On the Subsurface Exploration of Ocean Worlds in the Outer Solar System with the TRIPLE project — •Mia Giang Do1, Jan Audehm1, Dirk Heinen1, Johanna Hermannsgabner1, Sharif El Mentawi1, Andreas Nöll1, Shreyans Sakhare1, Christopher Wiebusch1, Yuting Ye1, Simon Zierke1, Clemens Espe2, Marco Feldmann2, and Gero Francke2 for the TRIPLE-nanoAUV collaboration — 1RWTH Aachen University - Physics Institute III B, Aachen, Germany — 2GSI - Gesellschaft für Systementwicklung und Instrumentierung mbH, Aachen, Germany
In search of extraterrestrial life, the icy moons in the solar system are prime targets as they are suspected to harbor a subsurface ocean of liquid water. Future space missions to explore these subsurface ocean worlds are of great interest. A mission scenario includes landing on the surface, penetrating through the massive ice shell with a probe, and diving into the ocean with an underwater vehicle that is collecting samples for identifying potential habitats. Within TRIPLE (Technologies for Rapid Ice Penetration and subglacial Lake Exploration), a system containing three components: a melting probe, a miniaturized autonomous underwater vehicle and an in-situ astrobiological laboratory, is in development. Aiming for a mission to Jupiter's moon Europa, the system will be tested in an analogue environment in Antarctica. The talk will give an overview of the TRIPLE project with a focus on the technological challenges of the melting probe and the latest status of the system. TRIPLE is a project line that has been initiated by the German Space Agency at DLR.
