Summary

The paper introduces MGS-1, a Mars regolith simulant based on the Rocknest deposit, with detailed characterization of its physical and chemical properties. It highlights improvements over previous simulants and discusses its potential applications and availability. The provided text is a mix of technical content and metadata related to a scientific paper or report. It includes figures, descriptions of materials and methods, and references to data sources. The main focus appears to be on comparing Martian simulants and their spectral properties. The paper introduces MGS-1, a Mars regolith simulant based on Rocknest soil from Gale crater. It details the mineral composition, bulk chemistry, and physical properties of the simulant, comparing it to rover and remote sensing data. The simulant is designed for testing hardware and scientific research, with production methods and mineral recipes published for reproducibility. roduce modest quantities of MGS-1 based simulant and make it available to the community. However, as an open standard the same mineral recipe and methods described below can be used to re-produce MGS-1 and modify it as desired (Section 5.2). 1.1 Previous Mars simulant
