【语篇导读】随着时代的发展，人类不再满足于探索地球，而是把目光投向了外太空。浩渺的宇宙还有许多未知的领域等待我们去探索，等待我们去认识。但是，如何保护这些人类尚未涉足的地方，是地球人应首先考虑的一个大问题。美国航天局为此制定了两个指令，并为月球及火星的探索做出了一些相关的规定。
Tw new, updated① guidelines② have been issued by NASA t prevent cntaminatin③ f the mn and Mars by humans. It is aimed at④ ensuring that human visits t ther space bdies will nt have a negative impact n these bdies.
[1] The first f these guidelines t be updated is knwn as NASA Interim Directives (NID) 8715．128, which is cncerned with the lunar rbt and human missins, specifically spacecraft intended⑤ t explre the Mn. Different appraches have been utlined cncerning varius parts f the lunar surface.

Anther area is the landing place f the Apll missins. Astrnauts can visit these sites, but the cnditins fr the visits have t be mre cntrlled, such as having a cmplete bilgical inventry.

【1】The first f these guidelines t be updated is knwn as NASA Interim Directives(NID) 8715．128, which is cncerned with the lunar rbt and human missins, specifically spacecraft intended t explre the Mn.
分析：“which is cncerned with the lunar rbt and human missins, specifically spacecraft intended t explre the Mn. ”是一个定语从句，修饰前面的先行词guidelines。在这个定语从句中，“specifically spacecraft intended t explre the Mn”又是一个过去分词短语，修饰前面的名词spacecraft。翻译：第一个将要更新的指导方针是美国宇航局临时指令8715．128，它涉及月球机器人和人类任务，特别是探索月球的航天器。
【2】The plicy sets ut the framewrk fr future new directives s that Mars can be better prtected when humans set their feet n Mars in the future. 分析：“s that Mars can be better prtected when humans set their feet n Mars in the future”引导一个目的状语从句。在这个目的状语从句中，又包含着一个由when引导的时间状语从句。翻译：该政策为未来的新指令制定了框架，以便未来人类踏上火星时能更好地保护火星。
