Earth Science Week 2012 began yesterday and runs all week. The theme this year is "Discovering Careers in the Earth Sciences." There are lots of different careers to be had that center on geoscienceyou don't have to work as an oil-rig roughneck, become a grizzled prospector or even grow a beard. You can do cool lab work with big steel machines, advise investors, practice law, be a forensic detective, clean fossils, be a writer or any number of other things. The space agency NASA is a big participant in this year's Earth Science Week, and for career ideas you'll do well to visit its special careers page.
