论文摘要
农历挥发物的起源,分布,深度和数量仍然是空旷的问题。月亮挥发物的可能来源之一是在月球火山活动的峰值〜3.5 ga期间,它们的火山量超过了。这种相同的超出气体也会产生脆弱的瞬态气氛,这将促进从火山源到极性冷陷阱的挥发物的传递。尽管这种气氛在月球的演变中可能发挥了重要作用,但由于所涉及的机制的高不确定性水平,人们对此一无所知。古代农历气氛的唯一可靠代理是它沉积的原始挥发物,预计将保存在极性冷陷阱中,并且可以通过样品回报进行研究。因此,在这份白皮书中,我们提倡从月球的极地冷陷阱中返回的挥发性样本应该是Artemis计划的基本组成部分。
The origin, distribution, depth and volume of lunar volatiles remain open questions. One of the possible sources of Moon's volatiles is their volcanic outgassing during the peak of lunar volcanic activity ~3.5 Ga. This same outgassing would also produce a tenuous transient atmosphere which would promote the delivery of volatiles from the volcanic sources to the polar cold traps. Though such an atmosphere could have played an important role in the evolution of the Moon, little is known about it due to high uncertainty level in the mechanisms involved. The only reliable proxy for the ancient lunar atmosphere are the primordial volatiles deposited by it, which are expected to be preserved in the polar cold traps, and could be studied through sample return. In this white paper we therefore advocate that a volatile sample return from the Moon's polar cold traps should be a fundamental part of the Artemis program.
