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.
After a decade of investigations targeting Donald Trump, Tulsi Gabbard unleashed the biggest counter coup in American history.
Now the hunted have become the hunters, and the hounds are about to be unleashed. This can change American politics forever.
On the 58th anniversary of my dadโs assassination, Iโm remembering moments like this: touch football on Cape Cod with my siblings โ David, Kathleen, Courtney, and me. #GetOutside#LiveRealLife
Everyone saw Trump drop f-bombs on Netanyahu and order him to stand down.
Almost no one saw what it proves: the President has slipped the leash the British Empire spent 80 years building. Why London is panicking ๐
.@JohnLeePettim13 congratulations on a life well spent. Similar path myself; now retired Millwright. Fortunately, many are now begging to see the value of the Trades.
A blonde is overweight, so her doctor puts her on a diet.
"I want you to eat regularly for two days, then skip a day, and repeat the procedure for two weeks. The next time I see you, you'll have lost at least five pounds."
When the blonde returns, she's lost nearly 20 pounds.
"Why, that's amazing!" the doctor says. "Did you follow my instructions?"
The blonde nods. "I'll tell you, though, I thought I was going to drop dead that third day."
"From hunger, you mean?" said the doctor.
"No, from skipping," replied the blonde
Did them all, plus #21-Used string and 2 tin cans to send and receive messages. #22-Climbed rope 30' up with hands/arms only. #23-Build skateboard from old metal roller skate, and lots more .
