I don't know if anyone's posted this yet...but it's definitely worth a re-post.
I figured they would try something like this again. http://geekcounterpoint.net/files/category-10.html Just wait until they turn that bad boy towards Earth... [Edit: Image no longer available] -------------------- Mayor: Er, Master Betty, what is the Evil Council's plan?
Master Betty: Nyah. Haha. It is EVIL, it is so EVIL. It is a bad, bad plan, which will hurt many... people... who are good. I think it's great that it's so bad. -Kung Pow: Enter the Fist |

I can't believe what thought process just went through my head.
"Oh yeah - that Ikonos image is the same sort of quality for Jupiter as HiRISE managed. Those Mars pics from Ikonos are good - I wonder what Mars would look like through HiRISE" Duhhh Doug |

To be fair, orbital positions have to be taken into account. When Ikonos imaged Jupiter on October 27, 1999, it was 49.7" across as seen from earth, or you could say it covered 1940 square arc seconds.. From Mars, on January 11, 2007, when this image was taken, Jupiter was 50.9" across, or 2035 square arc seconds. In other words, its disk was only 4.9 percent larger. Keep in mind that my math is very crude here, but the proportions are right. I worked with Jupiter as a sphere, ignoring polar flattening.
