The living tech we need to support human life on other planets | Lynn Rothschild

TL;DR

In this TED Talk, Lynn Rothschild proposes using life as a technology to solve the challenges of human settlement off planet.

Transcript

Translator: Joseph Geni Reviewer: Joanna Pietrulewicz For thousands of years, well, really probably millions of years, our ancestors have looked up at the sky and wondered what's up there, and they've also started to wonder, hmm, could we be alone in this planet? Now, I'm fortunate that I get to get paid to actually ask some of those questions, and... Read More

Key Insights

• 🌌 Our ancestors have always wondered if we are alone in the universe and the speaker is fortunate to explore those questions and find answers with taxpayer funding.
• 🌍 As humans venture into space, they will need to be independent and find solutions to various needs, such as transportation, life support, food, clothing, oxygen, power, heat, light, and radiation protection.
• 🚀 The cost of sending supplies to space is expensive, and there is a need to minimize mass and find storage solutions to ensure astronauts are prepared and self-sufficient.
• 🍄 Life itself can be seen as a technology that provides solutions. By using organisms and their capabilities, such as creating biomaterials, it is possible to address the challenges faced in space exploration.
• 🏰 Fungal mycelium can be used to create habitats on Mars. By growing mycelium in structures and adding water after landing, it is possible to create a sustainable habitat while minimizing upmass.
• 💻 Digital information can be sent as DNA sequences, which can be synthesized and incorporated into organisms to provide new capabilities.
• 🔬 Biology can also be used as a means to extract metals, create electrical energy, and explore the possibility of creating organisms with unique capabilities.
• 🌱 Synthetic biology allows for the manipulation and tweaking of organisms to adapt to extreme environments, which is crucial for off-planet human settlement and understanding life in the universe.

Questions & Answers

Q: What is the main topic of the video?

The main topic of the video is the potential use of biology and life as a technology to help humans colonize other planets, particularly Mars.

Q: What are some of the challenges that need to be addressed in order to establish human settlements off planet?

Some of the challenges include the need for transportation, life support, oxygen, gravity adaptation, habitats, power, heat, light, radiation protection, and the issue of upmass, which refers to the cost and mass associated with launching materials into space.

Q: How does the speaker propose to address the upmass problem?

The speaker proposes using biological organisms, specifically Bacillus subtilis spores, to serve as a platform for designing and producing biomaterials needed for human settlements in space. By leveraging the capabilities of biology, it may be possible to reduce the need for launching heavy and prebuilt structures.

Q: What is the speaker's opinion on tinkering with life?

The speaker believes that tinkering with life through synthetic biology is not only necessary but also beneficial. Humans have been genetically modifying organisms for thousands of years, and synthetic biology offers a new approach to solving problems and advancing technology.

Summary & Key Takeaways

• The speaker discusses the need for technology to help humans inhabit and explore other planets.

• The speaker proposes using life itself as a technology, specifically exploring the use of organisms and synthetic biology.

• The speaker suggests that this approach could solve the challenges of mass, storage, and reliability in space exploration.
