Beyond being Earth's natural satellite, the Moon holds rare resources, like helium-3, that could potentially revolutionize future fusion energy.
More so, scientists believe that below its cratered surface lie rare earth elements and water ice vital for sustainable space exploration. This endeavor, involving nations and the private sector, is an exploration and a fierce race to uncover the Moon's mysteries.

Mining Lunar Wealth for Sustainable Exploration
Dr. Dimitra Atri, an astrophysicist at New York University Abu Dhabi, emphasized the potential of mining on the Moon's surface in securing resources crucial for technological advancement. He highlighted the Moon's capacity to provide access to rare earth elements essential for manufacturing smartphones and medical equipment, as well as titanium for aerospace and medical applications.
Additionally, the lunar surface's presence of precious metals like gold and platinum opens new possibilities, with the extraction of helium-3 standing out as a promising, rare isotope for clean and efficient nuclear fuel.
However, gaining access to the Moon's untapped resources may take time, as both technological and legal developments for lunar mining are ongoing. NASA's Artemis program aims to explore lunar resources, eventually using them as a launch point for Mars missions.
China, through its Chang'e missions and lunar sample return with Chang'e-5, actively explores the Moon, focusing on the lunar south pole for its water ice deposits and continuous sunlight, strategic for long-term human presence and resource access.
Mojtaba Akhavan-Tafti from the University of Michigan highlighted the Moon's potential as a launch pad for sustainable space operations, citing water as a crucial resource for rocket fuel. NASA's interest in the lunar poles, rich in water ice, aligns with the goal of reducing costs and making space exploration more sustainable.
Gordon Osinski, a planetary geologist at Western University in Canada, emphasized water as the "most important" Moon resource, supporting life, enabling sustainable space operations, and reducing launch costs due to the Moon's lower gravity. Building infrastructure on the Moon could facilitate space hardware manufacturing and resource extraction, making it an ideal location for deep space missions.
Possible Elements Humans Can Mine on the Moon
Teams from China, Israel, India, and NASA, along with private companies like Moon Express, are vying for lunar resources, pushing us closer to potential Moon mining. Below are the possible elements that scientists can mine on the lunar surface:
- Silicon- constituting 20% of moon dirt, could be mined and refined by future lunar settlers to create solar panels for powering outposts.
- Rare Earth Elements (REEs)- essential for tech like hybrid car batteries, are scarce on Earth but could be abundant on the moon, particularly in areas rich in potassium and phosphorus.
- Titanium- found in the dark spots of the moon, makes up to 8 percent of lunar dirt and could be a valuable resource for building materials.
- Aluminum- present in the whiter lunar highlands, constitutes 10 to 18 percent of regolith and can be used in construction, aircraft, and medical devices.
- Water- potentially present in shadowed lunar poles, could offer a significant water source for settlers, serving both drinking and farming needs, and potentially serving as fuel for Mars-bound rockets if split into hydrogen and oxygen.
- Helium-3- a potential fuel for future safe nuclear reactions, is present in small quantities in lunar regolith, with higher concentrations in specific lunar regions like the Sea of Tranquility.
- Other Precious Metals, like platinum-group elements, are known for their conductivity and nonreactivity, making them ideal for electronics and medical implants.
