There are a total of 34 ice frost ramps on the external tank.

There are certain risks involved. You could damage the tank.

That tank we have to do a number of things to, at the minimum removing and replacing the PAL ramps, re-working the bipod closeout area where we think the wire may have actually allowed cryogenic ingestion of air to condense in an area, ... We have a number of things that we've got to do before we're ready to do that work.

Fire and Ice
Some say the world will end in fire,
Some say in ice.
From what I’ve tasted of desire
I hold with those who favor fire.
But if it had to perish twice,
I think I know enough of hate
To say that for destruction ice
Is also great
And would suffice.

Personally , I did not expect any large pieces of foam to fall off the external tank

We've had 10 poles, we've won four races - that's more than anybody else has.
