Rovers, Helicopters, and Ancient Martians: Why We Explore Mars

With three countries sending missions to Mars in 2021, including the first Mars helicopter, there is new interest in the red planet. What do we know, and what do we hope to learn, about this alien world next-door?  Fraknoi will discuss the discoveries that revealed ancient Mars as a world much like the Earth, with lakes, rivers, and possibly the stirrings of life. Although Mars today is very different, since the small planet lost much of its atmosphere, we nevertheless hope to find evidence of past life – perhaps implying a second genesis – on its sandy surface. Using beautiful color images from the latest space probes, Fraknoi will show us the beauty of Mars and how new probes are exploring it. No background in science is required.
