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.

Ok don’t shoot me! You know I love a good petrol or diesel engine, but for £197 per month for a brand new Model 3, I just couldn’t resist getting one of these! It’s got to be the best value new car deal out there!
Time to see if you really can live with an EV!? (Alongside many ice vehicles).
Full off-road farm test coming soon! 😁
Ross Brawn returns to a motorsport role - but on two wheels.
He is joining Board of Directors of MotoGP squad Pramac Racing. He will act as strategic advisor to team boss Paolo Campinoti.
I’ve had the Renault 4 since Wednesday and I’ve been trying to think how I can offer something different to what ever other road tests have done?
Others are better at letting us know the real world range or how big the back seats are… so I settled on ‘What’s it like off road?’
Bear with me, as I’ve never made a car video with me talking in it before, plus I don’t have a camera man… Hope it’s not too amateur. Also, sorry Renault. 😬
@justchristwo I think they ruin your tyre and you need to replace it after. I used one many years ago and the gloop doesn’t always spread evenly so it goes out of balance. When I had my Volvo I invested in a spare wheel/jack/etc. felt much safer.
