Planetary Simulant Database

The UCF Planetary Simulant Database maintains up-to-date information on currently available and historic planetary simulants. If you would like a simulant added to the database, or can provide missing information, please email Kevin Cannon (cannon@ucf.edu). Note that we do not keep physical samples of simulants in the database, but we distribute our own simulants through the CLASS Exolith Lab. In partnership with the ESA Sample Analogue Curation Facility, we also offer complimentary consulting on all simulant-related matters.

The listing of simulants below was last updated on September 16, 2018.

Simulants are categorized by the planetary body and their general type. Those marked in green are known to be currently available. Those marked in yellow are either under development or recently produced, and may be available in small quantities from the developers.

We also maintain a downloadable spreadsheet (.xlsx) with a listing of the simulants and their bulk chemistry where available.

Simulant categories

General purpose: A simulant designed to match multiple properties (chemical, mineralogical, geotechnical) of the reference material. We do not count ground-up terrestrial rocks as general purpose simulants unless they are augmented to be more realistic, or if the developers make the case that the mineralogy is a good match to the reference material.

Geotechnical: A simulant designed mostly to replicate geotechnical properties, with little effort to achieve accurate mineralogy or chemistry.

Spectral: A simulant designed primarily to match the reflectance or emission spectra of a reference material.

Magnetic: A simulant designed to replicate the magnetic properties of a reference material.

Unknown: Not enough information available to classify the simulant.
