VERITAS Mission Leadership

Dr. Sue Smrekar, VERITAS Principal Investigator

Dr. Smrekar (she/her) is a senior research scientist at NASA’s Jet Propulsion Laboratory (JPL) in Southern California. She is an internationally recognized expert on the surface and interior of Venus.

Her work focuses on understanding the key factors that cause terrestrial planets, especially Venus and Earth, to evolve along different paths. Dr. Smrekar’s research integrates geophysical modeling, data analysis, and geologic constraints.

Dr. Smrekar has assembled a diverse science team of leading experts from around the world for the VERITAS mission.

Dr. Darby Dyar, VERITAS Deputy Principal Investigator

Dr. Dyar is the Kennedy-Schelkunoff Professor and Chair in the Department of Astronomy at Mount Holyoke College in South Hadley, Massachusetts. She also is a Senior Scientist at the Planetary Science Institute in Tucson, Arizona.

In addition to being the deputy principal investigator for the VERITAS mission, Dr. Dyar is the co-lead for the mission’s Venus Emissivity Mapper (VEM) instrument.

Darby Dyar wears an orange blazer, dark slacks, and a multi-colored scarf as she stands on a stage with decorative panels behind her that have circles of various sizes. The backs of heads of some spectators in the audience also can be seen.
