Task-Specific Asteroid Simulants for Ground Testing
Project Description
We will design, prototype, and test a variety of asteroid simulants needed to validate most aspects of asteroid ISRU processes. These include physical simulants for excavation, transfer, and preparation (including comminution); chemical/mineralogical/volatile simulants for processing tests such as volatiles extraction, metals extraction, and oxygen production; and simulants to evaluate scientific and commercial instrumentation. The need for task-specific asteroid simulants is illustrated by the history of ill-designed and ill-applied lunar simulants, and current practices for asteroid simulants, which are marked by ad-hoc improvisation that frequently results in an inability to compare results among experiments or reliably repeat experiments for confirmation.

Anticipated Benefits
Simulants are needed in order to adequately test equipment prior to launch to an actual asteroid. The simulant may need to adequately reproduce the physical characteristics of an asteroid to validate sampling techniques, anchoring methods, or to test hazards such as dust production. A simulant may need to reproduce the appearance and spectrum of an asteroid, in any of several wavelength ranges. It may need to replicate the mineralogy and possibly the volatiles content to test related instrumentation.
Asteroid mining is a new commercial application that begs for appropriate asteroid simulants. Companies such as DSI need to test instrumentation for proximity operations, mineralogical assay, excavation techniques and equipment, volatiles extraction, metals and oxygen production, and hazards (such as dust) mitigation.
