Two Greek telescopes will “talk” via a laser beam to a NASA spacecraft

Telescope On the head of Helmus in Achaia and this on the Cryoneri in Corinth It has been selected by the European Space Agency (ESA) to participate in a pioneering communications experiment with a spacecraft located hundreds of millions of kilometers from Earth.

The mission began on October 13, 2023 with a goal Asteroid 16 Psyche It is located between Mars and Jupiter. The asteroid is considered a remnant of the era in which the solar system was forming 4.5 billion years ago.

Scientists are testing the use of optical lasers to communicate with spacecraft, instead of the radio waves currently used.

Spyros Vassilakos, deputy head of the National Observatory in Athens, told ERT that the experiment on the two Greek telescopes will take place in the summer of 2025 after the installation of special equipment. The researchers will send a laser beam from Cryoneri to the spacecraft, which will then be millions of kilometers away. The response will be sent by sending a message that Helmus should receive.

Mr. Vassilakos added that Greek researchers are pioneers in conducting similar experiments. He added: “Two years ago, we made an optical connection with the largest communications satellite at a distance of 37,000 kilometers. This opened the way for us to establish a connection over very long distances.”

Wideband optical laser technology is the technology of the future because it will be able to carry Huge amount of dataAt high speeds with minimal risk of eavesdropping.
