The work of astrodynamicist Aaron Rosengren, an assistant professor in the Department of Aerospace and Mechanical Engineering, is featured extensively in a Nature article, published Sep. 5, 2018, describing threats posed by 20,000 objects orbiting Earth.
Rosengren’s idea is to use a web of gravitational phenomena known as “resonances” to remove dead satellites and other junk from orbit.
Other researchers have explored the concept before, but Rosengren is trying to push it into the mainstream. “It’s one of the newer things in space debris,” he says.
We call it passive disposal through resonances and instabilities. Yeah, we need a new name.”
