Private citizens and companies may one day begin to permanently settle outer space and celestial bodies. But if we don’t enact governing laws in the meantime, space settlers may face legal chaos.

Many wars on Earth start over territorial disputes. In order to avoid such disputes in outer space, nations should consider enacting national laws that specify the extent of each settler’s authority in outer space and provide a process to resolve conflicts.

I have been researching and writing about space law for over 40 years. Through my work, I’ve studied ways to avoid war and resolve disputes in space.

Property in space

Space is an international area, and companies and individuals are free to land their space objects – including satellites, human-crewed and robotic spacecraft and human-inhabited facilities – on celestial bodies and conduct operations anywhere they please. This includes both outer space and celestial bodies such as the Moon.

The 1967 Outer Space Treaty prohibits territorial claims in outer space and on celestial bodies in order to avoid disputes. But without national laws governing space settlers, a nation might attempt to protect its citizens’ and companies’ interests by withdrawing from the treaty. They could then claim the territory where its citizens have placed their space objects.

Nations enforce territorial claims through military force, which would likely cost money and lives. An alternative to territorial claims, which I’ve been investigating and have come to prefer, would be to enact real property rights that are consistent with the Outer Space Treaty.

Territorial claims can be asserted only by national governments, while property rights apply to private citizens, companies and national governments that own property. A property rights law could specify how much authority settlers have and protect their investments in outer space and on celestial bodies.

The Outer Space Treaty

In 1967, the Outer Space Treaty went into effect. As of January 2025, 115 countries are party to this treaty, including the United States and most nations that have a space program. https://www.youtube.com/embed/NUCZt5OcszY?wmode=transparent&start=0 The Outer Space Treaty is the main international agreement governing outer space. However, it is not self-executing.

The Outer Space Treaty outlines principles for the peaceful exploration and use of outer space and celestial bodies. However, the treaty does not specify how it will apply to the citizens and companies of nations that are parties to the treaty.

For this reason, the Outer Space Treaty is largely not a self-executing treaty. This means U.S. courts cannot apply the terms of the treaty to individual citizens and companies. For that to happen, the United States would need to enact national legislation that explains how the terms of the treaty apply to nongovernmental entities.

One article of the Outer Space Treaty says that participating countries should make sure that all of their citizens’ space activities comply with the treaty’s terms. Another article then gives these nations the authority to enact laws governing their citizens’ and companies’ private space activities.

This is particularly relevant to the U.S., where commercial activity in space is rapidly increasing.

UN Charter

It is important to note that the Outer Space Treaty requires participating nations to comply with international law and the United Nations Charter.

In the U.N. Charter, there are two international law concepts that are relevant to property rights. One is a country’s right to defend itself, and the other is the noninterference principle.

The international law principle of noninterference gives nations the right to exclude others from their space objects and the areas where they have ongoing activity.

But how will nations apply this concept to their private citizens and companies? Do individual people and companies have the right to exclude others in order to prevent interference with their activities? What can they do if a foreign person interferes or causes damage?

The noninterference principle in the U.N. Charter governs relations between nations, not individuals. Consequently, U.S. courts likely wouldn’t enforce the noninterference principle in a case involving two private parties.

So, U.S. citizens and companies do not have the right to exclude others from their space objects and areas of ongoing activity unless the U.S. enacts legislation giving them that right.

US laws and regulations

The United States has recognized the need for more specific laws to govern private space activities. It has sought international support for this effort through the nonbinding Artemis Accords.

As of January 2025, 50 nations have signed the Artemis Accords.

The accords explain how important components of the Outer Space Treaty will apply to private space activities. One section of the accords allows for safety zones, where public and private personnel, equipment and operations are protected from harmful interference by other people. The rights to self-defense and noninterference from the U.N. Charter provide a legal basis for safety zones.

Aside from satellite and rocket-launch regulations, the United States has enacted only a few laws – including the Commercial Space Launch Competitiveness Act of 2015 – to govern private activities in outer space and on celestial bodies.

As part of this act, any U.S. citizen collecting mineral resources in outer space or on celestial bodies has a right to own, transport, use and sell those resources. This act is an example of national legislation that clarifies how the Outer Space Treaty applies to U.S. citizens and companies.

Property rights

Enacting property rights for outer space would make it clear what rights and obligations property owners have and the extent of their authority over their property.

All nations on Earth have a form of property rights in their legal systems. Property rights typically include the rights to possess, control, develop, exclude, enjoy, sell, lease and mortgage properties. Enacting real property rights in space would create a marketplace for buying, selling, renting and mortgaging property.

Because the Outer Space Treaty prohibits territorial claims, space property rights would not necessarily be “land grabs.” Property rights would operate a little differently in space than on Earth.

Property rights in space would have to be based on the authority that the Outer Space Treaty gives to nations. This authority allows them to govern their citizens and their assets by enacting laws and enforcing them in their courts.

Space property rights would include safety zones around property to prevent interference. So, people would have to get the property owner’s permission before entering a safety zone.

If a U.S. property owner were to sell a space property to a foreign citizen or company, the space objects on the property would have to stay on the property or be replaced with the purchaser’s space objects. That would ensure that the owner’s country still has authority over the property.

