What we do

Earth-Space Sustainability is a research initiative founded in December 2020 aimed at using social science knowledge to tackle the dual-challenge of (1) outer space sustainability and (2) attaining the United Nations Sustainable Development Goals (SDGs) through new space based infrastructures. In so doing, Earth-Space sustainability calls for a paradigmatic shift towards the notion of a sustainable Earth-Space relationship.


The idea of outer space sustainability has often been perceived as 'distant' to immediate challenges on Earth, such as climate emergencies. In the New Space age, the outer space environment will increasingly influence sustainability on Earth in ways beyond what most of us have realized. We are now witnessing the dawn of an era in which the sustainability of Earth and Space environments become more intertwined than ever.


Social sciences have spent decades of research on tackling Earth's sustainability challenges. Extending what we have learned so far into the space realm will better prepare us for the new kinds of challenges outer space might bring. An integrative perspective of Earth-Space Sustainability could in turn inform us on new ways of managing the vulnerable planet we live on.

Earth-Space Sustainability aims to use evidence-based social science research to inform forward-looking policy scenarios. Informed by research on sustainability transitions, innovation systems, development economics, socio-ecological and Earth System governance, we use in-depth qualitative and quantitative methodologies to analyze complex Earth-Space sustainability challenges. Our research deals with upcoming challenges in the following three domains:


Developing an Earth-Space paradigm


What is beyond Anthropocentrism?

Extending planetary boundaries to outer space


Shaping a sustainable relationship


Peaceful use of outer space

Inclusive Earth-Space economy


Deploying space technologies to attain SDGs



Contributing to an emerging Earth-Space governance framework

Integrating social science research


Deriving strategic actionable policy insights


Research on Earth-Space Sustainability

Earth-Space Sustainability currently focuses on the following areas concerning Earth-Space sustainability: peaceful use of outer space, inclusive and sustainable Earth-Space economy, and the attainment of SDGs through space based infrastructures. With that, Earth-Space Sustainability asks the following questions and seeks informed answers to help tackle these emerging challenges:

Peaceful use of outer space

How are space security challenges affecting sustainable development?

How can we move towards space disarmament?


What are the most critical challenges when it comes to space traffic management and clearing space debris?


Key Areas

Understanding the satellite value chain

The satellite sector is booming and even more so in the coming decade. To ensure an
inclusive and sustainable use of space, we ask questions like Who own those satellites? Who built those satellites? Who launched the satellites into Earth’s orbit? Which orbit? Who have access to the satellite data?
