ISS Irony

That is dumb too. What idiot wrote that?

In the void of space water is a gas.

They were damaged by water, but it was DOWN HERE, at the pad.

And any that remained upon entry into the vacuum of space may have damaged tiles simply from the gasification taking place.

"Allow to fly".

That says that the tiles are wet ON THE PAD.

The only moisture left in space would be trapped moisture. Water UNDER the tiles can freeze and crack a tile.

The rest gasses out.

That's what happens when it rains.

You snipped you own lines:

so I put them back for you.

You were wrong, as always.

It was meaningless tripe the last two times you said that dumb shit too.

Real engineers know how to operate any gear.

I'll bet you don't work on your own bike either. How sad.

nooks and crannies are not entrapments.

The problem was with trapped water at the tile/epoxy/ship interface. Breaks there cause entire tile segments to release.

Easy problem to solve. Just impregnate them with aerogel.

It is only needed on the way up. Doesn't matter if it burns or boils out upon return. We'll stuff more. The weight is near nil. Perfect solution.

I think you are mistaken, the unsymmetrical dimethyl hydrazine (USDMH) = and red fuming nitric acid (RFNA) hypergolic liquid combination has been used since the early Atlas/Agena days (early 1960s). For extra credit follow up through "hard starts". LH2-LO2 has other additional start considerations that make it non-useful for vacuum restarts.

?-)

Clouds of nasty RFNA coming toward your town is a very bad thing.

Causes you to change your procedures too... :-)

If you happen to be a maker of the stuff.

Battery plants could take a lesson from them. Or at least one.

You really don't have two brain cells to rub together do you?

We should have built one as an experimental vehicle, without the expense of a cargo bay.

That would have been enough to teach us what we learned from the first shuttle - that it wasn't worth it. Then we proceeded to build a fleet of them because most voters like to see astronauts go up and don't have the wit to even care about discovery.

We could have had a constellation of Hubbles and an army of Mars rovers, and things we don't have at all like probes flying through Jupiter and swimming through Europa.

You're an idiot. Always an idiot, you are.

I'd imagine that there's plenty of people who will give him a buck to go away.

orbit.

Yeah, I knew I was on real thin ice when DimBulb agreed with me.

orbit.

He's AlwaysWrong, which is remarkable, if you think about it. Even an idiot would be right now and then, purely by accident.

John

Hilarious. Playing with words, badly, to pretend that you are not AlwaysWrong.

How's the dollar-bill-magnet experiment coming along?

John

Tossing it in front of a moving truck isn't exactly 'giving it to him', is it?

He's more like the mouthy little rooster that wasn't afraid of the chicken hawk, even though he was completely defensless. Foghorn tried to keep him out of trouble, with little success.

The force water vapour can generate is strictly limited by its vapour pressure, and if the tiles were losing water by evaporation while in orbit, the rate of loss would be limited by the rate at which heat could flow into the tile to supply the latent heat of evaporation.

During re-entry the tiles got a bit hotter, and any residual water could have generated quite large forces when it got around to evaporating.

I don't suppose you ever heard of comets.

Mostly ice. Billions of years old. In space.

John

What kind of janitor hasn't heard of Comet? :)
