This is the first laser communication via satellite with Earth

This is the first laser communication via satellite with Earth

Until now, space agencies have supervised missions of space probes or robots Wireless communications. Needless to say, this is not a perfect solution. Therefore, scientists decided to use laser powerTo transfer data between space facilities and objects on Earth faster and more accurately.

This is how the project was created Laser communication relay display (LCRD). According to NASA scientists, the system consists of two ground stations located in California (OGS-1) and Hawaii (OGS-2). These facilities were chosen not by chance. These locations have the best weather conditions for most of the year, than any other location in the United States.

The engineers also made sure that the two stations complemented each other when unfavorable weather conditions occurred over one of them. Objects will follow STPSat-6 . satellitethat will be placed during the experiments Laser Communication Relay System. The tests will last for two years, but the first stage, which was conducted on another satellite, showed that the system is already working and fulfills the hopes placed on it.

Satellites STPSat-6 It will fly into orbit tomorrow (07.12) aboard Atlas V. During the tests, scientists will send a signal with a laser beam from the deck of the ship. International Space Station to the STPSat-6 satellite, and then to the OGS-1 facility in California. NASA plans to use its innovative system to High speed data transmission to the ground From aboard the International Space Station. In the future, a similar system will include other space stations, hotels, and even bases on the Moon or Mars.

Interestingly enough, the Pentagon recently announced that it is testing in orbit Wireless power transmission system. The military revealed that the system can deliver power from orbiting solar farms directly to satellites or aircraft and to the Earth’s surface, even through clouds, and then between any objects.
