Lunar Impact Crater Identification and Age Estimation with Chang’E
ARTICLE https://doi.org/10.1038/s41467-020-20215-y OPEN Lunar impact crater identification and age estimation with Chang’E data by deep and transfer learning ✉ Chen Yang 1,2 , Haishi Zhao 3, Lorenzo Bruzzone4, Jon Atli Benediktsson 5, Yanchun Liang3, Bin Liu 2, ✉ ✉ Xingguo Zeng 2, Renchu Guan 3 , Chunlai Li 2 & Ziyuan Ouyang1,2 1234567890():,; Impact craters, which can be considered the lunar equivalent of fossils, are the most dominant lunar surface features and record the history of the Solar System. We address the problem of automatic crater detection and age estimation. From initially small numbers of recognized craters and dated craters, i.e., 7895 and 1411, respectively, we progressively identify new craters and estimate their ages with Chang’E data and stratigraphic information by transfer learning using deep neural networks. This results in the identification of 109,956 new craters, which is more than a dozen times greater than the initial number of recognized craters. The formation systems of 18,996 newly detected craters larger than 8 km are esti- mated. Here, a new lunar crater database for the mid- and low-latitude regions of the Moon is derived and distributed to the planetary community together with the related data analysis. 1 College of Earth Sciences, Jilin University, 130061 Changchun, China. 2 Key Laboratory of Lunar and Deep Space Exploration, National Astronomical Observatories, Chinese Academy of Sciences, 100101 Beijing, China. 3 Key Laboratory of Symbol Computation and Knowledge Engineering of Ministry of Education, College of Computer Science and Technology, Jilin University, 130012 Changchun, China. 4 Department of Information Engineering and Computer ✉ Science, University of Trento, I-38122 Trento, Italy. -

Fought on 30 July 1864, during the Siege of Petersburg, the Battle of the Crater, according to the National Park Service, is one of the most important events of the Civil War. The participation of African-American troops in the battle and the subsequent execution of black prisoners highlights the racial animosities that were the underpinning causes of this conflict. The goal of this project is to document the level of integrity of any archaeological resources connected with this field of conflict and to examine how far the Union troops advance beyond the mouth of the Crater. -

A 1 Case-PR/ }*Rciofft.;Is Report
.A 1 case-PR/ }*rciofft.;is Report (a) This eruption site on Mauna Loa Volcano was the main source of the voluminous lavas that flowed two- thirds of the distance to the town of Hilo (20 km). In the interior of the lava fountains, the white-orange color indicates maximum temperatures of about 1120°C; deeper orange in both the fountains and flows reflects decreasing temperatures (<1100°C) at edges and the surface. (b) High winds swept the exposed ridges, and the filter cannister was changed in the shelter of a p^hoehoc (lava) ridge to protect the sample from gas contamination. (c) Because of the high temperatures and acid gases, special clothing and equipment was necessary to protect the eyes. nose, lungs, and skin. Safety features included military flight suits of nonflammable fabric, fuil-face respirators that are equipped with dual acidic gas filters (purple attachments), hard hats, heavy, thick-soled boots, and protective gloves. We used portable radios to keep in touch with the Hawaii Volcano Observatory, where the area's seismic activity was monitored continuously. (d) Spatter activity in the Pu'u O Vent during the January 1984 eruption of Kilauea Volcano. Magma visible in the circular conduit oscillated in a piston-like fashion; spatter was ejected to heights of 1 to 10 m. During this activity, we sampled gases continuously for 5 hours at the west edge. Cover photo: This aerial view of Kilauea Volcano was taken in April 1984 during overflights to collect gas samples from the plume. The bluish portion of the gas plume contained a far higher density of fine-grained scoria (ash). -
Petrogenes1.S of Apollo 11 Basalts and Implications
PETROGENES1.S OF APOLLO 11 BASALTS AND IMPLICATIONS FOR LUNAR ORIGIN A, E. Rinqwood Department of Geophysics and Geochemistry Australian National University Canberra ABSTRACT The origin of Apollo 11 basalts is discussed in terms of two hypotheses: (i) formation by a small degree of partial melting in the lunar interior and (ii) formation by prolonged near-surface crystallization differentiation in a lava lake. The second hypoth- esis is rejected on the following grounds: Most Apollo 11 magmas are far removed from the plagioclase-pyroxene-ilmenite cotectic; fractional crystallization cannot explain the large variations in concentrations of incompatible trace elehents in conjunction with the small variations in major element compositions, particularly, _IMg ratios; experimentally determined partition coefficients show Fe Pack3 that the high abundances of Cr and V in Apollo 11 cannot be reconciled A with the previous separation of large quantities of ore minerals and pyroxenes. On the other hand, the major element and trace element jq contents of Apollo 11 rocks can be explained by partial melting of sovvromaterial which buffers the major element compositions and causes enrichments of incompatible elements according to the degree of partial melting( fiisk hypbthesis) Two alternative sources have been suggested for Apollo 11 basalts formed by partial melting: (i) unfractionated pyroxenite source region at depths of 200-600 km, (ii) fractionated source region with incompatible elements (e-g. Ba, U, rare 'earths) strongly enriched over chondritic abundances and containing plagioclase (approximate eucritic composition). Mass balance calculations'and plagioclase stability conditions show that the second hypothesis requires Apollo 1l.basalts to be generated by partial melting in the outer 150 km of the moon. -
