Mariner 2 225 N anhydrous hydrazine retro-rocket

Mariner 2 used a 225 N monopropellant anhydrous-hydrazine retro-rocket for maneuvers. JPL describes the related Mariner trajectory-correction hardware as a liquid-fuel hydrazine motor with a nitrogen pressure system, catalyst, and nitrogen tetroxide starting fluid.
