Without the thruster, the washing-machine-size Philae would have to rely on ice screws on its landing legs and the harpoons to anchor it to the comet.

The landing culminated a tense day as Rosetta maneuvered to the correct position to let Philae go-moments of celebration were interspersed with long, quiet stretches of waiting.

在这紧张的一天中，“罗塞塔”移动到正确的位置，让“菲莱”脱离了它，而着陆彗星表面是这一天的高潮——人们庆祝了这些时刻，其间则穿插着漫长、静默的等待。

Scientists at ESA mission headquarters erupted in applause shortly after 4pm GMT as a radio signal from Philae 511m km away confirmed that the washing-machine-sized probe had reached the surface.

在格林威治时间周三下午4点后不久，欧洲航天局任务总部的科学家们爆发出热烈掌声，“飞来号”从距离地球5.11亿公里的地方发来的一个无线信号证实，这个洗衣机大小的探测器已在彗星表面着陆。

The biggest challenge, says Stephan Ulamec, manager of the Philae lander programme, was how to design a probe to land on a body whose makeup they had little knowledge about.

据菲莱项目的负责人斯蒂芬介绍，在这20年里遇到的最大挑战是对彗星构造了解较少，不知道该如何设计这个探测器。

Dr. Ulamec said fluctuations in the radio link and the generation of power by the solar panels suggested that Philae may have bounced off the surface before settling down again.

尤拉米克博士说，从波动的无线电联系以及太阳能电池板的发电状况来看，“菲莱”可能从彗星表面反弹出去，然后再次着陆。

The orbiter is to re-establish the radio link in the next day, and mission managers hope then to better understand the stability of Philae's footing.

轨道飞行器将在第二天重新建立无线电联系，该任务的负责人希望届时可以更好地了解“菲莱”基脚的稳定性。

Before the landing, mission managers said anchoring would be needed because 67P's gravitational pull is too weak to hold Philae firmly in place.

在着陆前，此次飞行任务的主管们表示，着陆器需要固定，因为彗星67P的引力太小，无法让“飞来号”紧紧固定。

What is clear is that Philae touched down very close to the targeted zone on the head of the rubber-duck-shaped comet.

但可以确定的是菲莱着陆的位置离预订区域非常近，位于这颗鸭子形状的彗星的头部。
