Godspeed Endeavor (day late!) by canaveralgumby on 10 August 2007 12:48am
 
I don't know if I'm coming or going, but Endeavor had a great launch yesterday, eveything's a-ok so far. Their only mission is continued construction on the International Space Station.

Commander Kelly is from NJ so eveything will be fine, or fughetaboutit.

See the above link for general mission news. Also, here's an update about the insulation inspection:

Yes ,it was a great launch, but why,to me,a Brit, do you keep having bits of packaging fall off?

I know that Anne is going to love me for this one, but sorry...the space shuttle Endeavour is named after Capt. James Cook's ship Endeavour. This is why Endeavour has and should have the British spelling.

Good luck to all.

"I know that Anne is going to love me for this one"

Why?

In fact it IS spelled WITH the "U". Lazy-ass, dyslexic American that I am, I missed it. Sorry.

It's been spotted in England! One mile north of greater-London-at-its-most-north-east-point, on Sunday 12/8/07, at 10.00pm. We were at a restaurant there & staff had actually seen it blazing in the sky - they were really thrilled - so I hope it's still doing OK

It's complicated but I'll give you the overly-simplistic "dee dee dee" answer, as only I can!, until I find a good link...

There is liquid oxygen or LOX in the external fuel tanks. As it sits on the launchpad awaiting liftoff, the external tanks develop frozen condensation (even though it's hot outside, it's BLEEDIN' cold inside).

The heat and motion of liftoff break up the condensation into chunks, which fly off the tanks. The heat, unfortunately, does not completely melt the condensation in time to just evaporate it. Many many chunks hit the shuttle; a very few damage the insulating tiles.

That is what happened to Columbia. It did not effect the flight until re-entry. The 2,000-plus degree F heat of re-entry got directy to the shuttle and normally benign gases in the shuttle combusted.

The TILES are made of this incredible material which is really light in weight, necessary for the vehicle to get off the ground. It repels the heat of re-entry, does NOT absorb it. If you ever get to visit any NASA visitor centers, you can see the demonstration. A person holds a small tile on their hand and turns a blow-torch on their hand. The tile repels the heat and you can touch the tile immediately, it's just room temp.

The "foam" which comprises the tiles is a solid, but softer than a shard of ice. And THERE's the problem.

There, how'd I do?

They seem confident today that the exposed part of EndeavoUr would not pose a danger during re-entry. The reports say that NASA is deciding whether or not to have the astronauts fill it in up there. WHETHER OR NOT? If I were up there I would just DO it! What'll they do, fire me?!

Long but well-written explanation:
