Speaker: Steve Murray

Topic: NASA’s InSight Mission to Mars

SDAA Speaker

InSight is a robotic lander that will study the internal structure of Mars and the processes that shaped it. Launched from California on May 5, the probe will deploy three instruments to determine the seismic activity, interior heat flow and core composition of the Red Planet.  A blend of old and new technologies, InSight will touch down on November 28 and operate on Mars for two (Earth) years.

Because Mars holds the most accurate geologic record of all the inner solar system planets, InSight could provide clues to the evolution of all rocky worlds, including many exoplanets.

Steve Murray is a NASA Solar System Ambassador and freelance science writer. His past work life includes time spent in systems engineering, human factors, teaching and aviation.
