Understanding Other Solar Systems

Possible Boulder/San Antonio Synergies Detection of magnetospheres and implications for the state of planetary cores. Study of the heliosphere and the long-term stability of sun-like stars.

How Does Life Begin and Develop? Goal 1: Understand how life arose on the Earth. Goal 2: Determine the general principles governing the organization of matter into living systems. Goal 3: Explore how life evolves on the molecular, organism, and ecosystem levels. Goal 4: Determine how the terrestrial biosphere has co-evolved with the Earth.
