Mars-style

We’ve arrived at our destination pretty much safe and sound — thanks to all of you who wrote to wish us well.  I was going through all the news that’s piled up while we were on the road, and noticed a story about “warm” weather on Mars and how some landforms show evidence of freeze-and-thaw cycles that indicate warmer weather sometime in the past. Very interesting and a great object lesson in what you can learn by studying landforms.

Driving across the landform that is the Great Plains of the United States, I couldn’t help but think about how millions of years ago the whole area was under an ocean. The landform is gentle and and rounded, with a few hills here and there. Of course, we went through some of our own “warm” weather the past few days — sweltering temps and some pretty severe storms. Those are short-term compared to the long-term existence of things like oceans in the past or the yearly freeze-thaw cycle on Mars that spurred the recent finding.  But, it’s all planetary science — and it’s all still in the landforms, if you know how and where to look!

I’m currently driving cross-country to a new home.  It’ s a huge move; all of our stuff is on a moving van, we have us and the cats in our cars.  The scenery this time of year is gorgeously green — at least along I-80. But, what has kept my attention both nights has been the sight of a lovely crescent Moon high in the west. One of the pleasures of skywatching is to see such sights and then let the imagination wander about how cool it is that we have another world so close that we can see its curvature without needing binoculars or a telescope. If we lived on a planet without a Moon, I often wonder how long it would have taken humans to intellectually figure out that other worlds exist, and what their characteristics are?

If you get a chance, get outside and check out the Moon the next few nights. It’s lovely!!
