Where In The Universe #127

It’s time once again for another Where In The Universe Challenge. Name where in the Universe this image was taken and give yourself extra points if you can name the telescope or spacecraft responsible for the image. Post your guesses in the comments section, and check back on later at this same post to find the answer. To make this challenge fun for everyone, please don’t include links or extensive explanations with your answer. Good luck!

UPDATE: The answer has now been posted below:

This is Mars, as seen by the HiRISE camera on the Mars Reconnaissance Orbiter. It is sandfalls in the north polar region of the planet. This image was part of the new PDS release this week. You can see a color version and get more info on this image at this link on the HiRISE website.

And you can now find the answer to last week’s WITU challenge (which was of the image below) back at the original post (sorry for the delay in posting the answer!)

  1. I am going to have to go with my gut and say dark barchan sand dunes on Mars, but maybe by Mars Odyssey?

  9. It´s not Brazil, as the dunes there are white. It´s not Japetus, as there is no atmosphere on Japetus and thus no wind to build up dunes and blow them along the icy surface.
    I think it is somewhere on Mars close to its north pole. There are volcanoes in the area the ashes of which were blown into dunes by the cold winds falling from the icy pole cap. The picture may be taken by the Mars Reconnaissance Orbiter.

  14. Chasma Boreale (northern ice cap) Mars, ice and substratum, Mars Global Surveyor, Mars Orbital Camera image, probably from February 2005.
