Endospore Integrity And Viability Of Bacillus subtilis On Simulated Martian Regolith In Rotational UVC Radiation Exposures
Current understanding of Martian regolith has advanced due to various rover explorations. Due to this, there are now several variants of Martian regolith that are chemically known and commercially available.
