Thermal state of the Moon at age 100 Ma. [1] Having a mean density of 3,346.4 kg/m 3, [2] the Moon is a differentiated body, being composed of a geochemically distinct crust, mantle, and planetary core. This structure is believed to have resulted from the fractional crystallization of a magma ocean shortly after its formation about 4.5 billion ...
Science fiction in which robot R. Daneel Olivaw is depicted living inside a partially hollow Moon. [49] David Weber, Mutineers' Moon (1991). Science fiction in which the Moon is a giant spaceship, which arrived 50,000 years ago. [50] Moonfall (2022). Science fiction film portraying the Moon as a Dyson sphere enclosing a white dwarf. [51]
Moon's internal structure: solid inner core (iron-metallic), molten outer core, hardened mantle and crust. The crust on the Moon's near side permanently facing Earth is thinner, featuring larger areas flooded by material of the once molten mantle forming today's lunar mare.
This new discovery has found the “hidden” structures at depths of about 300m (984ft). The new data suggests the first 130ft under the lunar surface is made up of layers of dust, soil, and rocks.
Inside, a lightweight pressurized inflatable with the same dome shape would be the living environment for the first human Moon settlers." [ 64 ] The building technology would include mixing lunar material with magnesium oxide , which would turn the "moonstuff into a pulp that can be sprayed to form the block" when a binding salt is applied that ...
[1] [2] Potential lunar resources may encompass processable materials such as volatiles and minerals, along with geologic structures such as lava tubes that, together, might enable lunar habitation. The use of resources on the Moon may provide a means of reducing the cost and risk of lunar exploration and beyond. [3] [4] [5]
Geological studies of the Moon are based on a combination of Earth-based telescope observations, measurements from orbiting spacecraft, lunar samples, and geophysical data. . Six locations were sampled directly during the crewed Apollo program landings from 1969 to 1972, which returned 382 kilograms (842 lb) of lunar rock and lunar soil to Earth [8] In addition, three robotic Soviet Luna ...
On Artemis missions, a trip to the Moon (scheduled for 2025) and eventually Mars will require a stopover at the Lunar Gateway, a space station that will support a sustainable human presence on the ...
