KTU researchers: traffic jams on the moon?

More than six decades have passed since the first uncrewed Moon landing, and five decades since Neil Armstrong’s “one small step for man, one giant leap for mankind”. A lot has changed since those days when the USA and the Soviet Union were the only countries possessing spaceflight capacities. In fact, the Moon has become quite a busy place.

In May 2023, the moon lander Hakuto-R, operated by the Japanese company ispace, crashed on the lunar surface after a sensor malfunction. In August, the Russian Luna-25 crashed while attempting a landing on the Moon’s South pole. A few days later, Chandrayaan-3 pulled off a successful landing on the South Pole for the first time in history, putting India on the map as a major new space power.

The Japan Aerospace Exploration Agency launched their newest moon lander this month. China, the USA, and various private organizations are planning further missions to the Moon during this year and the next. And in 2025, the USA will send the first human crew to the Moon in decades, using technology developed by Elon Musk’s SpaceX.

For states, the exploration of the Moon is a matter of power and prestige. For private companies, it is likely extraordinarily profitable. At the same time, new and complex questions arise as lunar traffic increases.

Safety first

For one, safety is becoming a pressing issue, both for human life in outer space and back here on Earth. The recent Titan disaster, where all passengers of a deep-sea tourist cruise perished (presumably because the vessel owner was cutting corners with safety features) highlights the risks of commercial space tourism, including the trips to the Moon that some companies have recently started offering for well-situated clients.

In November 2022, falling debris from a Chinese Long March rocket led to the brief closure of the entire Spanish airspace. In April 2023, a SpaceX launch in Texas created a vast cloud of dust that likely caused considerable environmental harm in the vicinity, leading to questions about the ability and willingness of US regulatory agencies to keep the industrial giant in check.

With growing traffic between the Earth and the Moon, questions of safety and regulatory oversight will become more urgent.

No jurisdiction – no rules?

There are also broader legal issues at stake. The Moon is technically an area beyond national jurisdiction, meaning that national laws do not apply, and states cannot make territorial claims. But could they extract and own lunar resources, such as ice deposits that could be made into vast reserves of oxygen, water, and hydrogen fuel? Could private companies make property claims where no national legislation exists? And how does international law apply to the lunar activities of both states and private organizations?

The 1967 Outer Space Treaty, for example, requires that exploration and use of space “shall be carried out for the benefit and in the interests of all countries”. With growing commercial interest in space tourism, there is a real need to clarify which space-based activities serve greater human needs and which would be no more than a fancy pastime for billionaires.

Avoiding a galactic dumping ground

As space agencies and private companies keep crashing their landers into the Moon, we should also start to think more carefully about the lunar environment. A massive cloud of junk, from spacecraft and derelict satellites, is already circling the Earth, increasingly posing a threat to spaceflight and the orbital infrastructure.

Nuclear power has been a primary energy source for space vehicles for decades, and questions of reactor safety and safe waste disposal are becoming more urgent as they increase in number.

China and the US both aim to construct permanent bases on the Moon within the coming decade. This likely requires the extraction and utilization of lunar raw materials, such as rocks, as bulk construction materials are simply too expensive to ship from Earth. Drilling and construction work on the moon could easily cause significant environmental harm. The same applies for the commercial extraction of lunar resources, such as precious Rare Earth Elements, which various private companies are currently exploring.

It thus appears prudent to consider effective measures for protecting the Moon and its environment as the common heritage of humanity. After all, since we are close to ruining the Earth’s environment, perhaps we could act a little bit more responsibly with the rest of our solar system.
