The Moon Has Faster Transfer Speeds Than Any Country On Earth


This is Akamai’s recent survey of world internet speeds. Life on the internet is great, in South Korea. Less great in India. But none of these countries have anything on the moon:

NASA’s Lunar Laser Communication Demonstration (LLCD) has made history using a pulsed laser beam to transmit data over the 239,000 miles between the moon and Earth at a record-breaking download rate of 622 megabits per second (Mbps).

LLCD is NASA’s first system for two-way communication using a laser instead of radio waves. It also has demonstrated an error-free data upload rate of 20 Mbps transmitted from the primary ground station in New Mexico to the spacecraft currently orbiting the moon.  

If this connection were used to send, say, a Blu-ray rip of The Dark Knight from the moon, it would take about 30 seconds. Downloading a typical five minute MP3 would take less than a second. Downloading OS X Mavericks, which is about 5 GB, would take a minute. You could send the entirety of Spotify’s music collection — over 20m songs — from the moon, where it is used for moon dancing, the greatest reduced-gravity pastime, in about eight days. There’s no texting on the moon! Only iMessage over Wi-Fi.
