Cosmochemistry is the study of the chemical composition of the universe and how it came to be. The field originated in the 1930s, long before space missions started collecting samples of moon rocks and space dust. Helpfully, the universe regularly deposits extraterrestrial matter on Earth in the form of meteorites — and it's been doing so since time began. Cosmochemistry researchers don't have to leave their home planet to find plenty to study.
