The space industry presents a monumental challenge for civilization, requiring not only technological advancement but also comprehensive legal frameworks. Since the 1967 Outer Space Treaty, nations have agreed that space and celestial bodies are not subject to national sovereignty, military use is prohibited, and space is open for exploration by all countries. However, these treaties largely overlook the role of private companies and individuals in space exploration and exploitation. This legal ambiguity raises questions about the conditions under which governments should enable private ventures and the responsibilities such companies should bear, as humanity contemplates mining the Moon, establishing bases on Mars, or extracting resources from the asteroid belt.
The emerging concept of Space 4.0 reflects a new era where governments, private industry, society, and politics collaboratively drive space activities, akin to Industry 4.0 on Earth. The European Space Agency’s Space 4.0i protocol embodies this vision by promoting innovation, citizen engagement, inspiration, and international partnerships, striving to balance entrepreneurial ambitions with public benefits. Despite a growing space economy—Spain’s industry alone generates 800 million euros annually—the sector remains nascent compared to future prospects like space mining, solar energy capture, and orbital tourism. A significant challenge ahead is managing space debris, requiring sustainable practices such as debris reduction, rocket reuse, and recycling to prevent pollution and ensure the long-term viability of space activities.
Regulating the uses of space is one of the biggest challenges facing the space industry, in part because the agreements approved in the middle of the last century did not provide for this industry.
“Space is easy, it’s empty!” shouted the protagonist of a science fiction film in which they needed to send a ship to the Earth’s core. And while it’s true that propelling yourself with a rocket upwards is easier than tunneling downwards, the reality is that The space industry remains a challenge of a civilization-level caliber. Starting with the fact that space must be legislated.
Space does not belong to any state, but any company can exploit it
In 1967, a couple of years before Neil Armstrong placed the American flag on the Moon, the ‘Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodies’ came into force, thanks to which the countries agreed, among other pacts:
- Space could be explored and used by all states.
- Celestial bodies cannot be claimed by nations.
- They cannot be used for military purposes.
Subsequent treaties with even more signatories have proposed similar agreements, but all of them leave a key use of space out of the scope of the agreement: What about individuals or private companies that want to launch exploration and exploitation missions? International laws rarely contemplate this use of space and, when they do, they are ambiguous or permissive.
In theory, a company could go to the moon, mine helium-3 (3He) and bring it back to Earth to market as nuclear fuel for clean fusion reactors. Or it could reach Mars, look for a comfortable cave and build a planetary base (if it solves some problems such as the lack of atmosphere, the lack of gravity or the lack of magnetic field, among others). It would also be possible to mine minerals from the asteroid belt between Mars and Jupiter, locating a base of operations on Ceres.
This, of course, begs the question: under what conditions should governments facilitate access to space for private companies? What should be demanded of them in return? And what will be the role of space agencies?
Space 4.0, how it seeks to promote the commercialization of space from the public-private agreement
One of the paradigms that has the most pull is the conceptualization of Space 4.0. If Space 1.0 was the early study of astronomy; 2.0 nations exploring near-Earth space (including the Moon) or Venus and Mars; and 3.0 was the one that helped consolidate the International Space Station by uniting the United States, Europe, Russia, Canada and Japan; The Space 4.0 consists of the integration between governments, the private sector, society and politics, as was already the case in Industry 4.0 on the surface of the planet.
When the European Space Agency integrates the Space 4.0 vision into European humanist and legal values, it comes across the Space 4.0i protocol:
- ESA Innovates, through more disruptive technologies that take risks.
- ESA Informa, through the strengthening of the link with agents such as citizens.
- ESA inspires, by launching new initiatives and programmes, to both current and future generations.
- ESA interacts through enhanced partnerships with Member States, European institutions, international actors and industrial partners.
ESA’s vision 4.0 integrates the entrepreneurial spirit of the West, but establishing obligations for companies; and moderates the role of states in Asian societies. It pursues a kind of Goldilocks Zone in which business opportunities are integrated and that these respond to benefit citizens.
The take-off of the space industry, and the problem of space debris
As can be read in the special Future Trends Forum ‘Commercialisation of Space‘, the Spanish space industry (fifth in Europe) has a turnover of 800 million euros per year. This in an economic environment not exactly characterized by high growth and within a sector in which the industry is not yet consolidated.
In essence, the space industry is almost non-existent, compared to future developments in mining on other bodies in the Solar System, solar capture in space, factories and tourism in orbit, travel between planets, etc. Humanity has explored space only with its eyes. Without the need to enter the field of fantasy, science fiction helped to establish a path that the liberalization of space has helped to accelerate and begin to travel.
Although this path is not without risks, as more satellites and probes are sent off the planet, space junk grows. That is why one of the biggest challenges for the industry will be what to do with all space debris, how to pollute space less, how to reuse rockets or how, if it cannot be reduced or reused, how to recycle that waste.
