Multispectral Earth Polarization Observation Based on the Lagrange L1 Point of the Earth–Moon System

Applied Sciences
We propose a Multispectral Earth Polarization Imager (MEPI), which is located at the Earth–Moon system’s Lagrange point L1. The imager can be used to measure the sunlight reflected by the Earth and the Moon.

S/W Development of High Precesion EPHEMERIS(I) [PDF]

Journal of Astronomy and Space Sciences, 1993
We developed the S/W which calculate the Planetary and the Moon ephemerides. The ephemeris of the Solar system objects was obtained from a simultaneous numerical integration of the equations of motion for the nine planets and the Moon.

Expanding Ecotheology to Embrace the Earth-Moon System

Theology and Science, 2022
An enlarged purview for amplification of religious doctrine can become necessary for a spacefaring species. Settlement of distant planetary bodies involves both technological and theological issues. The authors apply this notion to environmental preservation of the Earth, Earth's Moon, and cislunar space between Earth and Moon, as a unit.

Spectral‐Kinetic Synergy in Au‐Network Engineered FeTiO3: A Multi‐Field Coupling Strategy for Lunar In Situ Resource Utilization

Advanced Science, EarlyView.
How can humanity achieve lunar self‐sufficiency? We utilize Au topology networks to modify the abundant lunar ilmenite. This catalyst, under sunlight, can convert waste carbon dioxide into space fuel. This design leverages the moon's natural vacuum for green manufacturing, avoiding the waste of gold and serving as “artificial chloroplasts” to sustain ...

The Limited Role of the Streaming Instability during Moon and Exomoon Formation

The Planetary Science Journal
It is generally accepted that the Moon accreted from the disk formed by an impact between the proto-Earth and impactor, but its details are highly debated.

Optimal Transfers from the L1 Halo Orbit of the Earth–Moon System to Earth

Space: Science & Technology
Designing direct-return orbits from the Earth–Moon space to Earth’s surface is critical for manned lunar missions and emergency returns. This paper investigates optimal transfer solutions from a halo orbit around the Earth–Moon L1 libration point to an ...

RNA Promotes Synapsin Condensates That Organize Synaptic Vesicles in Live Neurons and Enable Localized Translation in Reconstituted System

Advanced Science, EarlyView.
Condensates at synapses organize synaptic vesicles (SVs) and are crucial for efficient neurotransmitter release, yet how RNA contributes to this mesoscale architecture remains poorly understood. Here we uncover that RNA modulates synapsin–driven condensates.

Calculation of a Dynamical Substitute for the Real Earth–Moon System Based on Hamiltonian Analysis

The Astrophysical Journal
The Earth–Moon libration points no longer exhibit the dynamical characteristics of “equilibrium points” due to perturbation effects when applying the ephemeris model. By decoupling the forced motions within the ephemeris model and computing the dynamical

How common are Earth–Moon planetary systems? [PDF]

Icarus, 2010
AbstractThe Earth's comparatively massive moon, formed via a giant impact on the proto-Earth, has played an important role in the development of life on our planet. Here we study how frequently Earth-Moon planetary systems occur. We derive limits on the collision parameters that may guarantee the formation of a circumplanetary disk after a protoplanet ...

3D Printed Meter‐Scale Soft Origami Robots Capable of Load‐Bearing Actuation Via Crease Stiffness Modulation

Advanced Science, EarlyView.
Origami has inspired numerous soft deployable mechanisms for safe human‐robot interaction, while its intrinsic kinematic instability at arbitrary configurations limited their practical robotic application. This work presents a 3D printed meter‐scale origami robotic actuator capable of load‐bearing deformation through creaseline stiffness modulation.
