Examine the chemical composition of the universe, the Sun, the planets, and their building blocks. Learn the origin of the elements and their evolution through Solar System history. Use isotopic data to trace cosmic genetic relationships and date important events like the birth of the first solids in the Solar System. Understand the chemical processes that segregate elements into different astrophysical and planetary reservoirs. Observe primitive and evolved meteoritic and planetary materials in the laboratory.
