Fifty years ago today, Telstar, the world’s first active communication satellite was launched into outer space. The tiny device, just three-feet long, was the first to send television signals, telephone calls, and fax images through space.
In the last five decades, the world’s countries have launched hundreds of satellites, and we now have approximately 3,000 in Earth’s orbit. Unfortunately, old, useless satellites are still up there, as are spent rocket stages and other random man-made things. In all, there are approximately 8,000 objects circling the globe. This space junk has turned out to be a huge problem.
