Job description

Description

Geophysical measurements can reveal the structures and thermal states of icy ocean worlds (Vance et al. 2018). The interior density, temperature, sound speed, and electrical conductivity thus characterize their habitability (Vance et al. 2016). Recent modeling and laboratory measurements of physical properties enable more detailed views into the possible configurations of ocean worlds and predictions for future measurements. Further work is needed to predict the seismic, gravity structure, and magnetic properties of ocean worlds.

Forward modeling results relating geophysics to habitability are essential to NASA‘s objective of understanding the Earth, the Solar System, and the Universe, as they relate to the workings of planetary bodies and the nature of life. Such predictions are needed for planning observations and data synthesis for future missions such as Europa Clipper, which has the express goal of investigating Europa to understand its habitability. Such predictions are also important to the formulation of future missions, where defining testable objectives requires assessing whether key hypothesized features can be measured.
