Assuming that's a LOX leak/dump - I'm surprised there hasn't been a fire or a "boom" yet ...

Air doesn't combust with LOX by itself AFAIK. Would have to be a spark on the rocket itself to catch the metal on fire.

Usually on vehicle vents, the gas shoot out horizontally.

The second stage is venting GOX

Ignition source and fuel required. If it's evaporating before it hits the ground, it's unlikely to be an issue. Even if it hits the ground, there have been a lot of lessons learned with respect to preventing LOX from contacting hydrocarbons or other potential hazards.

The second stage is venting like a typical rocket

Venting from the top now..

Any guesses as to what damage if any to rocket resulting from a long duration venting exposure ??.

They cut the feed. Something pretty bad then?

mlindner · « **Reply #108 on:** 11/21/2013 06:16 pm »

Oh they turned off the cameras!

Uhhhhhhhh... What?

somebody made a phone call

Whoa! Screen went full grey and then this!

Is that a suggestion that the first stage is NOT venting like a typical first stage? Certainly doesn't seem to be normal to me, but I didn't watch the Cassiope launch to see what the v1.1 looks like "normally".

Seems that the PR spin will be in......

mlindner · « **Reply #114 on:** 11/21/2013 06:17 pm »

I still have two feeds still going though. The camera is pointing at a white tarp though.

What's the fault tolerance for that much LOX against the skin?

Zaran · « **Reply #116 on:** 11/21/2013 06:18 pm »

If it was a tank rupture, would you expect it to vent that heavily for as long as it has been?

Looked to me, not that I have any in depth knowledge of the systems in place here, that the plume was originating near were I believe the umbilical are connected to the first stage, might be a bad connection there perhaps?

Chris Bergin · « **Reply #117 on:** 11/21/2013 06:18 pm »

Hmmm, this was the last shot before they cut the feed:

(Copy all below on tarp...good!)

sdsds · « **Reply #118 on:** 11/21/2013 06:18 pm »

Nice of the camera operator to first pan away, then cut the feed. Thus assuring us the camera was not damaged....

mlindner · « **Reply #119 on:** 11/21/2013 06:18 pm »

NVM they switched it to the weather camera now.
