As the US Space Force nears its third birthday, John Amble is joined by Dr. Moriba Jah on this episode to explore just how crowded the space domain is—especially with the surprising amount of detritus created over more than six decades of the Space Age. Dr. Jah is an aerospace engineer who has worked for NASA and the Air Force Research Laboratory. He is now an associate professor at the University of Texas, where he monitors space and works to track thousands of objects—a number that continues to grow—orbiting Earth.
