Monica Martinez paged through a book detailing the mineralogy of the moon last year, her confusion growing as she flipped back and forth through the sulfides section.
The only one listed as present on the moon was iron sulfide, a semiconductor that is found in lithium-ion batteries.
But that couldn’t be right.
Just a few days ago, she had found calcium sulfide — a compound often used as a base for luminescent materials — in a sample of lunar dust collected during Apollo 17, the last human mission to the moon in December 1972.
Did she just find a new compound on the moon? Maybe the book wasn’t up to date, thought Martinez, then a junior at the University of Houston studying mechanical engineering.
She did more research. The presence of calcium sulfide had never been documented.
