Your picture doesn’t show any details of the sun, moon? Not a working model.
1. How did NASA go to the moon, if the firmament exists?
2. When NASA shows videos of earth, looking down from the space station, why is the earth not spinning at 66,000 miles per hour?
Before I answer your questions. Here are the quotes from the bible that give me the picture I have in my head.
Genesis 1:7 "And God made a
firmament, and divided the waters that were under the
firmament, from those that were above the
firmament, and it was so."
So I picture a round earth that is stagnant with waters under the firmament and over the firmament. What is between these two waters can be anyone's guess, hard glass, a layer of pure oxygen, or something else.
Then we have the flood.
Genesis 7:11 "In the six hundredth year of the life of Noe, in the second month, in the seventeenth day of the month, all the fountains of the great deep were broken up, and the
flood gates of heaven were opened:"
I picture the water above the firmament falling on to earth. My assumption is that the firmament is a gas layer not a hard service. This is why rockets need a certain speed to go from our atmosphere through the firmament to space.
Heliocentric is on the left and geocentric is on the right. (just a random video, a little off topic)
I picture the universe as a globe within a globe within a globe.
The center globe is the earth.
Around that is our atmosphere, with birds, planes, and clouds.
The firmament is here.
Around that is the moon's orbit.
Around that is the sun and planets.
Around that is the rest of space.
Now to answer your questions.
1) Did we go to the moon or not? If you believe that we didn't then, why ask this question. It doesn't really have to do with the shape of the earth. If we do believe that there is a space program, then to launch something past the atmosphere through the firmament, you have to do a bunch of calculations to figure that out. Which supposedly NASA has figured out, but I can neither confirm nor deny, because I am not an astrophysicist. Nor do I have the time to become one as a side hobby.

(laughing at myself)
2) I am not sure where you get that earth is spinning 66000 miles an hour looking at it from the space station. First do you even believe there is a space station out there? Do we know for sure the earth is spinning?
I don't know why I keep engaging.

(at me, not you)
