Exo-Ocean Exploration with Deep-Sea Sensor and Platform Technologies

Area of Science:

• Astrobiology
• Planetary Science
• Oceanography

Background:

• Enceladus, a moon of Saturn, harbors a subsurface ocean, making it a prime target for extraterrestrial life detection.
• The search for life in icy moons' oceans is a growing area of astrobiological research.

Purpose of the Study:

• To propose a bio-exploration concept for Enceladus' exo-ocean.
• To adapt terrestrial deep-sea exploration technologies for extraterrestrial applications.
• To consider a wide range of potential life forms, from microbial to animal-like.

Main Methods:

• Focus on combined direct and indirect life-detection capabilities.
• Utilize optoacoustic imaging, passive acoustics, and molecular approaches.
• Integrate geochemical and oceanographic measurements.

Main Results:

• The proposed concept leverages state-of-the-art sensor and robotic technologies.
• It includes multidisciplinary monitoring adaptable from terrestrial deep-sea observatories.
• The design incorporates cabled observatories and mobile platforms like AUVs and ROVs.

Conclusions:

• The proposed concept offers a feasible approach for exploring Enceladus' exo-ocean for life.
• Adapting terrestrial deep-sea technologies is crucial for future astrobiological missions.
• A multidisciplinary approach is essential for comprehensive exo-ocean understanding.
