedical research more financially viable.

“This has to be cost competitive with ground treatment or demonstrate a significant medical advantage,” Stodieck said. “As we get further into the work, NASA also expects us to have outside investors to make the process viable. NASA’s whole premise is to create commercial opportunities in orbit using the space station, which will drive costs down.”

If the team is successful, the technology will enable cell therapy transplantation, especially in children and younger adults, where long-term bone marrow cell repopulation is critical to lifetime health.

“There are a lot of questions to answer, but that’s why we do research,” Stodieck said. “In addition, much of the technology we develop for this could also apply terrestrially. We could improve bioreactors more broadly to expand stem cell research and medical treatments in space and here on Earth. I’m very excited.”

The first 20 star-trekking mice to travel to the International Space Station, riding aboard a spacecraft built by Hawthorne-based Space X, have returned to their home lab at UCLA.

But the mission isn’t over for the mice, plucked last week from their capsule in San Pedro, according to a scientist participating in the project that aims to help humans battle bone loss.

For now, the pioneering rodents are awaiting their rodent counterparts, still orbiting 220 miles above Earth on the space station’s National Lab. And they’re getting reacquainted with life back on Earth, dealing with such challenges as normal gravity.
