In order to bring broadband to the moon, scientists used four separate telescopes based in New Mexico to send an uplink signal to a receiver mounted on a satellite orbiting the moon. Each telescope is about 6 inches in diameter and is fed by a laser transmitter that beams information in coded pulses of infrared light.
Since our atmosphere bends the signal as it travels to the moon, the four telescopes transmit the light through different columns of air, each with different bending effects. This setup increases the chance that at least one of the laser beams will interact with the receiver, and establish a connection with the moon.
And if you’re fixing to binge on Netflix on the moon, the connection isn’t too bad, either. Scientists managed to send data from Earth to the moon at a rate of 19.44 megabits per second — on par with slower broadband speeds — and could download information from the moon at a rate of whopping 622 megabits per second. According to Wired UK, that’s over 4,000 times faster than current radio transmission speeds.