Also, if someone transferred their space objects to a foreign citizen or company, the buyer would have to change their objects’ international registration, which would give the buyer’s nation authority over the space objects and the surrounding property.

Nations could likely avoid some territorial disputes if they enact real property laws in space that clearly describe how national authority over property changes when it is sold. Enacting property rights could reduce the legal risks for commercial space companies and support the permanent settlement of outer space and celestial bodies.

U.S. property rights law could also contain a reciprocity provision, which would encourage other nations to pass similar laws and allow participating countries to mutually recognize each other’s property rights.

With a reciprocity provision, property rights could support economic development as commercial companies around the world begin to look to outer space as the next big area of economic growth.

State-of-the-art artificial intelligence systems like OpenAI’s ChatGPT, Google’s Gemini and Anthropic’s Claude have captured the public imagination by producing fluent text in multiple languages in response to user prompts. Those companies have also captured headlines with the huge sums they’ve invested to build ever more powerful models.

An AI startup from China, DeepSeek, has upset expectations about how much money is needed to build the latest and greatest AIs. In the process, they’ve cast doubt on the billions of dollars of investment by the big AI players.

I study machine learning. DeepSeek’s disruptive debut comes down not to any stunning technological breakthrough but to a time-honored practice: finding efficiencies. In a field that consumes vast computing resources, that has proved to be significant.

Where the costs are

Developing such powerful AI systems begins with building a large language model. A large language model predicts the next word given previous words. For example, if the beginning of a sentence is “The theory of relativity was discovered by Albert,” a large language model might predict that the next word is “Einstein.” Large language models are trained to become good at such predictions in a process called pretraining.

Pretraining requires a lot of data and computing power. The companies collect data by crawling the web and scanning books. Computing is usually powered by graphics processing units, or GPUs. Why graphics? It turns out that both computer graphics and the artificial neural networks that underlie large language models rely on the same area of mathematics known as linear algebra. Large language models internally store hundreds of billions of numbers called parameters or weights. It is these weights that are modified during pretraining. https://www.youtube.com/embed/MJQIQJYxey4?wmode=transparent&start=0 Large language models consume huge amounts of computing resources, which in turn means lots of energy.

Pretraining is, however, not enough to yield a consumer product like ChatGPT. A pretrained large language model is usually not good at following human instructions. It might also not be aligned with human preferences. For example, it might output harmful or abusive language, both of which are present in text on the web.

The pretrained model therefore usually goes through additional stages of training. One such stage is instruction tuning where the model is shown examples of human instructions and expected responses. After instruction tuning comes a stage called reinforcement learning from human feedback. In this stage, human annotators are shown multiple large language model responses to the same prompt. The annotators are then asked to point out which response they prefer.

It is easy to see how costs add up when building an AI model: hiring top-quality AI talent, building a data center with thousands of GPUs, collecting data for pretraining, and running pretraining on GPUs. Additionally, there are costs involved in data collection and computation in the instruction tuning and reinforcement learning from human feedback stages.

All included, costs for building a cutting edge AI model can soar up to US$100 million. GPU training is a significant component of the total cost.

The expenditure does not stop when the model is ready. When the model is deployed and responds to user prompts, it uses more computation known as test time or inference time compute. Test time compute also needs GPUs. In December 2024, OpenAI announced a new phenomenon they saw with their latest model o1: as test time compute increased, the model got better at logical reasoning tasks such as math olympiad and competitive coding problems.

Slimming down resource consumption

Thus it seemed that the path to building the best AI models in the world was to invest in more computation during both training and inference. But then DeepSeek entered the fray and bucked this trend.

Their V-series models, culminating in the V3 model, used a series of optimizations to make training cutting edge AI models significantly more economical. Their technical report states that it took them less than $6 million dollars to train V3. They admit that this cost does not include costs of hiring the team, doing the research, trying out various ideas and data collection. But $6 million is still an impressively small figure for training a model that rivals leading AI models developed with much higher costs.

The reduction in costs was not due to a single magic bullet. It was a combination of many smart engineering choices including using fewer bits to represent model weights, innovation in the neural network architecture, and reducing communication overhead as data is passed around between GPUs.

It is interesting to note that due to U.S. export restrictions on China, the DeepSeek team did not have access to high performance GPUs like the Nvidia H100. Instead they used Nvidia H800 GPUs, which Nvidia designed to be lower performance so that they comply with U.S. export restrictions. Working with this limitation seems to have unleashed even more ingenuity from the DeepSeek team.

DeepSeek also innovated to make inference cheaper, reducing the cost of running the model. Moreover, they released a model called R1 that is comparable to OpenAI’s o1 model on reasoning tasks.

They released all the model weights for V3 and R1 publicly. Anyone can download and further improve or customize their models. Furthermore, DeepSeek released their models under the permissive MIT license, which allows others to use the models for personal, academic or commercial purposes with minimal restrictions.

Resetting expectations

DeepSeek has fundamentally altered the landscape of large AI models. An open weights model trained economically is now on par with more expensive and closed models that require paid subscription plans.

The research community and the stock market will need some time to adjust to this new reality.
