NASA has successfully completed the revolutionary technology testing of laser media in the deep space of optical communication space (DSOC). Nearly a two -year experiment was conducted on the psyche space exploration ship, launched in 2023. 65 communication sessions took place. In the final, the probe transmitted the laser signal to the ground, surpassed the distance of more than 350 million, reported New science.ru.
The DSOC system uses laser radiation to encrypt and transmit information between spatial equipment and land stations. Technology combining optical terminals on the board on the probe with strong ground stations: to set up communication, ground observatory first send laser signals to support the probe. This allows the terminal on the board to aim to exactly its laser beam back to the ground. The signal is made by large telescopes, in which the photons are collected by high -efficient detectors into useful data.
According to the media, some records are located in the test. Therefore, in December 2023, from a distance of 30 million km, a video was transferred to a super high resolution with a little of 267 Mbit/s. And in December 2024 of the past, a range of optical communication was broken: Data applied from a distance of 494 million km. This is more than the average distance between Earth and Mars. In total, in the mission, the ground stations have passed 13.6 Terabits scientific and technical information.
According to experts, the success of DSOC has a strong basis for the mission with drivers and robots in the future so that the fire and many further corners of the universe.
Psychology is an American spacecraft to study the same psychology of metal asteroids, which can clarify the origin of the planet nucleus. The project is controlled by the laboratory of the reaction movement. It is hoped that the probe will come to the asteroid and the trajectory approaching it in 2029.
