Space exploration has always been a source of wonder and inspiration, pushing the boundaries of human knowledge and achievement. However, as we expand our presence in the cosmos, it’s crucial that we also consider the impact of our space activities on Earth’s atmosphere. The European Space Agency (ESA) is excited to announce an upcoming workshop, titled “Understanding the Atmospheric Effects of Spacecraft Re-entry.” 

Workshop Overview

The “Understanding the Atmospheric Effects of Spacecraft Re-entry” workshop is a collaborative effort aimed at addressing the complex challenges posed by spacecraft re-entry into Earth’s atmosphere. It brings together experts from diverse fields, including atmospheric chemists, physicists, material experts, representatives from the space industry, and international space research organizations. The primary goal of this workshop  is toidentify knowledge Gaps in our understanding of re-entry modeling.

Environmental Impact

Space-related activities have far-reaching consequences for our planet. These activities can contribute to climate change, ozone depletion, resource depletion, toxicity, and biodiversity loss. As part of the workshop’s objectives, we will discuss the need for a complete environmental life cycle assessment and eco-design approach to space products and services. This approach seeks to minimize the environmental impact of space-related endeavors throughout their entire life cycle.

Recent measurements have shown that approximately 10% of stratospheric aerosol particles contain aluminum and other metals originating from satellite re-entry. With a projected global increase in satellite launches and re-entry events in the coming decades, it’s imperative that we understand the potential influence of sustained metallic content on stratospheric aerosols and the atmosphere as a whole.
