Talk abstract: 

Planetary science is the ultimate applied science. Through the application and integration of physics, chemistry, applied math, geology and biology, planetary scientists study the origin of organic and inorganic matter in the universe and how this matter condenses and aggregates in molecular clouds and disks to form planetesimals, planetary embryos and ultimately planets. Planetary science spans the experimental, theoretical and observational study of planets (including Earth and exoplanets), moons, and space debris like asteroids and comets, and the processes that form them. It focuses on objects ranging in size from micrometeoroids to gas giants, aiming to determine their composition, dynamics, formation, and history.
We are currently experiencing a golden age of planetary exploration and discovery. New exploration of planetary bodies in our solar system (especially the Moon, Mars, and Mercury and other minor bodies), combined with the rapid and increasing discovery of planets outside our solar system, are revolutionizing the science and our understanding of the place of Earth and humans within the cosmos.
In this brief talk, I will introduce the current research activities by my UC Davis colleagues in this exciting field, ranging from UV, infrared, and microwave spectroscopy aimed at understanding formation and destruction of complex astromolecules; using collisions as means to study planetary properties, and as a mode of planet formation; how do we uncover chemical and isotopic finger prints of planet formation processes and its timescale; and finally what we have learned from Mars Science Laboratory, NASA’s flagship mission to Mars.
