What are the responsibilities and job description for the Geophysical Investigations of Habitability in Icy Ocean Worlds position at Zintellect?
About the NASA Postdoctoral Program
The NASA Postdoctoral Program (NPP) offers unique research opportunities to highly-talented scientists to engage in ongoing NASA research projects at a NASA Center, NASA Headquarters, or at a NASA-affiliated research institute. These one- to three-year fellowships are competitive and are designed to advance NASA’s missions in space science, Earth science, aeronautics, space operations, exploration systems, and astrobiology.
Description:
Geophysical measurements can reveal the structures and thermal states of icy ocean worlds (Vance et al. 2018, Styczinski et al. 2021). The interior density, temperature, sound speed, and electrical conductivity thus characterize their habitability (Vance et al. 2016, Vance et al. 2021, Vance et al. 2024). 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.
We seek diverse expertise relevant to these topics. There is significant work happening in the realm of applied theoretical and experimental aqueous chemistry where a new project would be welcomed. There is also a current need for an individual with a strong background in solid earthgeophysics or geochemistry, and in programming in python and matlab. The preferred candidate would demonstrate a commitment to open source (FAIR) practices and knowledge of tools such as github and sphinx.
