Is that the PV-12 valve at 0:18?, I remember seeing schematics of this and not having a clue how it actually opened and closed. Rest of the video was great too:)

@xytronite Yep that is the LH2 Inboard Fill and Drain Valve (PV12 for short) which is located in the orbiters Main Propulsion System inside the Aft Fuselage of Discovery. These 8-inch internal diameter Bi-Stable Pneumatic valves are classed as Criticality 1 hardware.

There are 4 of these valves inside the MPS, with the LO2 housing the PV9 LO2 Outboard Fill/Drain Valve and PV10 LO2 Inboard Fill/drain. The LH2 houses the PV11 LH2 Outboard Fill/Drain and the failed PV12 LH2 Inboard Fill/Drain.

Very informative video. I love living in Cocoa Beach cause i get to see the shuttle launches whenever they go off and I always have a good view. I wish the Grumman program was still up and running cause my grandpa tells me stories about all the fun he had working in it.

Where did you get those Video shots?

[interbartolo]

the video was compiled from a bunch of nasa internal video feeds, which I don't think are publicly available. only this compilation is publicly available.

[Patrickbenesch91]

Is there a simple way to get those?

[interbartolo]

no I dont think we release those videos to the public, sorry.

Very, very nice. I've seen some of the QuVIS launch videos, but never seen video Post-MECO from the ET Umbilical well.

Very nice, again. Thank you for editing and uploading! Please, do more!

My favorite shots are of the tail service mast umbilicals coming back from the orbiter and the doors closing. VERY NICE video all around! Thanks to whomever spent the time to edit this!

Wow! The first 2 minutes of this video shows camera angles during the launch sequence not seen before on NASA TV.
