The Ionization Challenge: How the Sun Sinks Satellites and How Electric Propulsion Can Save Them There is a fascinating, almost poetic irony unfolding in low-Earth orbit right now. The very phenomenon that paints the night sky in the spectacular greens and purples of the Aurora Borealis is the same force threatening to drag the Swift Observatory out of orbit. The proposed solution is a spacecraft named LINK that uses the exact same physical principle—ionization—to push Swift back to safety. At the heart of this story is ionization. In the context of space, this isn't about the change of state of molecules in chemistry; it’s about mass and motion. Broadly, ionization is the process of stripping electrons from atoms, turning neutral gas into a plasma of charged particles. A single concept links three distinct events reported in the news: 1) a solar storm, 2) a glowing sky, and, 3) a satellite rescue mission. 1. The Problem: Solar Storms and the Expanding Atmosphere It all starts with...
