This is the episode for all those with questions about what we know about Mars. Specifically, how Mars went from being potentially habitable to the desert we see today. Guest Bruce Jakosky, the Principal Investigator for NASA’s MAVEN Mars orbiter explains it all.

NASA’s MAVEN orbiter has arguably done more to document how and why Mars lost its atmosphere and much of its water than any spacecraft ever sent to the red planet. The mission’s principal investigator, planetary scientist Bruce Jakosky is this week’s featured guest and we discuss the current paradigm on why Mars went so horribly wrong. Jakosky offers a candid and inside look at how such missions work and what we can expect from Mars science in the next few years.
