Traction
In space and astronautical engineering, traction refers to the force that is applied to a spacecraft or a rocket to move it forward. Traction is generated by the propulsion system of the spacecraft or rocket, which can be either chemical or electric. Chemical propulsion systems use the energy released by the combustion of a fuel and an oxidizer to generate thrust, while electric propulsion systems use electric fields or magnetic fields to accelerate charged particles and produce thrust. Traction is a critical parameter in space missions, as it determines the velocity and trajectory of the spacecraft or rocket. The amount of traction required depends on the mass of the spacecraft or rocket, the distance to be covered, and the desired velocity. Traction can also be affected by external factors such as gravity, atmospheric drag, and solar wind.
