Phyllosilicatic and Sulfatic Mars Regolith Simulants

← Return to simulant listing

Simulant Name: hyllosilicatic and Sulfatic Mars Regolith Simulants
Availability: May Be Available
Fidelity: Standard
Developed By: German Aerospace Center DLR, Germany
Available From: N/A
Publications: Böttger, U. et al. (2012), Optimizing the detection of carotene in cyanobacteria in a martian regolith analogue with a Raman spectrometer for the ExoMars mission. Planetary and Space Science 60, 356-362.

These two simulants were used to specifically test the Raman Laser Spectrometer (RLS) on the ExoMars rover and its ability to identify organics and minerals. They were meant to represent the environmental chance on Mars from early hydrothermal alteration to later cold and dry oxidizing conditions. The materials were crushed and mixed, then sieved to a <1 mm size fraction for experiments with cyanobacteria.
