•Knowledge on chemical reactions has implications for the past and current state of Venus
- Venus may have had liquid water on its surface [5], thus hydrous silicates may have formed at that time [6].
- The Venus Emissivity Mapper (on VERITAS and EnVision) will be used to determine bulk composition of the surface by observing transition metal content [8-9]
- Calcium diffuses through basalt to react with CO2 and SO2, changing the bulk composition and decreasing the emissivity from orbit [8]
- Experiments investigating kinetics will be informative for future emissivity data
•Goal:
- Constrain reaction rate between several calcium minerals and SO2
- Determine the effect, if any, crystal lattices may have on these rates
