My dear readers,

of the paper cone.
Actually, no. Look at the lander design, it's low to the ground, which would make the center of gravity low in the cone, and thus centered on the
ablative shield. Llamas know this. Maybe even goats know this. One must wonder why Big-Brain does not know this.

to join the shell to the rocket.
Again, no. The ablative coating of the heat shield is made of a cork-like substance, which contains glass, silica, and other heavier materials, as
well as cork. This is coated onto a large, heavy, metal plate. This large, heavy, metal plate has a large, heavy lander attached to it, making the
whole thing very heavy indeed. Heavy things like to stay on the bottom. Gravity likes to pull heavy things down. Simple, like to feed a llama.
Originally posted by Big-BrainBesides the big velocity (20,000 kmph) creates a big aerodynamic friction more powerful than center of
gravity that forces the conical shell in this attitude:
And when it has reached a velocity that would overcome the low, heavy center of gravity, it releases the parachute, which causes drag on the cone.
This causes the cone to want to stay on top. It is similar to what would happen if you attached a parachute to the rear end of a goat and then dropped
it out of a jet at high altitude. Once the parachute was released, the goat would go down head first. The goat would then impact the ground with his
face. The llamas highly endorse this idea.
Now, have I been clear enough, or am you in need of additional sciences?
