Chapter 28: Review of Planetary Resources and Deep Space Industries’ Approaches

28.1 Introduction

The burgeoning field of asteroid mining has seen significant contributions from private enterprises, particularly Planetary Resources and Deep Space Industries (DSI). These companies were pioneers in conceptualizing and developing commercial strategies for extraterrestrial resource extraction, focusing on technology development, resource identification, and mission planning.

This chapter provides an in-depth review of the approaches adopted by these companies, their technological innovations, mission designs, challenges faced, and their legacy in shaping the asteroid mining industry.

28.2 Planetary Resources: The First Steps in Asteroid Mining

28.2.1 Founding Vision

• Mission: To enable humanity’s expansion into space through asteroid resource utilization.
2. Key Founders:
• Eric Anderson (space entrepreneur) and Peter Diamandis (founder of the XPRIZE Foundation).
3. Core Objectives:
• Prospecting near-Earth asteroids (NEAs) for water and precious metals.
• Developing technologies for resource extraction and processing.

28.2.2 Technological Developments

1. Arkyd Satellite Series:
• Arkyd 100: Low-cost, compact space telescopes for asteroid imaging and spectrometry.
• Arkyd 200: Enhanced capabilities for asteroid reconnaissance.
• Arkyd 300: Designed for prospecting missions with greater autonomy.
2. Innovation in Sensors:
• Optical and infrared systems to detect water and metal signatures.
• Gamma-ray spectrometers for subsurface analysis.
3. Autonomous Operations:
• Developing AI systems to operate without direct human intervention.

28.2.3 Business Strategy

1. Short-Term Goals:
