NASA transmits data to the moon at a new record speed

NASA has set a new data transfer speed record. Data has never been transmitted so quickly to both the moon and a spaceship.

NASA transferred data from the earth to the moon at a speed of 622 megabits per second (Mbps). According to the space agency, a new record was set on the 385,000-kilometer route. The Lunar Laser Communication Demonstration (LLCD) was used, a two-way communication system developed by NASA, in which the data can be sent back and forth between two transmitters using laser beams instead of radio waves. Data from a base station in New Mexico to a spacecraft in orbit at a speed of 20 Mbps has also been sent error-free via LLCD.

LLCD is hailed by NASA as the first major step in building the next generation space communication system. The switch to pulsed lasers instead of radio waves for the transmission of communication has become necessary because the need to send ever larger amounts of data is also growing. At some point in the future it will also be possible to receive high-resolution images and 3D videos from space via LLCD.
