Space Sustainability Rating: The New Look on Space Environment

The advancements in space technology and space applications have transformed our outlook on the universe. However, the question for its sustainability arises due to the number of factors influencing the space environment.

FREMONT, CA: Space science and space technology are of vital importance in elevating our knowledge of the universe. It has contributed to the advancement of meteorological forecasting, climate change, environmental monitoring, administer natural resources, satellite navigation, and early warning systems that support disaster control, which has saved many lives. The progression in this field will continue to help in the enhancement and discovery of the outer space environment.

With the advancements in space technology and the advantages it brings, it is also necessary to keep in mind the adverse effects that come with it, such as satellite debris. The need for preservation, protection, and sustainability of the outer space environment is an important concern that needs to be effectually addressed.

A team was created by the World Economic Forum (WEF) to create a rating to rate how well satellites follow and observe space sustainability guidelines, called "Space Sustainability Rating." This rating will evaluate the satellites according to their capability to guarantee the long-term sustainability of space. It is meant to generate a feeling of responsibility among the satellite operators, not through law or economics, but through social and peer pressure.

The rating system will include a mix of quantitative and qualitative measures depending on the satellite's design to avoid the risk of impact and the discarding of the satellite at the end of its life, to the economic survival of the satellite operator, in case the satellite outlasts the company that launched it. The ultimate rating will be a single number between zero and one; however the balancing of various factors will remain as a major challenge in front of the team. They planned to use a sensitivity test to figure out how the alteration in each factor influences the overall score.

The initial version of this rating system will be ready late this year or early 2021.
