英语听力：自然百科 行星旅行指南：木星 Jupiter—18

 Every time we send aspacecraft to answer questions, we end up asking more.

 

Clearly, a return to Jupiter isn't to stars.

 

(Here we go.)

 

In 2003, with fuel andpower running low, Galileo's 14-year odyssey¹ was brought to an end,deliberately to ensure Europa remained uncontaminated by an out-of-controlspacecraft with a load of earthly bacteria.

 

I was responsible fo rGalileo orbiter and on purpose, my friends always remind(ed) me to say, ‘Hi,make sure you tell people it was on purpose.’ So the idea was to, you know,come into the atmosphere of Jupiter with(in) a ferocity that it would break up and be destroyed, you know, pretty much right away. It's now part of Jupiter.

 

Meanwhile, back on Earth,our return to Jupiter is being planned. In the construction bays of Lockheed Martin, the Juno spacecraft is taking shape,getting ready for its close encounter later in the decade.

 

And looking ahead, NASA andthe European Space Agency are joining forces to send two spacecraft/, one each to orbit Ganymede and Europa. This/essential detailed² reconnaissance / will set the stage for the ultimate goal of exploring an alien ocean by robot submarine.

 

Europa is a good place for robots. Why? Number one,it’s a hackable long way away our propulsion systems that are now ready for/to takeover people there. And second, the radiation /environment on the surface of that moon is dangerous as hell. Five minutes’ exposure to an unshielded our humanand you will see the lethal³ rem dose.雷姆剂量So you don't want to put people on Europa. But we can definitely put robots there. And is there a reason to go? You bet, right? It's a totally unexplored world and it probably has the highest probability of life off thisplanet.
