The British government pledged a million pounds ($1.3 million) on Wednesday to tackle dangerous “space junk,” which could crash into active satellites and disrupt key services like mobile phones and weather forecasting.
Seven UK companies will share the million pounds to develop tracking technologies to monitor the orbiting debris, the UK Space Agency said in a media release.
Some space debris can be detected by functioning satellites, but only a fraction of the total can currently be tracked. The technologies will help avoid collisions with operating satellites, and even with the manned International Space Station, the UK Space Agency said.
“Last year there was a close call in which a £100 million [$130 million] spacecraft operated by the European Space Agency (ESA) had to light up its thrusters to dodge a satellite,” the agency said.
The new technologies will include artificial intelligence and sensors to monitor anything in orbit over 1 centimeter (0.4 inches) in size. There are up to 160 million objects currently orbiting the Earth, an estimated 900,000 of which are larger than 1 centimeter.
“The UK has a significant opportunity to benefit from the new age of satellite megaconstellations—vast networks made up of hundreds or even thousands of spacecraft—so it is more important than ever to effectively track this debris,” The UK Space Agency said.
In 2018, the ESA highlighted the importance of avoiding space collisions as satellite mega-constellations become a commonplace solution for global telecommunications coverage.
The ESA likened the orbits of space objects to the movement of traffic on roads.
“Like roads on Earth, these space highways are becoming increasingly congested with operational spacecraft, dead spacecraft and space debris, increasing the likelihood of collisions,” the ESA said.
Helping Small Business
One of the pioneering projects being backed by the government is from Lift Me Off, a two-year-old company of only five people.
By using cameras in space and applying “future recognition software,” patterns in data from the sensors would show whether an orbiting object is a satellite or space debris, Lift Me Off CEO Michel Poucet told The Epoch Times in an interview.
If it’s a satellite, the team could then identify if it’s a functioning satellite or not, Poucet said, and from there assess the risk to other satellites and warn interested parties.
“If it’s a defunct satellite that another country put up and we weren’t aware of, we can provide that information to the UK government or other governments or commercial operators and tell them, ‘Oh, watch out we have spotted an object—it looks like a satellite but it doesn’t seem to be functioning, it doesn’t give the standard footprint.’ We can then give a warning,” he explained.
Poucet said Lift Me Off appreciated the UK Space Agency’s backing of new and smaller companies.
“We are not a big company, we are five people. We started two years ago. We thought of new things and the challenges of the future. This was one of them, and the UK Space Agency acknowledges that and also that there are new companies out there that have new technologies that can enhance capability,” he said.
“It is giving us a chance.”
Other companies receiving the government backing include Deimos, who will be looking at designing and creating a prototype Optical Surveillance Sensor, and NORSS, who will research the quick design and deployment of a low-cost space camera system to track objects that are orbiting relatively close to the Earth.
UK Business Secretary Alok Sharma said the government backing would not only protect relied-upon services but also have the knock-on effect of creating new employment.
“By developing new AI and sensor technology, the seven pioneering space projects we are backing today will significantly strengthen the UK’s capabilities to monitor these hazardous space objects, helping to create new jobs and protect the services we rely on in our everyday lives,” he said in a statement.
Chief Executive of the UK Space Agency Graham Turnock said people were not generally aware of the amount of space junk that is orbiting the planet.
“You would never let a car drive down a motorway full of broken glass and wreckages, and yet this is what satellites and the space station have to navigate every day in their orbital lanes,” he said.
Turnock also said the UK had an “unmissable opportunity to lead the way” with tracking and tackling space junk.
The new funding will also help “create sought after expertise and new high skill jobs across the country,” he added.
