Rotating space habitats can simulate gravity and are a potential solution for creating livable habitats in space.
Terraforming planets may not be practical in the near future, and the focus is shifting towards self-sustainable space habitats.
Artificial Intelligence (AI) plays a crucial role in future space exploration, including assisting in space habitats and managing space debris.

Advancement in Artificial Gravity
The future of space exploration and tourism depends on our ability to develop practical artificial gravity. Rotating space habitats are seen as a viable option to simulate gravity, with smaller rings spinning faster and larger rings rotating more slowly. Currently, launch costs are viewed as the main hurdle to space travel, but reusable rockets like SpaceX's Falcon 9 have significantly brought down costs. In the near future, space travel is expected to become more affordable and accessible for everyday people.
Challenges of Terraforming
While the concept of terraforming other planets is intriguing, it might not be practical in the near future. Mars, for example, lacks a magnetic field to protect its atmosphere and would require constant replenishment. Additionally, the focus is shifting towards creating self-sustainable space habitats rather than transforming entire planets. However, there is ongoing research on developing technology for capturing space debris and mitigating the risks they pose to space travel.
The Role of AI in Space Exploration
Artificial Intelligence (AI) plays a significant role in future space exploration. AI agents could serve as assistants in space habitats, providing support and enhancing human-machine interaction. However, it is essential to ensure that AI remains under human control to prevent unintended consequences. Human-in-the-loop mechanisms and safety controls are crucial to maintain a balance between AI assistance and human decision-making. AI can also assist in managing and mitigating space debris, as well as enhancing various aspects of space exploration and colonization.
Protecting Earth and Future Space Habitats
While there are plans to address space debris and the environmental impact of space travel, protecting Earth should remain a priority. It is crucial to preserve and care for our own planet, as there is currently no viable substitute. Efforts are being made to clean up space debris, including concepts like capturing debris with a space cup or using robotic systems to remove and mitigate potential threats. Balancing space exploration with environmental responsibility is a key consideration for the future of space travel.
The Vision of Future Space Habitats
Future space habitats aim to provide a richly envisioned and diverse society in space. Different jobs and roles will be needed, including doctors, lawyers, comedians, and entertainers. The goal is to create a holistic and thriving community in space that encompasses various professions and talents. The importance of STEM fields should be emphasized, but a balanced view of the future should also include the arts, entertainment, and other essential elements for a fulfilling life in space.
When will we create a livable habitat in space? Neil deGrasse Tyson and Matt Kirshen explore the possibilities of tessellated space structures, artificial gravity, and other challenges with Founder of MIT Space Exploration Initiative, Ariel Ekblaw.
