There were about 240,000 concurrent users on the web feed at touchdown. But not a single TV news channel was covering the event live that I could find.

cnn.com is, but they're just repeating the nasa feed unmodified.

Be thankful.

They could have cutover to Ryan Seacrest interviewing a rock.

what's up with all the "what does it mean for the nation"? It's a huge step for the humanity, not only the US. And the actual rover is filled with instruments from all over the world. From wiki: > ChemCam ... developed by the Los Alamos National Laboratory and French CESR > Alpha-particle X-ray spectrometer ... APXS was developed by Canadian Space agency. > Sample analysis at Mars ... was developed by Goddard Space f…

The US paid for the vast majority and are responsible for getting this to Mars. The crazy landing, and $2.5 billion at risk on a project with a 30% historic success rate, wase not shared. US total annual space spending is about $60 billion a year. The entire rest of the world combined is only about $22. The entire EU is under $6 billion. This is an American achievement. If you aren't from the US, you should try to en…

NASA's budget is about 18B, not all of which is space related. Where does your other 42B come from?

The total 2010 US Space budget was $64.6B. The entire rest of the world combined spent only $22.5B. NASA's 2010 budget was $18.7B, 83% of the spending for the rest of the world. The Air Force Space Command is the remainder, they run many projects, including GPS.

One thing they mentioned is that one advantage to the sky hook is that it will be a soft landing - no dust will go everywhere and land on delicate instruments. Isn't this easily solvable with some sort of skin it can just dispose of once the dust has settled?

They do have covers on the lenses that will be removed, but I don't think it would be practical to put removable covers everywhere. What would happen if the 'skin' didn't come off?

Thanks for the info, but shouldn't we be comparing civilian space budgets? Obviously dual use projects like GPS should be included but most of that 40B+ is purely military in nature.

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.

Plenty to do, since monitoring and understanding all of the incoming data is most of what operations is, but in this case, no commands were sent while the stream was live.

OK, but it's a pretty big deal for the U.S. Those are great contributions by other nations. However, if Canada had decided to produce an Alpha-particle X-ray spectrometer, it's not as if NASA would not have been able to make this possible. The same can probably said for every other component. This doesn't diminish any of their contributions and they should all be proud but I don't think we should downplay what this means for the U.S. and simply say "Aw shucks, this is humanity." As well, all of those involved in the press conference I saw acknowledged their international partners.

It would be almost impossible to get a reliable estimate for other countries, most do not have separate civilian and military space programs like the US. For example, the ESA is building Galileo, a positioning system similar to GPS, primarily for strategic military needs. The Russians and the Chinese, who make up almost the entire remainder of global space spending after the EU, spend quite a bit on military space, but there is not reliable data. In fact, there is basically no data on Chinese spending at all, it's an industry estimate of their spending based on outside observations. In addition, there is some crossover each way. Hubble, in particular, received substantial benefit from military research into spy satellites, not to mention the recent gift of two space telescopes to NASA from NRO. At best it's unclear how to decouple the spending in the US, and nearly impossible internationally. I believe going with the totals is fair, as the approximate civilian to military ratio would be pretty close internationally, given the obvious military implications of space, like ICBM's and spying, the interchangeable nature of the fundamental research in each field (e.g. ICBM guidance systems research can be applied to landing on Mars, spy satellites are space telescopes if you turn them around), and the countries involved.

As much as anything, those guys were doing their bit to secure funding at a time when their budgets are under really huge pressure. A lot of that stuff is aimed at Senators who decide budgets. They respond well to this kind of thing. I wouldn't be surprised if Charles Bolden also has political ambitions, that was quite a 'statesman-like' speech he gave.

It also plays well to the people who don't know any better, the people who say 'why are we spending all this money on space when I can't get a job?'. You'll notice that the straighter and more senior heads - Pete Theisinger the PM, and John Grotzinger the chief scientist, did not go all Team America during the press conference, but did make similar points - 'The money isn't sent to Mars, it's spent here on Earth' - again speaking to the pressure that they're under.

I see a company called Euroconsult publishes estimates of governmental space expenditures. Unfortunately it costs over 4000 euro! But a summery is available here:
