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.

“Short of a wholesale reform of college athleticsa complete breakdown of the whole system that is now focused on money and powerthe womens programs are just as doomed as the mens are to move further and further away from the academic mission of their colleges.... We have to decide if thats the kind of success for womens sports that we want.”
