很多朋友都看过,由皮克斯制作,迪斯尼08年负责发行的动画长片《WALL·E》。人类已经离开环境恶化的地球,只留下瓦力在成山的垃圾中寻找人类文明的过往繁华。影片的前段,相信透过色彩光线构图都无比精致的画面,牢牢掌控观众情绪的是一种忧郁浓重的孤独感。


无独有偶,在一个并不存在的T字头网站上,@MESSENGER2011 断断续续地写道:





下面这篇阅读会帮你了解这个故事的来龙去脉。

Mercury Mission Set to End with Dramatic Crash


By Alexandra Witze and Nature magazine


1. On April 30, after more than four years in orbit around Mercury, NASA's MESSENGER probe will plunge to its doom. Out of fuel and long past its intended one-year mission, the spacecraft will crash into the planet's surface at a speed of 3.9 kilometres a second.

2. Mission head Sean Solomon, a planetary scientist and director of the Lamont-Doherty Earth Observatory in Palisades, New York, sat down with Nature to talk about what MESSENGER has accomplished since it launched in 2004. The following interview has been edited and condensed.

A
3. Mercury was the last frontier of our knowledge about the inner Solar System. We had multiple missions to Mars and the Moon, and only Mariner 10 had gone to Mercury. It flew by three times [twice in 1974 and once in 1975], and its images gave us our first ideas about Mercury’s geological history. But there was so much unanswered. It was a planet that was really missing a lot of key information.

B
4. Probably the most disappointing aspect of Mercury turned out to be how nearly uniform its colour was. The effects of space-weathering must be so strong, and so rapidly acquired, that there were no convincing mineralogical signatures.

5. The hollows were a landform we didn't expect. They are bright depressions created by the loss of near-surface material. They are some of the youngest features on the planet, and speak to some sort of unstable material whose identity we are still working out.

C
6. We confirmed that there are areas of the polar deposits where water ice is stable for geologically long periods of time. The planet closest to the Sun harbours water ice at both poles.

7. There is dark material covering the polar deposits, which we have identified tentatively as organic-rich material of the sort that we see in the outer Solar System, in organic-rich meteorites and comets. I don’t think anybody could count Mercury as habitable. But it is a witness to the delivery of the ingredients for habitability, from the outer Solar System to the inner Solar System.

D
8. The magnetic field of Mercury is dipolar, but the dipole is not located at the center of the planet like it is for Earth and most other planets. It's substantially offset, by about 20% of the planetary radius. There were no models that predicted that. I've managed to disturb some of my colleagues by asking them to think about whether Earth went through a history of its magnetic field that was characterized by a geometry like Mercury's.

E
9. The big surprise was the high abundances of volatile elements. All of the ideas for how Mercury got put together predicted that it would be depleted in volatiles, much like the Moon. But instead, we see sulphur [at] ten times the average for Earth. We see sodium and potassium. We see chlorine, one of the most volatile elements that we have the ability to measure.

10. That means we really didn't understand the particular way that Mercury became an iron-rich planet. It wasn't a process with sustained high temperatures that drove off the volatile elements. I don't think the final chapter has been written on what the most likely explanation is for the formation of Mercury.

F
11. They have a dual spacecraft with many more instruments than us. They will have a more-even view of the two hemispheres. The different viewing geometry, the slightly different mix of instruments and the fact that they have two spacecraft will give them opportunities.

G
12. The last couple of hours will probably be pretty quiet. There will be a final orbit when the spacecraft passes behind the planet and we won't hear from it again. We think that we know where the impact will be, near the crater Shakespeare. [When it hits], it will become one of the youngest, albeit one of the tiniest, impact features on Mercury. And that will be the end of MESSENGER.

13. I have worked on the mission for 19 years. It's like losing a member of the family. Even pre-knowledge doesn't prepare you completely for the loss.


a

What does it(Mercury) look like close up?


b

What did you find at its poles?


c

In 2017, the European and Japanese space agencies plan to launch the BepiColombo mission to Mercury. What's left for it to discover?


d

Why did you want to send a mission to Mercury?


e

What will MESSENGER’s impact day be like?


f

Which MESSENGER findings surprised you?


g

What about its weird magnetic field?


