Suzanne E. Smrekar

Suzanne E. Smrekar is an American geophysicist and Deputy Principal Investigator for the Mars InSight lander and the principal investigator for the planned VERITAS space probe to Venus.

Background

Smrekar obtained her B.S. degree in geophysics and mathematics from Brown University in 1984, and her doctorate in geophysics from Southern Methodist University in 1990. She was a postdoctoral researcher at MIT before joining the Jet Propulsion Laboratory (JPL) in 1992.

Career Published works

Smrekar and colleague Ellen Stofan reported in Science in 1997 that Venus' heat loss was caused by volcanic activity and formations specific to Venus. As Venus has no plate tectonics like Earth, she and others are attempting to study its volcanalogy to draw better conclusions about the formation of Earth. Smrekar and an international team of researchers presented the Venus Emissivity Mapper (VEM) at a conference in 2018; this device scans the planet's surface at specific wavelengths to record the mineral composition, and uses other channels to determine cloud cover, weather, interference, and volcanic activity.

Smrekar remains a team member of the joint Brown – MIT NASA Lunar Science Institute. She has jointly written several articles for the Encyclopedia of the Solar System. She was Deputy Project Leader for the Mars Reconnaissance Orbiter (MRO), which, in addition to monitoring the eventual descent for multiple Martian instrument landings, used its shallow- and deep-penetration radar to uncover a pool of solid carbon dioxide at Mars' South Pole – "equivalent to Lake Superior." Direct observation of the Martian lithosphere led to some of the first accurate measurements of the interior temperature of the planet. Her Magellan probe uncovered newly-active geology on the planet. She designed the HP3 and GEMS instrument packages for the InSight mission, which commenced in 2016. Smrekar served as Deputy Principal Investigator in addition to constructing much of the ground-penetrant instrumentation for InSight. She lightly referred to needing to obtain sub-surface results of Martian geography and geology as understanding "...the whole enchilada" of non-Earth planets.

Minor planet discoverer

On 14 June 1983, Smrekar discovered asteroid 6819 McGarvey at Palomar Observatory. She named it after her mother, Flora McGarvey Smrekar (1924–1977). 2016 – Winner, NASA small robotics funding for VERITAS 2015 – Elected to International Academy of Astronautics 2012 – Keck Institute for Space Studies (KISS) lecture 1996 – Presidential Early Career Award for Scientists and Engineers, nominee 1993 – NASA Group Science Award, Magellan Science Group 1984 – Department of Geological Sciences Senior Thesis Award, Brown University
