SpaceX星鍵計畫 Starlink
Satellite-based, high-speed internet service
透過低軌道衛星群提供覆蓋全球之高速網際網路
你是否曾凝望著夜空，尋找星宿和流星？
或許你曾注意到有個小而亮的東西飛掠過天際。
如果那個亮點沒有尾巴的話，那麼你極有可能看到了一顆低軌道衛星。
要一直到2019年的年中，才開始有可能單憑肉眼就看到衛星。
2019年5月23日那天，伊隆‧馬斯克的Space×太空探索技術公司旗下分部—星鏈，發射了六十顆網路衛星。
在意欲打造全球寬頻高速衛星網路的雄心計畫中，星鏈只是首部曲。
藉由將衛星保持於近地軌道上，星鏈便得以提供堪比有線或光纖網路的存取服務。
衛星網路服務並非新的科技發展。
自從1990年代開始，通訊衛星就已經替偏遠地區的民眾提供網路服務。
星鏈甚至還不是首家企圖打造低軌衛星系統網路的公司；Teledesic這家由微軟出資的公司就曾經嘗試做同一件事，只不過該公司已於2000年代初期宣告破產。
然而，星鏈正穩穩地走在成功的大道上。
到了2021年年中，天空早就已布滿足足一千多顆運作中的星鏈衛星。
Have you ever gazed into the night sky, looking for constellations and shooting stars? Perhaps you've noticed something small and bright streaking across the sky. If it has no tail, you are most likely seeing a satellite in low earth orbit (LEO). It was not until mid-2019 that seeing satellites with the naked eye started to become likely. On May 23, 2019, Starlink, a division of Elon Musk's SpaceX company, launched 60 internet satellites. This was just the first part of an ambitious plan to bring satellite internet with broadband speeds to people across the globe.
constellation星座；星群
The eighty-eight constellations we still recognize today were picked in 1922.
a constellation of群集
The conference was attended by a constellation of well-known doctors and other health professionals一群知名的醫師和醫療專家.
The residents of the apartment building made a constellation of requests from fixing the leaking roof to a more secure entrance.
streak疾駛；飛奔
We watched a cat streak across our lawn as it tried to catch a mouse.
streak留下條紋
Maryann's hair was streaked with red and orange.
streak條紋；線條
After playing by the stream, the little boys had streaks of dirt on their faces.
stellar （adj.）星的；星形的；恆星的
gaze/ stargazing vi.凝視，注視，
stargazing（n.）星辰凝望，天體觀察；天文學；占星學
the naked eye
shoot for the stars追求遠大目標；立大志；志氣比天高
You have to go and shoot for the stars.
By keeping the satellites in a low orbit, Starlink can offer a service that is comparable to a cable or fiber-optic network.
Satellite internet service isn't a new development. Communications satellites have provided internet services to people in remote areas since the 1990s. Starlink isn't even the first company to attempt to create a network of low-orbit satellites. Teledesic, which was funded by Microsoft, tried to do the same thing but went bankrupt in the early 2000s.
Starlink is well on its way to success, however. By mid-2021, there were well over a thousand operational Starlink satellites in the sky.
comparable比得上的；類似的
Sarah's washing machine is comparable in cost to her brother's.價格不相上下
Jimmy and Billy are twins, but they are not comparable in height or weight.
comparability 相似性
Even though Billy and Jimmy are twins, there is little comparability between them.
optional運行中的；工作中的
The workers said that they would have Bryan's boat operational by late afternoon.恢復運作
Even though airlines didn't fly much during the past year they are almost fully operational now.正常營運
With all of the changes of the law, the operational plans of many police forces are being adjusted.執行計畫
To ho bankrupt
Well on one’s way
You’ve already got a pretty good start, you already have, you’ve taken…you’ve already begun your journey to success.
broadband寬頻在基本電子和電子通訊上，是描述電子線路能夠同時處理較寬的頻率範圍。寬頻是一種相對的描述方式，頻帶的範圍愈大，也就是頻寬愈高時，能夠傳送的資料也相對增加。譬如說在無線電通訊上，頻率範圍比較窄的頻寬只能傳送摩爾斯電碼，傳送高品質的音樂就需要較大的頻寬。電視天線的寬頻代表能夠接收數量較多的頻道。
fiber-optic光導纖維，或稱光學纖維，簡稱光纖，是一種由玻璃或塑料製成的纖維，利用光在這些纖維中以全內反射原理傳輸的光傳導工具。微細的光纖封裝在塑料護套中，使得它能夠彎曲而不至於斷裂。通常光纖的一端的發射裝置使用發光二極體或一束雷射將光脈衝傳送至光纖中，光纖的另一端的接收裝置使用光敏元件檢測脈衝。包含光纖的線纜稱為光纜。
It's been raining all week.
I sure hope it won't rain on Saturday.
Are you planning something outdoors?
It's Moon Festival.
After dinner, my family usually goes to the rooftop to eat pomelos and mooncakes while gazing at the moon.
Ah... Moon Festival traditions.
Ah... Moon Festival traditions.
My family hasn't done that ever since we moved to the
city years ago.
We've done it every year since I can remember.
Gazing at a full moon with family is a wonderful
experience.
The moon looks especially big and bright this time of year.
Hmm ... Let's check the weather for Saturday.
Hey! Looks like it will be clear skies Saturday.
Maybe I'll head up to rooftop, too!
Hey Bill, do you want to split this box of mooncakes with me?
What flavors are there?
Mung bean, red bean and lotus seed.綠豆、紅豆、蓮子
What is the mooncake dough made of?
The dough is made from flour, syrup and cooking oil.
I'd like to try the one with a lotus seed filling.
It's really good.
Yes, it is.
Don't eat too many, though.
Mooncakes are really high in calories.
Here, take some pomelos home with you.柚子
My boss gave me a big box and I can't finish it all by
myself.
OK, thanks.
What are pomelos like?
They're like big, mild-tasting grapefruits. 葡萄柚
