Best to wait for the laminated edition, I think, if you're prone to drooling, nprev!

Here's a version of the ascent mosaic that is more extended in the direction of the rille:

Here's a couple of views of the Apollo 15 landing site, separated by nearly 40 years; top is a mosaic of stills from the film shot during the ascent into lunar orbit; below that is a recent view from LRO that Phil posted in another thread:

Took this shot of Venus, Mercury and a very young Moon last night here in Plymouth. Mercury was completely invisible to the naked eye, but showed up in the images pretty well.

This is a screenshot from the most recent episode of The Sky at Night - can anyone spot the rather 'large' error?

It looks like a real labour of love, Phil.

And boy do some of those grooves look like heavilly eroded uber-crater chains...

This apparition was a first for me too. Having never seen it before, I was ecstatic to spot Mercury twinkling beneath a ribbon of cloud, just after leaving Tesco on Saturday evening. On arriving home, I rushed upstairs and managed to capture this shot of the two inner planets hovering over the rooftops of Plymouth:

Thanks for the heads-up charbobob! I've adjusted the image and replaced the incorrect version in my previous post.

Y'know, there comes a time when a lone emoticon just seems so woefully inadequate...



Great stuff as usual, Gordan!

That is just a beautiful example of image processing you've achieved there Machi. Nice one!

Phil, you've even made the headlines on FARK! laugh.gif

Glad you got a kick out of my little experiment Emily; I went ahead and added the coloured meridians to the simulated views as per your suggestion (see my original post).

I enjoyed your latest blog entry elucidating the possible reasons why the skeet-shoot encounter didn't entirely go to plan. For the UMSF folks who haven't seen or read it yet, you can find the article here:

http://www.planetary.org/blog/article/00002383/

Interestingly, this isn't the first time that a non-targeted flyby of Helene has produced some poorly-framed views; the of images taken in November 2008 show the moon right at the edge of the frame, slowly moving out of sight as the sequence progresses:

Here's another attempt of making sense of the many different views of this little moon:

Very nice work indeed, Machi. smile.gif Here's my attempt to link together all of the medium-resolution views of this moon, using some of its more prominent surface features:

In this montage, the two views to the right are wide-angle shots of Helene which I presume were taken during the unsuccessful skeet-shoot sequence, while the left-most view is a NAC frame taken as Cassini was receding from the moon with Saturn providing a backdrop:

I guess this will be the highest resolution view of Helene for a while, then...
