Key Questions of Earth Wind–Moon Interaction

Space: Science & Technology
The Moon is exposed to a variety of complex space environments during its 29.5-d orbiting around Earth, of which one-quarter in Earth’s magnetosphere. The collection of particles in Earth’s magnetosphere is called Earth wind, which consists of the solar ...

Evolution of the Earth-Moon system

The Astronomical Journal, 1994
The tidal evolution of the Earth-Moon system is reexamined. Several models of tidal friction are first compared in an averaged Hamiltonian formulation of the dynamics. With one of these models, full integrations of the tidally evolving Earth-Moon system are carried out in the complete, fully interacting, and chaotically evolving planetary system ...

Polar Orbits around the Newly Formed Earth–Moon Binary System

The Astrophysical Journal
We examine the dynamics and stability of circumbinary particles orbiting around the Earth–Moon binary system. The moon formed close to the Earth (semimajor axis a _EM ≈ 3 R _⊕ ) and expanded through tides to its current day semimajor axis ( a _EM = 60 R ...

Simulation Study of Geometric Characteristics and Coverage for Moon-Based Earth Observation in the Electro-Optical Region

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2017
Large-scale geoscience phenomena are increasingly attracting more attention because of their great scientific and social significance. However, many existing earth observation systems lack the ability to conduct long-term continuous observations at a ...

A Systematic Survey of Moon-forming Giant Impacts. I. Nonrotating Bodies

The Astrophysical Journal, 2023
In the leading theory of lunar formation, known as the giant impact hypothesis, a collision between two planet-size objects resulted in a young Earth surrounded by a circumplanetary debris disk from which the Moon later accreted.

Deformation‐Tolerant Functional Elastomer Overlayers for Haze‐Assisted Light Extraction and Color Conversion in Stretchable Mechanoluminescent Films

Advanced Functional Materials, EarlyView.
Functional elastomer overlayers are integrated onto stretchable ZnS:Cu‐PDMS mechanoluminescent films to regulate light after emission without modifying the emissive composite. NLC‐PU provides haze‐assisted light extraction to enhance green mechanoluminescence, while DCM‐NLC‐PU combines green‐to‐yellow‐orange color conversion with enhanced outward light

Photocatalytic Water Splitting on the Lunar Surface: Prospects for In Situ Resource Utilization

Advanced Materials Interfaces, EarlyView.
Water has been found in craters on the moon nearby locations which are illuminated >80% of the time. Photocatalysis uses energy from sunlight to drive chemical reactions such as water splitting to produce oxygen and hydrogen. It is a scalable technology that requires lighter equipment and utilizes resources available on the moon. ABSTRACT The discovery

Earth’s Rapid Rotation and Magma Ocean Solidification Drastically Limit Angular Momentum Removal by the Evection Resonance After a High-angular-momentum Moon-forming Giant Impact

The Astrophysical Journal
Moon formation by a high-angular-momentum (high-AM) giant impact may be best able to explain Earth–Moon isotopic similarities. However, the excess AM must be subsequently removed for consistency with the Earth–Moon system.

A Cryopreservation‐Based Supply Chain Strategy for Extrusion Bioprinting in Space

Advanced Materials Technologies, EarlyView.
Extrusion bioprinting on crewed space platforms requires a bioink that stays functional along the logistic chain. Here, cells and biomaterial ink travel separately, the cells cryopreserved and the ink cold stored, and are combined only minutes before printing.

Plaid‐Like Spin Splitting and Chirality of Magnon Bands in Antiferromagnetic MnTe2

Advanced Science, EarlyView.
Helicity‐ and angle‐resolved Raman spectroscopy reveals chiral magnons in the non‐coplanar antiferromagnet MnTe 2. Combined with first‐principles calculations and spin‐wave theory, the results establish its altermagnetic character through circular Raman dichroism, reduced rotational symmetry, and a distinctive plaid‐like momentum‐space magnon spin ...
