Limitations and Hazards of Space Settlement
Space settlement poses challenges due to potential radiation exposure, psychological impacts, and microgravity effects on the human body. The long-term consequences of radiation exposure in space are not well understood, and living in partial gravity can have negative effects on bones and muscles. The psychological challenges of being in space for extended periods, along with communication delays, can also impact mental health. Additionally, the feasibility of space settlement is challenged by the high costs and technological requirements for long-term sustainable habitats.
Various Locations for Space Settlement
In terms of potential locations for space settlement, Mercury is too hot and difficult to reach, while Venus's extreme conditions make it unsuitable. The Moon, with its low gravity, temperature variations, and limited resources, poses challenges for long-term settlement, while Mars is the most feasible option due to its gravity and available resources. Other locations, such as the asteroid belt and gas planets, are less suitable or inaccessible for settlement.
Competition for Limited Resources
The scarcity of desirable locations for space settlement creates competition among nations and organizations. Specific areas like lunar lava tubes and the polar craters with water resources on the Moon are considered prime real estate. The ambiguity of property rights in outer space, as outlined in the Outer Space Treaty, leads to debates about the legality of resource extraction and commercial activities. The Moon Treaty attempted to clarify these issues but failed due to lack of major participant support. The recent Artemis Accords, a non-binding agreement led by the United States, highlights safety zones and the U.S.'s interpretation of resource extraction rights in space.
Implications and Concerns
The focus on limited premium locations and different interpretations of property rights in outer space raise concerns about potential conflicts and lack of regulation. The push for space settlement by major spacefaring nations like the U.S. and China, along with national interests and economic considerations, further complicates the legal landscape. The need for clear guidelines on resource utilization, safety zones, and international cooperation becomes increasingly important to ensure peaceful and ethical space exploration and settlement.
The Importance of a Plan B
One of the main arguments for space settlement is the need for a plan B, a backup for humanity in case something happens to Earth.
The Challenges of Permanent Settlement
Creating a self-sustaining settlement on Mars is a long way off due to technological and biological constraints. It is crucial to ensure that pursuing a plan B planet does not harm Earth in the process.
The Benefits of Exploration and Legal Development
While permanent settlement may pose challenges, there are other exciting aspects of space travel and exploration that can be pursued. Short-term missions for exploration can be rewarding, and there is ample opportunity to further develop international law and regulations for space activities.
Outer space is back in style. For the first time in decades, NASA is sending astronauts back to the moon. Millionaires are exiting the atmosphere on a regular basis. And Elon Musk says humans may land on Mars to set up settlements by 2030. But would mastering space be worth it?
In their new book, “A City on Mars,” co-authors (and spouses) Dr. Kelly and Zach Weinersmith argue that it’s probably not. From biology to engineering to international law, they charmingly survey the many charms and dangers that space inevitably entails, with pictures to boot. For this week’s Chatter episode, Scott R. Anderson spoke with Kelly and Zach about their book, what role they think space exploration and settlement should play in humanity’s future, and why space may not be all it’s cracked up to be anytime soon.
