This piece describes the challenges posed by the increasing proliferation of orbital space debris, as well as debris falling back to Earth. It describes how a ‘business as usual’ case going forward threatens to result in outer space becoming less accessible and navigable, thus compromising future space activities. It describes the existing legal and governance frameworks that has been developed at the international level to address issues around space debris, concluding that more needs to be done if we are to maintain space as a sustainable area for the benefit not only of current, but also future generations.
Space is Ubiquitous and Critical
Over the past six decades, space-related technology has revolutionised the world we live in. Beginning in the 1950s/1960s with an initial focus on Government-led military and scientific activities, space has also become a very significant commercial sector, estimated in 2020 to be valued at $US385 billion, and growing at a significant rate (even during the COVID-19 period), far exceeding the growth of the broader global economy. In Australia, the Australian Space Agency is working towards a goal of facilitating the growth of the Australian space economy to reach $A12 billion by 2030.
Our use of outer space has developed to the point where it now plays an essential role in everyday human activities across the globe. You and I ‘use’ space many times a day in many different ways without even thinking about it. Space is ubiquitous and virtually every country on the planet requires access to some form of space technology, and the data it produces, as essential elements of its critical infrastructure. Seen in this light, a (theoretical) ‘Day Without Space’ would have significant negative consequences for every country, every community, every human on Earth. Indeed, the functioning of society as we know it would, in many respects, cease.
