A Piece of Mars: Just like at Earth's Grand Canyon, erosion on Mars has created some really beautiful landscapes. This 480×270 m (0.3×0.17 mi) scene shows rugged terrain that was once buried in sediment. Does the texture here represent the landscape before it was buried, or was it created in the ...

A Piece of Mars: Click on this 0.96×0.54 km (0.6×0.33 mi) scene to see it in detail. Many thin, narrow landslides have formed on these dust-coated hills. As far as I'm aware, there's nothing like this on Earth. Inside the landslide scars, there are small dusty ripples about 1.75 m (~6 ft) in ...

A Piece of Mars: The two small dark craters (2.25-2.4 m, or 7.4-7.8 ft across) are brand new, having appeared in CTX images sometime between May 2007 and April 2008. They punched through a layer of bright dust and threw up some darker material, which the wind carried downwind (near-surface winds ...

A Piece of Mars: Some parts of Mars, like this one, are very dusty. This 1.92×1.1 km (1.2×0.67 mi) area has built up a thick deposit of dust that slowly buries the impact craters until they're mere ghosts of the deep bowls they once were. If you knew the dust fallout rate, you could date the age ...

A Piece of Mars: There's a dune field migrating past a 230 m (755 ft) diameter crater, creating a 1.6 km (1 mi) long “shadow” that's empty of dunes. Why? The rim of the crater pokes up just enough to affect the wind, like pebbles in a stream. Either the sand is diverted around the crater, ...

A Piece of Mars: This 90 m (295 ft) crater impacted into a windy, cratered plain. It's now partly filled with dark sand, but where did that sand come from? Looking closely you'll see that many of the boulders that were flung out during the impact have little “tails”. These tails show that wind ...

A Piece of Mars: This 0.98×0.54 km (0.61×0.34 mi) scene shows ancient windblown bedforms (maybe dunes) that have been partially eroded by the wind. The wind has left behind ghostly stripes: these are remnants of where these things once were, back when they were still actively migrating.

A Piece of Mars: Three things are trying to hide in this 0.96×0.48 km (0.6×0.3 mi) scene. 1) Craters are slowly being both scoured and buried by migrating sand, 2) the sand itself is hiding in the lee of crater rims and other topographic obstructions to the wind, and 3) small patches of ice ...

A Piece of Mars: Not all dunes on Mars are moving at a measurable pace. This 0.96×0.45 km (0.6×0.28 mi) scene looks a lot like one I posted 3 years ago called Martian Sports. This image shows the same dunes 9.5 years apart (that's 5 Mars Years). There are a few places where patches of sand have ...

A Piece of Mars: This 0.96×0.54 km (0.60×0.34 mi) scene shows two sets of bedforms (dunes), each aligned in different directions. The more closely-spaced set has sharper crests, and it's superposed on top of (and it is therefore younger than) the more widely-spaced set.

SETI is advertising my review article. Cool.
By Lori Fenton - Senior Research Scientist. When was the last time you dusted your house? Did you hate it as much as I did? As readers living in more arid climates already know, a significant fraction of the dust that accumulates in your home, and everywhere else on Earth, is composed of tiny ...

A Piece of Mars: This 480×270 m (0.3×0.17 mi) scene shows a herd of 100-300 m fine-toothed combs grazing on the surface of Mars. Wait, what? No, it's not really combs. This is actually a landscape covered by two sets of windblown bedforms. The larger ones (the “comb” shafts) are very old, ...

Hmm, not a bad thought.

I've taken my cats here for years and found them to be helpful, caring, and honest. It's a small business, so sometimes there's a wait before getting in. But it's worth it.
