You could totally use them to navigate, especially if Jupiter was above a horizon (as in, not directly overhead so you could distinguish easily between east and west).<br /><br />Spot on about moving north or south. I think (without working it out or anything) that you must still see it from the poles, then once you started moving towards the ante-Jovian point (yes, I just made that word up) it would fall beneath the horizon.Tsana Dolichvahttps://www.blogger.com/profile/16213478548320312760noreply@blogger.comtag:blogger.com,1999:blog-119383823552885882.post-41170791037809348442011-05-27T09:19:36.813+02:002011-05-27T09:19:36.813+02:00I was kinda afraid that Jupiter would take up pret...I was kinda afraid that Jupiter would take up pretty much all of the sky on Io. I'm wondering if there is an easy way to tell which way the stripes would run. I suspect it has something to do with the latitude on the body you're standing on, and the inclination of the orbit. All that stuff tends to do my head in. I figure if you're at the subjovia point on either, Jupiter would be straight above, but I don't know which way you'd see the stripes. Any further north of south would bring Jupiter closer to the north or south horizon, and the same for east or west. Again, I have no idea about the stripes.Anonymousnoreply@blogger.com
