A design of in-situ detector of charged lunar dust (DCLD)
, 2021Charged dust widely exists on the surface of the moon, which is considered to be closely related with many natural phenomena. China's Chang’E-5 lunar mission plans to monitor the charged characteristics of electrostatically levitated dust on the lunar ...

Advances in Space Research, 2013
Abstract An analytic model for the motion of a positively charged lunar dust grain in the presence of a shadowed crater at a negative potential in vacuum is presented. It is shown that the dust grain executes oscillatory trajectories, and an expression is derived for the period of oscillation.

Digital Lunar Exploration Sites Unreal Simulation Tool (DUST)
IEEE Aerospace Conference, 2023NASA's future Artemis missions to the Moon seek to explore areas around the Lunar South Pole. Though humans have previously set foot on the lunar surface, the proposed region provides unique and challenging environments that require insight and ...

Search for Porphyrins in Lunar Dust
Science, 1970Evidence for porphyrins was obtained in the Apollo 11 bulk sample of lunar dust by fluorescence spectrometry and analytical demetallation. The indicated porphyrins showed major fluorescence excitation at 390 nanometers. Abundance was about 10 -10 gram of porphyrin per gram of dust.

The Moon was the first extraterrestrial body to attract the attention of space pioneers. It has been about half a century since an active lunar exploration campaign was carried out. At that time, a series of Russian and American automatic landing vehicles and the American manned Apollo Program carried out an unprecedented program of lunar exploration ...

Lunar Dust Fountain Observed Near Twilight Craters
Geophysical Research Letters, 2020Lunar horizon glows observed by the Apollo missions suggested a dense dust exosphere near the lunar terminator. But later missions failed to see such a high‐density dust exosphere.

Ultrathin Amorphous Coatings on Lunar Dust Grains
Science, 1972Ultrathin amorphous coatings have been observed by high-voltage electron microscopy on micrometer-sized dust grains from the Apollo 11, Apollo 12, Apollo 14, and Luna 16 missions. Calibration experiments show that these coatings result from an "ancient" implantation of solar wind ions in the grains.

Dust charge measurements by the Lunar Dust Experiment
2015 IEEE Aerospace Conference, 2015The Lunar Dust Experiment (LDEX) onboard the Lunar Atmosphere and Dust Environment Explorer (LADEE) mission discovered a permanently present dust cloud engulfing the Moon. The size, velocity, and density distributions of the dust particles are consistent with ejecta clouds generated from the continual bombardment of the lunar surface by sporadic ...

Electrostatic charging of lunar dust
AIP Conference Proceedings, 1998Transient dust clouds suspended above the lunar surface were indicated by the horizon glow observed by the Surveyor spacecrafts and the Lunar Ejecta and Meteorite Experiment (Apollo 17), for example. The theoretical models cannot fully explain these observations, but they all suggest that electrostatic charging of the lunar surface due to exposure to ...
