Mining for essential metals like copper, cobalt, and platinum to meet the demand of the electronics industry is becoming increasingly challenging. As these metals are vital components of everyday objects such as cars, cellphones, computers, and televisions, companies are searching for new sources to meet the growing demand. Scientists propose that thousands of miles beneath Earth’s surface, in its molten core, there is a potential abundance of these metals. However, mining at such extreme depths and temperatures is impractical.
To overcome this challenge, some companies are turning their attention to asteroids. Although the commercialization of asteroid mining is still in its early stages, NASA launched a scientific mission in October 2023 with the aim of exploring the metal-rich asteroid Psyche. By studying the composition and structure of Psyche, scientists hope to gain insights into Earth’s core due to the possibility of similar makeup.
As a planetary geologist, I am particularly excited about the Psyche mission. It provides us with a unique opportunity to directly observe and analyze a piece of a planetary core, something we have not been able to do before. The data collected from this mission will not only benefit scientists studying the formation and evolution of planetary bodies but also contribute to the research into the feasibility of asteroid mining.
Asteroids come in various sizes and compositions. Psyche, for example, is primarily composed of metals and may have originated from collisions during the formation of the solar system. Exploring the surface of Psyche will provide valuable information about the type and quantity of metals present, as well as the potential minerals containing these metals.
While the technology and infrastructure required for asteroid mining are still under development, several companies are already considering the best approaches and lowest-cost strategies. The process would involve identifying mineable metal deposits, drilling and extracting the metals remotely, and transporting them back to Earth via spacecraft. This endeavor would require substantial funding and present logistical challenges.
Although the exact impact of asteroid mining on the global economy is uncertain, there is a possibility that a sudden influx of valuable metals could flood the market and decrease their values. Nevertheless, the Psyche mission marks a significant step in understanding the composition of asteroids and shedding light on the composition and properties of Earth’s core.
