Money on the Horizon! (Part 3)
Helium-3: High Value-Added, Core Technology System
To make lunar mining of Helium-3 and water resources a reality, here are the specific technological systems currently under the most active development as of 2026, along with the key companies leading these efforts.
These technologies go beyond simple excavation; the core challenge lies in achieving self-sufficiency within the Moon’s extreme environment (vacuum, cryogenic temperatures, and abrasive micro-dust).
1. 🏗️ Core Technological Systems: Lunar Mining Robots and Infrastructure
① Autonomous Mining Rovers
The lunar surface is covered in sharp regolith, causing standard wheels to wear down quickly. Specialized robots are being developed to overcome this:
- RASSOR (Regolith Advanced Surface Systems Operations Robot): A drum-type mining robot being developed by NASA. It uses counter-rotating drums to excavate soil and collect resources without recoil, even in low-gravity environments.
- Micro-Rovers: Hundreds of small robots form a “swarm” to explore vast areas simultaneously and pinpoint resource-rich locations with high precision.
② In-Situ Resource Utilization (ISRU) Systems
Transporting oxygen and fuel from Earth is prohibitively expensive. Therefore, technology to extract resources directly on the Moon is essential:
- Oxygen and Water Extraction: This involves heating regolith to over 1,000°C to separate oxygen or using microwaves to heat South Pole ice to capture water vapor.
- Helium-3 Refinement: When regolith is heated to approximately 600–700°C, adsorbed Helium-3 is released in gaseous form. The core process involves cooling, liquefying, and concentrating this gas.
③ Lunar Power Grid and Communication Infrastructure
- Vertical Solar Panels: Long solar panels are installed vertically on the “Peaks of Eternal Light” at the lunar South Pole to generate power 24/7.
- Wireless Power Transmission: Using lasers or microwaves to beam energy from power stations to mining robots operating at a distance.
2. 🏢 Key Participating Companies and Their Roles
A “Space Economic Ecosystem” has formed, where government agencies and private companies collaborate, centered around the Artemis Accords.

3. ♻️ Technological Alternatives for Sustainability
“Sustainable Mining” technologies are being developed in parallel to minimize damage to the lunar environment.
- Dust Mitigation: Technology that uses static electricity to prevent dust from adhering to robots and equipment, or uses lasers and electromagnetic fields to trap fugitive dust generated during operations.
- 3D Printing Construction: Instead of bringing materials from Earth, mining bases and roads are constructed using 3D printers with lunar regolith as raw material, minimizing the introduction of pollutants.
- Energy Recycling: Heat and gases generated during the mining process are reused within a closed-loop system to prevent leakage into the lunar exosphere.
💡 Conclusion and Outlook
The current technical level has moved past “exploration and sampling” and is entering the “pilot plant (small-scale factory)” construction phase.
Timeline Forecast: Given the pace of technological advancement in 2026, rocket refueling using oxygen and water produced at the lunar South Pole is expected to begin by the early 2030s. By the 2040s, the large-scale transport of Helium-3 back to Earth will reach economic feasibility.
In this process, South Korean companies are expected to play vital roles as key partners in the global supply chain, particularly in the fields of mobility (Hyundai) and communications/satellites (Hanwha).
