There’s something both terrifying and oddly comforting about knowing we have four billion years left. The sun will expand, swallow Earth, and explode. We need to leave. The question isn't whether we should go, but how we'll survive once we do.

I’ve always been drawn to stories about humanity’s future in space. Not the sanitized Hollywood versions, but the messy, complicated reality of what it would actually take. When I discovered Dr. Christopher Mason’s book, The Next 500 Years: Engineering Life to Reach New Worlds, I knew I had to talk to him. Here’s a geneticist and computational biologist who’s been a Principal Investigator on 11 NASA missions, laying out an actual roadmap for reengineering ourselves to survive in space.

What followed was a conversation that moved from CRISPR gene editing to exowombs, from the ethics of human enhancement to what life might look like on Mars in 2151. We talked about splitting atoms and landing on moons, about the kind of imagination it takes to see beyond what seems impossible today. This conversation felt like a reminder that the bold ideas that seem like science fiction today become tomorrow’s reality.

In this episode, we discuss:

• The 500-year roadmap for humanity’s survival beyond Earth

• How CRISPR and genetic engineering could adapt us for life in space

• What exowombs are and why they might be necessary on distant worlds

• The ethics of reengineering ourselves and selecting for desirable traits

• Why we have a moral obligation to safeguard life by expanding into space

• What life could look like in 2151: Moon colonies, Mars stations, and beyond

• Dr. Mason’s work on 11 NASA missions and what he’s learned about space biology

• Whether humans are psychologically ready for the isolation of deep space

• How imagination and bold thinking drive scientific progress

• Why we can’t afford to be small-minded about humanity’s future
