The Space Show by Dr. David Livingston John Batchelor Hotel Mars with Dr. Sara Seager on ionic liquids & the possibility of life on a planet without water!
Meeting assets for Seager HM with Dr. Sara Seager, Sept. 10, 2025
Dr. Seager focused on a groundbreaking discovery of an ionic liquid compound that could potentially support life on planets without water, made accidentally during research for a Venus space mission. The discussion explored the scientific implications of this discovery, including its potential to expand our understanding of habitable zones and life beyond Earth, while highlighting ongoing research and experiments in this area. The conversation concluded with a discussion of space exploration strategies and the announcement of a privately funded mission to Venus scheduled for 2026, which will investigate cloud particles and ionic liquids.
Professor Sarah Seeger from MIT was welcomed to Hotel Mars to discuss a recent discovery about a planet without water that may be able to sustain life. David noted that this discovery was unexpected and not widely publicized. The conversation began with introductions and background information about Professor Seeger's role at MIT, focusing on planetary science.
Dr Seager discussed the discovery of an ionic liquid compound in a laboratory setting that could potentially exist on planets. He explained that this liquid, held together by ionic bonds, has a very low vapor pressure and doesn't evaporate easily, making it a promising candidate for supporting life beyond water. The discovery was made accidentally by her postdoc while working on a Venus space mission project where they were trying to collect and evaporate sulfuric acid cloud particles to search for signs of life.
Our guest discussed the concept of recognizing life beyond Earth, particularly focusing on ionic liquids as potential habitats for life on planets where water cannot exist. He explained that while biomolecules are stable in ionic liquids, no planets with such conditions have been found yet, making this part of a long-term research journey. David noted that the current habitable zone model needs refinement with adjectives like "water habitable" or "ionic liquid habitable" zone, and mentioned ongoing experiments in his lab that could be replicated by others. She also discussed the possibility of ionic liquids existing below Venus's clouds, though more research is needed to confirm this possibility.
Sara discussed the concept of ionic liquids as potential life-preserving agents in space, particularly in the context of panspermia theory. He explored the possibility of finding ionic fluids on Earth, including in ocean vents and volcanic areas, and considered their potential to sustain life beyond water. The discussion highlighted that while these substances could last for millions of years in space, they might be vulnerable to high-energy particles. The conversation concluded with a note about needed further research on ionic fluids and their potential discovery on planets.
Sarah discussed her vision for space exploration with an unlimited budget, proposing two approaches: sample return missions from solar system planets, and the development of Solar Gravitational Lens Telescopes for distant planet observation. She emphasized the importance of studying Venus's atmosphere as a more practical near-term goal, leading to the formation of the Morningstar missions consortium. She announced a privately funded Rocket Lab mission to Venus scheduled for 2026, which will investigate cloud particles and ionic liquids, noting that this mission is sponsored by Schmidt Sciences and built by Rocket Lab.
