A sustainability rating for space debris

In orbit around Earth today there are over 20,000 objects larger than 10 centimeters. A sustainability rating for space debris | MIT News sustainability rating for space debris Teams from the MIT Media Lab, European Space Agency, and World Economic Forum will create a rating system and global standards for space waste mitigation. Helen Knight | MIT Media Lab Of these, only about 2000 are operational satellites. Creating a Space Sustainability Rating - The Good Men Project Space Sustainability Rating will create an incentive for companies and governments operating satellites to take all the steps they can to reduce the creation of space debris,” Wood says. The remainder are space debris that create a hazard for the useful satellites that provide our global weather, navigation, and communication services.

Space is becoming increasingly congested, even as our societal dependence on space technology is greater than ever before.

With over 20,000 pieces of debris larger than 10 centimeters, including inactive satellites and discarded rocket parts hurtling around in Earth’s orbit, the risk of damaging collisions increases every year.

Space Sustainability Rating could help address space debris problem

In an effort to reduce the amount of space debris circling the Earth, the World Economic Forum and its partners are working on a Space Sustainability Rating (SSR) that will indicate how well satellite operators and launchers are complying with space debris mitigation guidelines. Consortium to develop “space sustainability” rating system ... space envision the Space Sustainability Rating to be similar to the Leadership in Energy and Environmental Design (LEED) systems that rates the energy efficiency of buildings. Based on a concept by the Forum’s Global Future Council on Space Technologies, the rating system is designed to reward responsible behavior by both government and private sectors.

According to ESA, there are over 22,000 pieces of man-made debris, totaling some 7,600 tonnes, orbiting the Earth. In the vastness of space that may amount to less than a rounding error, but these dormant satellites, old boosters, paint flecks, and various bits of shrapnel left over from satellite collisions are flying about at hypersonic speeds, so a particle the size of a grain of sand can cause as much damage as a .50 caliber bullet.

ESA Releases Space Debris Report

In order to address the issues posed by space debris on spaceflight activities UNCOPUOS has taken the initiative to create a set of internationally agreed guidelines for the long-term sustainability of outer space activities.

The content of the this document is written in response to those guidelines by raising awareness of space activities, and aims to:

‘ Provide a transparent overview of global space activities, ‘ Estimate the impact of these activities on the space environment, ‘ And quantify the effect of internationally endorsed mitigation measures aimed at sustainability of the environment.

Recognising sustainable behaviour

Solving the growing problem of space debris will require everyone who flies rockets and satellites to adhere to sustainable practices, which doesn’t always happen. Creating a Space Sustainability Rating - MIT MEDIA LAB ... Space Sustainability Rating will create an incentive for companies and governments operating satellites to take all the steps they can to reduce the creation of space debris,” Wood says. Now there will be a way to recognise those who do. We increasingly rely on satellites for every-day activities like navigation, weather forecasting and telecommunications, and any loss of these space-based services could have a serious effect on our modern economies.

Yet vital orbital pathways around Earth are becoming more congested with trash, such as abandoned satellites and rocket upper stages or debris fragments from old satellites that have exploded.
