I can't get over the size of the LOX feedline when seen close up. :cool:

It looks large, but don't forget that a good portion of that total diameter is due to insulation/foam surrounding the actual pipe itself.

Talking of Large.. are there any other large pieces of foam that have not been removed yet.. thinking brackets here, like IFR/PAL/LOX feadline/Bipod Ramp  etc.. see a trend?

... All foam is now removed from the four brackets, with re-application starting today...

ET-122 was damaged by hurricane Katryna in 2005 at MAF

The actual diameter of the pipe itself is 17 inches or about 1.5 feet. Approx. how thick is the foam surrounding it?

I believe the foam is about 2 inches thick wherever it is applied.  And that's a shame about ET-122.  How bad was the damage (obviously it was bad enough to prevent the tank from ever being flight-worthy)?

Thanks Nathan..nice to know!!

I agree, at least 2", possibly 3.5" thick (rough gauge looking at all the LOX line pics available with a person or something else to determine the outer pipe diameter); the final pipe diam. appears to be around 24" or slightly larger.

Good deal.  I bet James (Lockheed) could elaborate, but let's save it for Shuttle Q&A.  Don't want to stray from the topic too much We're looking at a pre-dawn landing on this flight.  SFN's information, assuming an 11:38 am EST October 23 launch and a November 5 landing, shows them coming into KSC at 5:15 am EST.

No- I am looking for other large pieces of foam, that have not been removed...i.e are we just left with acreage foam? and this small fix, in the world of foam on the tank ?

I'm sure the rest of the foam is still on the tank.  But, as per Chris' post, all the foam in question has been removed.

[Chris Bergin]

All of the big debris sources were removed even before this flight. This was a freaky incident that a small piece managed to fall off, with some denser SLA, bounce off the strut at the right time, at the right angle, to hit the TPS at an angle.

Regardless, all the foam is off, and they are building up the foam (with no SLA in it) on the brackets.

Didn't need to, but when they found cracks (and as per L2, one big ass crack in one of them) in the brackets, they had to then remove and repair on four ET-120 and one ET-125 brackets.

And still cause relatively minimal damage to two tiles in a non-critical location.

But man, the attention that got from NASA!

It got the correct and necessary attention from NASA. the overblown response was from all the armchair astronauts and news media looking for blood. but I digress

[Lee Jay]

Yeah...I agree.

Speaking of which, the next article will show some of the comments from the main Shuttle managers on those reports with armchair astros If you're sick of negative media, you will enjoy it.

[Far Reach]

Oh sweet, you're running the Wayne Hale and Steve Poulos comments from L2?!

[Chris Bergin]

Yep, but I'm getting the latest in on Endeavour processing before finishing it (will be tonight).

Back to STS-120 Processing:

The payload canister is in the SSPF. I bet they'll load Harmony within the next few days.
