My other is geological sciences too. I am a geology major, astronomy minor, planning on getting a masters and PhD in planetary geology.
I am planning to study extrasolar planetary geology and be a part of the future classification, mapping, and habitability of Earth like terrestrial planetary systems and using analogues like Mars, Venus, Eruopa, Enceladus and Titan to improve our understanding of the possible abodes for life in the universe, as well as future colonization potential in our solar system and beyond.
