Pale gold satin sand
Polygons of dunes

A piece of Mars: Sand sometimes piles up on steep slopes. It forms downslope streaks as it slides downhill, which here appear like long narrow stripes, like shimmering satin (down is toward the lower left). Note the wind-blown ripples in the lower left: here the wind has disturbed those long streamers, reshaping the surface into those ripples (probably by downslope winds).

Have you ever considered about including a little bit more than just your articles?
I mean, what you say is fundamental and everything. However imagine if you added some
great graphics or video clips to give your posts more, “pop”!
Your content is excellent but with pics and videos, this site could definitely be one of the very best in its niche.
Very good blog!
A good point. Unfortunately I’m not paid to make these blog posts, and I can’t spare any more time.
Pale Gold Satin Sand?Is that real gold?If So???Than we should mine it and make money from it and then travel back to Mars and explore the red Planet.Or use it to pay down the debt!!! That and explore other Planets in our Solar System.Instead of throwing our military might around the World. Regards,Dave 🙂
No.. it means what it says – ‘sand’.. pale gold is a colour description. When you say someone has pale golden skin you don’t mean their skin is actually made from the mineral gold.
No, it’s not real gold.
If you want gold, just figure out away to harness the gold created from a supernova. Oh, and also a practical method of getting there. Too bad it doesn’t exist yet.
Just finding gold won’t pay off the deficit. From your comment, you’ve never been in the military, nor really bothered to learn anything about it. Space exploration is expensive. Straight up. I’m cool with it, and wish we could do more, but it would be nice if we found a cheaper means of travel.
Correct, the sand pictured here is neither gold nor satin. I was using artistic license to describe what it looks like.
Great post Lori! Also see http://www.uahirise.org/PSP_010277_1650

Thanks! But I’ve recently lent out my red/blue glasses, which means they’re lost to history. I need to get some new ones!
