NASA Finally Discovers Earth’s Electrical Field After 60-Year Search
It’s been here since the beginning alongside gravity and magnetism.
After fifty years of speculation an elusive gaseous shroud around the earth has been traced.

This force is called the “polar wind” which you were able to make a clear analogy for how Earth’s atmosphere can quickly be stripped away above the north and south poles, which the paper agrees played a big part in forming the planet’s relatively thin outer atmosphere. As it was said by scientists, this field is as vital for our planet as gravity and magnetic field.
“This field is critical to teaching how our earth operates — it is as previous as time, space, and quantum mechanics or maybe more so than gravity or magnetism,” quoted Glyn Collinson of the Endurance, lead of scientific operations, NASA Goddard Space Flight Center, Maryland in a NASA contextualisation of the Endurance. Yes, it is weak and rather unnoticeable – but it is major – it equals gravity and in fact – it raises skies up. “
The field’s existence was initially proposed more than 60 years ago. Spacecraft flying above the polar regions of the Earth in the late 1960’s observed a continuous efflux of particles at supersonic velocities into space. That which scientists were aware that sunlight creates atmospheric particles to ‘erode’ into space, none of the debris note in the detection procedure was apparent to have been burnt.
“There had to be an attracting force that was pulling these particles out of the atmosphere,” Collinson said in the statement to NASA. But measuring this barely perceptible and extremely feeble field the change in which would only be noticeable over hundreds of miles, was something that the given technology of the time was incapable of.
According to Collinson and his team, they started to work on sensors for the international Endurance sounding rocket mission in 2016. For example, in May 2022 an electron suborbital rocket with eight Specific Instruments was launched from Svalbard Rocket Range in Sweden a few hundred of kilometres to the North Pole. That place provided perfect premise for observation of this rather unprecedented meteorological phenomenon.
“Svalbard is unique worldwide because it is the only rocket range where you can fly through the polar wind and make the measurements that we required,” said Suzie Imber, a specialist in space physics at the University of Leicester in the UK.

Endurance rocket was in flight for approximately twenty minutes and it attained an apogee of about 477 miles (768 kilometers) while it collected information at an altitude of 322 miles (518-kilometers) of atmosphere. It got a brief 0. 55-volt change — “almost nothing, only as strong as a watch battery,” said Collinson. “Well, that simply is sufficient to explain the polar wind. ”
Astronomers think the field starts around 250 km or 150 miles from the surface of the Earth where gases in the stratosphere decompose into electrons and ions. An electric field is created between these particles; this repels gravity and free a number of these particles into space.
The researchers learned that while the polar wind is invigorated by hydrogen ions, these particular ions are pushed outwards by the field 10. 637,000,000 times stronger than gravity — that would be enough to propel them into space at supersonic velocities. The polar wind also gives a speed increase to oxygen ions, which are heavier than hydrogen ions. This makes it look like a conveyor belt that will lift the atmosphere into space Collinson noted.
Since the polar wind is generated by dynamics far beneath the surface of our planet, researchers believe that such fields will be present on other planets such as Venus and Mars. Future research over this idea will help in finding its effect in altering the atmospheric composition of the Earth and the consequences it had on the formation of our oceans.
“This field is a fundamental part of how Earth works, and now that we have actually measured it we can start asking other questions that are much more tantalising. ”
The findings were detailed in a paper published on Wednesday, Aug. 28, in the journal Nature.
