#NASA has tested scaled models of the #MAV (Mars Ascend Vehicle) of the #MSR (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).
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 #MAV payload still has any rotation while in orbit. as i doubt the spin motors would perfectly cancel each other out. :thonking:
🚀🔥 La NASA a testé avec succès les moteurs de la fusée à 2 étages "Mars Ascent Vehicule". Le #MAV est la 1ère fusée qui doit décoller de #Mars pour envoyer les échantillons collectés par #Perseverance vers l'orbiteur qui doit ramener sur Terre la capsule de ses roches martiennes.
"Mars Ascent Vehicle Second Stage Test: A development motor based on the second-stage solid rocket motor design for NASA’s Mars Ascent Vehicle (MAV) undergoes testing March 29. [...] An important part of the NASA-ESA Mars Sample Return campaign, the MAV would be the first rocket fired off another planet."
