Samantha (Sammie) Jacob is a PhD student with Jim Bell at Arizona State University studying the mineralogy of Mars using multispectral data. Growing up with the Rocky Mountains as my backyard, I grew up dreaming of traveling among the stars and collecting rocks from my driveway. I moved from the mountains to the middle of the Pacific Ocean to get my B.S. and M.S. in Geology and Geophysics from the University of Hawaii at Manoa. It was during my masters in 2012 that I started working with data from Mars rovers, working first with data from the MSL Curiosity rover. I am still in charge of calibrating data from the Curiosity Mastcam instrument, and now I’m assisting the Mastcam-Z team at ASU to prepare the calibration procedures for the Mars 2020 Perseverance rover.
