International Space Station could be fitted with huge lasers to shoot down space junk
Space debris poses a huge risk to the satellites that are in space and power much of communication on Earth

From reproductive rights to climate change to Big Tech, The Independent is on the ground when the story is developing. Whether it's investigating the financials of Elon Musk's pro-Trump PAC or producing our latest documentary, 'The A Word', which shines a light on the American women fighting for reproductive rights, we know how important it is to parse out the facts from the messaging.

And unlike many other quality news outlets, we choose not to lock Americans out of our reporting and analysis with paywalls. We believe quality journalism should be available to everyone, paid for by those who can afford it.
Your support makes all the difference.Scientists want to fit huge lasers to the International Space Station (ISS) and use them to blast away the estimated 3,000 tons of space debris that flies around the Earth and could be putting it in danger.
The plan, proposed by researchers from the Riken Institute in Japan, would see the Extreme Universe Space Observatory (EUSO) telescope that is currently fitted to the ISS converted into a tool for spotting space debris. When that spots a piece of dangerous debris, a laser would be used to fire at bits of space junk until it goes out of orbit and burns up as it goes back towards the Earth.
The team behind the laser plan hope that they can test it out with a small telescope and laser on board the ISS. If that works, scientists hope to put a full version on the ISS.
The team hope that the final version will use a three-meter telescope and a laser built out of 10,000 fibres. That would be able to shoot down space junk from about 100 kilometres.
The team say that if the laser installed on the ISS worked, a devoted one could be sent out into space, towards the altitudes where most of the dangerous debris is.
