The new prime real estate? Earth’s orbit

There are 15,000 satellites orbiting planet Earth. Just one accident could be calamitous. Jonathan O'Callaghan joins host Krys Boyd to discuss the enormous numbers of satellites being launched into space, what this means for traffic at low-Earth orbit altitude and space trash, and why, despite concerns, there are plans to launch 2 million more in the next few years. His article “Battle for the Night Sky” appears in Scientific American.
