Description:
Icy worlds are intriguing targets in the search for evidence of life beyond our own planet, as reflected in recent planetary science decadal surveys consistently placing a priority on missions to these bodies. A robust understanding of how icy materials behave under planetary conditions is essential for informing models and planning observations to optimize the science return of missions. The focus of our research group is on putative materials that are of relevance to ocean worlds (e.g. clathrate hydrates, organic co-crystals, and frozen brines), whose many fundamental properties remain largely unconstrained to date. Selected NPP fellows will help conduct research regarding the crystal structures, phase transition/behavior, heat capacity, thermal stability and reaction of these materials using a complementary suite of in-house analytical techniques, including spectroscopies (infrared, Raman, UV), powder X-ray diffraction, optical microscopy, and differential scanning calorimetry. These projects are directly relevant to NASA’s Science Strategy Plan as they support the agency’s exploration initiatives and focus on scientific discovery.
Interested candidates with significant laboratory experience and familiarity with the experimental techniques are encouraged to apply, especially those with expertise in crystallography and structure solution.
