 Wi-Fi on the moon is now as fast as the Wi-Fi in your living room
現在月球上的wifi已經跟你家的一樣快了
Researchers at NASA and MIT have figured out how to beam wireless
connectivity from a ground base in New Mexico
Timothy McGrath, GlobalPost

Life on the moon just got a whole lot more awesome. Sure, you’ve got to wear
a spacesuit and there’s not much to do in the way of recreation and
nightlife.
在月球上的生活變得更有意思了。當然你得要穿太空衣，而且沒什麼娛樂和夜生活

But that’s all okay now, because there’s Wi-Fi.
但是現在一切都沒問題了，因為那裡有wifi

Researchers at NASA and MIT have figured out how to beam wireless
connectivity from a ground base in New Mexico to the moon using
telescopes and lasers.
研究員找出利用雷射和望遠鏡做無線傳輸的方法

It’s as cool as it sounds.

Here’s how it works. The transmission utilizes four separate telescopes
connected to a laser transmitter that feeds coded pulses of infrared light
through it. Those signals travel toward a satellite orbiting the moon.
Researchers have managed to make a connection and transfer data at a speed
approximating slower Wi-Fi speeds on Earth.
它的運作方式是：利用四台望遠鏡把紅外線雷射打到繞月衛星上面。
現在的連線速度已經跟地球上的慢速wifi（比如說台灣）差不多了

It’s no easy feat, and it doesn’t work every time.


“Communicating at high data rates from Earth to the moon with laser beams
is challenging because of the 400,000-kilometre distance spreading out the
light beam,” said Mark Stevens of MIT Lincoln Laboratory. “It’s doubly
difficult going through the atmosphere, because turbulence can bend
light-causing rapid fading or dropouts of the signal at the receiver.”
考慮到40萬公里的距離和大氣擾動，月球和地球間的高速傳輸並不容易。


Using four telescopes increases the chance that one of them will successfully
hit the satellite.
利用望遠鏡可以增加光打到衛星的機會。

The scientists-turned-Wi-Fi-troubleshooters will present their research
at the CLEO laser technology conference on June 6.

Such good news for life on the moon. We can now power-watch “West Wing.”
現在可以在月球上看影片了

4.備註:
覺得台灣網路慢的人不考慮去月球上打卡上ptt嗎？
討厭4G限速或是iPhone頻寬不支援的也可以上月球wifi吃到飽
