STEM-Talk is an interview podcast show produced by the Florida Institute for Human and Machine Cognition, a not-for-profit research lab pioneering ground-breaking technologies aimed at leveraging and extending human cognition, perception, locomotion and resilience. Twice a month, we talk to groundbreaking scientists, engineers and technologists. Our interviews focus on the science that our subjects are engaged with, as well as their careers, motivations, education, and passions. Think of them as “profiles in science.” Tune in every other Tuesday to our show—and if you like us, please write a review of STEM-talk on iTunes—and spread the word. <br />

Today we have the second installment of our interview with Dr. Michael A. Schmidt, the founder, CEO, and Chief Scientific Officer of Sovaris Aerospace, a company focused on assessments and solutions applied to humans in space and extreme environments on Earth.
In today’s interview, we talk to Michael about NASA’s plans to send humans to Mars and build permanent colonies on the Moon and Mars. We also talk to Michael about his recent book, “Building a Space-Faring Civilization,” which addresses the challenges of civilian spaceflight and the construction of space settlements.
In part one of our interview, Episode 182, we talked with Michael about his pioneering work in the field of precision medicine and how he has used it to improve the cognitive and physical performance of astronauts as well as NBA, NFL players and Special Operations forces.
In addition to his work with Sovaris, Michael also is a professor of aerospace medicine at the University of Central Florida College of Medicine, one of the few programs in the U.S. that offers a medical residency in aerospace medicine.

[00:03:00] Dawn picks up our interview from where we left off in part one, discussing the Human Research Program for Civilian Spaceflight. She goes on to mention that Chris Mason at Cornell University has a biobank of 1,500 samples across 22 astronauts and seven missions, and that these samples will lead to deeper insights on the effects of spaceflight on humans. Dawn switches gears to ask Michael about the cognitive and physical challenges of spaceflight over long duration missions.
[00:13:03] Following up on the cognitive challenges of long duration spaceflight, Ken mentions that the hippocampus, the primary memory center of the brain, has a relatively low radiation threshold compared to other tissues in the brain. Ken asks Michael to touch on the vulnerability of specialized brain tissues to radiation, particularly in the context of a long duration spaceflight to Mars.
[00:21:53] Ken mentions that it is understood that the APOE4/4 genotype is associated with impaired cognitive performance under certain circumstances and an elevated risk of dementia. While it is currently unknown whether APOE4/4 has any correlation of increased risk associated with cognitive impact resultant from environmental exposure due to spaceflight, Ken highlights the concern with sending APOE4/4-positive astronauts on long duration spaceflights without knowing the risks.
[00:29:26] Ken notes the worsened cognitive impacts resultant from medical radiation, and while therapeutic radiation is different than radiation experienced by astronauts, these results give some indication of the effects astronauts might experience.
[00:33:27] Dawn mentions that we recently had planetary scientist and director of NASA’s Haughton-Mars project, Pascal Lee, on the podcast, who explained his view that since there are so many engineering and biological challenges with going to Mars, we should take a more measured approach to a Mars mission, perhaps even beginning with a roundtrip to Mars rather than landing on our first visit. Dawn asks Michael what his thoughts are on this approach.
[00:37:29] Ken shifts the discussion to the subject of one of Mars’ moons, Phobos, and its potential role in a Mars mission.
[00:40:30] Dawn pivots to talk about Michael’s Book “Building a Space-Faring Civilization: Advancing the Renaissance of Science, Medicine and Human Performance in Civilian Spaceflight.” Dawn asks Michael to talk about the chapter concerning the question of space radiation from the standpoint of precision medicine.
[00:55:12] Dawn asks Michael to talk about the lack of appreciation people have for the fact that a Mars mission would be the most dangerous thing we’ve ever done.
[00:59:06] Ken mentions that Michael has worked with a lot of organizations, including Space X, which has a program, the Space X Mars Colonization Program,

Episode 183: Michael Schmidt on the challenges of building a space-faring civilization

Today we have Dr. Michael A. Schmidt, the founder, CEO, and Chief Scientific Officer of Sovaris Aerospace, a company focused on assessments and solutions applied to humans in space and extreme environments on Earth.  Michael is also a professor of aerospace medicine at the University of Central Florida College of Medicine, one of the few programs in the U.S. that offers a medical residency in aerospace medicine.

Michael is known for his work pioneering the field of precision medicine. He uses molecular analytics, coupled with physiologic and behavioral assessments, to facilitate human performance and resilience on Earth as well as in the extreme environment of space.

His work covers a spectrum from NASA, the NFL, the NBA, U.S. Olympic teams, Nike, SpaceX, Axiom Space, NASCAR, Special Operations, the Naval Submarine Medical Research Lab, the Mayo Clinic, and others.

