A University of Utah professor has warned that of the hundreds of millions of fragments floating in space, a significant portion could form a ‘ring’ around Earth, similar to the solar system’s gas giants.
University of Utah researcher Jake Abbott said in a recent interview that the debris is likely to give Earth ‘rings of its own’ made of ‘space junk’. Salt Lake Tribune,
However, Abbott and his team are working on a way to clean up the debris, placing a magnet on the end of the robotic arm and using the magnet’s eddy currents to collect space garbage.
NASA an estimate There are at least 23,000 pieces of debris that entered low-Earth orbit (LEO) larger than a softball in orbit, but there are probably 500,000 pieces between 0.4 inches and four inches apart.
It is possible that there are 170 million pieces of space debris that are smaller than 0.4 inches, the European Space Agency couple,

Saturn’s rings are made of ice and rock, which vary in size, and may be the remains of ancient comets, asteroids or celestial satellites.
More than 27,000 pieces of orbital debris are tracked by the Department of Defense’s Global Space Surveillance Network sensors.
Four planets in the Solar System already have rings – Jupiter, Saturn, Neptune and Uranus.
Saturn’s rings are made of ice and rock, which vary in size, and may be the remains of ancient comets, asteroids or celestial satellites, NASA Note,
The rings that orbit Jupiter and Neptune are quite faint and made up mainly of dust.
It is possible that Jupiter’s rings may have stemmed from multiple meteor strikes that struck the planet’s 79 moons, according to Royal Museum Greenwich,
NASA telling That LEO is now seen as the ‘world’s largest garbage dump’, adding that space debris is expensive to remove because of the size of the problem – there could be 6,000 tons of material in low Earth orbit.
A lot of space debris can reach extremely high speeds (in some cases, up to 18,000 mph or seven times the speed of a bullet), ‘the impact of even a small piece of orbital debris hitting a spacecraft or Earth’ will cause major problems. can cause. ,’ NASA said.
Abbott is working on a way to clean more than 6,000 tons of material in low Earth orbit, most of which is flying at 15,700 mph.
Abbott told the news outlet, ‘Most of it is moving junk. ‘Reach out to stop it with a robotic arm, you’ll break the arm and create more debris.’
To clean this up, he and his team are working on a way to use magnets to clean LEO of all debris using eddy currents.
“We basically built the world’s first tractor beam,” Abbott explained.
‘It’s just a question of engineering. Build and launch it.

As the magnets spin, they activate eddy currents (electric currents that are whirlpool-shaped) that create their own magnetic field.
Ultimately, space debris can be collected, using the magnetic field of currents.
‘Using dimensional analysis, along with multiphysics numerical simulations and experimental verification, we characterize the forces and torques generated on a conductive field in a rotating magnetic dipole field,’ the authors write in the study’s abstract.
Other groups are also working to reduce the burden posed by the massive amount of debris, which mostly consists of satellites and spacecraft.
Privateer, a space startup backed by Apple co-founder Steve Wozniak, told DailyMail.com that the firm is attempting to track space junk in orbit and predict how it will function and make space safer for all nations. Where will you travel to?
“The idea is to make space more transparent, make it more predictable, knowing exactly where the space junk will be in the next few minutes and hours,” Moriba Jah, the company’s chief science adviser, said in a phone interview.
‘We will be able to predict how two objects of two different governments will function before there is any cause for concern.’
Earlier this month, Russia blew up one of its own satellites and the resulting debris nearly reached the International Space Station.
US analysts believe that the country may have used the A-235 PL-19 Nudol ‘satellite killer’ missile to destroy Kosmos 1408.
When Kosmos 1408, a defunct spy satellite launched in 1982, was destroyed, it resulted in an area of 1,500 pieces threatening the crew of the ISS.
Some analysts have suggested that the space junk left over from the explosion would wreak havoc for the spacecraft for years, possibly decades.
The satellite was orbiting about 300 miles above Earth’s surface at the time, and created a debris field between 270 miles and 320 miles from the surface.
The ISS orbits about 260 miles above the surface, although at the time of the event, it was slightly less than 250 miles above the surface, meaning that debris passed about 20 miles above it as their orbits crossed.
