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? -------------------- |

Inbetween writing Christmas cards and eating mince pies today I've been playing about with the wonderfully addictive website http://global-data.mars.asu.edu that lets you explore Mars through the eyes of spaceprobes from Viking to MRO. I like just dipping in at random, playing a kind of "martian lucky dip" if you like, and seeing what turns up. I just found something interesting... well, I think it is.
Image http://hirise.lpl.arizona.edu/PSP_005665_1800 is entitled "Change detection in Dark spot", so I thought it was worth a look... change is always a good thing on Mars, after all... into IAS Viewer and fine, looked just like one of those "fresh impact craters" to me - a dark "splash" of colour on a bright background. Zoom - and yep, right in the centre there's a small cluster of craters. But that's not what caught my eye - what made me go "hmmm" were the many dark lines and trails coming off the terrain around it. There are hundreds of them! I'm just puzzled what I'm seeing... this isn't a polar area, so the light terrain can't be frost- or snow-covered, yet it looks like something is coming out from underneath a surface layer..? Anyway, just thought it was interesting - note: not odd, interesting! - and wondered if anyone has any thoughts about it. HiRISE. What a fantastic camera! -------------------- |