We had a long and fascinating conversation with Michael and decided to break the interview into two parts. This episode focuses on Michael’s background and the cognitive and physical challenges astronauts experience in spaceflight. We also dive into the many ways that precision medicine is facilitating human performance and resilience here on Earth. In part two of our conversation, Michael talks about his work with NASA and SpaceX on the challenges of civilian spaceflight and the future of Mars exploration, including the construction of permanent colonies on the Moon and Mars. You won’t want to miss that conversation.

Show notes:

[00:03:59] Dawn opens our interview mentioning that Michael grew up in Minnesota in a small farming community, asking if it’s true that he sometimes had to do chores in 20- to 30-degree weather.

[00:06:50] Dawn asks if it is true that Michael fell in love with science at a young age, even building telescopes at the age of 11.

[00:08:00] Dawn asks Michael what it was that led him to become so fascinated with space specifically.

[00:08:58] Dawn asks if Michael ever thought about becoming an astronaut.

[00:10:09] Ken asks if it is true that Michael was a big reader as a child.

[00:11:21] Dawn asks Michael to talk about his childhood athletic interests.

[00:11:55] Dawn asks how it was that a high school quarterback from a small town in Minnesota ended up at university in the United Kingdom.

[00:13:38] Ken asks Michael what years he worked at NASA Ames Research Center.

[00:14:51] Ken mentions that when Michael was at NASA Ames, he did work collecting molecular and physiologic assessments of humans using NASA’s 20-G centrifuge. Ken asks Michael to talk about the centrifuge and how he used it in his studies of hypergravity.

[00:17:49] Ken comments on the fact that pieces of equipment like NASA’s 20-G centrifuge are a precious scientific resource, and when they cease functioning, unfortunately, they are unlikely to be replaced.

[00:19:40] Ken and Michael discuss the fact that microgravity, despite being one of the most pressing effects on astronaut health, is the one of the least addressed problems in human spaceflight.

[00:21:48] Ken explains that Michael is the founder, CEO and Chief Scientific Officer of a company called Sovaris Aerospace, which is focused on assessments and solutions applied to humans in space and extreme environments on Earth. Ken asks Michael where the idea came from to found this company.

[00:24:35] Dawn explains that since the human genome was first sequenced, there has been an acceleration of genome-based technologies that have made it possible to consider a person’s genetic makeup, both in healthcare and optimizing performance. Dawn asks Michael to talk about the work he does applying genomics to human spaceflight.

[00:28:52] Dawn asks about Michael’s direction of the molecular profiling and precision medicine efforts for the Golden State Warriors during their record-breaking 73-9 season

[00:32:57] Dawn mentions that Michael published a review in the journal Meta...

Michael Schmidt discusses the application of precision medicine to human spaceflight

Our guest today is Dr. Ken Forbus, the Walter P. Murphy Professor of Computer Science and a Professor of Education at Northwestern University.

Joining Dr. Ken Ford to co-host today’s interview is Dr. James Allen, who was IHMC’s associate director until he retired a few years ago. James is a founding fellow of the American Association for Artificial Intelligence and a perfect fit for today’s discussion with Dr. Forbus, who, like James, is an AI pioneer.  Back in 2022, James was named a fellow by the Association for Computational Linguistics, an organization that studies computational language processing, another field he helped pioneer.

Dr. Forbus also is a Fellow of the Association for the Advancement of Artificial Intelligence and was the inaugural winner of the Herbet A. Simon Prize for Advances in Cognitive Systems. He is well-known for his development of the Structure Mapping Engine. In artificial intelligence and cognitive science, the Structure Mapping Engine is a computer simulation of analogy and similarity comparisons that helped pave the way for computers to reason more like humans.

Show Notes:

[00:03:07] Ken opens the interview with Dr. Forbus by asking if it is true that he had an unusual hobby for a nerdy kid growing up.

[00:04:18] James mentions that Dr. Forbus’ family moved often when he was younger and asks how that affected him.

[00:05:18] Ken mentions that when Dr. Forbus was in high school, he filled his free time reading about psychology and cognition before eventually coming across some articles on AI. Ken asks Dr. Forbus to talk about this experience and what happened next.

[00:07:49] James asks Dr. Forbus if he remembers the first computer he owned.

[00:09:17] Ken asks Dr. Forbus if there was anything, other than its reputation, that led him to attend MIT.

[00:10:09] James mentions that for the past few decades, Dr. Forbus has been working on developing “human like” AI systems. While much of AI research and development has been focused on meeting the standard of the Turing test, James asks Dr. Forbus why he is not a fan of the Turing test.

[00:12:24] Ken mentions that Dr. Forbus received his Ph.D. from MIT in 1984, the same year that Apple released the first Macintosh, which was rolled out with a famous Super Bowl ad. This computer was the first successful mouse driven personal computer with a graphical interface. Ken asks Dr. Forbus what he remembers about that ad, and what his reaction to it was at the time.

