NASA STS-119 Space Shuttle Discovery Launch 2009 part 2/3

[sitarro55555]

After working on every mission, beginning to end, of the space shuttle program, the Johnson Space Center in Houston, Texas is NOT getting a Shuttle for display in their museum. Many of the Astronauts and families live in the Houston area, including the widows of the astronauts that died in the two shuttle accidents. The United States thanks them by giving a Space Shuttle to New York City to stick on a barge in a harbor next to a mothballed aircraft carrier.......... what a slap in the face.

SOO MUCH POLLUTION

[Erik0072]

@msbieber34 well it was designed to run on tree hugging panty wastes and ozone.

[Cioskar]

lol at 5:25 she got confused

[reecem123]

absolutly amazing i seen it it was at canavrel it was the best thing i have ever seen

[hedkandi999]

what happenes to the tanks taht seperate...im gues they do it in orbit and it just flaots around or do they fall back or what?

[ishallkillall]

they fall into the Atlantic sea and NASA goes to sea and brings them back for another flight

[LucianaPacelli]

@hedkandi999 They fall back and are recovered by NASA

[FlamingBrad25]

@hedkandi999 They fall into the ocean and NASA has a special boat that picks them up

[leisulin]

What I've always wanted to understand is: they always talk about the engines throttling up to 104% of rated thrust. What's up with that? It sounds like what "rated thrust" means is the maximum normal thrust that the engines are supposed to be throttled up to. So it sounds like revving them up to a higher thrust than that to which they are rated would be like deliberately over-taching your car's engine. Why do they crank them up to 104%, why not always limit themselves to 100%?

[defenderoFreedom]

i never understood that either.

its like the justice system: How can a criminal receive 3 life terms??? or 150 years.

i dont think the engines are literally 104%. just a figure of speech. More similar to 95% in reality

[asdquet]

@defenderoFreedom

100% is the maximum EXPECTED value, however due to unpredictable variables you may need to exceeed expected values which means you're above 100%.

[defenderoFreedom]

@asdquet

i see what you're saying sir. Thank you!

[Cersia23]

In the American criminal justice system as far as I can recall a person gets time and half for good behavior. In other words for each day a person spends in prison and they don't act out or hurt or just do something against the rules they get 1.5 days credit towards their sentence. A person can get sentenced to one life terms or more if that person commits one or more crimes that carry a life sentence. This is most likely for only states that don't have a death penalty.

[Neptuneaus]

Your analysis is close. Ultimately, the thrust generated from the shuttle's 3 main engines exceeded the output that had been predicted. Rather than reconfigure their data, engineers determined that the engines exceed their initial projected performance by approximately 4 percent. Hence, the term "rated" thrust. All three engines can actually be throttled to approximately 109 percent in the event that one or two engines failed during launch and the additional thrust is needed to reach orbit.

[mrrmancunian]

I don't understand that either, though, it could possibly mean an extra 4% than what's needed in the design feature.

Similar to an aircraft when taking off, they don't always need 100% power input for take-off.

Just a guess though, don't take it literally lol.

[Hornfinger]

These one's go to 11

[FingerboardNoob21]

how long does it take to get to the moon>

[swatcapt11]

about three days

[1sts118]

Three days !

[leisulin]

if you're a photon, about 1.25 seconds

[defenderoFreedom]

is that true???

[SFEplaya]

does anyone know why they have to throttle down when they reach a point of maximum pressure?

[mach25man]

To relieve stress on the vehical

[SFEplaya]

thx

[frazier1983]

What happens to the Rockets that break off? Do they crash back into Earth?

[DukeNukem174]

They fall back to earth, into the ocean. That is why it rolls toward the ocean when it takes off.

[swatcapt11]

the two srb solid rocket booster fall back into the ocean and are pick up by the navy and reused the fuel tank burns up

[LesPaulMachine]

i have a space ship just like that but it's black

[IrishLincoln]

I love hearing them call out "16" at sixteen seconds and hearing the water sound supression system kick on and the hydrogen sparklers snap and then the hydro/ox stirs. WOW

[nyyankeefan2009]

it's 15

[mannyR37]

Fly Spacebat flyyyyy Little furry hero!

[Chrisjr2007]

loll it died :(

[clubkid43]

what is that spray coming from the shuttle?

[RobertsDigital]

coffee

[kacheek9059789]

why would it be coffee?you do mean the stuff spraying from the bottem of the rocket right?

[DecimoVongola]

He's just kidding. it is actually fuel. when the fuel caught fire, the thrust will get stronger. I think that what it is.

[RobertsDigital]

Yes its really coffee....The coffes is heated up and then used to power the rocket. The astronauts will drink some of it before launch.

[asdquet]

It's liquid oxygen coming from the pressure relief valves on each of the three liquid oxygen tanks.

[IrishLincoln]

That spray are sparklers used to burn off any excess hydrogen inside the main engines before takeoff. If they didn't burn it off it could build up and explode causing serious damage or loss to the shuttle system.

[xalbaje]

se obserba una estela de un avión en el minuto 2:48.

[ryuu5022]

何回見ても、素晴らしい！！

[wittmann]

my fiance can watch the launch from her front lawn :P

[k166a]

"full power for full science" ? NASA needs new writers...

[scrumdiddly]

Yeah. Those voiceovers are bad at the best of times...

[nyyankeefan2009]

powering the station for the researchers of tommrrow is better..

[HNDNV07]

@k166a: Yeah, no kidding! Can they not think of anything more intelligent too say, lol.

[IrishLincoln]

I like "Taking urine distilation units to a whole to height of tasty", but that's just me.

[rheaprinzmetal]

@k166a lol i agree cos i just heard another declare that the shuttle was "hoisting harmony to the heavens!" ahahaha

[doraldy1]

thats hella nice!!!thx bro!

[RJY4356]

That ditzy airhead gives the WORST countdown/ liftoff commentaries...EVER. Annoying as fuck!

[XSilvenX]

That "ditzy airhead" works at Nasa... I don't think I even have to say much more than that. Do you think they just take anyone there? I wanna see you try to work at Nasa...

[RJY4356]

Allright, here's what you don't know. I've watched every single shuttle launch beginning to end for 28 years now. I've been to NASA centers in Ohio, Maryland, Alabama and the Kennedy center in Florida multiple times, I've actually met the people that used to do this girl's job. She's only done it twice and she is the worst because she doesn't say much at all. I know what I am talking about. She is young and inexperienced and it really shows. The launch was so beautiful regardless.

[ydlanzitro]

if they pick me i will like T-10,9,8,7,6,5,4,3,2,1,7/8,3/4­,8/16,1/4 lol

[Jm4nu3l]

increible............

[electrocomm]

Great in recordings, but awesome LIVE !

[RJY4356]

Did you get to see it in person?!? Awesome.. It's been several years since I saw one there at the space center.
