Problem Statement
The rapid growth of space exploration brings significant environmental challenges. Current rocket propulsion systems release immense quantities of CO2 and other harmful emissions during launches, exacerbating global climate change. Furthermore, the production and assembly of spacecraft consume extensive natural resources, often involving processes with high energy demand and material waste. As humanity ventures further into space, the long-term ecological impact extends beyond Earth, with potential implications for extraterrestrial environments as well. To ensure a balance between technological advancement and environmental stewardship, there is an urgent need for innovative solutions that reduce emissions, optimize resource efficiency, and promote sustainability in all phases of space missions—from manufacturing to launch operations and beyond.
