Laboratory of Extraterrestrial Ocean Systems (LEOS)
About us:
Extraterrestrial oceans refer to bodies of liquid water located beyond Earth, often found beneath the icy surfaces of moons like Europa, Enceladus, and Titan. These oceans are significant in the context of scientific research and exploration, particularly as they align with China's strategic goals in deep-sea and deep-space exploration. This interdisciplinary field merges scientific inquiry with engineering advancements, focusing on the potential for life beyond Earth. In December 2017, the Extraterrestrial Ocean Systems Research Laboratory was established to study these oceans and their host moons. The laboratory's research, led by the LEOS group, addresses critical questions regarding the origin and limits of life in the universe. Their key focus areas include:
This research is crucial for understanding not only the potential for life beyond Earth but also the broader implications for planetary habitability and the evolution of life in diverse environments.
Research Objectives:
The Extraterrestrial Ocean Systems Research Laboratory employs a multifaceted approach to enhance our understanding of extraterrestrial oceans on icy moons. The laboratory focuses on investigating fundamental issues, such as the mechanisms of formation and evolution of solar system water bodies, as well as the dynamic processes of matter and energy exchange between these ocean systems and their external environments. Key strategies utilized by the laboratory include leveraging diverse research methods like laboratory and numerical simulations to replicate extraterrestrial ocean conditions and analyzing data from Earth's extreme environments as analogs. The laboratory also aims to establish an integrated "Extraterrestrial Ocean Extreme Environment Simulation System" for comprehensive studies of these enigmatic water bodies.
Furthermore, the research involves studying the interactions between seawater and the rock sphere in Earth's deep-sea and polar regions, as well as examining how cold-loving organisms adapt to such extreme conditions. This comparative analysis provides valuable insights into the potential habitability of extraterrestrial oceans. In addition, the laboratory conducts preliminary work on deploying and testing extraterrestrial ocean exploration equipment, laying the groundwork for future advancements in technologies necessary for exploring these distant worlds. By integrating these strategies, LEOS seeks to advance knowledge about the formation, evolution, and potential habitability of extraterrestrial oceans beyond Earth.
