CNBC: Why SpaceX And Amazon Are Launching 42,000+ Satellites

Since the start of the space age, more than 8,800 objects have been launched into orbit, according to estimates from the United Nations Office for Outer Space Affairs. But in a few years, that number could increase significantly. Private companies plan to launch thousands of satellites to beam the internet to customers on Earth. SpaceX alone has announced plans to launch 42,000 satellites. If this happens, SpaceX will be responsible for about a fivefold increase in the number of spacecraft launched by all of humanity.
