Less than a year after the UK Space Agency pledged £ 1 million to combat space debris, Fujitsu UK has successfully combined quantum computing and artificial intelligence to support the transformation of its debris removal system.

Fujitsu Prototype – Created in collaboration with Glasgow University, Amazon Web Services and Astroscale UK will improve mission planning so that a single spacecraft can efficiently choose which pieces of space debris to remove in a single mission, much faster than is currently possible.

Removing space debris is key to sustainability in space, reducing or even preventing the risk of legacy spacecraft colliding with new and existing satellites.

What’s more, supporting debris removal missions with Fujitsu technology will help reduce the risk of catastrophic collisions in orbit, which could lead to thousands of other new debris that pose a real threat to operational satellites in orbit.

By carefully deciding what debris and when to collect, Digital Annealer’s quantum proposal optimizes a mission plan to determine the minimum fuel and minimum time needed to safely return a failed spacecraft or satellites to disposal orbit. Finding the optimal route for collecting space debris will significantly save time and money during the mission planning phase, as well as, as a result, increase commercial profitability.

With 2350 inoperative satellites Currently in orbit and more than 28,000 debris tracked by space surveillance networks, this technology will help the UK increase its market share in the space sector. It will also further support the UK government’s commitment to a more sustainable future overall.

Dr. Matteo Ceriotti, professor of space engineering, and graduate student Julia Viavattene, who led the project for the University of Glasgow, said: “The University of Glasgow was involved in this project from the very beginning – developing the trajectory. the models needed to efficiently remove space debris as well as to estimate the cost of travel.

“The University has a long history of experience in the design and optimization of space trajectories, which is why we have strived to be at the forefront of any government initiative to enhance the UK’s image in the space sector. With the help of Fujitsu, AWS and Astroscale UK, we have helped overcome the challenges of removing space debris to make future projects easier. ”

Ellen Devereux, digital firing consultant for Fujitsu UK and Ireland, said: “All space debris presents a potential risk of collision with operating systems that many of us take for granted, from weather forecasts to telecommunications.

“With the support of the UK Space Agency, Astroscale UK, AWS and the University of Glasgow, we have developed a solution to optimize the planning of a maintenance ship’s mission before it goes into space. This means that organizations like Astroscale UK can choose to collect more trash faster than ever before.

“This not only makes the process much more cost-effective for organizations that need to move and dispose of garbage, but it also leverages artificial intelligence and quantum computing.

“Over the past six months, we have learned that this technology has tremendous value for optimization in space; not only for garbage collection, but also for in-orbit maintenance and more. We now understand its potential better, and we can’t wait to see how the technology will be applied during the future mission. ”

Jacob Gere, head of space surveillance and tracking at the UK space agency, said: “Monitoring dangerous space objects is vital to protect the services we all rely on, from communications devices to satellite navigation. This project is one of the first examples of the use of quantum computing and artificial intelligence to solve space debris problems, but it is unlikely to be the last.

“The UK is committed to making space sustainable, and Fujitsu, working with Astroscale UK, the University of Glasgow and AWS, has demonstrated the real value of keeping space uncluttered by making it accessible to future generations.”

Stephen Vox, CTO at Astroscale UK, said: “Finding the optimal mission plan manually is time consuming and difficult. Astroscale UK is leading the next pioneering move under the End-of-Life Services by Astroscale (ELSA) program to remove not only one piece of debris, but multiple objects of debris with a single serving satellite known as ELSA-M, which is essentially a more economical way to remove debris from orbit. By teaming up with Fujitsu, AWS and the University of Glasgow, we hope to further optimize this for future missions. ”

The study was carried out under a grant from the UK Space Agency “Expanding Space Surveillance and Tracking Research”. The project, which was developed over six months in accordance with government digital services guidelines, uses fast technologies based on an artificial neural network (ANN). Trajectory design algorithms developed by the University of Glasgow, together with Fujitsu Digital Annealer and Quantum Inspired Optimization Services, to address some of the major optimization problems associated with Active Debris Removal (ADR) mission planning.

Amazon Web Services provided Cloud and AI and ML tools and services to support the project. The Amazon Sagemaker toolbox has been used to rapidly develop ANNs that accurately predict the cost of orbital movements in a fraction of the time required to fully calculate them. Astroscale UK, the world’s first commercial company to embark on a debris removal demonstration mission from lower Earth orbit, offers an end-use case as a typical user of multi-mission optimization.

Fujitsu, which spearheaded the project, is one of seven UK companies to receive more than £ 1 million in space debris tracking from the UK Space Agency. The UK Space Agency and the Department of Defense have announced the next step in their joint initiative to raise UK awareness of events in space.

Anti-vaccinators use Instagram Stories and link stickers to spread misinformation

Anti-vaccinators use Instagram Stories and link stickers to spread misinformation


How do anti-vaccinators fund their dangerous movement with so many online platforms that ban false information against vaccinations?

According to a new report, Instagram Stories is one of the main outlets Media issues.

The report found “dozens of examples of users” who have armed Facebook’s Stories feature to sell products, promote events and even redirect Instagram users to alternative social media platforms, where they can’t be banned.

This is a special feature that the Media Matters report focuses on.link stickers”it spread to all users of Instagram late last year.

Link stickers allow users to add a link to a third party website to the Stories content. For years, Instagram has avoided allowing off-platform links, except for one link that allows users to add to their profile page. Link stickers eventually gave users this feature, as well as gave antivaxers a way to profit from their accounts.

On Instagram Terms of serviceThe platform will remove the ability to publish account stickers if they “repeatedly share things like hate speech and misinformation or other content that violates our Community Rules”.

However, because Instagram events are ephemeral, they disappear after 24 hours, and antivaxists, conspiracy theorists, and malicious users can spread malicious misinformation and links to their followers.

In addition, some anti-vaccinators who use these methods on Instagram are using backup accounts, which can only be temporary. Suspension, removal of features, or other penalties for violating Instagram policies may work with most bona fide users, but antivaxers do not work in good faith. Many are using the accounts created to avoid the ban, disseminate misinformation against vaccinations through Instagram Stories, and link the stickers as quickly as possible until the last Instagram account is closed.

Instagram has been battling antivaxes on its platform for many years. The company has taken some measures against misinformation about the vaccine, such as banning hashtags related to antivax, good nose even the COVID-19 pandemic. Still, Instagram continues to provide the most productive stuff anti-vaxxer agents in motion with the platform. The Instagram Stories and link stickers feature provides a lifeline for these users, even though Instagram has banned their main accounts.

The stories and link stickers used to spread misinformation about the vaccine are another example of how antivaxers use all the tools at their disposal to tell the story they want to tell, despite the truth.

UPDATE: January 27, 2022, 3:00 p.m. EST An Instagram spokeswoman told Mashable that the company had taken action against two prominent anti-waxes on its platform: Joseph Mercola and Sherry Tenpenny, both of whom were named in the Media Matters report. The full Instagram post is below: “We do not allow people to share posts or links that block vaccines or share incorrect information about COVID-19. We removed @ drtpenny_official for violating our rules, removed two posts from @ drmercola and hacked the #plandemic hash.”
