Simulant Name: UCF/DSI CI v1 prototype (UCF/DSI-CI-1)
Current Status: No longer available
Developed By: UCF & Deep Space Industries
Available From: N/A
Publications: DSI Spec Sheet

The UCF/DSI CI v1 prototype was a general purpose asteroid regolith simulant based on the Orgueil CI carbonaceous chondrite. The mineralogy is based on the analysis by Bland et al. 2004. Version 1 had higher elemental fidelity, but the updated version 2 is an improved mineralogical simulant.

To produce the simulant, individual mineral components are sourced and prepared, then mixed together with water to physically bind them. The resulting mixture is dried to remove the water, then mechanically ground in a rock crusher to achieve the desired particle size distribution.

The simulant was produced as part of a NASA SBIR grant to create realistic asteroid simulants.
