Has NASA finally detected the invisible electric field pulling particles from our atmosphere?
For nearly 60 years, scientists have theorized that a weak, planet-wide electric field drives the polar wind—a steady stream of particles escaping Earth's atmosphere. This video details the 2022 NASA Endurance mission, which traveled to Svalbard to attempt the first-ever measurement of this elusive phenomenon.
The polar wind consists of particles flowing from Earth's atmosphere into space above the North and South Poles. While researchers long suspected an 'ambipolar' electric field was responsible for this outflow, the field's extreme weakness made it impossible to detect with previous spacecraft technology.
To solve this, the NASA Endurance mission launched a rocket from Svalbard, Norway, in 2022. By targeting this specific region, the team sought to confirm the existence of the field that has remained a mystery for six decades.
