Sampling Enceladus’ Subsurface Ocean with TIGRE Mission Concept
- A recent study at the AGU 2024 Fall Meeting introduced the TIGRE mission concept aiming to explore Enceladus' surface and subsurface ocean to potentially discover life.
- The TIGRE mission concept comprises an orbiter, lander, and drill to delve into Enceladus and lay the groundwork for future icy moon exploration.
- Motivated by NASA's SEES program, the team designed TIGRE to align with current NASA work and the Decadal Survey's priorities focusing on celestial bodies with signs of life potential.
- TIGRE aims to enhance Cassini mission findings by closely examining Enceladus' secrets, drilling to the subsurface ocean for water samples and assessing habitable zones.
- Specifically, TIGRE targets Enceladus' Tiger Stripes for potential landing sites to collect ocean samples, emphasizing flat terrain and proximity to geysers for mission success.
- Beyond Enceladus, TIGRE's mission objectives include advancing technologies for future exploration of other icy moons within the solar system.
- The mission's design involving an orbiter, lander, and drill could set a precedent for exploring icy surfaces on Earth and other moons with potential habitable environments.
- Progressing from concept to reality requires learnings from missions like Europa Clipper, advocating for life discovery to enhance NASA's budget, and rigorous testing of TIGRE components.
- Enceladus' subsurface ocean indicates the potential for life due to its key elements and hydrothermal activity, resembling conditions for life as known on Earth.
- While TIGRE may provide insights into Enceladus' potential for life, uncertainties remain due to various factors, such as thin atmosphere and undetected chemicals.
