Those Martian boulders are alive I'm telling you...

I have brought these two images together on one page, so that people can witness a transformation that has (or is) taking place. As usual, the photos have been rotated to help differentiate between ridges an channels.
Top picture, Betty Boop - lower one, Paddington Bear?

It looks to me more like corrosion, perhaps contaminated in some way? The lower photo has a hole in the middle where there wasn't one before. Also, the boulder on the right has turned black and looks to be breaking up.
Maybe the scientists can help out, although they seem to have gone a bit quiet lately (probably resting) 😃.

Could it be just an "iceberg" of sorts? melting away?

Yes it could - a very dirty iceberg.
What's happened there?

Interesting that the apparantly broken down lumps seem to give similay shadow lenghths. Great if we could get full data on these, including the solar angle details.Could be just icy surface subliming, and the albedo dropping. Heck! whatever~ it's fascinating~ thanks Jelly for the stimulation! 😃 ~ Pete

Have you thought about putting in a HiView request for a new image? Would be really interesting to see what the objects look like two years (or more) later.

Kitharode, it's an Inca City image, if we can find the right spot there will likely be 5 seasons worth of images to play with

I didn't know you could do that sort of thing?
I think the image featured in another post but I am unable to find it 😦

My mistake JM, it's HiWish (not HiView) - http://www.uahirise.org/hiwish/
I think you're right that 'Betty Boop' appeared in another post. I'll keep my eyes open for it.
Wassock: Thanks for that. We need the APF number for sure.

Well done wassock. I was obviously looking in the wrong place.

OK Here we go
PSP_003593_0985 3 May 07 SL 230.7
ESP_012467_0985 24 March 09 SL 233.6
ESP_021460_0985 23 February 11 SL242.3
ESP_030084_0985 26 December 12 SL232.9
ESP_038510_0985 14 October 14 SL 215
And by way of comparison couple of close ups
2009 (SL 233.6
2014 (SL 215)
On balance I'd go for "not the same"

Interesting. Are you looking to see if the boulders are moving or that the blotches are different from year to year?
Cheers,

The boulders appear to be static but their form seems to change over time.

Started out just trying to see if I can find the same boulder year on year, then tried to get them all as close to time of year as possible and ice free (ish).. They look slightly different each year which is maybe down to ice hanging on, but I'm tending towards think there's something different between 2009 and 20014. Will try the same tricv on some of the other clusters nearbye
