Performance of Lunar Regolith Shield under Meteoroid Impact: Uncertainties of a Numerical Prediction

Applied Sciences, 2022
The protection of the future lunar base from radiation, thermal stresses and impacts of meteoroids can be achieved by several options, generally consisting in a shielding system, made of either regolith or combined materials.

The Potential for Lunar and Martian Regolith Simulants to Sustain Plant Growth: A Multidisciplinary Overview

Frontiers in Astronomy and Space Sciences, 2022
Bioregenerative life support systems (BLSS) are conceived of and developed so as to provide food sources for crewed missions to the Moon or Mars. The in situ resource utilization (ISRU) approach aims to reduce terrestrial input into a BLSS by using ...

Crop growth and viability of seeds on Mars and Moon soil simulants

Open Agriculture, 2019
If humans are going to establish a base on the Moon or on Mars they will have to grow their own crops. An option is to use Lunar and Martian regolith. These regoliths are not available for plant growth experiments, therefore NASA has developed regolith ...

Calibration of discrete element method simulation parameters for lunar rover using simulated lunar soil

Journal of Physics: Conference Series
Abstract To ensure the accuracy and scientific validity of simulation results in discrete element simulation of simulated lunar soil and sieve wheels for lunar surface probes, a method for calibrating the simulation parameters of an analog lunar soil simulation using a box-Behnken experimental design is proposed.
