Voyager 1 is 24 billion kilometers from Earth.
It communicates with us using a 23-watt transmitter.
Less than a refrigerator light bulb.
The signal takes 22 hours to reach us, traveling at the speed of light.
By the time it arrives, it's 20 billion times weaker than the power of a digital watch battery.
NASA's Deep Space Network picks it up using 70-meter dish antennas cooled to near absolute zero to reduce electronic noise.
The engineering required to hear a 23-watt signal from 24 billion km away is arguably more impressive than the spacecraft itself.
Launched 1977.
Still transmitting.
Still being heard.
We built something that works perfectly, 47 years later, in conditions no one has ever tested in.
That's what engineering for the long term looks like.
@IV_Musketeer@Apple Imagine every Indian and Pakistani buying cables every time they break it.
Oceans will colapse in days, or houres
Big Thanks to bluetooth 💙
@guardiacivil Todo es delito en España. Solo es legal cuando los funcionarios te quitan las cosas que has ganado con tu sudor, o si lo hase un Magrebie.
@daniesdsk@lifeprospain Lo siento pero es incomodo mirar videos en Youtube. Muchos anuncios y nunca enseñana nada util. Me tendre que quedar sin este Desokupa News 😔

@Futbolitika@HenMazzig Have you ever seen Zionist set Paris on fire for a football match waving africans flags?
( a football match is a game with 22 monkyes runing behind a ball)
(Africa is a continent)
(Paris is a city in France, Europe)
