Introduction

> Experiencing the harsh realities of nature can be incredibly humbling; when my friend mentioned the volcano starting to "rot," it struck me with a sudden realization about survival and vulnerability—I felt my adrenaline kick in, almost like a moment of tunnel vision, where the sheer weight of our existence comes into focus.

> As an astrobiologist, I thrive on exploring the extreme environments of our planet, from volcanic lakes to the depths of the universe. Each dive and each encounter pushes me closer to understanding where life might exist beyond Earth, and I hold onto that idea with passion and determination.

Working in extreme environments

> Exploring extreme environments on Earth has provided profound insights into the possibilities of life beyond our planet. By studying organisms that thrive in conditions analogous to Martian environments, I’ve been able to frame and refine the hypotheses regarding the habitability of Mars, especially looking at ancient water bodies like lakes in impact craters.

> My work is fundamentally driven by profound questions about the origin and nature of life. Mars exploration was a stepping stone, helping me grasp conditions from billions of years ago and guiding the search for life's clues. Over 25 years, my curiosity has evolved from merely pondering extraterrestrial life to deeply understanding life’s emergence and persistence.

Water and life on Mars

> Looking back at the early exploration of Mars, there was a shift from expecting extraterrestrial civilizations to focusing on understanding the planet's geology and potential for life. The disappointment turned into excitement as we discovered volcanoes, valleys, and ancient channels on Mars, sparking new scientific imagination and curiosity.

> If life did exist on Mars, signs to look for would include morphological traces of interaction with the environment, such as stromatolites or chemical traces like C12 and methane. By exploring ancient lakes and impact craters, we aim to uncover clues from Mars' past that could reveal hints of past life and the planet's potential for supporting life.

Origin of life

> The concept of panspermia fascinates me because it suggests that the building blocks of life are scattered across the universe, but it still leaves the ultimate question unanswered: "What is the origin of life?" I find it compelling that these elements are abundant in places like the interstellar medium, waiting for the right conditions, like water, energy, and nutrients, to support life.

> "If we're a civilization here on Earth and we survive another few hundred years, it would be a good idea to take a big gun and just shoot life out there," exploring the idea of sending simple organisms or even our own DNA into space to ensure life persists beyond our planet. However, while that sounds like a backup plan, I also believe that taking care of our home is crucial.

> I'm particularly interested in understanding "the nature of life" rather than just searching for life itself. Life isn't just about biochemical processes; it's about how we gather, store, and share information. This interconnectedness draws a fascinating parallel between the structure of our languages and the building blocks of biological life, creating a "mandelbrot universe" where patterns repeat through complexity.

> The evolution of intelligent life, including the pivotal Cambrian Explosion, reminds us that "mass extinctions will drive what's the endgame." Our position in the galaxy and the geological history of planets affect evolution significantly. This suggests a multitude of possibilities for life elsewhere, although our bias as Earth-bound beings limits our perspective on how truly diverse life could be in the cosmos.

Complexity

> Life and complexity are deeply intertwined, and I believe that life permeates the entire universe with different "flavors" of complexity manifesting in various ways. This complexity isn't just about human intelligence; even entities like cyanobacteria, which have survived for billions of years, demonstrate an intelligence about their environment. Complexity could be seen as the capacity to gather, store, and use information, and we need to acknowledge that our conventional understanding may be limited by our biases.

> The universe’s interconnected nature leads me to contemplate that this vast cosmos is a living force, continuously becoming more complex and self-aware. I resonate deeply with Carl Sagan’s idea that "we are the universe trying to understand itself." As we explore and possibly discover the process of life beyond Earth, we might open a window to a universe that is dynamically alive, possibly intelligent, and conscious. This quest isn't just about finding origins but understanding a universal process that brings life and complexity into an illuminating connection.

AI

> AI as a tool: "AI is not aware AI is being built by humans... as long as we use it as a tool it remains a tool."

>

> Co-evolution with technology: "The singularity is the co-evolution of humans with technology... it's the relationship with technology as a complete change to me."

> Hope in science and equilibrium with the planet: "Revolutions in cosmology, astrobiology, and astronomy bring hope... we need to be in equilibrium with the planet to move forward."

Extinction

> There’s a flicker of optimism within us, despite the chaos around, as we’ve managed to find a balance in the face of existential threats, similar to what we did during the nuclear age; we are indeed clever, like “clever teenagers,” always evolving. However, it's imperative we recognize that, unlike our predecessors, our current mentality lacks the same decency and moral values, leaving me concerned if we can reach true maturity as a civilization in this chaotic landscape.

> When I ponder the universe, my heart leans towards belief in life's abundance beyond Earth; the statistical odds simply suggest we can't be alone. Yet, I reflect on the impermanence of existence, the cycle of rise and extinction in the cosmos, which makes me wonder if we're simply a unique phenomenon—survivors amid a vast narrative of creation and decay.

Fermi Paradox

> Re-evaluating the Fermi Paradox and the Search for Extraterrestrial Life: The Fermi Paradox is often viewed through an anthropocentric lens, limiting our understanding of the universe. I argue that "we're not yet capable of picking it up," emphasizing the need to study life's complexity on Earth first. An example is the "shadow biosphere," which proposes that life might have taken multiple, unrecognized forms here on Earth, challenging our conventional definitions and search methods.

