How do they do it - Space Shuttle engine test

[geomodelrailroader]

Brits you keep getting your facts mixed up 1. a booster is not an engine 2. Discovery did not blow it was Columbia and Challenger that blew up 3. we have thee orbiters not 4 not 2 three and the fourth reason is Brits never seen a shuttle launched.

Thanks very much for that. That was a good overview - now let's get to the meat. Let's zero in on the details. It is just absolutely amazing that little rig produces that much horsepower. I've got to go to work, but will somebody please do the calculations and tell me what a 2012 Boss 302 Mustang will run the quarter in with that kind of a push?

This kind of sensationalist, gee-whizz 'documentary' is one of the reasons why I cancelled my Sky subscription after 6 years of watching, over and over the same sort of crap on the Discovery channel and the other so-called documentary channels. I once bought a book, "Rocket Men" by Craig Nelson which was reputed to be about the first men on the Moon. It contained so many egregious errors I gave up at page 116. I am sure Nelson wrote the script for this crappy SSME article - the style is familiar

[Esudao]

what the hell ... how has letting the exhaust flow around a curve after it's left the engine anything to do with the engine not lifting up? ???

someone had no clue making this documentary.

[Gioagla]

guys !! you re amazing !! this is called science !

[SenseiGrove]

7:27... you're welcome.

In contrast to the commentary suggesting that the SSME was one of the most powerful engines, just one of the five F-1 engines of the saturn V first stage is more powerful than he combined power of ALL three of the Space Shuttle main engines.

[manosdepiedros]

@063209dr true however, the SSME is the most efficient liquid propellant engine in use (or was in use) with a specific impulse of about twice that of the F-1 engine [~450s vs ~260s]

[tom1161]

When the hell was Discovery "lost"?

[jaafaransari13]

@tom1161 I'm wondering the same thing, haha

[FSEVENMAN]

This clip sucked.

The water system is solely to reduce the decibels produced when the engine is ignited. It is called a water sound suppression system. It has no cooling function.

[indoorherbivore]

He actually said that diverting the thrust sideways in the exhaust bucket is how they keep the test stand from taking off. Just...wow.

[drtracernum20]

loss of Discovery huh, sometimes these tv programs really annoy me. dont they have people that investigate the facts before they script and tape? and what was the editor doing before final cutting of the footage?

[nop8051]

Some of things he said is complete bullshit. Why wont they take bloody nasa engineer to explain what we are seeing.

[computergames5]

Lost of Discovery?!?!?!? -___-

[blgibbs6]

@computergames5 I heard "Discovery" as well!

[computergames5]

@blgibbs6 Of course you did, how can't u hear it?? Lol.

[MarsFKA]

I lasted for 35 seconds, then stopped it. This is typical Discovery Channel crap.

[alekskelec]

first faulse thing that they said, is that space shuttle discovery wwas lost, but it wasn't, I dont know which space shuttle where they thinging about, eather space shuttle Columbia, or Challanger.

[nillchen]

"galactic bus" ...yeah right, 300 kms above Earth...more like a high flying plane! nevertheless very impressive though.

[lokideasgard]

0:27 "tragic loss of space shuttle Discovery" ..... uh last time I checked that wasn't one of the shuttles that was lost.

[locomike1219]

@lokideasgard seriously, how do you screw that one up??
