Awesome Pictures of Sand Dunes on Mars from HiRISE!
73
The sand shown in the picture appears to have come from the layered mesas and knobs, features that have been eroded by powerful winds in Mars. The pictures from the Mars show two types of dune structures known as barchan and seif dunes.
The above picture is a barchan dune and in the below picture you can see both barchan and seif dune.A barchan dune is an arc-shaped sand ridge, comprising well-sorted sand. This type of dune possesses two "horns" that face downwind, with the slip face (the downwind slope) at the angle of repose, or approximately 32 degrees. The upwind side is packed by the wind, and stands at about 15 degrees.
Seif dunes are longitudinal dunes that elongate parallel to the prevailing wind and thought to develop from barchans if a change of wind direction occurs.
Here is another picture of seif dunes in Mars:The dunes structure indicates the wind is blowing from west to east in Mars according to the NASA Scientists.
These are just the first images from the region, we can expect more pictures very soon.You can see more pictures from this HiRISE experiment here.

Jonixk, I also think the same, whatever we can imagine it is possible to create. Some of the Star Trek technologies are slowly coming up, so it will be interesting in the future.
Run for cover there not sand dunes at all they're...they're giant hoof prints ........
Great Hub CGull regards Zsuzsy
You are right Zsuszy, they do look like hoof prints, who knows there might be giant horses there :)
Pretty strange looking dunes, will be interesting to see the images that follow.
It more looks like Earth, hope we are able to make it habitable to live.
nice art work on Mars good hub
Commentonthis. Yes it is neat like art work.
It would be really helpful if you could post links to the originals of all your photographs. I see the link to the first one, but the other two? I dont know about other people, but I like to go and examine the originals where there are cut-down versions on hubs. Thanks.
These ones you have posted about really do look like sand dunes as opposed to these... (http://hubpages.com/hub/Mars-A-Herd-of-Quietly-Gra which look strange, but probably are still just another example of sand dunes!
Umkeyra, they all are available in Nasa.gov. Thanks.
The movie is a representation true veiled representation of the martians who were formerly from the Lyraen home world. THeir neigboring cousins the Maldekians who planet latter perished. Their other brethern were separatist known as Atlantians who clashed quite violently with a Reptilians Species as opposed to the mammalian species of Humanoid the Martians, Maldekians and Atlantian.
The Fake Space program is lieing to you. The Martians built vantastic cities but on the surface and in the planet it self latter on. The interesting part is that they had no economic system which is a slave system. They were naturaul farmer who used genectically engineered giant sand worms to irrigate the martian soil for farming. The martians were also highly dependent on mother goddess oracle ring a bell in dune movie who is the peoples sole healer, oracle and councelor of all of the martian people. The Bene Gesserit Reverend Mother are a key social, religious and political force in Frank Herbert's science fiction Dune universe. The sand worms continue to this very day roaming the surface. And their are momuments all over mars such the face on mars.
TPTB like to tell you indirectly half truths.
Truth is even stranger then fiction.
Myth and Fairy tales are more likely true then they are false.
Thanks Sov31415 for your perspective.

Beautiful images this ones. It makes me remember th movie DUNE. This make me think, that all science fiction movies could have a hidden truth!
