NASA confirms Earth's ambipolar electric field exists

A NASA rocket has confirmed the existence of Earth's ambipolar electric field, a weak global electric field surrounding the planet. This field, measured at 0.55 volts, influences the polar wind, facilitating the escape of ions from the atmosphere. The discovery, published in *Nature*, enhances understanding of atmospheric dynamics and could have implications for planetary habitability. The Endurance mission launched on May 22, 2022, from Svalbard, Norway.
