Onsite radar shows what lies beneath In more active periods of the Moon's history, volcanic eruptions created lava plains that formed layers dark basalt. Without subsurface probing, we can only examine most recent flows. After soft landing Chang'E-3 spacecraft, Xiao et al. made penetrating measurements lunar crust with Yutu rover. Several suggest multiple geologic processes at play throughout crustal including flows and weathering-induced creation dust rocky debris. Science , this issue p. 1226
Abstract Von Kármán crater (diameter = ~186 km), lying in the northwestern South Pole‐Aitken (SPA) basin, was formed pre‐Nectarian. The floor subsequently flooded with one or several generations of mare basalts during Imbrian period. Numerous subsequent impact craters surrounding region delivered ejecta to floor, together forming a rich sample SPA basin and farside geologic history. We studied details targeted landing (45.0–46.0°S, 176.4–178.8°E) 2018 Chinese lunar mission Chang'E‐4, within...
Abstract The Rümker region (41–45°N, 49–69°W) is located in northern Oceanus Procellarum of the Moon. Mons most distinctive geological feature area. characterized by prolonged lunar volcanism (Late Imbrian Period to Eratosthenian Period), forming multiple geologic units area, including very low‐Ti mare basalts, high‐Ti and volcanic complexes. Each unit has distinct element composition mineral assemblages. region, overlying KREEP Terrain, was selected as landing for China's Chang'E‐5 sample...
Decades of research using remotely sensed data have extracted evidence for the presence an ocean in northern lowlands Mars Hesperian (∼3.3 Ga), but these claims remained controversial due to lack situ analysis associated geologic unit, Vastitas Borealis Formation (VBF). The Tianwen-1/Zhurong rover was targeted land within VBF near its southern margin and has traversed almost 2 km southward toward interpreted shoreline. We report here on first that reveals sedimentary structures features...
Low-altitude mobility, exemplified by unmanned aerial vehicles (UAVs), has introduced transformative advancements across various domains, like transportation, logistics, and agriculture. Leveraging flexible perspectives rapid maneuverability, UAVs extend traditional systems' perception action capabilities, garnering widespread attention from academia industry. However, current UAV operations primarily depend on human control, with only limited autonomy in simple scenarios, lack the...
Abstract Chang'E‐5 is China's first lunar sample‐return mission, which will be launched in 2019. Understanding the distribution of rocks and craters candidate landing region important for selecting suitable sites studying surface geology. This paper separately investigates rock abundance crater density region, then provides a joint analysis them, purposes identifying potential hazards safe their geological implications. The results indicate that are mostly concentrated around rocky ejecta...
Abstract We used imaging, laser altimeter and thermal infrared data to map a 0.5 by 0.5° area containing the landing site of Zhurong rover Tianwen‐1 mission. analyzed regional topography thermophysical characteristics, identified characterized cones, impact craters, polygonal troughs, ridges aeolian bedforms. An absolute model age 757 ± 66 Ma was obtained for major unit dominating study area, younger than previous geological mapping results. propose several targets high scientific interest...
Abstract Aqueous activities on Mars have gradually declined since the Noachian (>3.7 Ga). Although water can be stored in subsurface during latest epochs, geomorphological evidence is still limited. In this study, we used situ imaging and spectral data acquired by China's Zhurong rover, as well high‐resolution remote‐sensing data, to investigate transverse aeolian ridges (TARs) landing region of Utopia Planitia. A two‐stage evolutionary scenario TARs proposed polygonal features with...
Abstract The South Pole–Aitken (SPA) basin, located between the Pole and Aitken crater on far side of Moon, is largest confirmed lunar impact structure. pre-Nectarian SPA basin a 2400 × 2050 km elliptical structure centered at 53°S, 191°E, which should have exposed lower crust upper mantle due to enormous excavation depth. Olivine, dominant mineral in Earth’s mantle, has only been identified small localized exposures margins mafic component is, instead, pyroxene. These mineralogical...
Temperature probes onboard the Chang'E-4 (CE-4) spacecraft provide first in situ regolith temperature measurements from far side of Moon. We present these with a customized thermal model and reveal particle size lunar at CE-4 landing site to be ∼15 μm on average over depth, which indicates an immature below surface. In addition, conductive component conductivity is measured as ∼1.53 × 10-3 W m-1 K-1 surface ∼8.48 depth 1 m. The bulk density ∼471 kg m-3 ∼824 upper 30 cm regolith. These...
Transverse aeolian ridges (TARs), a kind of ripple-like landform, are widely distributed on Mars and usually thought to be active within the last ~3 million years. Most them decameter-scale have relatively symmetric traverse profiles, which quite different from typical dunes or ripple forms Mars. Compared with commonly seen dark-toned dunes, TARs high albedos, representing new class bedform unusual formation mechanism special relationships between martian atmosphere sediment circulation....
Abstract Wind‐eroded ridges known as yardangs are common in most arid desert regions on Earth, well other planets, notably the Medusae Fossae Formation (MFF) and Gale Crater Mars. However, formation evolution of these various not understood, which, therefore, requires further studies by more terrestrial analogues. Here we report a detailed investigation yardang fields Qaidam Basin, northeastern Tibetan Plateau, China. Most them distributed northwestern central eastern parts, with dominant...
Abstract Abundant polygonal surface structure (PSS) landforms within the Qaidam Basin, Tibetan Plateau, northwestern China, are considered to be excellent analogues for PSSs on Mars. In this study, we have carried out fieldwork in Dalangtan Playa, a large dried salt lake complemented with laboratory analyses of collected samples. Our study shows that (1) playa can divided into three groups: small (<10 m), medium (10–100 and (>100 m) according their sizes; (2) samples from dominated by...
