wish i had a bigger version of the video but it still looks cool!

kaguya takes images of lunar surface

NASA did, back when all we were doing was flying to our nearest neighbor. The Ranger and Surveyor series both had TV cameras onboard. I'm sure you've seen footage of the live video sent back during the Apollo days.
Also, the cameras on the lunar rovers on Apollo 15, 16, and 17 were remote controlled. The rovers were parked in such a manner that the camera could tilt up to follow the launch of the ascent stage of the LM.
So.. yeah, been there done that, check the archive.

Which NASA probes are you talking about? Because we've got the closest we can get to video of dust devils on the surface of MARS coming back from Spirit and Opportunity.
Let's not forget that the time it takes for a signal to even come from Mars to Earth would be detrimental to video feeds. You're talking trying to broadcast a video signal from an orbiter that's in constant motion around a planet that's also in constant motion trying to reach a stationary receiver on Earth, which is also constantly in motion. If you're willing to do the maths to figure that out for the JPL, I'll bet they'd be willing to listen. Until we can break the subspace barrier (to use a fictional method), video is probably out of the picture for a while yet.

Actually the math is not difficult at all. Mars probes have been using DSN's 8-hour tracks for data downlink and video telemetry can be treated like any other data. The main problem is actually the bandwidth however a transition to the Ka-band could resolve that issue.
Huh? I thought that video feed is from a Japanese probe?
Good video, thanks.
There is little scientific value in this movie sequence, but DANG does it look cool! This is a view that no one has seen since the 1970s, and it's pretty inspiring. We'll be back there in just over a decade, folks!

I agree that in general a movie sequence does not have the scientifc value of carefully taken stills.
Per my previous posting Ranger and Surveyors were unmanned, and had TV cameras. Several recent Delta rocket launches featured live video from the booster during ascent.
If you can solve the issue of getting sufficient bandwidth over a distance of more that a light-minute or so of distance, I'm sure that NASA will be happy to incorporate live streaming video on everything they fly. Until then, they have a very small pipeline to send all the command and control, telemetry, and science data traffic over.
It's about 10 light minutes one way to Mars, that's a bit outisde the TTL for the average TCP/IP packet.

This is totally incorrect.
Adventure is nice though. It's a good bouns. But to use the example of Cassini, if the only thing you think we got from it was pretty pictures then you're doing all the scientists working on the project an extremely large and sad disservice.
I don't think you understand the difference in the amount of data or the tiny amount of bandwidth that is available when a transmission source is that distant, moving at a high rate of speed, oh, yeah, and your recieving antennas can only face the source for a limited amount of time due to that whole spinning earth thing...
