On-Orbit Orbiter OMS RCS Fuel Cells Payload Bay Crew Compartment ECLSS

Weight: 153,000 lb / 69,400 kg Height: 57 feet / 17.4 meters Length: 122 feet / 37.2 meters Width: 78 feet / 23.8 meters

O.M.S. (ohm-z) – Two OMS Engines – Use Hypergolic Fuels Fuel: Monomethyl Hydrazine Oxidizer: Nitrogen Tetroxide

R.C.S. – 44 thrusters on the nose and tail of the Orbiter – Same propellants as OMS

Demo Time

Three Fuel Cells provide electricity for the orbiter – Oxygen + Hydrogen = Electricity Water

Length: –60 feet –18.3 meters Width: –17 feet –5.2 meters Depth: –13 feet –4 meters Hitch a ride? –Not pressurized or temperature controlled Uses: –EVA and Cargo

Remote Manipulator System –RMS or “Canadarm” moves payloads and assists with EVA Orbital Inspection Boom –OIB is used with RMS to inspect heat- tiles for damage
