Infrared laser signals are a technology that NASA will develop to improve communication between space and Earth.
there NASA is preparing to open new horizons, is the boundary of communications between space and Earth, using infrared laser signals and no longer radio waves. The project is ambitious and follows in the footsteps of China’s five-year program. The first steps have already been taken, as evidenced by a recent press release in which NASA announced that it has begun construction of the second ground station, which will send or receive messages using lasers. Headquartered in Hawaii, the first station was built in California.
Limits are not to be underestimated
One of the limitations of this innovative system is disruptions that can cause atmospheric disruptions in communication, such as disabling or even blocking messaging. It is no coincidence that the locations of the two ground stations were chosen, especially in Hawaii, where the sky is supposed to be clear for most of the year. In this first phase of testing, meteorological conditions will also be monitored to select the best location and therefore the station from which to transmit.
Increase data transfer speed
On the other hand, the advantages of laser contact are much greater. First of all, the transmission speed, and thus the amount of data transferred. High-resolution images will be obtained in less time from space telescopes. But the volume and consumption of the entire part affecting communications will also be reduced. In fact, the components of optical systems are more compact than those found in radio waves and in enclosed environments, such as those in spacecraft and sensors, and the benefits are immediate and visible.

cubes
Cubesat has been launched into orbit by Low Earth to test this new technology and discover its possible limits and possible areas of application. Cubes are relatively inexpensive systems that are used only in this type of experiment. The goal is to test laser communication first on a planetary level and then move to a more ambitious interplanetary level aimed at the Moon and Mars, in the hope that a transmission speed of up to 200 Gbps can be reached.
