1·We could send a lander to drop a drilling probe through the kilometers-thick ice or attempt to find a huge fissure to access the sub-surface ocean.
我们可以发射一个着陆器，向该星球投放一个有钻头的探测器，钻通其几公里厚的冰面；或者尝试去寻找一个巨大的裂缝进入地下海洋。
2·The cave narrowed after a while, but we were able to continue through a narrow gap by crawling into a water-filled fissure in the rock.
爬了不久，山洞变得越来越窄，爬过一条满是水的岩石裂缝，穿过狭窄的山口，我们得以继续前行。
3·A fault is essential for creating any deposit of gold, as mineral-rich fluids pumping through the fissure for eons gradually concentrate the ore there.
断层对于形成金子有着至关重要的作用。富含矿物质的水流在数亿年间不断冲刷裂缝，逐渐累积成了矿石。
4·But air picks up speed as it approaches a fissure, said Geoffrey Landis, a physicist at NASA's Glenn Research Center in Cleveland.
但空气在接近裂缝的时候速度会越来越快，杰弗里·兰迪斯说，他是美国宇航局在克利夫兰·格伦研究中心的一位物理学家。
5·But the new tower was found to contain a fissure, discovered in 1939, which is very slowly spreading.
但在1939年钟楼就被发现存在裂缝，并以缓慢的速度蔓延开来。
