More than 50 years of missions to Mars paint a clear picture of a cold, dry, desert planet. And at the same time, photographs, minerals, and other data tell scientists that Mars once had as much water as Earth, or even more. Why are the two planets so different today?

If someone offered you the chance to drop everything, fly to Hawaii, and spend four months trapped in a dome with seven strangers in the name of science, would you do it? For writer Kate Greene, the answer to that question was a resounding “yes.” Greene was one of eight people selected to crew the very first HI-SEAS Mars analogue mission in 2013.

If you were an ant living in an anthill in the Serengeti and you wanted to know whether an intelligent species lived on planet Earth, how could you tell? A particularly clever ant might pick up a radio signal and deduce that humanity exists, but how about subtler, indirect clues that, nevertheless, are a result of technological development?

Leland Melvin’s scientific career began during his childhood in Lynchburg, Virginia, when he created a fantastic explosion in his living room with an at-home chemistry set. Little did Leland or his family know at the time that he would become both a professional athlete and a NASA astronaut, flying two missions to the International Space Station.

The latest episode of Third Pod from the Sun features an interview with planetary scientist Fran Bagenal, who has had a fascinating career working on NASA missions from Voyager to Juno and New Horizons. Currently working at the University of Colorado Boulder, Bagenal provides an overarching view of the different planetary missions going back a few decades and describes how the research and findings have built upon the innovations and discoveries that came before.

On 24 December 1968, humans witnessed our home planet rise over the horizon of another world for the first time. The crew of Apollo 8 looked up from the Moon to see the blue and white swirls of Earth poised above the stark grey lunar surface—a single oasis in a big, dark universe.

It’s no exaggeration to say Lori Glaze’s impact on our understanding of the relationships between Earth and our nearest neighbors is volcanic. In fact, eruptions fascinated her since she was a pre-teen learning about the destructive volcano which buried the Roman city of Pompeii or carefully scraping ash from the Mount St. Helens eruption off the hood of the family car in Seattle in 1980.

Scientists have been testing whether life exists on Mars for over 40 years, ever since the Viking 1 lander touched down on the Red Planet. Researchers often perform experiments on Earth to better understand the context of data collected by Viking 1 and subsequent landers – data that gives scientists tantalizing clues about the habitability of the Martian surface.

We’re trying something new with Third Pod. In addition to your regularly scheduled programming, we’re going to showcase short stories from scientists in a new series we’re dubbing Sci & Tell. Like show & tell, but with science (and audio)!
