Introduction: In order to make use of the flood of data on the Moon’s gravity and topography provided by missions such as Lunar Reconnaissance Orbiter and GRAIL [1] to constrain our understanding of the Moon’s internal structure, we have been developing a comprehensive database of lunar rock densities and porosities [2]. This database includes contributions from both lunar meteorites and sample...
Apollo Legacy: Samples collected during the Apollo era suggest impact bombardment of the lunar surface was particularly intense early in solar system history [1]. Argon-Ar isotopic analyses of Apollo samples suggested three to possibly six of the immense impact basins on the nearside were produced between 3.88 and 4.05 Ga [2]. Additional U-Pb and Rb-Sr analyses of Apollo samples suggested the e...
Introduction: Whereas previous experimental studies [1,2,3] and interpretation of Apollo seismic experiments [4,5] are permissive for garnet in the deep lunar mantle, interpretations of Lu-Hf isotopic systematics [6] and trace element data [7] seem to require garnet in the source of selected mare basalts. Understanding the mineralogy of the deep lunar mantle is critical to our further interpret...
Using the full wave approach, the quasi specular contributors to the scattered fields from the large scale surface roughness as well as the Bragg-like diffusely scattered fields from the small scale surface roughness are accounted for in a unified self-consistent manner. Thus the full wave computer codes for the scattering cross sections contain ground truth data only. It has been shown how the...
Introduction: The key to significant lunar science and exploration return lies in supplying the crews on the surface with a robust EVA capability. This capability should include high mobility pressure garments; tactile, dexterous gloves; reduced overhead in preparing for and recovering from EVAs; management of regolith contamination; and control of suit leakage to prevent planetary contaminatio...
After examining the flight pattern of Parnassius apollo males we have discovered that the patrolling strategy of that species can be divided into two modes – random flights exhibited when females were abundant and there was limited time for flight (bad weather conditions), and scanning flights when the population was sparse and favourable climatic conditions allowed undisrupted flight. Accordin...
Introduction: Glass spherules in lunar soils are formed by meteoroid impacts on the lunar surface, though some are believed to be due to volcanic firefountaining events [1]. We recently reported [2] the ages of 155 lunar spherules from Apollo 14 soil sample 14163, determined by the Ar/Ar isochron technique. These spherules are all inferred to have been formed in impacts, and, since the sample w...
The name of Rodogune was not applied only to the well known statuette Aphrodite Anadyomene from Parthian Nisa, but also a seal impressed on sealing Nisa Square House. Although attribution seal, unlike that statuette, discussed in detail, portrait depicted it recognized as Arsacid princess. Actually, head is female, male, and can all likelihood be Apollo with laurel wreath. style execution sugge...
Plato’s Phaedo aims to restore the reputation of Socrates by transforming him from a political scapegoat Athens hero city who had put death. As scholars have shown, dialogue’s heroization shares affinities with religious tradition cult (see White, 2000; Nagy, 2015). In this article I argue that conceptualization philosopher as is developed further in Republic and Laws. The presents “oikist” ide...
