: 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

: 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
其實露明尼早就說過了
問題不在技術
而是在人發展月球軌道後
人類與未來勢必製造的機器人能不能互相信任才是最大問題
還湯馬斯博士說的忘惹
