Now, I'm usually a RAW images man - I like putting together vistas that were captured in the very recent past, and 'hot off the press' if you like.

However, I've finally got around to playing with Bjorn's awesome IMG2PNG utility and have calibrated some early Cassini views of Jupiter (the difference between the calibrated and non-calibrated images is quite staggering). Due to the lack of any RED filters, the following view was constructed using a synthetic red (sort of GREEN minus BLUE, in effect). I'm really pleased with the result:

Thanks Bjorn! wink.gif

QUOTE
If you recall the liftoff movie from Apollo 15 (and verbal comments from other crews), big pieces of thermal blanket (the MESA blanket, for example) have been known to blow out and away from the LM upon APS ignition. On Apollo 15, a big blanket narrowly missed knocking over the ALSEP central station and flew on downrange at least another half a kilometer or more.


That very piece of insulation was indeed imaged by LRO:

For the 20th anniversary of the Neptune encounter, I've uploaded the official JPL animation of the flyby to YouTube:

I have very fond memories of watching this clip over and over again as a rather eager 9-year old!

Curiously, the LRV itself isn't visible, although the shadow it casts towards the east certainly is.

For a different perspective on the whole issue of moons casting shadows on the rings, here is a mosaic of a couple of HST pictures of Saturn (taken back in 1995, as far as I can recall):

Just in case an attempt at imaging the the Apollo 17 landing site really is imminent, I thought I would post this mosaic I made a while ago from frames taken from the 16-mm ascent film shot just after pitch-over. As far as I'm aware, this is currently the best overhead view of the region where Challenger landed, and it would be interesting to compare this to the putative LRO view of the same area:

As a proud Plymothian (check my profile), it's a pity I couldn't make it to the event, but I am proud that the same city historically associated with the Pilgrim Fathers has hosted this joint exhibition between NASA and ESA.

Here's the online version of the article in my local paper covering the meeting:

Good grief! ohmy.gif This is really coming along Stephen. I can only hope that one of the few images I contributed to this project makes the final cut! biggrin.gif
