Environmental limits to the space sector's growth

Lois Miraux

Summary: This paper comprehensively analyzes the major environmental impacts of space activities and their potential growth, highlighting issues such as space debris and light pollution. The suggestion to establish thresholds within the planetary boundaries framework to support awareness-raising and policy-making is proposed. The importance of environmental limits resulting from factors like rocket emissions and reentry particles is discussed, emphasizing the need for ecodesign in the space sector.

Estimating the CO2 intensity of the space sector

Andrew Ross Wilson

Summary: Conflicting methodologies for estimating the CO2 intensity of the space sector are starting to emerge due to insufficient publicly available data, leading to significant variations that compromise the credibility of reported results.

The case for space environmentalism

Andy Lawrence et al.

Summary: This article summarizes the case for considering the orbital space surrounding the Earth as an additional ecosystem and emphasizes the urgency and importance of addressing environmental issues in this region. It suggests that we should pay attention to and regulate damage to the orbital space environment, similar to how we manage the oceans and the atmosphere, while considering the impact on astronomy, stargazing, and the sustainability of commercial, civic, and military activities in space.

Ecospheric life cycle impacts of annual global space activities

Andrew Ross Wilson et al.

Summary: This study presents the first approximation of ecospheric life cycle impacts from global space activities using a streamlined Life Cycle Sustainability Assessment (LCSA) method. A new space-specific life cycle database and design tool were used to compile the inventory and generate results for two scenarios. The study highlights the potential future importance of addressing adverse life cycle impacts in the design process of space technologies and products.

Environmental sustainability of future proposed space activities

Lois Miraux et al.

Summary: This study evaluates the potential environmental impacts of future space activities based on proposed plans. Results show that these activities could lead to unprecedented impacts on climate change and the number of satellites in orbit. The effects of rocket launches and re-entries on the atmosphere are also highlighted, as well as the potential depletion of the ozone layer due to rocket-based travel and Mars colonization. These findings emphasize the need to consider environmental factors in space project planning and design.
