标题： The lunar surface as a recorder of astrophysical processes

摘要： 月球表面已暴露在太空环境中数十亿年，在此期间积累了各种天体物理现象的记录。 这些包括太阳风粒子以及太阳粒子事件产生的宇宙成因产物，它们保存了太阳过去演化的记录，以及由高能银河宇宙射线产生的宇宙成因核素，这些可能记录了太阳系在时间上的银河环境。 月球表面也可能吸收了来自本地星际介质的物质，包括超新星喷出物和太阳系在过去遇到的星际云中的物质。 由于月球相对较低的地质活动水平、缺乏大气层，以及在其历史的大部分时间里缺乏磁场，月球表面非常适合收集这些天文记录。 此外，月球表现出能够掩埋并因此保存和“时间标记”这些记录的地质过程，尽管要获取这些记录可能需要月球表面具备显著的科学基础设施。 显示英文摘要

摘要： The lunar surface has been exposed to the space environment for billions of years and during this time has accumulated records of a wide range of astrophysical phenomena. These include solar wind particles and the cosmogenic products of solar particle events which preserve a record of the past evolution of the Sun, and cosmogenic nuclides produced by high-energy galactic cosmic rays which potentially record the galactic environment of the Solar System through time. The lunar surface may also have accreted material from the local interstellar medium, including supernova ejecta and material from interstellar clouds encountered by the Solar System in the past. Owing to the Moon's relatively low level of geological activity, absence of an atmosphere, and, for much of its history, lack of a magnetic field, the lunar surface is ideally suited to collect these astronomical records. Moreover, the Moon exhibits geological processes able to bury and thus both preserve and 'time-stamp' these records, although gaining access to them is likely to require a significant scientific infrastructure on the lunar surface.
