Introduction: The New Views of the Moon initiative has integrated remotely sensed and sample data in its approach to synthesizing lunar research over the last 30+ years. This integration has clearly demonstrated what we know and, maybe more importantly, what we don t know about the Moon. Most significantly, it has helped to formulate fundamental scientific questions about the Moon that still ne...

Anorthosites occur ubiquitously within the lunar crust at depths of 3-30 km in apparent confirmation of the Lunar Magma Ocean (LMO) hypothesis [1,5]. We will present recent chronological studies of anorthosites [2] that are relevant both to the LMO hypothesis and also to the lunar cataclysm hypothesis. Old (ca. 4.4 Ga) Sm-Nd ages have been determined for some Apollo 16 anorthosites, and primiti...

Introduction: The Diviner Lunar Radiometer Compositional Investigation will use multichannel (0.3 – 300 μm) spectral observations to constrain the composition of the lunar surface. Diviner will be the first lunar orbiting instrument capable of identifying the Christiansen feature (mid-infrared emissivity maximum), which is a good compositional identifier [1]. Diviner will also be the first inst...

We revisit the early evolution of the Moon’s bombardment. Our work combines modeling (based on plausible projectile sources and their dynamical decay rates) with constraints from the lunar crater record, radiometric ages of the youngest lunar basins, and the abundance of highly siderophile elements in the lunar crust and mantle. We deduce that the evolution of the impact flux did not narrow imp...

Purpose: The Moon is not only the closest and most accessible extraterrestrial frontier. The lunar surface, with its rugged terrain, long diurnal cycle, and wide range of extreme thermal and illumination conditions varying as a function of latitude and local relief, represents a great portion of the entire range of conditions found throughout the solar system. The lunar surface is thus an ideal...

aim and background: suicide is a multifactorial attempt. cultural and religious factors play important roles in its prevention and frequency. moslem societies have various approaches to different months of the year. they also have different ceremonies and customs during each month. we studied the frequency of suicide attempts during different months of lunar calendar along a 10-year period. met...

Future lunar missions ask for the capability to perform precise Guidance, Navigation and Control (GNC) to the selected landing sites on the lunar surface. This paper studies the guidance issues for the lunar pinpoint soft landing problem. The primary contribution of this paper is the design of descent guidance law based on the Pontryagin maximum principle. The simulation shows that the proposed...
