Overall view of the center of the interior of the thrust chamber.
At the center, note the injector. About
one radius of the injector out from the center is the location where the tubes
comprising the thrust chamber bifurcate, or
split in two.
Just outward from the bifurcation point, the tubes change color and then change
back to the original color. I don't know why this is but guess that that's
just what happens when an F-1 engine sits outside, exposed to the elements, for
The white blotches were present when we visited in both 2004 and 2005. I don't
know exactly what they are, but imagine they might be some sort of fungal
growth or insect cocoon.
