STARLINK Satellite-based, high-speed internet service
Space X 星鏈計畫/透過低軌道衛星群 提供覆蓋全球之高速網際網路

關鍵詞  operational, astronomer 天文學家, collision, catastrophic, tweak, geosynchronous, debris


If all goes according to plan, Starlink will have enough satellites to offer global internet services by the end of 2021.
◎如果一切照著計畫進行,到了二o二一年年底,星鏈將會擁有足以提供全球網際網路服務的衛星群。
>> Yesterday we began learning about the satellite company Starlink and Elon Musk's ambitious plan to bring satellite internet with broadband speeds to people across the globe.昨天,我們開始了解衛星公司 Starlink 和埃隆·馬斯克(Elon Musk)雄心勃勃的計劃,即為全球人民提供寬帶速度的衛星互聯網。
>> But as with most of our technology articles, there are downsides or challenges. 但與我們的大多數技術文章一樣,也存在不足或挑戰。
● downside (n) 缺點
>> If all goes according to plan This means that you have a plan, and if everything goes according to plan, that means nothing went wrong, you had... success carrying out your plan.
>> Maybe you're going to an airport or on a road trip, and you might say, "If all goes according to plan, we should reach our destination by 6 o'clock p.m."
Because you have a schedule, you want to try to stick to your schedule.

Not everyone is happy with the idea, though.
但是, 並非每個人都對這計畫感到開心;

>> Hopefully, uh, we'll have global internet services, assuming with high speeds, by the end of this year. We read here.
>> Not everyone is happy with that idea, though.
>> I would..., maybe even use the word "thrilled"
>> Have you ever heard that?
>> Like: I'm not too thrilled with that idea.
thrill  (v)激動

Astronomers in particular are very concerned.
◎尤其是天文學家紛紛表示憂心。
astronomer (n) 天文學家
· Bill is an amateur astronomer, and he spends a lot of time with his telescope.
amateur    (a)業餘的

in particular  (a)尤其的

>> Now we use the phrase " in particular " to talk about something that is very specific. It kind of means "'especially."
>> It's used to show that something applies to someone or a group of people perhaps more than it applies to other people.
>> You could say teachers in particular are very concerned about the new testing strategies.
>> Well, what are you concerned about in particular, friends?
>> Maybe you're concerned about it more than your brother or sister or friend is concerned about it.


Unlike satellites in geosynchronous orbits, LEO satellites interfere with telescope observations and leave bright marks痕 on long-exposure pictures.
◎低軌衛星不同於與地球處於同步軌道上的衛星,它們會干擾望遠鏡觀測而且會在長時間曝光的照片上留下亮痕·
● geosynchronous    (n) 地球同步軌道,地球同步軌道上的衛星
● interfere            (v)干擾

● telescope          (n) 望遠鏡
● observation         (n) 觀測
● long-exposure  (n)長期接觸
● exposure           (n)暴露

National space agencies are also concerned.
◎國家太空局也很擔憂;


There have already been near misses involving Starlink satellites.
◎因為已有為數不少差點相撞的事件都牽涉到星鏈的衛星

>> Usage Tip
There have aready been near misses involving Starlink satellites. 
本句以There開頭搭配現在完成式:There示經有過·一事.名詞
「幾乎相撞」的事件,其後的involving為形詞子句化成現在分詞形客修前面的名詞m
misses 為複數型,故動詞要用have+been

 


In space, collisions must be avoided at all costs.
◎撞擊事件在太空中是不計任何代價都必須避免的意外。
collisions   (n) 碰撞·撞
· Even a small collision with another car can cause damage that is expensive to fix.


Objects in orbit move at extreme speeds, and even things as small as a screw can cause catastrophic damage upon impact.
◎太空軌道上的物體均極高速度進行移動,撞擊當下,即使小如螺絲釘的物件也可能導致災難性的毀損。
catastrophic  (a)  災難性的
· Scientists have found clues that certain catastrophic events in the past nearly killed everything on our planet.


◎Eventually, Starlink plans to have 42,000 satellites in orbit.
◎星鏈計畫最終打算要發射四萬兩千顆衛星在軌道上。

◎If even a small percentage of those were damaged, that could fill the sky with dangerous debris.
◎即便這些衛星中只有很小比例的毀損,也可能導致天空布滿危險的殘骸碎片。
debris  (n)殘骸 s不發音


◎Starlink is responding by tweaking the design so that their satellites reflect less light.
◎星鏈則回應表示,透過微幅修改設計,將能使星鏈衛星減少些許反射光線。
tweak   (v) 稍微改進 / (n) 微調改進
· We can tweak this image a bit so that it will quickly load even with slow connection speeds.

◎They also are lowering the orbit distance to about 550 kilometers.
◎他們也將調降軌道高度到大約五百五十公里;

◎That would cause any failed satellites to fall into Earth's atmosphere quickly and burn up.
◎這樣將能讓失效的衛星迅速落入地球大氣層並立即焚毀

◎Starlink still has a long way to go to safely provide the globe with a high-quality internet service.
◎星鏈想安全提供全球高品質的網際網路服務,還有很長一段路要走。

◎But if they can, it will be a major step forward in connecting everyone on the planet.
◎不過,倘若他們能成功辦到,勢必將在連結起全世界所有人這件事上,往前跨出一大步。
