Hi MeteorWayne.<br /><br />Thank you very much for your ongoing support.<br /><br />There has been a lot of work put in this thread. First to find the images, then to crop & enhance.<br /><br />Then to discriminate what might be interesting for the viewer.<br /><br />These are fantastic, but very rarely seen images & anyone with an interest in planetary <br />science will hopefully appreciate my efforts.<br /><br />I know compared to Anthmartian & rlb2, I am a real amateur, but I try my best.<br /><br />Andrew Brown. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

Last one for tonight (I still have more).<br /><br />Please, I hope no one complains about me spamming or for being a troll.<br /><br />I have done a mass post tonight, because:<br /><br />1) I have had equipment / connection problems of late.<br /><br />2). I really want to share these very rarely seen images that I have worked on.<br /><br />3). Equipment / connecton has worked well, so posted whilst the going was good.<br /><br />I am doing some research on these objects, but will provide more as I go on.<br /><br />It is getting late here.

Great pics <img src="/images/icons/smile.gif" /><br />Thanks for your efforts and for sharing. <div class="Discussion_UserSignature"> </div>

 

[3488]

Hi Nimbus.<br /><br />Thank you very much. <img src="/images/icons/laugh.gif" /><br /><br />What are your main areas of interest?<br /><br />This sort of feedback make my efforts seem very worthwhile.<br /><br />Please keep checking this thread.<br /><br />I have & have access to more very rarely seen images & will do more later when <br />I have time.<br /><br />I just wanted to share these & I am also researching them. I will probably edit the texts<br />on the existing posts above, when I have assimilated the information (like The Borg) <img src="/images/icons/crazy.gif" /> .<br /><br />I have enjoyed doing this & Ganymede & Callisto are often overlooked in favour of their <br />more exciting & active inner neighbours, Io & Europa.<br /><br />BTW I am trying to pursue further Io studies, with getting a lander / orbiter mission approved, although technically it <br />is very difficult due to enormous radiation doses.<br /><br />My renewed interest was partially sparked by H2Ouniverse (Joel) who was very kind <br />enough to tip me off about a future proposed Ganymede orbiter. How that escaped me <br />I do not know, as this is something I follow very closely.<br /><br />I hope a lander (better still a rover) will be sent too, euipped with panoramic cameras <br />& a seismometer.<br /><br />Andrew Brown. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.

Callisto. <br /><br />Dusty craters. <br /><br />Close up of the aforesaid mentioned landslide in the crater. <br /><br />The surface gravity on Callisto is 11.66% of that on Earth, or just a shade over one ninth. <br /><br />Even allowing for that, slumping material can still fall pretty quickly & gather momentum. <br /><br />This landslide is at most a few hundred metres long, (exact scale currently not known, <br />needs researching). <br /><br />The material that slumped appears to be similar to the dark dusty stuff that coats much <br />of the surface of the Solar System's third largest moon.<br /><br />It appears to be like like the huge landslide on the Saturn moon Iapetus.<br /><br />In many ways in fact Callisto & Iapetus are similar. Both contain a lot of ice, both are heavily cratered,<br />both have large amounts of dust & both are large 'outliers' of the major moons.<br /><br />Of course, Callisto is considerably larger & more massive, does not have the huge albedo variation<br />& of course does not have a lofty equatorial mountain belt!!!!<br /><br />Galileo Spacecraft. <br /><br />Credit: NASA/JPL. <br /><br />Andrew Brown. <div class="Discussion_UserSignature"> <p><font color="#000080">"I suddenly noticed an anomaly to the left of Io, just off the rim of that world.
