L-TAG is a document developed by the Lunar Thermal Environments Task Team (L-TETT) in 2020 - 2021 to provide guidance to the thermal community regarding thermal analysis assessments of the Lunar natural environments. L-TAG was the first User’s Guide produced under the Human Landing System (HLS) Program. Document number = HLS-UG-001.
11 Ιουν 2019 · To understand how heat flows through particulate material in the lunar regolith, we will review the mechanisms of heat transfer in solids and then consider regolith particles as conglomerates of solid constituents.
11 Ιαν 2020 · The relevant thermophysical properties of lunar surface are thermal conductivity, thermal diffusivity, and specific heat. Since heat flow is a function of thermal conductivity and temperature gradient of a medium, heat flow is also used as an indicator of the thermophysical behavior of the medium.
6 Δεκ 2013 · Here we explore how new measurements (topography, gravity, temperature, and radiogenic distribution) can be combined with three-dimensional heat conduction models to aid in deconvolving the nature of lunar heat flow.
The lunar surface material (regolith or “lunar soil”) is a complex mixture of five basic particle types: crystalline rock fragments, mineral fragments, breccias, agglutinates, and glasses. The relative proportion of each particle type varies from place to place and is dependent on the mineralogy of the
2.4 - Understand the structure and origin of the principal naked-eye lunar surface formations, including: e - valleys. Valleys are long depressions on the Moon's surface. They are difficult to find with the naked eye. Although they can reach hundreds of kilometres long, they are usually only a few kilometres wide.
29 Σεπ 2021 · A standard lunar thermal model (a slightly modified version of Hayne et al., 2017) is used to find new thermal conductivity model parameters that best fit Diviner data. In this paper, we first summarize the relevant physical theories that describe solid heat transfer mechanisms at low temperatures.
