Colonization of the Moon is the proposed establishment of a permanent human community or robotic industries on the Moon, the closest astronomical body to Earth.. Discovery of water in the soil at the lunar poles by Chandrayaan-1 in –09 renewed interest in the Moon, after NASA missions in the 's suggested the presence of lunar ng a colony at one of the lunar poles would also. Another important physical property of the regolith is the thermal inertia defined as I T = k C v (J m −2 K −1 s-1/2). It measures the ‘resistance’ of the substrate’s temperature to change. The higher the thermal inertia the more energy the regolith .

A lunar based solar thermal power system with regolith thermal storage is presented and the performance analysis is carried out by the finite-time thermodynamics to take into account major irreversible losses. The influence of some key design parameters are analyzed for system optimization.
The main results are summarized as follows: 1)Cited by: Abstract The concept of using lunar regolith as a thermal energy storage medium was evaluated. The concept was examined by mathematically modeling the absorption and transfer of heat by the lunar. Get this from a library. Analysis of lunar regolith thermal energy storage.
[Anthony J Colozza; United States. National Aeronautics and Space Administration.]. The concept of using lunar regolith as a thermal energy storage medium was evaluated. The concept was examined by mathematically modeling the absorption and transfer of heat by the lunar regolith.
Regolith thermal and physical properties were established through various sources as functions of by: The cylindrical analysis was performed in order to examine the amount of energy which can be stored in the regolith throughout a number of lunar day/night cycles.
A constant temperature cylinder was used to heat the regolith during the day. At night the cylinder acted as a perfect insulator. For the long-term operations, the lunar surface is a severe environment because the soil (regolith) temperature varies widely from nighttime − degC to daytime degC approximately in which space electronics can hardly survive.
The MSM has a tent of multi-layered insulators and performs a “regolith mound”. Analysis of the test results determined that sulphur concrete, polymer concrete and sintered lunar soil simulant (all ISRUs) are viable options for thermal energy storage on the both the Earth and the Moon.
The second system studied here is the Thermal Energy Storage (TES), which is able to run a heat engine during the lunar night to produce electricity.
When the Sun is shining on the Moon's surface, the system can run the engine directly using the solar power and simultaneously heat a thermal. In its native state, lunar regolith is a poor material for thermal energy storage. Due to its very low thermal diffusivity, about x m2/s per measurements made during the Apollo program,4heat does not penetrate the lunar surface very deeply and is.
In this paper, the thermal characterization of lunar regolith simulant, sintered using a conventional oven under ambient and vacuum conditions is presented. Additionally, thermal characterization of samples is performed for the parts manufactured using solar, laser, and microwave processing.

Abstract The concept of using lunar regolith as a thermal energy storage medium was evaluated. The concept was examined by mathematically modeling the absorption and transfer of heat by the lunar regolith.
Regolith thermal and physical properties were established through various sources as functions of. American Institute of Aeronautics and Astronautics Sunrise Valley Drive, Suite Reston, VA The use of engineered, Thermal Energy Reservoirs (TERs) is one of several energy -storage options.
While actual lunar regolith is a poor thermal -mass material, it can readily be processed to. Experimental Determination of In Situ Utilization of Lunar Regolith for Thermal Energy Storage A Lunar Thermal Energy from Regolith (LUTHER) experiment has been designed and fabricated at the NASA Lewis Research Center to determine the feasibility of using lunar soil.
Samples are characterized regarding their thermal capacity, thermal diffusivity, density, and thermal conductivity. Furthermore, sample morphology is studied using scanning electron microscopy. Lastly, processing of regolith for lunar thermal energy storage is discussed.
Thermal storage advantage • Compare two energy storage approaches: – 1) launch mass is mainly proportional to stored energy (P*t). - Batteries - Fuel cells – 2) launch mass is mainly proportional to required power - Regolith thermal storage with heat engine • In other words imagine two different systems such that b 1 and a 2 are small.
The thermal property values of the thermal mass are critical to the eectiveness of the thermal wadi. In its native state, lunar regolith is a poor material for thermal energy storage.

Introduction and Background  The Moon experiences extremes in surface temperature due to its slow rotation, lack of atmosphere, and the near‐ubiquitous presence of a highly insulating regolith layer.
Equatorial daytime temperatures reach K, while nighttime temperatures fall below K. Because the subsolar point remains within ∼° of the equator over the lunar year and nodal.

An aerospace engineer has built a machine to make water and oxygen from the lunar regolith, powered by solar energy. Thorsten Denk’s paper Design and Test of a Concentrated Solar Powered Fluidized Bed Reactor for Ilmenite Reduction was presented at the 23rd Annual SolarPACES Conference in Chile.
(Thorsten Denk – Presentation (pdf)Working over a ten year period at the .This paper presents illumination analyses using the latest Earth-based radar digital elevation model (DEM) of the lunar south pole and an independently developed analytical tool. These results enable the optimum sizing of solar/energy storage lunar surface power systems since they quantify the timing and durations of illuminated and shadowed periods.
