The environment on the lunar surface poses some difficult challenges to building long-term lunar bases; therefore, scientists and engineers have proposed the creation of habitats using lunar building materials. These materials must meet the following conditions: be resistant to severe lunar temperature cycles, be stable in a vacuum environment, have minimal water requirements, and be sourced fr...

More than 130 lunar meteorites have been found in Antarc-tica and other arid regions throughout the world. Even though nearly half of all lunar meteorites are paired falls and the location from which they were launched is unknown, they sample a more extensive area of lunar crust than manned sample returns, thereby providing a vital record of lunar crust materials. To use lunar meteorites to exp...

Introduction: Understanding the origin and evolution of planets remains a major challenge since direct interrogation of planetary interiors other than Earth is either limited or not (yet) available. Seismic analyses provide the most detailed picture of present-day internal elastic structure and sources of seismic energy, but collecting seismic data represents a unique logistical challenge which...

The Moon was thought to be anhydrous since the Apollo era1, but this view has been challenged by detections of water on the lunar surface2–4 and in volcanic rocks5–9 and regolith10. Part of this water is thought to have been brought through solarwind implantation2–4,7,10 and meteorite impacts2,3,7,11, long after the primary lunar crust formed from the cooling magma ocean12,13. Here we show that...

The article, " Are Children Like Werewolves? Full Moon and Its Association with Sleep and Activity Behaviors in an International Sample of Children " by Chaput et al. (1) was quite fascinating and thought-provoking. However, there is a potential flaw in their research – and perhaps in all the medical literature on this subject. Curiously, the study found a small but measurable difference in sle...

Lunar samples are not readily available for In-Situ Resource Utilization (ISRU) studies, necessary for preparations for a return to the Moon with landers, robots, and astronauts. Lunar soil simulants have been produced as substitutes for the real thing; BUT how good are they? JSC-1 and 1A were produced only to approximate the geotechnical properties of lunar soil, with its natural glassy compon...

Background: Osteoporosis is one of the most common problems in the women, especially after menopause and at the old age. Bone densitometry of vertebrae of lumbar region and femoral neck is a non invasive and precise method for evaluation of bone mass density (BMD) and determination of fracture risk. Materials and Method: from different districts of Ahvaz city, more than 300 healthy men and wo...

Low estimated lunar volatile contents, compared with Earth, are a fundamental observation for Earth-Moon system formation and lunar evolution. Here we present zinc isotope and abundance data for lunar crustal rocks to constrain the abundance of volatiles during the final stages of lunar differentiation. We find that ferroan anorthosites are isotopically heterogeneous, with some samples exhibiti...

the chronobiology of the acute myocardial infarction (ami) is an interesting matter for recognition of the biological mechanism that might trigger ami. the present study was aimed to investigate the circadian, seasonal and circannual variation of the ami occurrence with solar, lunar, and christian months. a retrospective study of 1174 cases with diagnosis of ami was conducted. all cases include...

Introduction: Spectroscopic observations (400-670 nm) of Mercury were made at La Palma with the Nordic Optical Telescope (NOT) in June and July of 2002. Extensive observations of solar analog standard stars and validation spectra of 7 Iris and a variety of locations on the Moon were also collected. The 2002 Mercury data were also combined with previous observations (520-970 nm) from the Swedish...
