Characterizing the Lunar Particulate Atmosphere with the Autonomous Lunar Dust Observer (aldo)

چکیده
Introduction: Billions of years of meteoroid bombardment have shaped the lunar surface, created and stirred the lunar regolith, and covered the moon with dust. Since the Apollo era, the particulate atmosphere and mobility of dust, have been recognized as both a hazard to human health and a challenge to equipment function and longevity. The NASA Constellation Program promises sustained human and robotic presence on the moon, affording a unique opportunity in the next decades for better study of the natural dust formation, lofting and redistribution processes on airless bodies such as the moon, as well as the development a working understanding of the effects of human activities on the lunar dust environment.

Autonomous Lunar Dust Observer for the Systematic Study of Natural and Anthropogenic Dust Phenomena on Airless Bodies
Introduction: Most of the lunar surface is covered with a thick layer of regolith composed of rock fragments and dust that have evolved through billions of years of constant destructive meteoroid bombardment. From the Apollo mission experiences, it is clear that long term lunar surface experiments and human activities, as anticipated for the Constellation program, must necessarily deal with the...
متن کاملA new model of continuous dust production from the lunar surface
We estimate the production rate of lunar ejecta escaping from the Moon, taking into account the probable surface condition, i.e. the regolith layer. The production of lunar ejecta from a particulate surface is more effective than that from a hard surface. In our model for a particulate surface, the production rate is estimated to be about 10−3kg s−1, about 20 times higher than that calculated b...
متن کاملShape and Size Relationship of Several Lunar Dusts: Preliminary Results
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 [...
متن کاملElectrical Phenomena on the Moon and Mars
The Moon and Mars represent intriguing and divergent case studies where natural electrical processes may occur in environments beyond our more familiar terrestrial experience. The windy, Aeolian environment of Mars likely produces substantial electrical activity via the tribo-electrification of individual dust grains that occurs during atmospheric disturbances. While there may be some analogies...
متن کاملThe Lunar Environment: Determining the Health Effects of Exposure to Moon Dusts
The Earth’s moon presents a hostile environment in which to live and work. There is no atmosphere to protect its surface from the ravages of cosmic radiation, solar wind and micrometeorite impacts. As a result, the moon’s surface is covered with a thin layer of fine, charged, reactive dust capable of entering habitats and vehicle compartments, where it can cause crewmember health problems. Duri...
