Way back in 1976, NASA’s Viking landers touched down on Mars to search for potential signs of microbial life that could currently exist on the planet’s surface. Despite the mission making a number of promising discoveries, so far, no further landers have returned to the surface of the Red Planet with the aim of repeating these fascinating experiments. As such, many questions still remain as to what organisms, if any, could potentially be living within the Martian soil.
In this episode, we’re joined by astrobiochemist and author Steven A. Benner to talk about his latest book, Meet the Neighbours – Life on Mars and How to Find it.
He talks us through some of the scientific debates surrounding the Viking data that continue to this day, tells us how our knowledge of the evolution of life on Earth informs our search for life elsewhere in the Solar System, and explains how recent innovations in the democratisation of spacecraft technology may reignite our search for life on Mars.

Sometimes, no matter how busy we are or how hard we work, when we look back on our day, it can seem like we didn’t really achieve very much. Why is this and what can we do to make more effective use of our time? Could the answer be simply tuning into our bodies’ and minds’ natural rhythms – more specifically the ultradian rhythm, the 90-minute cycles of attention and alertness that oscillate throughout the day?
For many of us, maths is simply a subject we studied at school to help us learn how to count, add one thing to another, and carry out everyday tasks such as managing our personal finances. But if we look more deeply, maths has underpinned the way that humans understand and interpret the world for thousands of years. Without our knowledge of maths, we’d have no smartphones and no internet, our buildings wouldn’t stay standing up, and we’d know very little about the wider Universe we live in.
For those of us who live in towns and cities, bogs may seem to be a rare environmental relic left over from times gone by, or perhaps something we’ve only encountered onscreen in spooky fantasy movies. The fact is that these peat-rich, often otherworldly landscapes are found in almost every corner of the globe, have had a deep influence on the development of human culture, and act as one of the planet’s unsung heroes in the fight against climate change.
From the neatly curated English country garden to the wild jungles of the Amazon, the Earth is host to a staggeringly diverse range of plant life. One of the key reasons for the great evolutionary success of plants is the wide-ranging versatility and utility of the leaves that grow on them.
Every built environment we spend our time in, our homes, offices, music venues or sports stadiums – is designed and constructed after hours of consideration about form and function. Oftentimes, less consideration is given to the impact this has on the health of the planet.
