  ! On closer inspection it look like a #cloud or #sandstorm

  Beautiful image. A #sandstorm perhaps or a dried up lake bed? The yellow tint could indicate #sulphur

  The lighting looks wrong to me for a lake bed. The shadows in the craters indicate a light source from the upper left.

  This is a work of art ? What is going on in it ?

  I think the planet4 team can't easily track the location since it's a 'double blind test'. I've tweeted BBC team perhaps will find out 😃

  Its a shame there is no indication of scale in the images. The feature to the RHS could be the outline of an eroded or partly filled crater?

  after viewing in photoshop I'm convinces is a cloud/strorm 😃 You can see though it to the cratered terrain underneath and icasts a shadow

  stunning

  Large looking fan to the left, with a small storm, almost hindered by a sort of ridge, could be an interesting combination

  This is one of the most beautiful images of Mars I have ever seen. #FANandCRATER

  what is this pale blue gas-like shadow that is present in a lot of the images? especially near fans.

  One desert like, rough, pitted, then a high smooth area. left of pix different coloured areas. Green/brown surface, small volcanos?.

  My only concern with it being an icy tornado is there is a similar feature at the very top centre. If it is, then there seem to be 2 !

  I think the sunlight is heating the edge of the ridge causing gas to flow across the image, from bottom right to top left, obscuring it.

  I've checked out the full images available at http://hirise.lpl.arizona.edu/ and season to season they stay constant

  Great work, pocketmoon!

  It very well shows the alternative to CO2 jets happening: The complete cleaning away of very dark fans from the red to the greenish pic.

  Posted January 11, 2013 9:37 PM

• by michaelaye scientist

  We believe that at least part of the cleaning process is sinking of dust through the ice, the ice cleaning itself.

  We need more rovers 😃 Or "flyers".

  We talk about humans going to mars but now technology has moved on. Robots can do more science than humans without the risk of death.

  I think these are copper sulphate / graphite geysers.

  These lit up half moon features are quite common, but what are they?

  Posted January 12, 2013 8:43 PM

• by Milkywaystars

  The blue and black mark suggests an oil spill from a satellite but the bump is better. It suggests a crater or something in the core.

  P.S.I suggest this should be seriously investigated as it is ver rare

  #duststorm. Looking at the pink tinged thing SE of the fans (looks like a jellyfish to me)

  the sun is up the top somewhere then

  Check out APF0000q37. There are more of these half moon blurry features...they're a Mars thing! Woder what they are?

  Posted January 14, 2013 7:11 PM

  Also, they are orientated at the same angle......must be a wind thing?

  Looks like a mini-mountain, maybe pushed up by the same activity that's creating the fan on the left?

  The white 'spiders' remind me of milk skin after it has boiled and is cooling......

  needs to be looked at and analysed ASAP #Interesting discovery

  wow, have seen similar - with numerous fans and craters.check out pics. where can we get further info on pic location and adjoining images?

  Posted January 15, 2013 6:37 PM

• by JellyMonster

  It is not a mini mountain. Invert the image to see a large crater. The photos are the wrong way for viewing purposes.
