When We Left Earth - Inside The Shuttle - #1

[carabinieri210]

HOW DO THEY SHIT IN OUTER SPACE??

[Lauderish]

@carabinieri210 In a toilet.

[EMD645E]

@carabinieri210 It couldn't be easy. I hear they have to be belted to the toilet.

[tlages]

@carabinieri210 Space toilets on Skylab/Shuttle/Mir/ISS. Before that they either used a diaper or a hose/bag system. Very Very unpleasant.

hmmm, I'm quite sure the Saturn V rocket is FAR more powerful than any Shuttle rocket (even with the additional fuel tanks)

[silicon212]

@FreedomLiberty21 SRBs each produce 3.1 million pounds thrust - more powerful than the F1 engines of the Saturn V by 80% - and there's two of them (6.2 million pounds thrust combined).

[FreedomLiberty21]

@silicon212 lets take into account just the first stage of burn on the Saturn V. According to the NASA website, the Saturn V's F-1 engines produced 7.648 million lb. of thrust in S-IC or stage 1 (which lasted two and a half minutes) as the Saturn V was propelled to a height of 42 miles, at a speed of 6,164 miles per hour) For later Apollo missions (15, 16, and 17) the engines were slightly modified and upgraded so that its thrust was 7.823 million lb. in S-IC.

[FreedomLiberty21]

@silicon212 in S-II or stage 2, its J-2 rocket engines produced 1.125 milion lb. of thrust and by this point the Saturn V is accelerating at 15,508 mph.

by any measure, the Saturn V was grander, more powerful and more impressive than any Shuttle rockets.

and why wouldn't it? after all this was the vehicle that took men to the Moon, by necessity it would have to be more powerful and carry a far greater payload than the Shuttle to accomplish its mission.

[FreedomLiberty21]

@silicon212 last one, sorry :)

I would HIGHLY recommend watching "When We Left Earth: The NASA Missions" a Discover Channel HD miniseries that covers NASA's efforts from the first Mercury flights to the assembling of the International Space Station (including all the Apollo Missions). It also goes into detail about the Saturn V.

FYI, if you have Netflix, its available now for instant viewing.

[a4tech357]

is this MacTaylor talking?

[ezcomander]

@a4tech357 yes it is, Gary Sinise is his name

[a4tech357]

@ezcomander yeah i didn't know his real name :D

[a4tech357]

@ezcomander yes i know

[ezcomander]

@a4tech357 glad to be of help =)

[mitchtay99]

Those SRB's are really just big bottle rockets.

[1Nekit1]

@mitchtay99 Approximately... yes =D

[KansasForever1981]

This isn't "When We Left Earth", but "Space Shuttle" from about 1995 or so. It was shown on the Discovery Channel.

[X9Intelectual]

An air bolllon can take a small camara also a small satilite to space with a little extra boost rocket. Like the spunit where the first dog went up to space. Spunit was the zise of a ball.

[GTElwood]

?

The fuel tank is empty in VAB and during rollout to pad.

Will be fueled at the pad just few hours a planned lifftoff.

[idrankthebeach]

I got the when we left earth dvd but this isnt on it. Am I missing it?

[ingareinar007]

I thought the Saturn 5 was the most powerful? Or does he mean single rockets or?

[ZaneKaminski]

Although you are right that the Saturn V is the most powerful rocket in the sense of how much payload it can take up to orbit, the Soviet/Russian Energia (only launched twice) actually had slightly more thrust on liftoff.

[ingareinar007]

I see.. Thanx. I thought the Sarurn V had the most thrust combined. Oh, I just saw an older Guinness Book of Records, where the Energia was mentioned. But I guess it is not in service anymore? Or?

[ZaneKaminski]

It was only launched twice, once where it launched the Polyus orbital weapons platform. Even though Polyus failed right after launch, Energia performed perfectly. The reason why Polyus failed is because it had to rotate 180 degrees around after it separated from the Energia, in order to fire its engines (towards the direction the orbit went) in order to speed up and therefore increase its apoapsis altitude. However, a guidance system caused Polyus to rotate 360 degrees, causing it to deorbit.

[ZaneKaminski]

The second launch was to test the Buran, the Soviet space shuttle analogue. Again, Energia performed perfectly, and after 2 orbits it deorbited itself and landed automatically only 10ft away from its target, despite a heavy crosswind.

[ingareinar007]

Thanx again. This is really interesting! I must look more into that one! :)

[mohammeddavis]

Sure as far as a single rocket engine. Each SRB pushes 2.8 million lbs. Altogether they push 4.5 million as opposed to the 7.7 million of the Saturn V which, from the name had 5 Rocketdyne F1 engines each pushing..I believe 1.7 million lbs. And yes the Saturn V still holds the title of most powerful rocket ever built.

[ingareinar007]

Thank you for the interesting information. I got at least a little bit wiser :) I think it was Frank Borman who said "We didn`t realise how powerful it was" (Apollo 8?) I belive him! I would have flipped! But the "Spaceship 2" is a good alternative. Though it is "just 5 min" of weightless, you get your astronaut wings :)

[Lakalypso]

I think the narrator is Gary Sinise...

[LenWhistler]

Yes ... it sure sounds like Gary Sinise. Makes sense that he would narrate this video since he was in Apollo 13.

[hairy0pothead]

Sounds like Keifer Sutherland

[animeguyXL2]

Hey, How come I didn't see this clips on the DVD / BD release?

[horsegrl759]

cool
