Take a moment to consider what you're actually seeing here: a truly historic event.

This mission is so expensive, and has involved the figurative blood and tears of so many extremely talented people, that it will probably always be remembered in the history of space travel, whether or not the landing itself will be successful.

(It could be argued that the value of having so many millions of people watch or follow this (whether now or later), and have the associated mind-expanding thoughts and possible subsequent ideas or decisions, is itself worth the price of this mission.)

If they pull this off I will be thoroughly impressed. I keep googling to try to find where they tested the landing system altogether as a unit and there doesn't appear to be such an event, only individual components. Can you imagine designing and testing the individual parts of a car, then assembling it and never testing the car as a whole unit and just hoping based on theory it works?

They tested it as much as they could. You can't simulate Martian gravity and the full Martian atmosphere on Earth.

Is there anything left to be done by NASA HQ? For example, are they still controlling the trajectory of the probe to Mars or is that mostly done by probe's onboard computers? I'm genuinely curious about what kind of things the HQ is doing right now. I've been watching the live stream and there's not much activity besides milling around screens and resizing windows on the huge screen.

From a Reuters piece...

"Mission control contemplated sending Curiosity one last "parameter update" on Sunday, hours before atmospheric entry, giving the vessel an exact fix on its position in space. But NASA engineers said they would likely forego that transmission because the vessel has varied so little from its ideal course.

Otherwise, controllers will have little to do but anxiously track Curiosity's progress as it flies into Mars' upper atmosphere..."

"We're all along for the ride," Seltzner said."

I noticed on the NASA TV schedule that the "Public/Education Channels" have commentary, and that the "Media Channel" has a "Clean Feed with Mission Audio Only".

The link given is for the public stream (http://www.ustream.tv/nasahdtv); the media stream is here (http://www.ustream.tv/channel/nasa-media-channel) and should be HD as well.

Is there any way to watch in VLC? I don't have Flash Player.

http://nasa-f.akamaihd.net/public_h264_700@54826 should work in any H.264 + HTTP capable video player.

Definitely much nicer than the solution I found. How did you find that so easily?

I have Flash handy, so I just utilized the Resources tab in Chrome's Web Inspector to see the video resource Flash was actually streaming.

This approach works for a large percentage of CDN-based streaming video, which rarely has any unique authentication (as sharing any kind of per-user state with the CDN edges would be quite difficult).