> The Role of Scientists in UFOs and Public Perception: While 95% of UFO sightings can be explained by natural phenomena or secret projects, it’s the unexplained small percentage that intrigues me. There's a clear division between studying extraterrestrials in their natural habitat versus investigating UFOs. The folklore around UFOs has undeniably harmed the scientific community, "and this has been a huge disservice," but recent governmental interest in scientifically examining UAPs is a positive shift.

> Communicating Science Effectively: It’s essential for scientists not only to conduct rigorous research but also to engage with the public to foster wonder and understanding. Communication plays a critical role in garnering support and funding for scientific endeavors. At The Institute, we strive to balance rigorous peer-reviewed research with public engagement, as "we have more Public Presentation... than peer-reviewed articles," ensuring that scientific discoveries are accessible and inspiring to all.

SETI research

> The Search for Extraterrestrial Intelligence (SETI) Institute is not just about the search for signals; it's about exploring life in the universe, from the origins of life to extraterrestrial intelligence. About 90% of our work is focused on exoplanets, studying data and signals to understand planetary environments and the possibility of life beyond Earth.

> Our Institute has evolved from its origins in SETI to a comprehensive search for life across the Drake equation. We work at the intersection of disciplines, involving astrobiologists, astronomers, and more to explore the diverse possibilities of life in the cosmos. This multi-disciplinary approach allows us to make groundbreaking discoveries at the nexus of different fields, making it a truly exciting and privileged time for the Institute.

Diving in volcanic lakes

> Exploring volcanic lakes at high altitudes is not just about scientific inquiry; it's a thrilling adventure that combines athletics and extreme environments. "It’s to get data and more knowledge, so there are so many stories."

> My experiences are often defined by moments that feel almost transcendental. Diving in those lakes, I have felt a profound connection with the universe, saying, "I was surrounded by Golden darts... it was an absolute awareness."

> Overcoming childhood fears has shaped my journey. I turned my "rational fear of pressurized vessels" into a mastery of free diving, "because as a scientist, I needed more time at the bottom of the lake."

> Training is essential, especially in high-risk environments. The rigorous preparation with Navy Seals taught me to maintain focus and composure, transforming challenges into learning experiences: "Your training allows you that space to keep you cool and composed."

Surviving an earthquake on a volcano

> Surviving a 7.8 magnitude earthquake 50 meters from a volcano summit tested every aspect of our rigorous NASA training. The "acts of God" like volcanic eruptions and avalanches are beyond control, but the preparedness from NASA's protocols kept us from panicking. We knew exactly how to react even under such duress, proving the importance of preparation.

> The uliplano scene from 20,000 feet is surreal; it's like a time machine to early Earth. As scientists, we had a job to do even amidst chaos. Half a dozen of us, amidst the stunning but precarious surroundings, continued our work in the crater. My young Bolivian assistant exemplified calmness, allowing the mission to proceed despite my radio limitations.

> Facing imminent danger from potential sulfuric acid clouds and avalanches, survival instincts kicked in hard. Decisions had to be rapid and concise. Emotions hit hardest once safety was assured, with adrenaline draining away completely. The human body and mind's response to survival is an extraordinary testament to resilience and evolution.

Resilience of life

> Exploring Mars reveals the resilience of microorganisms surviving harsh conditions, teaching us about adaptation through time and environmental changes. It's fascinating to see how life prevails in extreme environments, showcasing the diversity and adaptability of life on Earth.

> Life on Mars and in extreme environments on Earth demonstrate the survival of the fittest through evolution. Adaptable microorganisms have thrived for billions of years, showing how life persists and evolves in the face of challenging conditions.

Life below the surface of Mars

> The environment of early Mars was surprisingly favorable for life, possibly even more so than early Earth. Mars might have been habitable and may have experienced life's beginnings earlier, but "unambiguous evidence of life is going to be something interesting to prove," as we still grapple with defining what life really is.

> I believe that "life might not be so far from the surface" of Mars as we think. There's evidence suggesting that stable habitable zones could exist just beneath the surface, where both natural climate changes and deeper subsurface conditions may allow life to survive or even thrive.

> Understanding habitability requires focusing on the scale that matters for microbes. "We need to do a better job" with environmental data collection on Mars, mapping those critical microbial habitats, which will enhance our search for life and also aid in human exploration efforts.

Depression

> Reflecting on my life's journey, I've realized that the profound challenges I faced during my troubled teenage years, including a struggle with suicidal thoughts, were monumental in shaping who I am today. The irony of being so close to losing life and then dedicating myself to understanding its origin and nature has given me an unyielding perspective. It taught me to see the beauty in life and instilled a relentless drive to climb both literal and metaphorical mountains. This lesson has become a core message of my life: never give up, always give tomorrow a chance, because you never know what incredible things lie ahead.

> Another defining moment occurred when I nearly drowned while trying to save someone else. Witnessing the finality of that man’s end resonated deeply with me. It served as a powerful reminder that, unlike him, I had the chance to pursue my dreams and answer the burning questions that drive my curiosity. This experience fortified my resolve to embrace life fully and to seize every opportunity. It underscored the importance of perseverance and the potential that exists in every new day, no matter how bleak the present might seem.

Mortality

> Reflecting on mortality and love, losing my husband has been the toughest mountain to climb. He taught me to live each day fully and trust in life, a lesson I draw from daily to find happiness despite the pain of his absence.

> Love is the force driving the universe, a love that humanity must cultivate universally, beyond personal relationships. It could guide our exploration of space, like settling on Mars with a focus on love and care for our planet Earth, facing the responsibility as the dominant species to protect and preserve all life forms on our biosphere.
