Satellite production processes encompass intricate procedures involving the utilization of scarce or rare elements, which significantly contribute to environmental impacts. The manufacturing of satellites involves the use of materials like aluminum or titanium alloys, with aluminum being the preferred choice due to its desirable properties. However, the extraction and processing of these raw materials come with environmental consequences such as deforestation, habitat destruction, and increased greenhouse gas emissions.

Moreover, the production of lithium batteries for satellites poses additional challenges. The manufacturing of these batteries is energy-intensive and often involves the extraction of lithium through environmentally damaging processes. This not only contributes to carbon emissions but also raises concerns about the social impacts on communities near lithium extraction sites.

Furthermore, the launch vehicles used to transport satellites into space require substantial amounts of raw materials, exceeding the material consumption of the satellites themselves. Booster stages of these launch vehicles are typically discarded into the ocean after use, resulting in the wastage of valuable materials and posing risks to marine ecosystems. Consequently, the satellite manufacturing process plays a crucial role in the overall environmental impact of satellite technology and highlights the need for sustainable practices in the aerospace industry.

Resource Consumption During Operations

The operational phase of satellite technology involves the management and utilization of resources across various components, including launch vehicles and ground installations. Although satellites, launch vehicles, and ground installations are not highly resource-demanding relative to overall raw material use, the manufacturing processes for satellites do rely on scarce or rare elements that have environmental impacts. Satellites are predominantly made of aluminum or titanium alloys, with aluminum being the preferred choice due to its lightweight properties. However, the manufacturing of these alloys and the collection of raw materials, such as lithium for batteries, can have negative environmental and social implications.

In comparison to satellites, launch vehicles require larger quantities of raw materials, further contributing to resource consumption during operations. The production of launch vehicles involves processes that consume significant amounts of raw materials, adding to the overall environmental impact of satellite operations. Therefore, while satellites themselves may not be as resource-intensive during their operational phase, the combined resource use of satellites, launch vehicles, and ground installations warrants careful consideration of their environmental impacts. Efforts to optimize resource consumption and reduce the environmental footprint of satellite operations are crucial in mitigating the overall impact on the environment.
