It's called the ambipolar field, an electric field first hypothesized more than 60 years ago, and its discovery will change the way we study and understand the behavior and evolution of our beautiful, ever-changing world.
Earth isn't just a blob of dirt sitting inert in space. It's surrounded by all sorts of fields. There's the gravity field. We don't know a lot, especially considering how ubiquitous it is, but without gravity we wouldn't have a planet. Gravity also helps keep the atmosphere snug against the surface., which is generated by the rotating, conducting material in Earth's interior, converting kinetic energy into the magnetic field that spins out into space.
This is called the ambipolar field because it works in both directions, with the ions supplying a downward pull and the electrons an upward one. This ambipolar field would be incredibly weak, which is why Collinson and his team designed instrumentation to detect it. Themission, carrying this experiment, was launched in May 2022, reaching an altitude of 768.03 kilometers before falling back to Earth with its precious, hard-won data.
