Simulant Name: HCCL-1 Hydrated Carbonaceous Chondrite Lithologies
Availability: May Be Availabile
Fidelity: Standard
Developed By: University of Calgary
Available From: N/A
Publications: Hildebrand, A. R. et al. (2015), An Asteroid Regolith Simulant For Hydrated Carbonaceous Chondrite Lithologies (HCCL-1). 78th Annual Meeting of the Meteoritical Society, Abstract #5368.

HCCL-1 was developed as a general purpose asteroid simulant based on the Tagish Lake ungrouped C2 meteorite. The goals were to replicate the anticipated density, porosity, strength, elastic and magnetic properties of Bennu in support of the OSIRIS-Rex mission. The simulant was made by mixing its 4 constituent minerals together wet, then drying and crushing to obtain more realistic particle shapes.

The amount of simulant produced and its availability are unknown.
