For over 40 years, Andrea Mosie, a NASA "Hidden Figure" has dedicated her career to Apollo moon rock samples. Mosie works in a clean lab at Johnson Space Center working with the samples to help allocate them to different scientists around the world who need them for research. This includes making sure a ton of different steps and procedures are precisely followed so that no samples are lost, contaminated, damaged, etc. The story of how she ended up there and why she loves her work is one of dedication and love for her craft.
