The effect of pre-impact spin on the Moon-forming collision [PDF]

Monthly notices of the Royal Astronomical Society, 2020
We simulate the hypothesized collision between the proto-Earth and a Mars-sized impactor that created the Moon. Among the resulting debris disc in some impacts, we find a self-gravitating clump of material.

Moon-tracking orbits using motorized tethers for continuous earth–moon payload exchanges [PDF]

, 2013
For human colonization of the moon to become reality, an efficient and regular means of exchanging resources between the Earth and the moon must be established.

Религиозно-философские мотивы в «Лунном Пьеро» А. Шёнберга: к вопросу о содержательной интерпретации цикла

Вестник музыкальной науки, 2016
Самое известное произведение А. Шёнберга по причине сложности избранных музыкально-языковых средств, содержательной глубине и смысловой многозначности ставит перед исполнителями трудные интерпретаторские задачи.

Lunar Laser Ranging Retroreflectors: Velocity Aberration and Diffraction Pattern

The Planetary Science Journal, 2023
The Lunar Laser Ranging (LLR) retroreflector arrays have been on the Moon for half a century. During that time, the laser range uncertainty has improved by a factor of 100. Consequently, the science results have also improved by orders of magnitude.

Evidence for Transient Atmospheres during Eruptive Outgassing on the Moon [PDF]

The Planetary Science Journal, 2020
Events following the giant impact formation of the Moon are thought to have led to volatile depletion and concurrent mass-dependent fractionation of the isotopes of moderately volatile elements (MVE).

Analytical Model for the Tidal Evolution of the Evection Resonance and the Timing of Resonance Escape

, 2020
A high-angular momentum giant impact with the Earth can produce a Moon with a silicate isotopic composition nearly identical to that of Earth's mantle, consistent with observations of terrestrial and lunar rocks.

Prospects in the orbital and rotational dynamics of the Moon with the advent of sub-centimeter lunar laser ranging [PDF]

, 2007
Lunar Laser Ranging (LLR) measurements are crucial for advanced exploration of the laws of fundamental gravitational physics and geophysics. Current LLR technology allows us to measure distances to the Moon with a precision approaching 1 millimeter.

Mapping of Ice Storage Processes on the Moon with Time-dependent Temperatures

The Planetary Science Journal, 2020
Lunar cold traps are defined by extremely low time-integrated sublimation loss, so that water ice is expected to accumulate in them. Due to the strong dependence of the sublimation rate on temperature, they have heretofore been delineated by the peak ...

Care and support for youth living with HIV/AIDS in secondary schools: perspectives of school stakeholders in western Uganda

BMC Public Health, 2021
Background Although schools have been identified as significant settings in the response to the HIV/AIDS pandemic, limited research is available on how they can accommodate Youth Living with HIV/AIDS (YLWHA), especially in resource limited countries.

The Origin of the Moon Within a Terrestrial Synestia [PDF]

, 2018
The giant impact hypothesis remains the leading theory for lunar origin. However, current models struggle to explain the Moon's composition and isotopic similarity with Earth. Here we present a new lunar origin model.
