Stu surely would have volunteered!
Stunning, Bjorn. Of all the Jupiter images I've seen, yours make it look most like a place, if you know what I mean. -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

I had to put this up on my 42" HDTV to begin to appreciate the magnitude of the detail in this image. The swirls and eddies north of (above) the GRS reminded me of fractals. One gets the impression that you could zoom into this picture and see the swirls turn into infinitely more swirls. BTW, the Jupiter movies in this thread look pretty darned good on a 42" HDTV, too!

Every time you post one of your images, Bjorn, it's like I'm seeing a picture taken during a whole new, top secret Jupiter mission. Thank you for taking us to Jupiter again. Just stunning.

Astounding Bjorn! I really love your work. I'd be really interested in hearing more about the process in creating these fantastic mosaics. I understand the basic jist of the layering techniques but to get everything lined up just right with the right shading must take forever.
I also ran your enhanced version through a couple filters to pull out a little more clarity. I never cease to be amazed by the images that the Voyager probes produced. Far as I can tell, the only competition has been from Cassini which is disspointing. -------------------- |

To be fair, Galileo did very well considering the challenges that mission faced.
But, man...Bjorn just pulls every detail out of this data; he's a wizard. Those 'curdles' to the SE of the GRS fascinate me; hard to believe we're looking at a laminar flow the size of some worlds... -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

Wow....that is awesome! Nice work, Bjorn!!
The comma-like details of the cute littlw swirls in the northern margin are so stunningly crisp. I'd never noticed how the pattern doesn't match staight-line coloring.... Hinting that some of the color must be from a higher atmospheric layer.. Each tiny section of this is a masterpiece. I could stare at this for days.... Well done! -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

The more I stare at this the more I see! (Like those "teeny"* little puffball clouds in the extreme NW corner)
*"teeny" = the size of a large metropolitan area on Earth. Amazing! I want this as a tile floor or countertop! -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

Those 'curdles' to the SE of the GRS fascinate me; hard to believe we're looking at a laminar flow the size of some worlds... It really is sad. Having worked with a few tiny lossless/nearly lossless image fragments from that mission, its camera was spectacular. However, on most images, especially those of Jupiter itself, the JPEG-like artifacts are horrendous due to the compression that was necessary. -------------------- |

Brilliant Bjorn... just brilliant.
I've decided not to re-decorate the living room; instead, I'm going to cover the walls with posters of your amazing mosaics! -------------------- |

Thought I would clarify that I never meant to belittle the Galileo probe. It returned really fantastic data that actually benefited Cassini greatly. Had the main antenna extended, the images returned would have been phenomenal. The images that were returned were nothing to be really upset over either because many of them were great, especially those of Io. Galileo is a great reminder of the complexity in these missions and the absolute perfection that has to be maintained to have any success in them.
In my opinion, any human creation that is able to survive extreme G-forces while being lifted off this planet, to travel millions of kilometers to another planet, and then to be remotely operated by humans from millions of kilometers away, all the while being subjected to extremes in temperatures and radiation, is nothing short of mind boggling and a wonder of human achievement. Galileo was far from being a failure. -------------------- |

Galileo is a great reminder of the complexity in these missions and the absolute perfection that has to be maintained to have any success in them. If nothing else, NASA have hopefully learned never to build a probe with an unfolding 'umbrella' antenna again... . Moving parts = bad! QUOTE Galileo was far from being a failure. Well, it's good that it managed to send back something useful (at least, the stuff that wasn't horribly butchered by compression blocks), but I still think it's a crying shame that it couldn't take the images that were originally planned. The gravity data at least went some way to making up for it though IMO. |

Careful on the broad assumptions there EDG, that antenna had very high heritage from the TDRSS antenna design. It was a low risk, good flight heritage component. There are moving components in spacecraft. reaction wheels, antenna gimbals, solar array gimbals.... heck, it's thought the most recent Delta IV heavy launch contained a NRO spacecraft with an antenna of many TENS of metres as an in space deployable.
NASA far from learnt to never build a probe with an unfolding umbrella antenna again - they are on the TDRSS sats launch SINCE galileo - infact two on each spacecraft http://en.wikipedia.org/wiki/Tracking_and_...Relay_Satellite Six TDRS launches have taken place since Galileo - for a total of 12 very very similar antennae, all of which deployed without incident. |

NASA has learned never to build a probe with an umbrella antenna and leave it in waiting for a decade that included two truck rides across the country, all the while never checking to see if it was still lubricated or if it has been damaged.
