Abstract Due to the lack of an atmosphere and a global magnetic field on Moon, its surface is extensively subject space weathering. One important products weathering iron particle, which has significant impacts for planetary exploration. Research Apollo samples suggests that particles primarily form through vapor deposition processes during meteorite impacts. The Chang'e‐5 (CE5) are youngest collected so far, phenomenon not been studied in depth. Anorthite stoichiometrically free Fe...
Chang'E-6 lunar soil was the first sample collected on farside. It provides insights into impact history and thermodynamic evolution of Moon. Here we show discovered widespread oldhamite (CaS) in regolith samples. Analysis microscopic composition crystal structure showed that has a cubic presence at interface glass iron surface beads, suggesting thermochemical reaction. Thermodynamic calculations formation chemical reactions requires reducing atmosphere high temperature to ensure environment...
China's Chang'e-5 spacecraft successfully collected 1731 g of Lunar regolith and returned it to Earth on December 17, 2020. In this paper, simulated is used as the main material form stable dense solid soil structures by adding different amounts an inorganic curing agent water. The internal morphology, failure morphology under uniaxial compression, stress–strain relationship solidified samples (L-R-S-Ss) are then investigated. damage constitutive model cured body analyzed according curves,...
<title>Abstract</title> Understanding the nature and evolution of near-Earth asteroids (NEAs) are paramount importance to planetary science1 security2. So far, three asteroid sample-return missions, Hayabusa, Hayabusa2, OSIRIS-REx have greatly increased our knowledge several-hundred-meter rubble-pile NEAs. However, limited by ground-based observation spatial resolution, little is known about smaller Recently, China National Space Administration has proposed a new mission, Tianwen-2, which...
