Well, there go NASA’s gold medal chances.
Seriously, though, this bit seems odd:
Gaps, or voids, were often left, and tests done since the Columbia accident have shown liquid hydrogen could seep into those voids.
“Liquid hydrogen”? If liquid hydrogen was seeping into a void beneath the bipod ramp, I’d think the foam void itself would be the lesser concern. I suspect that should have been “liquified air”.
