EDIT: My personal observation is that this seems to be a picture of an object that seems to be displaying physical evidence that seems to suggest that it has impacted, or has been impacted, by another object.
I cannot personally prove that this is "What happens to a solid block of aluminum when a 0.5 ounce piece of plastic hits it at 15,000mph in space.", as the picture was titled.

Those Space Station astronauts gotta stop dumping their used plastic straws through the "space cat" door (or whatever hatch they use) and putting that stuff into orbit.
IIRC that block was not in space, it was a test here on the ground.
Also the reason they generally do not have to worry about this too much is because 99% of the stuff we launch goes in the same direction at the same altitude. Polar orbits(North-South) vs a "Normal" Orbit(East-West) often exist at different altitudes.
It is incredibly hard to launch something going the opposite direction from most satellites, hence why it is not done.
Ive seen some weird stuff from tornadoes. In Okla City I saw straws stuck into trees and sides of houses. Also saw a car in the top of a tree with the rear half twisted 90* to the front half like a wrung out rag. How about a complete house leveled except for the untouched bathroom. I didnt see it, but Ive seen pics and videos of the Xenia, Ohio tornado with semi trucks and railroad engines and cars flying thru the air for a few miles.

As with economics, politics, history, social issues, GPS and a whole host of other topics, your understanding of this subject is just as garbled, nonsensical and DEAD WRONG.

Spending just a little bit of a time researching this you will find that very few satellites travel in retrograde(against rotation, east -> west), the vast majority travel with the rotation of the earth. It is all about fuel savings.
No, most satellites are in a geo synchronized orbit so they go in the direction of rotation to stay positioned over the same spot....not to save fuel. Other satellites have orbits all over the place, some even have polar orbits that go over the north and south poles. The space station, and crew/supply rockets go opposite the rotation to gain speed faster. You can watch the station and shuttles fly by at nite from west to east on occasion.

I have actually watched ISS (International Space Station) pass 215 miles over my head at 17,200 mph as I lay amazed in the snow-covered Alaskan tundra.
It was brighter then the other points of light around it, and moving in a long, measured arch diagonally from horizon-to-horizon in a crystal-blue winter night sky.
How did I know that's what it was?
90 minutes later it did it again. And again 90 minutes later.
P.S. I should mention that I was very high...I mean, laying in the snow watching the stars for 3 hours.....but Math don't care.

I assumed we are only talking about orbiting satellites, as those are the areas where fast moving space debris are an issue. Many are in geo-sync orbit, but certainly not "most".
When they launch, they launch with the rotation of the earth because that is where they get the "boost" from already travelling the speed of the earths rotation. If they launch against the rotation, they have to overcome the rotational speed and achieve a speed necessary for orbit. Source(last paragraph). The ISS orbits with the rotation of earth.
