The safety of lunar landing sites directly impacts the success exploration missions. This study develops a data-driven predictive model based on machine learning, focusing engineering to assess suitability and provide insights into key factors feature representations. Six critical were selected as constraints for evaluation: slope, elevation, roughness, hillshade, optical maturity, rock abundance. XGBoost was employed simulate predict characteristics areas Bayesian optimization used...
The samples from lunar farside have great significance for the study of Moon, and even solar system. Chang’e-6 landed successfully on southern mare Apollo basin returned ~2 kg farside. To provide a better understanding background samples, we conducted detailed crater size-frequency distribution (CSFD) measurements in landing region, basin. is divided into western (W region) eastern (E region), then subdivided five subunits (W1, W2, W3, W4, W5) three units (E1, E2, E3), respectively,...
In-situ assembly of three molecular perovskite energetic materials (DAP-2, DAP-4, and DAN-2) with ammonium perchlorate as a core-shell eutectic oxidizer, the performance mechanism HTPB propellant was investigated. This comprehensive study examined thermal decomposition behavior combustion-agglomeration characteristics oxidizers under pressures ranging from 0.1 to 8.0 MPa. Experimental results demonstrated that synthesized exhibited significant redox reactions during combustion within...
We conducted a detailed study using multi-source data to date the mare activity and lobate scarp formation within Jules Verne crater on Moon. In previous studies, has been classified as pre-Nectarian impact crater. Our analysis indicates that it an absolute model age (AMA) of 4.21+0.032 −0.034Ga. After its formation, magmatic intrusion event created floor fractures, followed by two basaltic eruption events—one at 3.4 Ga another 2.6 Ga. Subsequently, around 1.4 billion years ago, lunar...
The permanently shadowed regions of the lunar South Pole have become a key target for international exploration due to their unique scientific value and engineering challenges. In order effectively screen suitable landing zones near Pole, this research proposes comprehensive evaluation method based on self-organizing map (SOM). Using multi-source remote sensing data, classifies analyzes candidate by combining purposes (such as hydrogen abundance, iron oxide gravity anomalies, water ice...
Magnetite is rare on the Moon. The ubiquitous presence of magnetite in lunar soil has been hypothesized previous Apollo Mössbauer spectroscopy and electron spin resonance studies, but there currently no mineralogical evidence to prove it. Here, we report a large number submicroscopic particles embedded within iron-sulfide surface Chang’e-5 glass, with close positive correlation between content TiO 2 surrounding glass. morphology mineralogy grains suggest that these formed via an impact...
Abstract Pure metallic iron is a common component in extraterrestrial samples (e.g., ordinary chondrite, returned lunar samples), and thought to be an indicator of extremely reducing conditions. However, tiny pure (<1 mm) particles are rarely found Howardite–Eucrite–Diogenite meteorites, their formation mechanism on Vesta poorly understood. Sub‐micron sized were identified by transmission electron microscope studies melt pocket the basaltic eucrite meteorite Northwest Africa 11592. Our...
We perform an infrared (IR) spectral and visible morphological study of two young planetary nebulae (YPNe) Hen 2-73 2-96 using archival Spitzer Space Telescope Hubble (HST) observations to understand their dust properties nebular structures. High-resolution HST images these show several bipolar lobes ionised tori in the central regions both objects. The presence multi-lobe structures suggests that formation process is complex. To search for a possible link between sources multipolar...
The main goal of the gamma-ray spectrometer (GRS) onboard Chang'E-1 (CE-1) is to acquire global maps elemental abundances and their distributions on moon, since such will significantly improve our understanding lunar formation evolution. To derive enable research evolution, raw data that are received directly from spacecraft must be converted into time series corrected spectra. correction procedures for CE-1 GRS thoroughly described. processing create spectra described here include channel...
Abstract Basaltic shergottites are the most abundant rock type of Martian meteorites, and pyroxene grains within commonly show a zoned structure. Here, detailed microscopic mineralogical characteristics patchy in basaltic shergottite NWA 12522 were investigated by combination scanning electron microscopy, microprobe, Raman spectroscopy, transmission microscopy. The results that cores have homogeneous Mg# value consist mainly augite pigeonite. By contrast, rim is extremely ferroan can be...
Abstract The dissolution rates of jarosite can constrain the duration aqueous activities on Mars. To date, few studies have considered influences formation pathways and anion substitutions rates. Here, we investigated how (Fe(II)‐oxidation Fe(III)‐forced hydrolysis) incorporation bromide influence K‐jarosite under eight conditions combining T (277 K, 298 323 K) α w (0.35, 0.75 1), except for 277 K−0.35α . results show that are primarily influenced by ‐α conditions. Formation Br contents...
