We analyzed angling catch records for 341,959 muskellunge (Esox masquinongy) from North America to test for a cyclic lunar influence on the catch. Using periodic regression, we showed that the number caught was strongly related to the 29-day lunar cycle, and the effect was consistent across most fisheries. More muskellunge were caught around the full and new moon than at other times. At night, ...

Laboratory analyses of lunar samples provide a direct means to identify indigenous volatiles and have been used to argue for the presence of Earth-like water content in the lunar interior. Some volatile elements, however, have been interpreted as evidence for a bulk lunar mantle that is dry. Here we demonstrate that, for a number of lunar pyroclastic deposits, near-infrared reflectance spectra ...

Introduction: The possible existence of water ice in permanently shadowed regions near the lunar poles has been postulated by Watson et al. [1]. The delivery rate of water into the cold lunar polar craters due to degassing from the lunar interiors, micrometeorite bombardment, solar wind, and comet impacts was investigated [2]. Some experiments have been made to search for the existence of water...

In order to study passing ability of lunar rover in lunar soil, the mechanical parameters between lunar wheel and lunar soil should be analyzed. The mechanical parameters can reflect the mechanical relationship between lunar rover wheel and regolith. These parameters include sinkage, drawbar pull, driving torque, motion resistance and slip. In this paper, these parameters are measured by soil b...

Introduction: SELENE Spectral Profiler (SP) obtains Lunar Visible to NIR spectral data at spatial resolution of 500 m [1]. Since brightness of lunar surface depends on the viewing geometry, we have to correct these data to the values under certain standard observation geometry prior to the detailed analysis by an adequate phase curve. Although many researchers had proposed photo-metric models a...

We present sensitive radio continuum imaging at 1.4 GHz and 4.9 GHz of seven high redshift QSOs selected for having a 240 GHz continuum detection, which is thought to be thermal dust emission. We detect radio continuum emission from four of the sources: BRI 0952−0115, BR 1202−0725, LBQS 1230+1627B, and BRI 1335−0417. The radio source in BR 1202−0725 is resolved into two components, coincident w...

Remote sensing discoveries of hydroxyl and water on the lunar surface have reshaped our view of the distribution of water and related compounds on airless bodies such as the Moon1–3. The origin of this surface water is unclear4, but it has been suggested that hydroxyl in the lunar regolith can result from the implantation of hydrogen ions by the solar wind1,5. Here we present Fourier transform ...

[1] A correspondence of the lunar regolith-layer thickness to the lunar digital elevation mapping is proposed to tentatively construct the global distribution of lunar regolith-layer thickness. Using Clementine ultraviolet visible multispectral data, the global spatial distribution of FeO + TiO2 content on the lunar regolith layer is calculated. Thus the dielectric permittivity of the global lu...

Drilling samples of lunar soil is an important and indispensable part of China’s lunar exploration project. The drill bit temperature during the drilling process is one of the key concerns for scholars, especially for the hard lunar rock drilling in vacuum. In this article, the simulation analysis of drilling in atmosphere and vacuum is conducted. Moreover, a fiber grating temperature measuring...
