Laser signal came to Earth nasa from 22 crore km who sent it know

American space agency NASA launched Psyche spacecraft in October last year. It has set out to learn about an asteroid named Psyche. Spacecraft lands on Earth after reaching deep space send signal Used to be. Recently it has sent a signal to scientists from a distance of 22.53 crore kilometers from the Earth. Deep Space Optical Communications (DSOC) system is installed in this spacecraft. Its purpose is to make laser communication possible over long distances in space. This system is said to be much faster than the existing systems.

The DSOC system has proved its capability by sending signals to Earth from a distance of 22.53 crore kilometers. According to NDTV report, the laser communication demo successfully sent engineering data from a distance of 140 million miles (about 225.3 million kilometers) after interfacing with the radio frequency transmitter of the Psyche spacecraft. This distance is 1.5 times the distance between the Earth and the Sun.

What is the meaning of laser beam signal?

Generally, when spacecraft in deep space send signals to Earth, their bandwidth is limited. Laser beam signals could be useful for future missions. NASA says that this system can deliver messages at a speed 10 to 100 times faster than existing space communication systems.

Why is Psyche Asteroid special?

Regarding the Psyche asteroid, it is estimated that it may contain iron, nickel and gold worth 10,000 quadrillion dollars. There are 15 zeros in a quadrillion. This is the number coming after trillion. With this you can estimate the price of Psyche. To know about this asteroid, NASA has launched Mission Psyche. However, NASA will not extract anything valuable from this asteroid.
