Speakers: Steve Murray

Topic: Novel Neighbors – searching for life on planetary moons    

SDAA Speaker

Two factors have generated new excitement among scientists searching for extraterrestrial life – better knowledge of where life can exist on Earth, and new insights into the properties of several planetary moons (like Europa, Titan, and Enceladus). The possibility of finding extraterrestrial life here in the solar system has motivated several new projects like the Europa Clipper and JUICE (Jupiter Icy moons Explorer) to gather definitive data to resolve the issue. Whatever the result, the understanding of “life as we know it” will be changed significantly among astrobiologists.

Steve Murray has been a space enthusiast since the Apollo era. Following a career in naval aviation, he completed an engineering PhD and went on to a research career in government.  He has been a visiting professor at the University of San Diego and is currently a freelance science writer and blogger. Most recently, he became a NASA Solar System Ambassador.
