rev 152 is now up
mostly routine obs, plus one non-targeted encounter of Hyperion


--------------------
I'm one of the most durable and fervent advocates of space exploration, but my take is that we could do it robotically at far less cost and far greater quantity and quality of results.

A non-targeted Hyperion encounter this rev & next. Good! We haven't had any good looks at H. in some time!

And it promises to be a very good look - It's the closest flyby of Hyperion for the rest of the mission, and probably our best view of this moon for a few decades to come..
Resolution should be comparable to this: (though at a lesser phase angle)

I'm not certain, but I believe due to the chaotic rotation, it's not possible yet to predict accurately at which areas the cameras are pointing during Hyperion encounters - the sequence planners don't know exactly which part of the moon will be visible during the flyby.
Good thing is there'll almost certainly be some improved resolution for parts of the moon during the upcoming encounter. smile.gif

After all, the encounter is merely sponging off of a fortuitous alignment of the moons... rolleyes.gif

jasedm true
i ended up using the existing shape model and manually making it fit
as to weather north is up ?? who knows . That though is something that needs fixing (north is to the right )

Nice pictures of Hyperion are now online:

A long time we did not get such great pictures of the Chaotic Sponge Moon !
Best regards,

Considering that Dawn is at Vesta with its big crater, I am glad that the Bond-Lassell crater was in view this time around. Great views of the central mound of that crater.

Wow! about 4 pages of images--And about every possible filter at low phase angle from multiple distances.

Hyperion crescent. Unfortunate that the "nose" got cut off in the NACs. I substituted a bit from a distant WAC but it doesn't hold up well to close scrutiny.

Great crescent mosaic , Emily !
I'm happy that Hyperion comes back in light !
I especially like this picture:
http://saturn.jpl.nasa.gov/multimedia/imag...9/N00174904.jpg
From this point of view, Hyperion seems indeed to have a much more regular Vesta-like shape, which is not the case with any other pictures of this strange object.
Is the smaller basin at the top Helios ?
