Space Café Podcast - Navigating Our Interplanetary Ambitions

The Episode

In March 2022, Europe’s ExoMars Rosalind Franklin mission was only weeks from launch when it was suddenly grounded.
Russia’s invasion of Ukraine ended years of cooperation, and left one of ESA’s most ambitious Mars projects without a ride, without partners, and without a plan.

From inside ESA’s Mission Control in Darmstadt, Sara Melloni watched everything freeze. As Mission Operations Manager for Rosalind Franklin, s...

Dr. Pascal Lee, planetary scientist, Arctic field explorer, and professor at the KSU (Kepler Space University)

He’s spent his life between two extremes, the frozen frontiers of the Arctic and the conceptual edges of space exploration. Few people connect fieldwork, engineering, and philosophy like Pascal does.

Guest: Robert Meisner, Earth Observation, ESA, ESRIN

The Cosmic Scoop:
In this eye-opening episode, Markus travels to ESRIN, ESA’s Earth Observation hub in Frascati near Rome, to sit down with Robert Meisner – a man who has spent nearly 40 years watching our planet from above. Together they dive into the hidden landscapes of the ocean surface, the secrets of gravity maps, and how satellites reveal the slow but relentless transf...

John McFall — surgeon, Paralympic medalist, father of three, and ESA parastronaut selectee — joins Markus to explore how human spaceflight changes when we design for ability, not assumptions. From winter survival in the Pyrenees to EVA realities and cosmic radiation, John shares what it takes to open space to everyone.

Guest:
Dr. Andy Tomkins – Geologist, Professor at Monash University, and lead author of the groundbreaking study proposing that Earth once had a Saturn-like ring system.

The Cosmic Scoop:
What if Earth once had rings like Saturn? Dr. Andy Tomkins joins Markus to unravel the evidence that, 466 million years ago, a colossal asteroid breakup may have encircled our planet with a shimmering band of debris. From the science of anc...

Guest: Dr. Bhavya Lal – Former NASA Chief Technologist, MIT-trained nuclear engineer, and architect of U.S. space nuclear policy.

The Cosmic Scoop:
Nuclear power’s bad Earthly reputation hides its potential as a lifeline beyond our planet. Space is already radioactive—and if we want to stay and build on the Moon, Mars, or Europa, nuclear offers “power abundance” solar can’t match. Dr. Lal explains why, covering tech, safety, la...

This week, Simonetta Cheli, Director of Earth Observation Programs at the European Space Agency (ESA), joins Markus to dive into one of the most ambitious and groundbreaking projects of our time: building a digital twin of our planet. Through Destination Earth (DestinE), ESA is creating a dynamic, real-time model of Earth—a tool designed to simulate future scenarios, test the impact of human decisions, and ultimately help us better...

Giorgio Saccoccia – former President of the Italian Space Agency (ASI), propulsion engineer, and lifelong “space fan.” From lunar outposts and electric thrusters to space-as-diplomacy, Saccoccia brings four decades of insight into turning quick “flags-and-footprints” missions into a permanent human presence beyond Earth.

🚀 The Cosmic Scoop

In this expansive and deeply human conversation, Phnam Bagley challenges everything we think we know about architecture. From floating tables to engineered space hearts, she reimagines what it means to design for a future where gravity is optional and emotion is essential.

Together, we explore the untold questions of life in space:

• What is a “table” without gravity?
• Can architecture heal isolation?
• Do space-born ...

Guest: Wanda Diaz Merced

This very special episode of the Space Café Podcast introduces Wanda Diaz Merced, a visionary scientist who, after losing her sight in her twenties, pioneered a groundbreaking new method of exploring space through sound—sonification. Wanda shares her remarkable story and insights, showing us that blindness does not limit one's ability to explore the cosmos but rather enriches it with a rare new perspect...

Guest Introduction:
In an extraordinary fusion of art, engineering, and cosmic ambition, Swedish artist Mikael Genberg and space engineer Emil Vinterhav have realized what many deemed impossible—a traditional Swedish red house, journeying through space toward the lunar surface. This Moonhouse symbolizes humanity’s unyielding aspiration and our innate desire to explore, challenge limits, and leave lasting footprints in new world...

This episode's guest, Dr. Heather Collins, cognitive neuroscientist, brain-hack expert, and sought-after keynote speaker, takes us on a fascinating - and slightly unsettling - journey into how space travel changes the human brain. Buckle up as Heather reveals the extraordinary findings and crucial insights at the forefront of cognitive neuroscience, helping us understand not only space’s impact on our minds, but how to unlock ...
