“…According to data provided by manned Apollo lunar missions, lunar soil has very low thermal conductivity, that changes significantly with temperature, bulk density and applied pressure [12,[17][18][19][20][21]23]. Specific heat of lunar regolith is also highly temperature dependent [22].…”

Abstract. This study was performed in order to verify viability of using finite difference method and proposed simple astrometrical model for modelling heat transfer in lunar regolith. The concept was examined by developing FD model of heat flow for upper 0,9 m of lunar regolith, and comparing obtained results with in situ measurements provided by Apollo 15 and 17 heat flow experiments. The model was based on FDM approximation of Fourier's law for one dimensional transient heat flow. Both constant and temperature-dependent thermophysical properties of lunar regolith were obtained from in situ measurements. Thermal boundary conditions were assumed on in situ measurements and on remote sensing based analytical model. In order to approximate Sun's position at lunar sky, simple analytical astrometric model of lunar rotation was developed. Matlab 2012a was used to conduct the calculations. Stable solutions were obtained for latitudes between 0 and 80°. Satisfactory agreement between Apollo 15 and 17 in situ measurements and FDM modelling was observed. A conclusion was reached, that both FDM and proposed astrometrical model are to be successfully applied for modelling heat transfer in lunar regolith.

High T_g Polymer Insulator Yields Organic Photovoltaic Blends with Superior Thermal Stability at 150 ^oC

Main observation and conclusion Record‐breaking organic solar cells (OSCs) based on blends of polymer donors and small molecule acceptors often show undesirable degradation, which severely precludes their practical use. Herein, we demonstrate a facile and cost‐effective approach to construct thermally stable OSCs at 150 oC by incorporating a small amount of a polymer insulator polyacenaphthylene (PAC) with high glass‐transition temperature over 230 oC into polymer:acceptor blends. The model PTB7‐Th:EH‐IDTBR blend with 10 wt% PAC maintained above 85% of its initial efficiency upon continuous heating at 150 oC for over 800 h, while the efficiency of the blend without PAC sharply dropped by 70% after ~300 h. Owing to high miscibility with acceptors, PAC confines the motion of the acceptor molecules and suppresses the acceptor crystallization at elevated temperatures, leading to significantly improved stability. Importantly, the effectiveness of this blending approach was also validated in many other OSC systems, showing great potential for achieving high‐performance thermally stable electronics.

Since the beginning of the new century, the objectives of deep space exploration missions targeting celestial bodies such as the Moon and Mars shift from “understanding celestial bodies” to “utilizing celestial bodies.” With respect to the successful operation of various load missions, secondary battery systems play a crucial role in supplying energy. However, unlike terrestrial environment, extremely harsh extraterrestrial conditions, including extreme temperatures and radiation, severely limit the application of batteries in deep spaces. This work covers recent advancements in batteries, including electrolyte/electrode optimization strategies and thermal management under extreme low‐ and high‐temperature conditions and the mechanism analysis of key battery components under radiation environments. Finally, perspectives are given on the remaining challenges posed by battery applications in extreme deep space environment.
