Typically, yes. Most astrogeologists have a strong foundational education in geology, which they then apply to extraterrestrial materials and remote sensing data from space missions.
Primary employers include space agencies (like NASA, ESA), national geological surveys with planetary divisions, research universities, and occasionally museums or science communication organisations.
