In 1978, NASA researcher Donald Kessler and his colleagues published a paper titled "Collision frequency of artificial satellites: The creation of a debris belt." The paper laid down a grim warning: a single collision between satellites that would escalate into a series of followup accidents, "each of which would increase the probability of further collisions, leading to the growth of a belt of debris around the Earth." "Under certain conditions, the belt could begin to form within this century and could be a significant problem during the next century," the prescient paper warned.
Securing a conversation with Leonidas Askianakis requires foresight. His schedule is carved into 30-minute slots from 5 a.m. until 11 p.m. Meetings are online only, and every one of them revolves around space.
