NASA STS 123 Space Shuttle Endeavour Launch

[MrJimboygwapo]

they launched on my 10th birthday!

[SteveGad]

At 03:15 the site is checked out from above. Question is - by whom?

[Futurecop2012B]

CHECK OUT "UFO Disclosure, Revelations & the 2012 Connection" ON

YOUTUBE This is a compilation of evidence revealed by former military personnel,

astronauts, politicians, American presidents. This contains credible aired news

UFO footage. The compilation reveals knowledge of life beyond Earth + the current

ongoing presence and initiated contact which has being hidden from the public for

over 50 years + more.

I heard it's like ridding a speeding bullet but faster when it launches and I going to STS 133 LAUGHNCH on the causeway!

[bappoipp555]

i love this, im seeing a launch one dau

[HaloWarsFreak]

Thanks for uploading partially HD video.

[MrBennetzen]

What would happen before the launch if one of the astronauts on the pad was asleep?

[kilian2]

During STS-122 Atlandis used the OMS engine to provide an extra boost of power. Maybe due ta an heavy payload (Columbus).

[nakazatoGTR]

hey, has there been a shuttle flight with OMS(the 2 smaller engines) boost during powered ascent?

i fly orbiter, and the latest shuttle fleet 4.0 has this feature...

[EndeavourLaunch]

Ya Hermione, the Space Shuttle is Landing. Today.

[internationaljtm]

Endeavour looks cute :)

[hermione9105]

Awesome. I'm going to Kennedy Space Center next week. Pity they'll be no launch then )-:

[nakazatoGTR]

so, could you explain those weird glowing after separation of srb's up to MECO, and ET sep?

[bagabagabop1]

its the reflection of the vapor clouds from the main engines. its partly just main engine light but until they get to space, there is air. so the crazy speed 17000 or something creates the vapor clouds.

[pilotkyle2]

MECO means Main Engine Cut Off. Also ET sep means External Tank seperation. I was there for the launch and the sky lit up orange on lift off!

[bagabagabop1]

WHOOO GO DAD!!!!!!

[brianbogdany]

Every launch I see is simply amazing. I just can't believe these magnificent machines will be gone in two years time. I wish NASA would find a way to keep them until Orion is ready to fly. I'd rather fund the shuttle program for an extra 5 years than pay the Russians to send us up.

[theblue64]

i'm so glad that this went well! but.. finally after years for another shuttle to be built.. all they are doing is going to the space station. oh wow, how interesting.

[dorkmonkey]

the helicopter is going in circles ... it is a helicopter =]

[JSpread]

I was at the KSC Visitors' Center... great experience. Definitely worth the trip out. (They show NASA TV on a giant LED screen and broadcast the audio throughout the park for hours before launch... so as you're wandering around seeing exhibits you're listening to the countdown progress.)

[strangemenin2]

haha that is not a helicopter

[JSpread]

Yes it is... note the countdown clock moving faster as well. (The same helicopter was buzzing around in the hours prior... while we were on the bus tour, visiting the Apollo 5 and ISS buildings, it would occasionally pass by with it's spotlight on, patrolling the roofs.)

[nakazatoGTR]

then why are the people not giving it much attention?

hah, UFO freaks.

[tcartoon]

Why does the space shuttle glow when the main fuel tank separates? I thought the only thing glowing would be the fire from the rocket boosters, but for some reason you can only see that glow as the fire get some distance away from the rocket.

[kimmern123]

The glow is the plume from the main engines. You can see it during the first part of the launch as a clear, almost transparent plume due to the brightness of the SRBs drowning out the plume. As the air gets thinner the plume widens, then at the end of the launch the engines are throttled back to keep a 3g acceleration and then the plume comes closer to the engines again. The plume is very visible at night launches, as in this case.

[glennf45]

What does go for the plus x, no go for the pitch mean?

[JSpread]

The RCS problem they had - with one of the clusters in the nose - prevented them from pitching up as scheduled for the OMS burn. (The small burn they make to start a transfer orbit - to start chasing the ISS.) They needed time to figure out the problem. I think. :)

[kimmern123]

Go for the plus x means the commander (in this case Dom Gorie) is go for a forward translational maneuver by the RCS. This is done just after MECO to allow the cameras in the umbilical well on the underside of the orbiter to take pictures of the ET. No go for the pitch means they were not to pitch up after MECO to allow the MS1 and MS3 to take photo and video of the ET. This was a night launch and therefore nothing to take pictures of because of the darkness. That's why they were no go.

[MicPdEmcee]

the flying object visible in this video is the second light that i saw flying, the MSNBC footage shows another very agile craft the defy's inertia

[MicPdEmcee]

i noticed the craft LIVE! it was jaw dropping, absolutely amazing

[strangemenin2]

helicopter definitely cant maneuver like that

[cjracer1000]

2 bad it happened sooo aierly

[gondwana]

Thank you for launching Japanese spacecraft Kibo.

[alby85pd]

What's the light that appears on 04:38 minutes?

[kimmern123]

It's the plume from the Main Engines. It usually gets drowned out by the strong light from the Earth during daytime launches, but it's very clear and bright during night launches.

[bagabagabop1]

on the clock at banana creek of the actual time of the video. if your talking bout banana creek thats a swat helicopter that they fly after the launch. right before the launch they cleared the area of all people cuz obviosly you would die. so now they do a second check.

If your talking about the clock on this video, thats a kind of cloud thing that accumulates around the orbiter. It happens around Max Q, when the pressure on the orbiter is at its greatest. Its basically condensation.

[alby85pd]

Sorry... on 03:14 minutes... is a circle light. It fly around the PAD..

[watchnasatvcom]

The light buzzing around pad is a helicopter. This portion of the video is time compressed 500%.

[nathanmoeller]

Yep. It's the NASA security chopper.

[Skye7707]

Nasa TV didn't work so I'm glad I found this video here :)

[ascalia]

HOT DAMN is that COOL!!!!

[Kooleoone2]

Yeah, very fast uploading. Since I don't live in USA, this is the best way to follow what happens! And I just love to watch launches!

[hiroooooooooooo]

Good job NASA USA

[kevmccln]

Wow. Great footage. Thank you! Lets get the ISS completed!!!

[EternalStargazer]

Thank you for these almost poetic pictures from night launch of Endeavour!

[makdidly]

Awesome, God speed fellows!

[piergiorgiovico]

dear friends,fantastic launch you are GREAT!! please me sub...in my channel! thanks,piergiorgio.

[Zarjulius]

Awesome, thanks for uploading so fast
