I've seen so many photographs depicting falling debris, I had to make a web page dedicated to this! Of course I think it means Martians are trying to tell us how their precious planet was ruined when their atmosphere was lost and the surface of their planet was ruined forever ! And this event happened in extreme ancient times!
The analysis I use for the photos and imagery are not mean't to be exacting, only to get you closer to understanding that there is intelligent life on mars (martians). Many of the rocks you may think are rocks, are in fact highly designed sculptures, mechanical objects etc.
Nasa is trying to leak out anomalous imagery with out of course talking about it public! Though most images have been doctored, Nasa is trying to humbly and quietly nudge us along with out going too public about it vocally. Though it is work and painstaking effort to find objects in the images that have not been altered in some way!
