Scientists have issued a stark warning to humanity in terms of the Kessler syndrome that would ship humanity again to the metaphorical Dark Ages if it comes true.
Modern society is stuffed with technical wonders that we do not even realise make every thing tick alongside properly.
From utilizing GPS to make planes run like clockwork to mapping climate to make sure world meals manufacturing retains humanity fed, there are many nuanced methods fashionable life works with out even realising.
But it may all be at main danger of grinding to a halt if the Kessler syndrome comes true. And now, a recent warning has been issued over the hazard it poses.
Kessler syndrome definition
First theorised again in 1978, the Kessler syndrome was thought up by NASA scientists Donald Kessler and Burton Cour-Palais.
Their speculation was that if humanity retains flooding the world of area round Earth – generally known as low Earth orbit (LEO) – with increasingly satellites and area junk, it will quickly get crowded to a degree the place issues may get actually dangerous for individuals.
Kessler and Cour-Palais mentioned that if we preserve sending stuff in to area to orbit across the planet, it is going to attain a saturation level the place collisions start and can’t be stopped.
NASA says: “Spent rockets, satellites and different area trash have amassed in orbit growing the probability of collision with different particles.
“Unfortunately, collisions create extra particles making a runaway chain response of collisions and extra particles generally known as the Kessler Syndrome after the person who first proposed the difficulty, Donald Kessler.”

New Kessler syndrome warning
Dan Baker, director of the Laboratory for Atmospheric and Space Physics on the University of Colorado, issued a recent warning over the Kessler syndrome at a 2024 assembly of the American Geophysical Union in Washington DC.
As of 2024, there are greater than 10,000 energetic satellites orbiting the planet, with round 6,800 of them belonging to Elon Musk and his Starlink broadband community.
And it may get much more crowded, with greater than 40,000 satellites needed as a part of Musk’s Starlink community.
On prime of the ten,000 present satellites, there are roughly 40,500 items of particles greater than 10 centimetres in size orbiting the Earth, in keeping with the European Space Agency (ESA).
With all this in thoughts, Baker informed the December assembly: “We must get severe about this and recognise that, except we do one thing, we’re in imminent hazard of constructing a complete a part of our Earth setting unusable.”
Space plasma physicist David Malaspina, an assistant professor on the University of Colorado, added: “If the Kessler syndrome begins to occur and we begin to see a form of cascade of collisions, we’ll see it within the smallest grains first. These are our canary within the coal mine.”

What will occur if the Kessler syndrome comes true?
If a series response of collisions occurs round Earth involving satellites, life on the planet may change shortly.
Satellites could be taken out and a end result humanity would undergo big web and Wi-Fi outages. Phone networks would go down with no satellites within the sky to ping calls from. It would even imply the potential finish of TV and GPS.
If that occurred, climate satellites could be taken out, impacting our capacity to trace its affect on plenty of industries comparable to meals manufacturing and fishing in addition to predict pure disasters and save lives.
The drawback in such a state of affairs is that there’s nothing to decelerate the chain response across the planet, making it extremely laborious to launch new satellites with out them additionally being taken out.

Stopping the Kessler syndrome
Right now, there are round 1,000 collision warnings on daily basis in terms of objects in low orbit of Earth, in keeping with Thomas Berger, director of University of Colorado’s Space Weather Technology Research and Education Center.
The drawback, Berger says, is that area is lawless in terms of satellite tv for pc and sending extra up there.
Attention has turned to methods of recycling what’s already in area, with particles probably being reused for brand spanking new initiatives. Some have checked out burning up gadgets in Earth’s ambiance, however that is one which carries warning, with such acts depleting the ozone layer.
Clearly, in keeping with the specialists, we now have to behave quick. And these with the cash and political energy to take action have that accountability firmly on their shoulders.
