What are the responsibilities and job description for the Venus Surface-Atmosphere Experimental Studies 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:
Venus is a hot, dry planet with an inhospitable atmosphere and is Earth‘s nearest planetary neighbor, excluding the moon. Earth and Venus are about the same size and mass, yet that is where the similarities end. Even with the array of missions that were sent to Venus starting in the early 1960‘s, we know surprisingly little about its chemistry either on the surface or in the lower atmosphere. In order to combat this knowledge gap, modeling and lab experiments are used to investigate possible Venus surface-atmosphere reactions. Venus‘ surface temperature and pressure (740K and 95.6 bar) suggest that chemical weathering is likely.
The research in this lab is mostly experimental though theoretical modeling is also encouraged. The main focus is exploring possible surface-atmospheric reactions through the use of multiple high-temperature (maximum 1000 °C) room pressure furnaces and/or a unique small, dual high temperature/high pressure system aptly named vici (Venus In situ Chamber Investigations) that enables experiments at Venus surface conditions under a carbon dioxide atmosphere (nitrogen and/or sulfur dioxide can also be introduced). This pressure system is not limited to geochemistry experiments; it can also include component testing under high temperatures and pressures. Even though Venus is the primary focus for current research, this doesn‘t preclude the use of the chamber or furnaces for other planetary targets; for example experiments could be designed to target exoplanets and their potential conditions. Ultimately, these types of experiments will lead to a greater understanding of our Solar System and potential change over time.
