Sample interview questions: How do you approach studying the potential for life in the subsurface of icy moons with potential energy sources for life?
Sample answer:
-
Explore the Subsurface Environment:
-
Utilize geophysical techniques, such as radar or seismic surveys, to map the moon’s subsurface structure, including the presence of subsurface oceans, lakes, or aquifers.
- Investigate the moon’s geological history and resurfacing processes to better understand the formation and stability of subsurface environments.
-
Study the composition of the subsurface through analyses of surface materials, meteorites, and data from spacecraft missions.
-
Search for Signs of Life:
-
Analyze samples from the moon’s surface and subsurface for evidence of extant or extinct life, including fossilized remains, organic molecules, or biosignatures.
- Utilize remote sensing techniques to detect spectral signatures associated with biological processes or the presence of water.
-
Conduct experiments to simulate the conditions of the subsurface environment and assess the potential for life to survive and thrive under such conditions.
-
Investigate Energy Sources:
-
Examine the moon’s internal structure and composition to identify potential energy sources, such as tidal heating, radioactive decay, or geothermal activity.
- Study the moon’s surface features, such as volcanoes or geysers, for evidence of current or past geological activity that could provide energy for subsurface life.
-
Investigate the potential for hydrothermal vents or other chemical disequilibrium environment… Read full answer
