has tested scaled models of the (Mars Ascend Vehicle) of the (Mars Sample Return) mission at the Marshall Space Flight Center wind tunnel facility.

Despite it being only 24 inches long and 14 inches in height and width, the tunnel can achieve supersonic speeds of up to Mach 5 (about 3,800 mph).

please anyone I need a +1 level explanation for my curiosity sake then what is available in this article

Why is the "nozzle" for the spinning? Beyond just stability.

A Rotary engine?

@AkaSci help please? Really curious as to the why

@AkaSci

thank you! ❤️ appreciate your quick response and detail, and your previous posts

Just seemed odd to me to see it spinning on the test stand. I thought there would more more reason then just stability

I suppose it doesn't matter for recovery if the payload still has any rotation while in orbit. as i doubt the spin motors would perfectly cancel each other out. :thonking:
