OUYANG Ziyuan is a distinguished geologist and cosmochemist, known as the founding father of the Chinese lunar exploration program. In the past two decades, he played a leading role in developing China＇s first lunar probes and blueprinting China＇s lunar exploration roadmap. He worked as chief scientist of the nation＇s first lunar mission, which was carried out by a China-made moon-orbiting spacecraft called Chang＇e-1. For the first time in the Chinese history, Chang＇e-1 accomplished moon observation in lunar orbit for nearly 16 months and obtained 100m-resolution 3D imagery of the entire moon＇s surface. After the success of Chang＇e-1, OUYANG continued to chair the Chang＇e-2 mission, the second lunar orbiter launched by China in 2010 which mapped the entire globe of the Moon in 7m resolution. 相似文献

Studies by astronomers from the CAS Purple Mountain Observatory （PMO） haveoffered solid evidence that Sayh al Uhaymir 300 （SaU 300）, a lunar meteorite discovered in 2004 from the Oman desert, was originated from the far side of the Moon, the lunar hemisphere that is permanently turned away from the Earth. 相似文献

Working with the 200 different phenological cold/ warm records of phenomena and crop distribution extracted from a number of historical documents about places geographically located at latitudes 27°-40°N and longitudes 107°-120°E, the winter half-year temperature （October to April） for the past 2,000 years at 10-30 years＇ time resolution in the central region of eastern China was reconstructed （See Figurel; Ge et al., 2003）, and the climatic periodicity was detected （Ge et al., 2004）. 相似文献

Chang’E-4 landed in the South Pole-Aitken (SPA) basin, providing a unique chance to probe the composition of the lunar interior. Its landing site is located on ejecta strips in Von Kármán crater that possibly originate from the neighboring Finsen crater. A surface rock and the lunar regolith at 10 sites along the rover Yutu-2 track were measured by the onboard Visible and Near-Infrared Imaging Spectrometer in the first three lunar days of mission operations. In situ spectra of the regolith have peak band positions at 1 and 2 μm, similar to the spectral data of Finsen ejecta from the Moon Mineralogy Mapper, which confirms that the regolith''s composition of the landing area is mostly similar to that of Finsen ejecta. The rock spectrum shows similar band peak positions, but stronger absorptions, suggesting relatively fresh exposure. The rock may consist of 38.1 ± 5.4% low-Ca pyroxene, 13.9 ± 5.1% olivine and 48.0 ± 3.1% plagioclase, referred to as olivine-norite. The plagioclase-abundant and olivine-poor modal composition of the rock is inconsistent with the origin of the mantle, but representative of the lunar lower crust. Alternatively, the rock crystallized from the impact-derived melt pool formed by the SPA-impact event via mixing the lunar crust and mantle materials. This scenario is consistent with fast-cooling thermal conditions of a shallow melt pool, indicated by the fine to medium-sized texture (<3 mm) of the rock and the SPA-impact melting model [Icarus 2012; 220: 730–43]. 相似文献

Lunar outpost agriculture 总被引：1，自引：0，他引：1
America's long-term commitment to a new Space Exploration Initiative has focused attention on the basic requirements for establishing a permanently manned lunar outpost and, ultimately, a martian one. High among these is the development of Regenerative Life Support Systems--with lunar agriculture an essential component--to provide a high level of self-sufficiency. 相似文献

The Chinese lunar probe Chang''e-4 (CE-4) landed in the Von Kármán crater within the South Pole–Aitken (SPA) basin on the far-side of the Moon on 3 January 2019. Following this, the moon rover Yutu-2 separated from the CE-4 lander and started its travels and exploration on the far-side of the Moon. Before this landing, humans had remotely observed the far-side of the Moon with lunar satellites. However, it was the first time that a man-made spacecraft had landed there and actually left behind wheel prints belonging to humanity.Since China''s Lunar Exploration Project (CLEP), or Chang''e Project, started in 2004, China has accomplished the first two steps of its three-step plan of ‘Orbiting, Landing and Returning’. CE-3 and CE-4 landed successfully on the near-side and far-side of the Moon, respectively. In the near future, CE-5 will land again on the near-side of the Moon and take lunar rock and soil samples back to Earth, thus completing the three-step plan of CLEP. In April 2019, National Science Review (NSR) interviewed three key figures of CLEP: CLEP Chief Engineer Weiren Wu (), the first CLEP Chief Scientist and CLEP senior consultant Ziyuan Ouyang (), and CLEP third phase Vice-Chief Engineer, CE-4 Ground Research and Application System Director Chunlai Li (). They talked about the scientific expectations and future plans of China''s lunar and deep space exploration. 相似文献
