NASA sent a 13-billion-mile signal into space and … got a response
At a time when we do not occasionally have a signal here on Earth, NASA has been able to send a pulse to infinite distances and actually get a response.
It was not the beginning of a new friendship with an extraterrestrial culture, but a communication with Voyager 1, the only human creation that has reached so far in outer space, on the outskirts of our solar system.
Both Voyager 1 and his brother, Voyager 2, travel to the Universe carrying a small American flag as well as the infamous “Golden Record”, a ark of human covenant with sounds and images.
The US Space Agency was worried about some Voyager 1 propellers, whose operation has deteriorated, and said to roll a blind spot. To try to communicate with the backup, that is, by sending pulses of communication to something that has been working since 1980, and even in the inhospitable conditions of space. And he finally got the answer, as the propellers were activated!
According to a NASA statement, Suzanne Dodd, director of the Voyager team at Jet Propulsion Laboratory, said: “With these propellers that remain operational despite their 37 years of no use, we can extend the life of the Voyager 1 spacecraft by two with three years. “
Although it was essentially intercom, the fact that a pulse was sent so far and made things awake from a 37-year sleep was considered a triumph. And in terms of technology 1980.
