Busy preparing a new Outreach talk here, and have been trying to find some images to illustrate the "power" of HiRISE for a non-technical audience. Playing about with - sorry, carefully looking at the images on - the addictive Mars Global Data site I found a cute landslide on Xanthe Terra that does the trick nicely. Using the IAS Viewer you can zoom in on the boulders carried down the slope by the landslide and even see cracks and splits in them... unbelievable...!
Anyone else got any fave examples? -------------------- |

There was some concern before that HiRise's resolution would actually be greater than the Mars atmosphere would allow due to twinkling. Has anyone taken a look at that again? What's the new maximum theoretical resolution from orbit? Less than 5cm?

What's the new maximum theoretical resolution from orbit? Less than 5cm? I don't know the exact numbers but from looking at many hundreds of HiRise image it does "feel" like the highest resolution level indeed lacks some of the "crispness" of the larger scale zoom levels ... don't know if this is due to atmosphere twinkling or other optical and/or image processing effects though .... |
