Asteroid Mining Prospecting

Asteroid mining prospecting uses robotic spacecraft including cubesats and small landers equipped with spectrometers, imagers, and sampling systems to survey near-Earth asteroids and characterize their composition, identifying valuable resources including water (for propellant and life support), precious metals, and rare earth elements. These prospecting missions create resource catalogs that inform future mining operations and help identify the most valuable targets for extraction.

This innovation addresses the first step in enabling space resource utilization, where understanding what resources are available and where they are located is essential before extraction can begin. By prospecting asteroids, these missions identify valuable targets, assess extraction feasibility, and create the knowledge base needed for commercial mining operations. Companies backed by Luxembourg and other nations, along with NASA missions, are developing these capabilities.

The technology is essential for enabling the space resource economy, where asteroid mining could provide materials for space construction, propellant for deep-space missions, and rare materials for Earth. As prospecting missions succeed and identify valuable targets, they pave the way for commercial mining operations that could transform space economics. However, the technology faces challenges including the cost of prospecting missions, the difficulty of characterizing asteroids remotely, and the long timeline from prospecting to profitable extraction. The technology represents an important first step toward space resource utilization, but significant development is still needed.
