The story of these travelers is very interesting as each of the things that allow us to see how big the universe is and how small we are before its immensity. However I wonder if by launching this kind of objects that later cannot be recovered we are not contributing to dirty space? that is to say that these objects in the end become space debris, isn't it?
Hi @emimoron, these probes have allowed us to know important aspects of our solar system, and well, two probes like these do not represent as much garbage as the amount of debris accumulated in the orbit of the earth, and perhaps with the passage of several hundred years will be reduced by ultraviolet radiation.
