I drew them, you get them! Call it a musing. Graphs compiled from Onlinery relating to Ariane ‘flight 197’, October 2010. The first two show acceleration from 0-9400 metres per second (much faster than the fastest combustible known to man), within 1500 seconds (25 minutes). The third graph tracks altitude over the time period. Note the burst of speed and altitude in the final throes of burn-time – from 350-650km, and 8800-9400m/s. Rockets don't work in a vacuum, but they’re bloody amazing on paper.

REAL OR FAKE? ("Proton lift off video")
Someone on YT ("Michail Dugov") has called me mentally ill for suggesting this could be fake imagery...
Proton Launch of SES-6 on ILS Proton-M from Baikonur: http://www.youtube.com/watch?v=LMwDASkWPJU
Perhaps Michail is the Russian artist responsible for this colorful cartoon?

Re: Satellites : general discussion and musings
If you really want to piss off Michail Dugov, tell him vodka originated in Poland.
And then tell him the bad news: no Russian has been in space.
But the good news is neither has anyone else

Re: Satellites : general discussion and musings
Hehe - if I told him about the vodka he'd probably get mad at me. I tend to avoid making people angry. Here's what I responded to his last comment which went like this: "This is not slow motion man....The mass of the rocket creates an illusion of slow speed. Watch every large rocket launch."Starbucked wrote:If you really want to piss off Michail Dugov, tell him vodka originated in Poland.

My reply:
It is no illusion, Michail: watch this ATLAS V launch video: watch?v=PYwQPBFl6TA
As you can measure and verify for yourself, It takes 8sec for this ATLAS rocket to travel the distance of its own height (58m), which means that its average speed right after take-off is 16.2mph (or 26.1km/h). A man can run faster than that.
See, I have watched a great many large rocket launches. None of them appear realistic. The world of rocketry is a gigantic scam - but you're free to buy into it if you wish.
Here it is: watch between 1:13 and 1:21. That's the eight seconds it takes for the ATLAS to travel its own height...

I think the launch is slightly less dire than the Proton Gas Burner
but it's a close call. I keep hearing it: Thunderbirds are GO! Da dada Daa!
Re infringement of penile code: apologies. Of all the online images of the Ariane model, no other seemed to be so exactly shaped.

"The unmanned Russian Proton-M rocket launched from the Baikonur Cosmodrome in Kazakhstanat 10:38 p.m. EDT (0238 GMT). The crash of the 17-story booster destroyed three onboard navigation satellites, which were worth almost $200 million."

An amateur video of the launch, crash, and resulting KABOOM!
full link: http://www.youtube.com/watch?v=Zl12dXYcUTo
From impact to sound of the crash reaching the camera is around 10 seconds, meaning they are around 3 kilometers from the crash sight.
With an explosion of that magnitude I would expect to see a shock wave radiate from the crash zone, but there is none.
What do they fill the Proton M with? Gunpowder?

Yes, Starbucked... and here's the official 'video' of that failed July1 2013 launch - as aired on TV:Starbucked wrote:"The unmanned Russian Proton-M rocket launched from the Baikonur Cosmodrome in Kazakhstanat 10:38 p.m. EDT (0238 GMT).

TITLE: "Russian Proton-M rocket explodes after flying wildly out of control"
[EDIT: Attempted to fix broken YouTube link. -HP Dec. 21, 2017]
Not only is the official "video" far lower quality than the "amateur video", but it also includes what looks like a shot taken from almost the same angle as the "amateur" video (plus a few 'raindrops' on camera lens)... How silly can this get?
More importantly, how can we still have modern, expensive rockets falling out of the sky, in 2013 - after a mere few seconds of flight ? Apparently, as many as five Proton rockets have failed since 2010. This, after over five decades and untold billions allegedly spent refining this technology? Are our rocket scientists / engineers the most hopelessly inept and incompetent people on this planet?
Re: Satellites : general discussion and musings
indeed. It always strikes me how badly overplayed the "amateur" videos are in trying to give a real world feel to their "official" toons — but failing badly. The ridiculous sound effects, fake emotion and, of course, the obligatory bird! http://www.youtube.com/watch?v=Zl12dXYcUTosimonshack wrote:How silly can this get?

Re: Satellites : general discussion and musings
The only conclusion I've yet to draw from any such fake "disaster" (unmanned) is that they are attempting to establish a bit of realism, here, as well as manufacture a bit of tension and anticipation. Regarding the former, it's understandable that they wouldn't want their campaign to look too perfect, but they've gone way too far in the opposite direction. As for the latter, it allows for opportunities to engage the population not just on an intellectual level, but also an emotional one. (edit: Not to say that multitudes of people are not already emotionally invested in the lofty dreams of space exploration).

Re: Satellites : general discussion and musings
Yet, not once did a rocket crash, on take-off or otherwise, during the whole Apollo mission half a century ago. The epithet 'Rocket Scientist' has lost a bit of its lustre since the good old days when manned rockets were as reliable as a Toyota.
Re: Satellites : general discussion and musings
However, the most toonish of it all was the flight of the bumblebee - err I mean that penile contraption of course. Our dear Sceppy may rest in peace as far as this forum is concerned, but his golden rule that there's no such thing as a "hovering" rocket may still apply.Maat wrote: indeed.

Also, observe the smoke appearing at 0:43. It curls away in a manner suggesting a small object close to the viewer, not a 17-story booster 3 miles away.

Re: Satellites : general discussion and musings
Yes, I found the "no hovering rocket" idea very thought provoking/perception shifting too. It got me thinking and then wondering if it might not be quite such a simple clue as it would appear; maybe even a bit misleading. What I mean is, because we can see that all the "launch footage" we're shown is recycled cgi animation, we naturally look for every possible real world comparison, physics etc. to prove it more conclusively.rusty wrote:However, the most toonish of it all was the flight of the bumblebee - err I mean that penile contraption of course.

My question is, what if it's more a matter of their attempt to reproduce a real rocket's takeoff speed in animation that's off (i.e. close but no prize)? Thus making it more cartoonish by the combination/accumulation of unreality errors. For instance, were they trying to mimic the old German footage of V2 rockets from 1942, but miscalculated because those followed a (successful) rocket's rise with the camera, making the actual speed/distance traveled hard to determine accurately without visual reference.
These videos, supposedly original German footage of V2 rockets, show a series of launches; one at 0:53 then about 10 from 1:31:

Great post, Maat!
Sorry, but I cannot resist the temptation to (re)post this WALT DISNEY - VON BRAUN clip from 1959 ... everyone needs to see this hilarious piece of film which heralded the bogus space travel fables !
