Satellites, that is...
Miles and miles above the ground, thousands of metal bodies with specialized instruments orbit our blue and green marble of a world, taking photos, surveying weather phenomena, and even providing amateurs with extraterrestrial repeater service!
With that being said, I can't emphasize how many orbit the earth - there are so many that concerns have been raised about the threat of space debris falling from the sky. In recent months, space debris from old satellites have fallen from the sky, and in rare but not impossible instances, they have ended up in someone's home.
However, some of these pieces of space junk have been found to be fully alive! After 40, 50, and even 60 years, some satellites just spring back to life. Below are a few examples of ones I've found - and heard!!!
