The UCF/DSI CI Carbonaceous Chondrite Simulant (also known as UCF/DSI-CI-2) is 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.

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, and is currently available from the CLASS Exolith Lab.
