Damn, MSL has same speed of Spirit! 4 cm/s! I really hoped it was a bit faster!
It will require a(nother) whole life to go around! 0,144 km/h! How far is Mount Sharp?
That means it would only take 7 hours to go 1 km.
Control algorithms seem far more important than speed-over-ground, to me.
cheers, Martin

Not that it produces anywhere near enough power to drive a kilometer in 7 hours.
Design range is 200 meters per day, and most days will be far below that.

Remember there is 28 minute delay in single.
14 minute transmit time and 14 minute return time.
So you can't do anything wrong.
That is why the slow speed.

Weren't the navcams going to be capable of 15fps video? Am I imagining that. I could have swore one of the other cameras besides MARDI were capable of sequential imaging?

You've seen it before, but not like this: Visual-effects specialist Daniel Luke Fitch has assembled the high-resolution imagery showing the Curiosity rover's descent to Mars this month into a YouTube video that's as slick as his highlights reel.
The video takes advantage of pictures captured by the Mars Descent Imager, or MARDI, which is positioned on the bottom of the rover. During the "seven minutes of terror" leading up to Curiosity's landing on Aug. 5, MARDI recorded hundreds of still frames and stored them in the rover's memory. Thumbnail versions of the pictures were quickly sent back to Earth and turned into a low-resolution movie, but it's taken days to reserve the bandwidth required for transmitting the full-resolution frames.

As far as I'm concerned, that one analysis was worth its weight in gold. Fabulous instrument. I'm sure the designers & constructors are tickled to see it in action! Great work.
I'd say an individual analysis isn't fantastic on its own. My understanding is the measurements from ChemCam have a relatively low sensitivity. The Alpha Particle X-ray Spectrometer can provide much better results, but it's a contact instrument, so it requires driving up to a target and placing the APXS, which means both planning a drive and an arm operation, then sitting still for 15 minutes to several hours for the observation.
In comparison, in the very first ChemCam operation, it analyzed three targets in less time than it would take to drive to and place the arm on a single target. So it will increase the number of targets they're able to get basic data on very significantly, and save them time by allowing them to reserve APXS operations for targets already shown by ChemCam to be interesting. That makes it a fantastic instrument, probably worth far more than its weight in platinum.
Mini-TES on the Mars Exploration Rovers served a somewhat similar purpose, but could only identify basic mineralogy instead of detailed elemental composition.

Wow, Fixer! Beautiful image! And that's Mars.
But, it isn't Mons Aeolis proper is it? It's a hill of about 4 km height over the crater bottom on the mound surrounding Mons Aeolis (Mount Sharp). The true 5.5 km high summit of the real mountain, is out of sight for the rover, behind and a bit to the right of the peak of that mound in your image, and might remain so for the entire mission.

The mastcams are capable of 10 fps. Expect this to be used sparingly due to the bandwidth involved. It's possible we'll get a few sequences of arm deployments or driving, but nothing has been promised. One of the planned uses is catching dust devils in action, assuming they occur regular at this location as they have where the MER's landed.

Do we eventually have a full res version of the 360° panorama shot in first sols? Or it was not at all a full-360° and we'll never see it? I only see "fake" full-color panoramas made by stitching and colorizing navcam images!

Curiosity Drops in on Mars in High-Res
Published on Aug 23, 2012 by JPLnews
This movie from NASA's Curiosity rover shows most of the high-resolution frames acquired by the Mars Descent Imager between the jettison of the heat shield and touchdown.

Now that I know of the "encrypted" comment (T.D. nominal, RIMU stable, UHF good), hearing the audio makes it a lot more interesting to look at just some pebbles in the background.
I also think someone in the room was "muted" upon getting already enthusiast for "T.D. nominal" ("sssshhh! It's too early to speak!!") :-) .
Now somebody should prepare a video showing what could have gone wrong: skycrane crashing on the rover, or flying away before ropes are cut, and so on... :-)

I think the documentary called "Martian Mega Rover" has some cute CGI video of some of those scenarios, although it depicts the rover landing on a pretty big slope even in the normal scenario.

Wonderful video. Although for an update thread, we can place priority on the specific video and image threads to keep everything nice and tidy.
