Laser deep space communication technology can quickly transmit signals to deep space spacecraft

A few days ago, American astronauts are testing deep space communication technology, using laser technology to quickly transmit signals to deep space spacecraft
.
The successful test of this technology can realize that astronauts can quickly receive high-quality communication signals on Earth, overcome the loneliness of astronauts when sailing, and quickly transmit Earth signals to Mars and other planets
.

Deep space communications, that is, the transmission of information from deep space and other stars acquired by spacecraft back to Earth
.
Scientists believe that the biggest problem with deep space communication is the time delay, in low-Earth orbit, the delay is almost imperceptible, but if you go to Mars, then the astronaut's instructions and information transmission will have a half-hour round trip delay, and the communication between the ground control center and the deep space spacecraft cannot be maintained
.
At this point, if you can't quickly establish contact with the ground, astronauts will be less productive, and their psychological loneliness and frustration will occur
.

The researchers believe that if astronauts live on Mars for a long time, the delay in the signal can lead to disturbances in productivity and psychological aspects
.
Therefore, the use of video communication on spacecraft is very necessary, which requires the use of laser communication technology
.
Laser communication technology is very important for interplanetary missions, whether it is a lunar probe, a Mars rover, a probe or spacecraft in the outer orbit of the solar system, it can establish a high-quality communication channel
with the Earth.
Current spacecraft transmit and receive information through radio waves, and their propagation speed is much less than laser communication, which can provide a larger transmission channel
for massive space information.
