The origin of volatile elements in the Earth-Moon system. [PDF]

open access: yesProc Natl Acad Sci U S A, 2022
Significance Understanding the history of volatile species such as water in the Earth–Moon system is a major objective of planetary science. In this work, we use the moderately volatile element Rb, which has a long-lived isotope ( 87 Rb) that decays to 87

Two Periodic Models for the Earth-Moon System [PDF]

open access: yesFrontiers in Applied Mathematics and Statistics, 2018
This paper discusses two alternative models to the Restricted Three Body Problem (RTBP) for the motion of a massless particle in the Earth-Moon system. These models are the Bicircular Problem (BCP) and the Quasi-Bicircular Problem (QBCP).

Comparison Study of Earth Observation Characteristics between Moon-Based Platform and L1 Point of Earth-Moon System

open access: yesRemote Sensing
The unceasing quest for a profound comprehension of the Earth system propels the continuous evolution of novel methods for Earth observation. Of these, the Lagrange points situated in the cislunar space proffer noteworthy prospects for space-based Earth ...

Effects of the evolving early Moon and Earth magnetospheres

open access: yesFrontiers in Astronomy and Space Sciences, 2023
Recently it has been identified that our Moon had an extensive magnetosphere for several hundred million years soon after it was formed when the Moon was within 20 Earth Radii (RE) from the Earth.

Analysis of Geometric Characteristics and Coverage for Moon-Based/Spaceborne Bistatic SAR Earth Observation

open access: yesRemote Sensing, 2023
With the rapid development of Earth system science, a new understanding of the complete Earth system has highlighted the crucial importance of integrated observations, especially in research involving large-scale geoscience phenomena. As an active sensor

The Trojan Manifold in the System Earth-Moon [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1967
Abstract : The Trojan manifold is defined as the analytical manifold of periodic orbits which contains the triangular equilibrium L4 as a singularity. Identification of the Earth-Moon system is made to a planar Restricted Problem of Three Bodies. The barycentric synodical coordinate system and the units of length, time and mass are chosen as defined by

Results of Long-Duration Simulation of Distant Retrograde Orbits

open access: yesAerospace, 2016
Distant Retrograde Orbits in the Earth–Moon system are gaining in popularity as stable “parking” orbits for various conceptual missions. To investigate the stability of potential Distant Retrograde Orbits, simulations were executed, with propagation ...