[00:13:22] James mentions that 1984 was also the year that Dr. Forbus made his first splash in the AI world with his paper on qualitative process theory. James goes on to explain that at the time, qualitative reasoning regarding quantities was a major problem for AI. In his paper, Dr. Forbus proposed qualitative process theory as a representational framework for common sense physical reasoning, arguing that understanding common sense physical reasoning first required understanding of processes and their effects and limits. James asks Dr. Forbus to give an overview of this paper and its significance.

[00:18:10] Ken asks Dr. Forbus how it was that he ended up marrying one of his collaborators on the Structure Mapping Engine project, Dedre Gentner.

[00:19:14] James explains that Dedre’s Structure Mapping Theory explains how people understand and reason about relationships between different situations, which is central to human cognition. James asks Dr. Forbus how Dedre’s theory was foundational for the Structure Mapping Engine (SME).

[00:25:19] Ken mentions how SME has gone through a number of changes and improvements over the years, as documented in Dr. Forbus’ 2016 paper “Extending SME to handle large scale cognitive modeling.” Ken asks, as a cognitive model, what evidence Dr. Forbus has used to argue for the psychological and cognitive plausibility of SME.

[00:30:00] Ken explains that many AI systems rely on deep learning,

Today we have planetary scientist Dr. Pascal Lee and STEM-Talk host Dr. Ken Ford in a wide-ranging conversation about NASA’s ambitions to return humans to the Moon as a stepping stone to sending astronauts to Mars.

Pascal is making his third appearance on STEM-Talk. Much of his research focuses on asteroids, impact craters, and the future human exploration of Mars. Pascal and Ken have a lively discussion about the growing momentum for space exploration.

Pascal is a researcher at the SETI Institute, a not-for-profit NASA program focused on searching for extraterrestrial intelligence in an effort to understand and explain the origin and nature of life in the universe. He also is the co-founder and chairman of the Mars Institute, and director of the Haughton-Mars Project at NASA Ames Research Center.

Last year, Pascal received significant news coverage for his discovery of a giant volcano along with a possible sheet of buried glacier ice in the eastern part of Mars' Tharsis volcanic province. This was the first geological find of this magnitude since the other major volcanos on Mars were discovered back in the 1970s.

Show notes:

[00:03:06] Ken welcomes Pascal back to STEM-Talk and starts our interview by mentioning the developments in space exploration over the past few years, including civilian space missions, NASA’s Artemis program which aims to send humans back to the moon, and commitments to a manned mission to Mars. Given Pascal’s career in advancement of space exploration, Ken asks if Pascal is excited by these recent developments.

[00:04:43] Ken explains that for a couple of decades Pascal has spent his summers visiting Devon Island in the Canadian arctic archipelago, which is the largest uninhabited land on Earth. When Pascal was last on STEM-Talk, his annual trip to Devon Island was cancelled due to COVID-19. Devon Island has unique geological characteristics that are in some ways similar to those on Mars. Since 2001, Devon Isalnd has been the home of the Haughton Mars Project (HMP). Ken asks Pascal to talk about the advances in this project since his last appearance on STEM-Talk.

[00:07:59] Ken mentions that while much conversation has been centered on a human trip to Mars, a mission to return humans to the Moon and establish a permanent base is a more immediately feasible goal in the short term. Ken asks Pascal to talk about the importance and significance of such a mission.

[00:12:06] On the topic of a Moon base, Ken explains that NASA’s Artemis project aims to send humans to the south pole of the Moon. Pascal has written a paper on that topic titled “An Off-Polar Site Option for the NASA Artemis Space Camp.” Ken asks Pascal what he sees as the primary weakness in the south pole location.

[00:20:25] Ken agrees with Pascal’s perspective on sending humans to the lunar south pole, and the two discuss the problems with focusing human space exploration on romantic ideas such as “living off the land.”

[00:22:24] Ken follows up on the previous questions by mentioning that in Pascal’s aforementioned paper, he suggests setting up a lunar base at the floor of the Clavius crater. Ken asks Pascal to talk about Clavius and why it is a potentially good permanent location for a moon base.

[00:27:56] Ken asks Pascal how confident he and the community at large is in the Sophia finding of water.

[00:29:00] Ken notes that contemporary interest in human space exploration appears tied to current geopolitical issues, much like the first space race between the US and USSR. Today, interest in space travel is closely linked with relations between the US and China. Ken asks Pascal to discuss this and how he believes the US should view this current situation.

[00:35:43] Ken asks Pascal what he knows about the China’s current plans for a lunar mission.

[00:34:36] Ken talks about a meeting at IHMC that addressed power-beaming to the lunar surface.

[00:39:01] Ken notes that there is a lot of talk the...
