Podcast Episode 113: The Blue-Haze Limb of Mars


While the color of
Mars is red, some photos show
Blue on the limb. Why?

While I’ve already addressed the True Color of Mars (episode 74), one remaining – and unmentioned – twist is the blue haze limb that is sometimes visible as the upper atmosphere in color images taken from Earth orbit; this episode addresses those. And, it’s a completely different phenomenon than just a crappy understanding of image analysis. Real science ensues!!

Feedback makes up over half of this episode. I talk about Episodes 112 (why Russell Humphreys thinks that magnetic fields should decay to begin with and how he made his prediction), 109 (a follow-up interview of Marshall Masters from just a few days ago), and 111 (general feedback and criticisms of the Cydonia movie).

Finally, TAM is less than 2.5 weeks away, and I’d love to meet my adoring fans you folks who tolerate listening to me every now-and-then. Please let me know if you’re going AND interested in meeting up. Otherwise, I may have to spend all my time with a Hershey chocolate -lover, and we don’t want that now, do we?

And über-finally, I got a special e-mail while I was recording this episode. Listen to it all the way through to hear it. 🙂

Oh, and super-düper-finally, about the release schedule: Some of you may have noticed has been a bit off lately. The excuses are the usual, but ostensibly, the podcast is “supposed” to come out on the 1st, 11th, and 21st of the month. And that’s how I date them in the RSS feed. But, in the intro, I state that this is an episode for a certain third of the month, so that’s been the justification in my head for being able to get it out a little late. And looking at my upcoming schedule, I think that you can probably expect more of the same at least until September. They should be on or about the 1st, 11th, and 21st, but won’t necessarily be exactly on those dates.
