Usually small rockets are used to spin up the spacecraft and rocket then fire the rocket and send the craft off. Rockets and spacecraft that use spin stabilization: The Jupiter-C and Minotaur V launch vehicles used spin-stabilization. The upper stages on both system employ spin-stabilization to stabilize the system during propulsive maneuvers ...
Propulsion system thrusters are fired only occasionally to make desired changes in spin rate, or in the spin-stabilized attitude. If desired, the spinning may be stopped through the use of thrusters or by yo-yo de-spin. The Pioneer 10 and Pioneer 11 probes in the outer Solar System are examples of spin-stabilized spacecraft.

De-spin is needed since some final stages are spin-stabilized, and require fairly rapid rotation (now typically 30-60 rpm; some early missions, such as Pioneer, rotated at over 600 rpm [2]) to remain stable during firing. (See, for example, the Star 48, a solid fuel rocket motor.) After firing, the satellite cannot be simply released, since ...

The flight of the Honest John is stabilized by a spin that is imparted to the rocket by spin rockets after the round leaves the launcher. The XM51 Little John rocket flight is stabilized by applying spin to the rocket while on the launcher, just before firing. This manual method of stabilization was called "spin-on-straight-rail" (SOSR). [1]
In the heavy-hole spin system architecture within the double quantum dot, these quantum gate operations achieve quantum state fidelities as high as 99%. Price Action : HOLO shares are up 68.3% at ...
