Propulsion System
Juno uses a bipropellant Leros-1b main engine, manufactured by AMPAC-ISP in Westcott, UK. It uses hydrazine and nitrogen tetroxide for propulsion and provides a thrust of 645 newtons. It is fixed to the spacecraft body and is used for major burns. The engine bell is enclosed in a debris shield. Juno utilizes a monopropellant reaction control system (RCS) consisting of twelve jets that are mounted on four rocket engine modules. These thrusters are used for control of the vehicle’s orientation and to perform trajectory correction maneuvers.

Famous quotes containing the word system:
“He is not a true man of science who does not bring some sympathy to his studies, and expect to learn something by behavior as well as by application. It is childish to rest in the discovery of mere coincidences, or of partial and extraneous laws. The study of geometry is a petty and idle exercise of the mind, if it is applied to no larger system than the starry one.”
—Henry David Thoreau (1817–1862)
