NASA Atlantis STS-125 Shuttle Launch 5-11-2009 - To Repair the Hubble Telescope

[overlord9278]

thanx for the amazing shuttle footage. sad to see NASA retire them. end of an era!

[angelgirl7473]

3300 mph~!!! wow

[blazeablunt4200]

11,000 pounds per SECOND!

[crankdatian14]

i was htere

[overheadcam32]

What an amazing vehicle. The engineers that came up with it sure had their act together along with all of the people that have maintained it over the years. Pride of the USA! I got to see the launch from the not so illustrious clarion inn in titusville!

lol

[propaghandi2]

i couldnt agree more, i am canadian and i am proud to have the canadarm up there....props to the americans for this awsome vehicle!

[J444123]

Beautiful!

[chuckn11]

just before lift off and the engines come on, something is spraying sparks or something into the area where the thrust is, what is it and wat is the purpose?

[mach25man]

Spark igniters are to burn any pockets of hydrogen that form under the orbiter. Dont want little explosions under there !

[CrowServo3000]

thats part of the launch pad, the sparks are there to ingite any stray gases to keep them from building up so when teh main engines come on any chance of an explosion has been dimished

[bige3az]

Video of launches have come along way since the 80's. The shuttle belly cam really gives you a new understanding of how fast that sucker is going. Godspeed to anyone who straps one of those things to their ass.

[sundenis]

Cool:)))

[Dakamum]

What is " Area Of Maximum Dynamic Pressure"?

[acerwentbad]

Maximum Dynamic Pressure or Max Q is the point at which the shuttle's frame undergoes the most mechanical stress. I believe this occurs at about 35,000 ft or so for the shuttle. That is why the shuttle throttles down it's main engines to ~72% during Max Q. Once it passes through the area of Max Dynamic Pressure the shuttle can then throttle up the main engines to 100%.

[F22DarkRaptor]

More the altitude is low, more the athmosphérique pressure is hight.

The area of the maximum Dynamic pressure is the area where the shuttle is the big air rapport of speed pressure - athmospheric pressure (sorry i suck in English ^^')

[SeKK0]

WOW!!!

[SeKK0]

WOW!!!

[oxcoma]

Watch closely between 6:48-6:49 in the left corner when the cam shows the eart surface from the Shutlle main Fuel tank it looks like a small black dot what is it a fragment or a UFO :)

[bgamelson]

That is a small piece of foam coming off the fuel tank.

[jeanbascout]

I hope that didn't damage the shuttle, like the one happened to Columbia...

JUST DO IT IT'S SCARY!!

[ALPKIDS]

Every single time that I see the launch I am amazed. Thanks for posting.

[bigjohnmfc]

went 2 ksc last summer still think about it waz an amazing place one thing bugs me on our 2nd or 3rd stop on tour bus we visited huge observation deck is 39a the one on my extreme left or is that 39b cn any one help. thanks we were standin n the top deck lookin at both shuttle launch pads,

[Kodos13]

39B is further to the North. (your left) It's the one with the 3 new lightning towers around it.

[bigjohnmfc]

came over from scotland last summer visited ksc never a day goez by without thinking about that incredible place , one thing bugs me though we were on the 2nd stop i think on the tour bus when we visited a huge observation decklooking at the launch pads from high up in the deck is 39a the one on the far left.

[RandyLayhea]

view from 6:14 and on in fast motion.

[cycler07]

seen both shuttles on the pads just 4 days before atlantis went up i was amazed them people have guts

good luck guys

[green2697]

I saw this live at school because we went to NASA in Houston,Texas on Friday

[jreal15]

Can anyone see where the sound barrier was broken? I can't tell.

[Neptuneaus]

At about +5:10 into the video.

[TheFox1968]

Looks like another piece of foam dislodged from the external tank at 6:48 min

[Neptuneaus]

The vehicle is too high in altitude for foam liberation to be an issue at that point.

[TheFox1968]

Looks like another piece of foam dislodged from the external tank on the left side at 6:48 min

[Etkar2008]

I saw this live yesterday.

[pegzley]

cool

[Crittijr]

cool

[VirtualRealities]

We can't let them shut down the Shuttle fleet.

[Neptuneaus]

If we want to go to the moon, Mars, and beyond, we have no choice -- shuttle can't do it. Trust me, I'm sentimental about retiring the fleet also. I've seen every shuttle flight since the first in '81.

[dmana3172]

I'm very anxious, waiting to hope there will be an interstellar space travel or travel to another galaxy. I hope we will be alive by the time the spacecraft is built.

By the way, I want to add that I'm going to be an astronaut, and I'm preparing for an interstellar mission to Gliese 251. The launch date is somewhere in 2010 :-D

[hogey74]

@VirtualRealities nah as much as I love these machines, they were not what NASA wanted right from the start and something better will come along before too long. The new one looks like a backward step, being simply a bigger version of the apollo system, but other people are on the case. Who knows, a private effort done by enthusiasts like in Denmark might be the way?

[spygrip]

That was Amazing!!!

[reginald2367]

Once again I`m in tears with pride. Rock on NASA., Rock on U.S.A.

[gman0productions]

alright!

[courtk1]

Awesome. People at their best.

[techdude49]

Great video. Thanks!

[macklec123]

Beautiful launch. Here we come Hubble.
