Ep. 432: Geoglogic Ages of Mars – From Wet and Wild to Desolate Desert
Today, Mars is a desolate wasteland, with dusty red rocks and sand stretching out to the horizon. But billions of years ago, it was a vastly different world. It was blue, with oceans, rivers, lakes, and maybe life? Let’s tell the story of geology on Mars, and we got from that world to the one we see today.
Ep. 431: The Search for Life on Mars
Enceladus and Europa are all the rage these days, but classic Mars is still a great place to search for life. In fact, ESA’s ExoMars is scanning the planet’s atmosphere for methane, evidence that there might be life there right now. Let’s talk about the search for life on the Red Planet.
Ep. 430: Coming Home from Mars, Part 2
Join us as we try to finish the interrupted episode Coming Home from Mars!
Landing on the surface of Mars is very difficult. In fact, it’s probably the toughest planet to land on in the whole Solar System. Today we’ll talk about what it’s going to take to get to and return from Mars!
No Astronomy Cast this week Nov 28- Dec 2
Hey folks, just letting you know that due to Fraser being at conference this week, we won’t be recording an Astronomy Cast any time. Unfortunately, our last show was interrupted by a power outage, and we’ll try to get back together to finish that one on Monday, 12/5. We will keep you posted as info updates!
Ep. 430: Coming Home from Mars
Landing on the surface of Mars is very difficult. In fact, it’s probably the toughest planet to land on in the whole Solar System. Today we’ll talk about what it’s going to take to get to and return from Mars! [Note – This episode was interrupted due to a power outage on Fraser’s end. They’ll reschedule to finish episode on 12/5 (most likely – Fraser is traveling this week!), and we’ll put the pieces together when we have them and release as audio podcast!]
Ep. 429: Living on Mars
When Elon Musk announced plans to send humans to Mars, he conveniently left out one important aspect. How are we supposed to survive on a place this hostile to life? Seriously, Mars sucks, and it’s going to take some impressive techniques and technologies to make it on the Red Planet.
Ep. 428: The Moons of Mars
We begin a miniseries on Mars. How many episodes will we do? Who knows? But we start today with a discussion of the two Mars moons, Phobos and Deimos.
Ep. 427: Click Bait vs Clear Science
Did you hear that Dark Energy doesn’t exist any more? Neither does Dark Matter? It turns out that NASA recalculated the Zodiac and now you’re an Ophiuchan! Science is hard enough, but communicating that science out to the public when there are publications hungry for traffic is even harder! Here’s how to parse the click-bait science titles.
Ep. 426: Confirmation Bias
I hate to tell you this, but that meat computer in your skull is constantly betraying you. Don’t worry, we’ve all got the same, but fortunately, scientists have learned how this happens, and can help us make sure our science, and lives don’t suffer because of it.
Ep. 425: Naming Spacecraft
Have you ever noticed spacecraft missions have some pretty cool names? How does anyone decide what to call these things?
