How to turn Niagara Particle System Physics Movement?

Hello,

So I made a particle system in Niagara for a space ship thruster effect, after attaching it to the spaceship engine, when I fly the spaceship up/down/side to side the particle system gets all crazy dragging streaks across the screen. I want to turn of the “physics”? on the system I guess, but don’t know how.

In simple terms I just want the particle system to not be affected by anything especially movement and just do its continuous loop without physics.

How can I do this?

Thank you in advance!
