Introduction: Before establishing a human outpost on the Moon, numerous problems associated with lunar dust must be addressed and mitigated [1, 2]. The deleterious nature of lunar dusts was experienced during all Apollo missions. Lunar dusts (brought in on dirty spacesuits and boots) contaminated the atmosphere in the lunar module and irritated the eyes, sinuses, and throats of the astronauts [...

Introduction: The lunar mare basalts potentially provide a unique sample suite for understanding the nature of basalts on the martian surface. Our current knowledge of the mineralogical and chemical composition of the basaltic material on Mars comes from studies of the basaltic martian meteorites and from orbital and surface remote sensing observations. Petrographic observations of basaltic mar...

One of the oqtical datasets for optimal selection of future lunar lana_ng sites is local, to regional-scale topography. Lunar base site selection will require such data for hoth engineering and scientific olX,rations purposes. The Lunar Geosctence Orbiter or Lunar Obsert_or is the ideal precursory science mission from which to obtain this required information. We suggest that a simple laser alt...

A global scheme of Lunar-Earth Information Network is proposed in this paper. It is composed of a lunar-earth Messenger, a lunar Orbiter and a Lunar Probe net, through which an information collection and communication network is formed. Moreover, the triune exploration and project features are described in detail. Keyword: LunarNet, Messenger, Orbiter, Lunar Probes

Personal characteristics of patients and environmental factors at psychiatric hospitals have been identified as predictors of absconding. This study seeks to establish a relationship between time of the year and absconding. All characteristics of absconders were analysed over a two-year period using hospital records (N= 104). Public holidays and lunar phases were obtained through almanacs for e...

Findings:Román, Soriano, Fuentes, Gálvez, and Fernández (2004) suggested that the number of hospital admissions related to gastrointestinal bleeding was somehow influenced by the phases of the Earth’s moon. Specifically, the authors claimed that the rate of hospital admissions to their bleeding unit is higher during the full moon than at other times. Their report contains a number of methodolog...

Introduction: Highly refractory micro-minerals such as zircon, monazite and baddeleyite can survive and record intense shock metamorphism, and occasionally recrystallize to date impact events. Their microscale records have the potential to be used to deduce the timing and magnitude of large impacts in ex-situ solar system samples (i.e. meteorites, crystal clasts in breccias) provided we have a ...

across) and UI-21 (1.5 cm across). UI-3 is a websterite, composed of augite (gray), orthopyroxene (white) and spinel (brown); at the top is the host basalt. UI-21 is a spinel lherzolite; spinel is brown, other phases near-white. MINERALOGY DETERMINATIONS BY CHEMIN XRD, TESTED ON ULTRAMAFIC ROCKS (MANTLE XENOLITHS). A. H. Treiman, K. L. Robinson, D. F.

Water uptake of seeds of Phaseolus vulgaris L. cv Limburg was monitored in a controlled atmosphere every day at solar noon for a period of 2 years. The imbibition rate, determined as the mean of five replicas, was related to the lunar cycle, maximal water uptake occurring between the new phases of the cycle. The monthly mean value of imbibition rate, calculated from the daily measurements, disp...
