Voyager 1 and 2 spacecraft had embarked on an irreversible journey on humanity’s journey to explore outer space. On its journey that began in 1977, Voyager continues to send signals to our planet. These signals have now been discovered by a radio telescope.

since 2007 Allen Telescope Array (ATA – Allen Telescope Array) It collects astronomical data and searches for signs to find traces of extraterrestrial life in space. Earlier this year, ATA discovered a 15-minute data stream from the Voyager I vehicle.

Message from 23 billion kilometers far

There is no explanation about the data in the signal. NASAs Deep Space Network (DSN) The vehicle using the system transmits 160 bits of data per second. The vehicle, which is currently 23.3 billion kilometers from Earth, is currently heliosphere He takes measurements outside (the sphere made up of particles emitted from the sun that reaches Pluto).

The radio telescope, which has managed to capture the data, is formed by the array of satellite antennas with a radius of 6 meters. co-founder of Microsoft Paul Allen and co-founder of Qualcomm Franklin AntonioATA was founded with the support of ATA and was developed in collaboration with the SETI Institute and the UC Berkeley Radio Astronomy Laboratory (RAL).

full antenna array 42 pieces While this antenna structure has less sensitivity than some large antennas, it is much more affordable in cost. The lack of sensitivity is eliminated by using antennas in combination. 20 antennas worked together to pick up Voyager I’s signal.

Voyager, which began its journey in 1977, must now use its power very sparingly, and scientists say the satellite will complete its life in 2025. Until now Jupiter, Saturn, Uranus, Neptune and the vehicle, which carries information by passing through many moons, also carries information about the world on it.
