A prominent impact crater on Mars has been named in honor of LPL alumna, Dr. Nadine Barlow (1958–2020). For her dissertation at LPL, Nadine mapped and categorized every impact crater on Mars visible in Viking Orbiter imaging above a threshold size. In her subsequent career, she made many advances in our understanding of Mars from this dataset and from later enhancements. Nadine was a professor at Northern Arizona University, a noted leader in the field of Mars crater studies, and a dedicated teacher and mentor to students and colleagues. Nadine’s contributions to education and planetary science have also been recognized with a display at the Astronomy Discovery Center at Lowell Observatory (Flagstaff).
