With Ever More Satellites Being Launched Each Year, The Risk Of Collisions And The Proliferation Of Space Debris Continues To Rise.
In Early 2022, Space Organizations Will Be Able To Give Their Missions, Including Satellite Launches And Crewed Missions, Certifications For Sustainability With The Finalization Of The Space Sustainability Rating (SSR). With ever more satellites being launched each year, the risk of collisions and the proliferation of space debris continues to rise. This has created a need to find ways to maximize the long-term sustainability of the space environment and encourage responsible behaviour.
The SSR system aims to address these issues by quantifying the sustainable behaviour of space actors. These scores will be based on factors ranging from data sharing, choice of orbit, measures taken to avoid collisions, plans to de-orbit satellites on completion of missions, and even how well they can be detected and identified from Earth. The choice and characteristics of a launch provider will also have an impact on the score.
There will be bonus marks for adding optional elements, such as de-orbiting fixtures, which could be used for the active removal of the object once its operational lifetime has been fulfilled.
“The Forum is very glad to support such an innovative approach to a global challenge of space debris,” said Nikolai Khlystov, Lead for Mobility and Space, World Economic Forum. “Incentivizing better behaviour by having actors compete on sustainability will create a race to the top and eSpace at EPFL is a great organization to take the SSR to the next level.”
After a robust selection process involving close to 20 stakeholders, the EPFL Space Center (eSpace) at the Swiss Federal Institute of Technology Lausanne (EPFL), based in Lausanne, has been selected to lead and operate the SSR, in preparation for the roll-out of the transparent system for scoring the space sustainability efforts of different space actors.
“Space sustainability is in eSpace’s DNA, as one of our research projects led to the creation of ClearSpace – a pioneer spin-off selected by ESA [European Space Agency] for the first debris removal mission. Hosting the SSR is a strategic move for our Center. With our experience and the partners that will support SSR at EPFL, Switzerland and international levels, we intend to initiate in 2022 what could be a game changer in the way space missions are carried out,” said Jean-Paul Kneib, Professor of Astrophysics and Director of eSpace.
“The SSR aims to influence behaviour by all spaceflight actors, especially commercial entities, and help bring into common usage the sustainable practices that we desperately require,” said Holger Krag, Head of ESA’s Space Safety Programme. “To achieve this, the SSR rating includes a peer-reviewed assessment of the short- and long-term risks that any mission presents to other operators and for our orbital environment in general.”
The SSR initiative was developed over the past two years by the Forum, the ESA and a joint team led by Space Enabled Research Group at the MIT Media Lab, with collaboration from BryceTech and the University of Texas at Austin, and it comes at a critical time. While satellites have long been used for navigation services, weather monitoring and television broadcasts, humankind’s reliance on space infrastructure is set to increase sharply with the launch of large constellations of small satellites designed to boost global internet access.
“The design process of the SSR catalysed a creative community of commercial firms, universities, government agencies and civil society organizations,” said Danielle Wood, Director of the Space Enabled Research Group at the MIT Media Lab. “There is more important work to do in engineering research, policy-making and norm building to ensure that the global community can operate in space for decades to come. All of us who contributed to the SSR are committed to continuing this important work and we hope others will continue to join in.”
There are now nearly 4,000 active satellites in orbit, including the inhabited outposts of the International Space Station and the Tiangong Space Station, currently under construction. As many more organizations from many more countries prepare to launch new missions, this number is set to grow exponentially. The risk of collisions will inevitably increase and raise questions about the capacity of near-Earth orbit to accommodate so many objects safely and sustainably.
By voluntarily taking part in the new SSR system, spacecraft operators, launch service providers and satellite manufacturers will be able to secure one of four levels of certification which they can share externally to show their mission’s level of sustainability. This will increase transparency, without disclosing any mission-sensitive or proprietary information. The goal is to incentivize good behaviour by all space actors in addressing the problem of space debris. A favourable score for a particular rated party might, for example, result in lower insurance costs or improved funding conditions from financial backers.
Over the two-year development period of the SSR, numerous operators within the space industry have been engaged in the evolution of the rating system and there is already widespread interest in this new tool. Several companies, including Airbus, Astroscale, AXA XL, elseco, Lockheed Martin, Planet, SpaceX and Voyager Space Holdings, have actively supported the SSR concept and expressed interest in participating once it is publicly launched.
