The laser communication system is another method of communication that occurs through radio communications in the atmosphere. NASA announced that it used this system to broadcast a video from space in which a cat called “Taters” appears, at a distance of 31 million kilometers from Earth, which represents a sign Historical difference.
The first video from deep space via laser
The video clip broadcast by NASA allows sending future human missions beyond Earth’s orbit. The broadcast confirms the necessity of NASA’s commitment to developing optical communications, which is considered an essential element to meet their future needs in data transmission, according to what NASA stated on its official website.
15 seconds was the duration of the test video transmitted by the NASA demonstration, whose hero was the cat “Taters”, and it belonged to an employee at the Jet Propulsion Laboratory, through the use of an advanced tool called an aviation laser “transceiver”, as the video signal lasted for approximately 101 seconds. seconds in order to be able to reach Earth.
Laser communication technology
Last October 13, it was designed NASA agency Laser communications technology, which it launched with the Psyche mission so that it could transmit data from deep space, was at rates 10 to 100 times greater than modern radio frequency systems that are used today in deep space missions.
The drawings illustrate many features from the technology demonstration, such as Psyche’s orbital path, the dome of the Palomar telescope, and technical information about the laser and its data transmission rate. The Tatter’s heart rate, color and breed are also displayed.
Although the transmission was from millions of miles away, it was able to send the video faster than most broadband Internet connections, said Ryan Rogalin, head of receiving electronics for the project at JPL. After receiving the video at Palomar, it was sent to the laboratory. Jet propulsion online.
