课文朗读
The LEGO robot in the European Space Operations Centre in Germany began to receive messages and then drive around last October. But the driver, who was operating the machine remotely, wasn’t in the building. She wasn’t even on the Earth.
去年十月，位于德国境内欧洲航天运行中心的乐高机器人，开始接收讯息并四处行动。但以远程操作这部机器的驾驶员并不在此栋建筑物内－她甚至不在地球上。
About 240 miles above the planet, Sunita Williams was on the International Space Station, using a laptop to control the robot. Williams, a commander on the station, was using a new type of “Internet” that could one day work between different planets. The technology, developed by NASA and the European Space Agency, is called the Disruption Tolerant Network, or DTN. Because signals have to travel deep into outer space, sometimes they are delayed or disappear for a little while. This new type of Internet plans for these drops in signal between users, unlike the regular Internet connections we use on the Earth. Hence, it was given the name “disruption tolerant.”
地球上空约240英哩处的国际太空站中，苏妮塔．威廉丝使用一台笔记本电脑遥控这台机器人。这位太空站指挥官正使用一种未来可能用于不同星球之间的新型「互联网络」。此项由美国国家航空暨太空总署及欧洲航天局共同研发的科技称为「容断网络」。由于讯号必须深入外层空间，有时会有短暂延迟或消失的现象，而这种新型网络主要便是在应付这些用户间可能会有的断线问题，与我们一般在地球上使用的网络联机方式不同，因而有「容断」之称。
With this new network, communication could improve with distant spacecraft and allow for missions farther away from the Earth.
有了这种新型网络，与远距宇宙飞船间的通讯将得以改善，而欲展开距离地球更加遥远的太空任务也不无可能。
