Okay, the Hyperion photos are now online. Here's an example. Bit smaller than I expected. I wonder if the formation on top of the moon is a large crater? Reminds the huge crater on asteroid Vesta. If that's so, only Rhea and Enceladus of the "classic" moons lack giant craters (relative to moon's size).



Pallene, one of the satellites discovered in last year. Seems to be an elongated object.



Atlas. Looks really weird.



Pandora. Little overexposed in every image.



Another shot of Atlas. Look at that refraction! (Sorry for the wrong term!)



Pan within the Encke Gap. It really seems to be lemon-shaped.



Prometheus.



Helene. Its shape is similar in the Voyager photo, but this image is overexposed.



Telesto. Also overexposed. Not much to see, except that it is not perfectly round.

No it doesn't... it looks like any other alien craft.

Three in one:

One view, multiple worlds

I'm afraid you've been ToSeeked in this very thread.

(Great picture, BTW.)

According to this page, Pallene was actually first observed by Voyager 2, with the discovery image first identifed by Synnott in 1995.

I looked up, just not far enough!

Today's picture: Embedded Atlas



Atlas looks awfully large compared to the rings, but that's because the rings are extremely thin.

That's true. Voyager 2 saw it, but it couldn't be recovered. Therefore it was officially discovered in 2004. There are other similar cases, where a new moon was detected but couldn't be verified (Epimetheus/Janus, Themisto and Proteus for example).

Jupiter's upper atmosphere must be really dense to produce that distortion, almost like putting a stick in a bucket of water.

I was too hasty . There are images (or should be, if the image release system was not buggy!) of Hyperion from ~300,000 km, like this one. Cassini came as close as 150,000 km from Hyperion, providing images as sharp as 1 km/pixel or better.

Cassini will have a targeted flyby on September, when it should come within 500 km of the moon.

Finally the Hyperion photos are on-line.



Really weird object.

Unfortunately brightness levels are poorly scretched in the images so surface details are not visible in many of the images.

It does look like a chunk of pumice.

Some interesting images of Enceladus posted. Are those rounded parallel ridges for real?

Well, I guess I'd better start collecting these moon pictures. I was waiting for them all to get in but the stream doesn't seem to be letting up. =D>

I've quickly put together a HYPERION FLYBY MOVIE using some of the Cassini raw images taken through the UV filter.

That's slick, I give it four stars. It thought the plot was a little weak in spots but the acting was great, well done. =D>

Nahhh... it'a fake, I didn't see any stars at all 8)

Nice work Ian R =D>

Thanks guys! :wink:

(I can add some stars and perhaps the odd lingerie model if you want...)

Bad news: It appears that almost all the Hyperion closeup images are oversaturated and are not salvageable.
