Science, 1970
Sixty-one of 1676 lunar rock fragments examined were found to be anorthosites, markedly different in composition, color, and specific gravity from mare basalts and soil breccias. Compositional similarity to Tycho ejecta analyzed by Surveyor 7 suggests that the anorthosites are samples of highlands material, thrown to Tranquillity Base by cratering ...

Science, 1968
Mature meanders in lunar sinuous rills strongly suggests that the rills are features of surface erosion by water. Such erosion could occur under a pressurizing ice cover in the absence of a lunar atmosphere. Water, outgassed from the lunar interior and trapped beneath a layer of permafrost, could be released by a meteoritic impact and overflow the ...

Human Factors: The Journal of the Human Factors and Ergonomics Society, 1969
The purpose of this study was to examine the combined effects of simulated lunar environmental variables on human performance. A facility was developed to simulate the following aspects of the astronaut's lunar environment: confinement within a lunar shelter habitat with an oxygen-enriched atmosphere, high-risk vacuum, ⅙ g., lunar “terrain ...

Lunar Beagle and Lunar Astrobiology
Earth, Moon, and Planets, 2010The study of the elements and molecules of astrobiological interest on the Moon can be made with the Gas Analysis Package (GAP) and associated instruments developed for the Beagle 2 Mars Express Payload. The permanently shadowed polar regions of the Moon may offer a unique location for the “cold-trapping” of the light elements (i.e.

Endeavour, 2007
A close associate of the Lunar Society, Joseph Wright of Derby painted several industrial and scientific scenes. This article (part of the Science in the Industrial Revolution series) shows how two of his works - featuring an orrery and an alchemist - reveal the ideas and aspirations of the provincial philosophers who made up the Society.

Lunar penetrator program: LUNAR-A
Acta Astronautica, 1996Abstract LUNAR-A is to be launched in 1997 for the investigation of the origin and the evolution of the Moon. Each of three penetrators boarded comprises of the seismometer and the heat-flux-meter as the scientific instrument, and the data recorder, transmitter, battery etc. as the common instrument.

Lunar Gravity: Preliminary Estimates from Lunar Orbiter
Science, 1968Tracking data from the lunar orbiters have been analyzed for information regarding Moon's gravity field. These preliminary results include values of a set of harmonic coefficients through degree 4 in the tesserals and degree 8 in the zonals. Implications regarding Moon's mass distribution are discussed: one implication is that Moon is nearly ...

Lunar Features and Lunar Problems
Geological Society of America Bulletin, 1961The major features of the Moon (marcs, highlands, craters, fractures) are briefly reviewed to encourage geologists to participate in the solution of lunar problems—problems involving the interpretation of varied land forms, the rock types and their distribution, potential ore deposits, and lunar tectonics.
