Those two things are spacecraft--Voyager I and Voyager II--launched in 1977 and 1979 respectively. Voyager I, traveling at 31,000 miles-per-hour, is now about 18 billion miles from earth (Voyager II is a mere 2 billion miles behind) and flying out of our solar system past the sun and into deep space for at least 13,500 more light years. (A light year is 31,516,000 seconds x 180.000 miles per second... forever... or until the end of time--as Buzz Lightyear would say, "To Infinity and Beyond."
Yeah, yeah, you've heard the story... but have you really?
Here's a clip from television's 60 Minutes that will blow your mind, if you have a desire to be mind-blown! It's about 13 minutes long and you will have to watch two 30-second commercials but it is worth it.
To accomplish this 'eternal mission' in 1977, we used a primitive 'state-of-the-art' computer system that took up almost all of the large room it was housed in. Your smartphone is 10,000 times more powerful than that was. Then there were the human computers that put this thing all together. Here's my 2011 post with more information.
I have two more posts to follow on Voyager.
- A review of the Golden Record: The Sounds of Earth aboard each Voyager for the aliens who discover our spacecraft--if ever. These records have been made 'earthling viewable' and have just gone on sale to the public. You will see how Carl Sagan tried to relate to unknown beings to tell them our story. (Hint: Chuck Berry performing Johnny B. Goode is there as are hundreds of other photos and data that may surprise you.
- The backstory of Hidden Figures, the black women who were called 'computers' by their associates, because that's how it was done before today's computer age. One of them literally saved John Glenn's life by finding a calculation error in critical data.
