The challenge aims to advance in-situ resource utilization (ISRU) technologies, enabling the extraction and use of resources directly from the lunar surface. These technologies are crucial to reduce reliance on Earth-supplied resources and foster sustainability in space exploration. Lunar regolith, the Moon's surface soil, can be processed to extract oxygen and metals such as silicon, iron, and aluminum, which could be used for construction.
Additionally, water ice found in shadowed craters can be converted into drinking water, breathable oxygen, and hydrogen fuel for rockets. Such developments could also pave the way for more sustainable mining and manufacturing on Earth.
"Competitions like the Space Resources Challenge incentivise creativity and innovation, providing opportunities for smaller players to contribute to solving some of the most critical problems in space exploration. ESA's unifying role in such initiatives fosters cross-border partnerships within Europe between SMEs, research institutions, and industry leaders and ensures Europe's competitiveness in the global space sector," said Daniel Neuenschwander, ESA's Director of Human and Robotic Exploration.
The inaugural Space Resources Challenge saw thirteen teams compete in developing technologies to locate and prospect lunar resources. Five of these teams advanced to a final test in Luxembourg, with the winning group securing a euro 500,000 development contract with ESA.
The current challenge focuses on the collection and processing of lunar regolith. Participants will design and operate robotic systems capable of sorting lunar soil and extracting sufficient oxygen for future Moon missions. This challenge will take place at LUNA, a new lunar simulation facility at the European Astronaut Centre in Cologne, Germany. Proposals are being accepted until February 20, 2025, after which the selected teams will conduct their field test in October.
ESA plans to continue launching a Space Resources Challenge every three years to stimulate ongoing innovation, supporting the agency's mission to ensure Europe plays a key role in the sustained exploration of the Moon and beyond.
