Abstract
Abstract
Characterisation analyses were carried out on several available lunar and Martian simulants in order to provide standardised comparative data to guide testing. Thermal conductivity measurements were performed on regolith powder under ambient conditions Reflectance spectra were obtained for several simulants including separated size-fractions in order to calculate solar absorptance (αS
) values. The change in thermo-optical properties of optical solar reflectors (OSRs) due to lunar simulant EAC-1A <100 μm fraction dust deposition was investigated, showing a linear increase in αS
and infrared emittance (εIR
) values. Facilities are in development for future work involving dusty testing under simulated lunar environments.
