You think maybe they lowered a bucket and the moon rocks just jumped in?
You know what makes them moon rocks, don't you? It's not just that they came from the moon. They are ancient rocks.
We don't have rocks that old here on Earth. They get churned through tectonic activity. The oldest rocks we can find are scarcely older than three billion years. Life was old when they were laid down.
But some moon rocks are from the original composition. It's the control for what the experiment called life has done to minerals on this planet.
And good night, Al Shepard. You were a true character, like NicknamedBob.
Yes, we do - you might see them in the sky at night - some call them "shooting stars" - little chucks of rock that usually burn up in the atmosphere...
