Space debris — detritus orbiting Earth by satellites — can be a growing problem which threatens the future of human space exploration.
To tackle This particular issue, the Business Secretary Alok Sharma has announced £1million in funding, via the UK Space Agency (UKSA), for seven space-cleaning programmes.
Astronomers are concerned in which high-value craft in low-Earth orbit, such as the International Space Station (ISS), could be destroyed by a rogue piece of debris.
Currently, there can be no way of accurately monitoring in addition to tracking modest pieces of debris which could be hurtling towards a multi-million pound satellite.

Seven programmes to clear space debris
Working on photonic technologies to spot items in orbit in addition to tell if they are junk or satellite.
This particular project focuses on the design, prototyping in addition to demonstration of a Low-Cost Low-Earth Orbit Optical Surveillance Sensor.
A ’40×40 squared degrees one-eye’ prototype will be built.
inside final solution, ‘9 eyes’ will be combined.
Lift Me Off
Project will create an AI-powered algorithm in which can differentiate between junk in addition to actual satellites.
Tweak in addition to repurpose existing sensors to spot in addition to identify objects moving around a spacecraft.
Fujitsu in addition to Amazon
Fujitsu in addition to Amazon will develop machine-learning methods to integrate planning for space debris into existing missions.
Mr Sharma said This particular will improve the commercial viability of missions in which seek to remove debris.
The project will rapidly design in addition to deploy an extremely low-cost prototype optical camera system to track objects in Low Earth Orbit.
Will make ‘significant improvements’ to Andor’s existing Balor very large area (17 megapixel / 70mm diagonal) scientific CMOS camera.
The proposed project will significantly increase Balor’s sensitivity resulting in considerably faster imaging in addition to/or enabling the tracking of smaller in-orbit debris.
in which can be believed there are around 160million pieces of debris floating around Earth, trapped in our planet’s gravity in addition to travelling at 18,000mph.
Of these, almost one million are believed to be larger than 1cm. If one of these were to collide which has a satellite the damage would certainly be devastating.
Not only would certainly in which destroy the craft, in which would certainly likely set off a chain reaction, seeing innumerable satellites knocked out of action.
This particular would certainly have catastrophic implications for life on Earth, as modern society relies on satellite services for GPS, mobile communications in addition to weather forecasting.
‘Millions of pieces of space junk orbiting the earth present a significant threat to UK satellite systems which provide the vital services in which we all take for granted – by mobile communications to weather forecasting,’ says Business Secretary Alok Sharma.
He told The Telegraph in which action to clean up space must be taken at This particular point, before in which can be too late.
‘If we don’t take action at This particular point, low-Earth orbit could become too perilous for satellites or even humans on the International Space Station,’ he said.
Currently, there can be no way to remove space debris, in addition to only the biggest items in orbit can be spotted.
in which can be hoped the £1million funding will help make This particular possible by the UK.
in which has been allocated to seven different projects, each which has a unique plan to improve our understanding of our mucky orbit.
One project, dubbed ‘Life Me Off’, will create an AI-powered algorithm in which can differentiate between junk in addition to actual satellites.
Another, called Lumi Space, will use lasers to track in addition to map the objects.
These seven made the cut by a total of 26 proposals, the UKSA says.
Graham Turnock, Chief Executive of the UK Space Agency said: ‘People probably do not realise just how cluttered space can be.
‘You would certainly never let a car drive down a motorway full of broken glass in addition to wreckages, in addition to yet This particular can be what satellites in addition to the Space Station have to navigate every day in their orbital lanes.
‘In This particular brand-new age of space megaconstellations the UK has an unmissable opportunity to lead the way in monitoring in addition to tackling This particular space junk.
‘This particular funding will help us grasp This particular opportunity in addition to in doing so create sought after expertise in addition to brand-new high skill jobs across the country.’
To tackle the issue of space debris, the Business Secretary Alok Sharma (pictured on Monday arriving in Downing Street) has announced £1million in funding, via the UK Space Agency (UKSA), for seven space-cleaning programmes.
While the government funding will help astronomers identify space junk in addition to avoid collisions, plans are also afoot to actively remove space debris.
Swiss firm ClearSpace received the go-ahead by ESA for a £100million mission to build a space ‘tow truck’ designed to remove dead satellites by Earth’s orbit.
British engineers at aviation giant Airbus created a space harpoon in which could help capture rogue satellites in addition to pull them back down to Earth.
The 3ft (95 cm) missile would certainly be fired by a ‘hunter-killer’ spacecraft, which would certainly pull in which – in addition to its prey – back using a cord.
A Russian startup hopes a foam-spewing spacecraft in which catches debris like a spider web in addition to tosses them into Earth’s atmosphere to burn up could be the solution.
StartRocket can be developing a ‘Foam Debris Catcher,’ which can be a series of modest in addition to autonomous satellites in which collects in addition to de-orbits space junk using a sticky polymer foam.
WHAT can be SPACE JUNK? MORE THAN 170 MILLION PIECES OF DEAD SATELLITES, SPENT ROCKETS in addition to FLAKES OF PAINT POSE ‘THREAT’ TO SPACE INDUSTRY
There are an estimated 170 million pieces of so-called ‘space junk’ – left behind after missions in which can be as big as spent rocket stages or as modest as paint flakes – in orbit alongside some US$700 billion (£555bn) of space infrastructure.
although only 22,000 are tracked, in addition to with the fragments able to travel at speeds above 16,777 mph (27,000kmh), even tiny pieces could seriously damage or destroy satellites.
However, traditional gripping methods don’t work in space, as suction cups do not function in a vacuum in addition to temperatures are too cold for substances like tape in addition to glue.
Grippers based around magnets are useless because most of the debris in orbit around Earth can be not magnetic.

Most proposed solutions, including debris harpoons, either require or cause forceful interaction with the debris, which could push those objects in unintended, unpredictable directions.
Scientists point to two events in which have badly worsened the problem of space junk.
The first was in February 2009, when an Iridium telecoms satellite in addition to Kosmos-2251, a Russian military satellite, accidentally collided.
The second was in January 2007, when China tested an anti-satellite weapon on an old Fengyun weather satellite.
Experts also pointed to two sites in which have become worryingly cluttered.
One can be low Earth orbit which can be used by satnav satellites, the ISS, China’s manned missions in addition to the Hubble telescope, among others.
The various other can be in geostationary orbit, in addition to can be used by communications, weather in addition to surveillance satellites in which must maintain a fixed position relative to Earth.
