The Lockeed SR-71 Blackbird flew around 2,200 mph and air friction heating of surfaces was a huge problem. How, exactly, is this rocket going to spin around in circles for about an hour until its speed eventually exceeds 5,000 miles per hour and not melt or fall apart from the heat?
It spins in a near-vacuum.

I saw your question was answered, but also keep in mind that the projectile/satellite only experiences frictional heating for 1 minute, far shorter than any re-entry vehicle...so just maybe they don’t get toasted...but they still have that huge g-force.
But given the g-force, if they can meet their claims, expect larger launchers, which would lower the g’s and thus allow additional (i.e., more sensitive) payloads.
