Hi. I'm a postdoctoral scholar studying planetary geology in the Planetary Sciences Group at UCF.
I'm interested in diverse topics within planetary science, particularly surface mineralogy, comparative planetology and in-situ resource utilization (ISRU).
Currently working on:
High fidelity Mars and asteroid regolith simulants
In-situ resource utilization
Martian crustal alteration during magma ocean cooling
Deliquescence is the ability of certain materials to not only absorb moisture out of the atmosphere (i.e., hygroscopicity), but to actually dissolve in that water. Certain salts in the soils of Mars are likely to be deliquescent, and would quickly absorb water if brought into a humid, pressurized environment like a hab.
Here are two examples of deliquescent materials. The first is calcium perchlorate: Ca(ClO4)2. The video is sped up about 100x:
And here is iron sulfate: Fe2(SO4)3. This one is sped up ~900x, i.e., it deliquesces slower than the perchlorate:
It looks like the powders are melting, but in fact they are quite stable at room temperature in a dry environment.
