Density of Molten “ Apollo 17 Orange Glass ”
Introduction: Modelling the dynamic evolution of the interior of the Moon is intrinsically linked to the density of lunar materials at high pressures and temperatures. Lunar magma density variations during crystallisation of the lunar magma ocean are particularly important, since the formation of plagioclase-rich highland rocks and mare basalts are related to density differences between lunar m...
متن کاملMagnetic Properties of Unique Apollo 17 Soil 70051
Introduction: Lunar dust, the <20 μm portion of the Moon’s regolith, posed several unanticipated problems during the Apollo Missions. With our plans for returning humans to the Moon, it is paramount to address these issues. For example, an embarrassing problem involved the fact that none of the ‘Milliondollars rock boxes’ built at Oak Ridge National Lab remained sealed at the vacuum of the Moon...
متن کاملPhotoelectric Emission Measurements on Apollo 17 Lunar Dust Grains:
Introduction: The deleterious effects of the ubiquitous presence of small micron/sub-micron size dust grains in the lunar surface environment are recognized to be one of the major issues that must be addressed in planning the forthcoming missions for robotic and human exploration of the Moon. On theoretical considerations as well as observational evidence, it has been well accepted since the Ap...
متن کاملThe Geologic Investigation of the Taurus-littrow Valley: Apollo 17 Landing Site
Astronauts Cernan and Schmitt, of Apollo 17, landed in the Taurus-Littrow valley of the Moon on December 11,1972. Their major objectives were (1) to sample very ancient lunar material such as might be found in pre-Imbrian highlands as distant as possible from the Imbrium basin and (2) to sample pyroclastic materials that had been interpreted as significantly younger than the mare basalts return...
