Optimization of mechanical strength of biocemented Martian regolith simulant soil columns

نویسندگان

چکیده

Biocemented Martian regolith simulant (MRS) columns were developed using a microalga, Thraustochytrium striatum. Response surface methodology was used to maximize the unconfined compressive strength (UCS) of biocemented MRS towards particle size, cell biomass loading, and nutrient (CaCl2/urea) loading. Overall, UCS increased with increase loading while medium size achieved highest UCS. But didn’t show consistent effect. The maximum reached 603.83 kPa 0.25 ? 0.425 mm 3.8 g/100 mL 5.83 CaCl2 14.18 urea

Mojave Martian Simulant: a New Martian Soil Simulant

Introduction: The development of the next generation of Martian missions requires a suitable simulant that best represents dust and soils that exists on the Martian surface so engineering and scientific studies can be preformed in terrestrial laboratories. The current Mars simulant of choice is JSC MARS-1 soil simulant, developed in 1998, which is the <1mm size fraction of altered volcanic ash ...

JMSS-1: a new Martian soil simulant

It is important to develop Martian soil simulants that can be used in Mars exploration programs and Mars research. A new Martian soil simulant, called Jining Martian Soil Simulant (JMSS-1), was developed at the Lunar and Planetary Science Research Center at the Institute of Geochemistry, Chinese Academy of Sciences. The raw materials of JMSS-1 are Jining basalt and Fe oxides (magnetite and hema...