(答案见文章底部)




【一些无关痛痒的提示】


plunge to its doom(P1)

plunge 做不及物动词时,有向前向下跌落,俯冲的意思;

to one's doom 是死亡的文饰的说法,send a man to his doom使某人陷入绝境。


space-weather(P4)

字面看是宇宙的气候现象,不同于大气层内的各种天侯,此处(我认为)是指太阳风,耀斑,黑子等现象。


speak to something(P5)

(书面语)讲述某事,此处可以意译为:这些晚近出现在水星上的地貌特征,是由一些我们仍在研究(它到底是什么)的不稳定物质(的流失)造成的。


dipolar(P8)

偶极子的,指水星有正负两个磁极。


volatile elements(P9)

化学性质活泼的元素,本段中出现的sulphur(sulfer)硫,sodium钠,potassium钾,chlorine氯,都是化学性质活泼的元素。





【长亭外,古道边】




就这样,2004年8月发射,2011年3月进入水星轨道,样子丑萌的信使号MESSENGER探测器,超期服役3年多以后(原设计预期是执行任务一年),终于在2015年4月30号,扑入了水星大姐姐的欧派。


默默飞行了87.3亿英里;

绕着离太阳最近的鸟不拉屎的行星转了4100圈;

度过8个水星日(一个水星日相当于大约176个地球日,因为水星的自转很慢),1504个地球日;

回传了289,265幅图片……


最后一天,它用告别的口吻写道:


于是,在这个不存在的T字头网站上,人们纷纷向信使告别:


@Sxxxh Hxxxt - That'll do friend.That'll do.

(你已经做得足够多了朋友,这就够了)


@Txxxxxxxxxr - You done good!


@Stxxx Hxxxk - until we meet again


@Bxxxxt Sxxxs - Farewell little buddy


@cxxxxxo - sleep well, sweet princess. You'll be remembered.


@dxxxxl42 - I hope that big wide round thing will be friendly to you!

(大姐姐的欧派会很美好!)


@SxxxxxxxxxC - You have been a good stellite and a great explorer - thank you.


@Gxxx Mxxxs - We're gonna miss you!


@Hxxxxx Sxxxxxxx - *tear*


@Axx Sxxxxxs - Godspeed.

(一路平安,好运等的祝语)


@Bxxxxxsxxxy - good job, farewell, may the wind be ever at your back.

(一路顺风)


@MBOxxxxxxxxxy - on successful lithobreaking! :-/

(着陆顺利哟!好吧大哥你真是个乐观地人儿)


@Lxxxxl - So cool.

(啧啧)


@Jxxxxxxx Dxxxe - Let Mercury know it's been kissed.

(亲丫呢不用给我留面子!)


@Pxxxx_Lyxx - This is very alarming tweet. Does anyone out there know @MESSENGER2011 who can contact the local authorities?

(“不好啦!谁认识这人呀快点报警啊要出人命啦!”我个人很喜欢这条,很好的告别是不么)


@lxxxxxxxxxxl - Stay gold, ponyboy, stay gold.

(gold指年轻有活力,有希望等状态,这姑娘有点文青气质,这句话也蛮适合写在笔记本扉页上,男生就算了除非是我弟wenxuan)


恩,还有一条很值得我们聊聊,上图——


没错,这位自称是罗塞塔计划的小菲莱(不是小韭菜),她的自我介绍是:

Rosetta dispatched me onto Comet #67Pon Nov 12th. Unofficial account.Sleeping on Comet #67P/C–G

基本可以判断是一位有爱的菲莱粉。


说说这条回复 We'll always have Paris.

语出经典影片《卡萨布兰卡》,没看过的同学听我超有品(模糊)剧透:战争年代,男A碰到女A和男B二人正计划逃离。男A发现女A是失散多年的情人与之相认并重燃情火,但最终选择放弃自己的幸福成全女A和男B逃走自己断后。

这句话就是男A临别时对女A说的,大意是:我们都记得美好的日子(指在巴黎)(你快走吧我没事)。

这个典故用在此处可以理解为:我们爱你信使号,但是你该走了,放心地去吧。

怀旧感伤甜蜜,不舍又让人释怀,真是相当高级的用典。
